--- Aldus PhotoStyler 2.0 Special Edition Readme --- This readme file contains information that was not available when the Aldus PhotoStyler Special Edition User Manual went to print. For your convenience, print a copy of this file and keep it with your PhotoStyler manual. The following topics are included in this file: 1. Upgrading to the full version of Aldus PhotoStyler 2.0 2. Corrections to the manual 3. The KODAK PRECISION Color Management System (CMS) 4. Installing to a network drive 5. Running PhotoStyler under Windows NT 6. Video cards and monitor calibration 7. Memory management 8. Sample files included with PhotoStyler 9. Opening and saving files and options 10. Using Clipboards 11. Object Linking and Embedding (OLE) 12. Using third-party plug-in filters 13. Installing import/export modules 14. Possible display error when using the Preview button 15. Cross-platform issues 16. Using Hue Only, Saturation Only, and Brightness Only options with CMYK images 17. Printing and other output ========================================================= 1. Upgrading to the full version of Aldus PhotoStyler 2.0 ========================================================= The full version of Aldus PhotoStyler 2.0 contains many features not included in this Special Edition. For more information about upgrading, refer to the brochure that is included in the PhotoStyler package, or choose Upgrading... from the Help menu. ============================ 2. Corrections to the manual ============================ Page 57, second paragraph, second sentence. This should read "The width of a video frame in NTSC format, an American standard, is 756 pixels. To determine your desired image resolution, divide 756 by the width of your source image." Page 84 describes using the Soft Proof... command on the File menu with RGB images. You can also use this command with indexed 16-color and 256-color images. Page 92, fourth paragraph, third sentence. This should read "Standard 35 mm formats are 2K, 4K, and 8K, or 2048, 4096, and 8192 lines per inch." ==================================================== 3. The KODAK PRECISION Color Management System (CMS) ==================================================== 3.1 You cannot turn the CMS off ------------------------------- The CMS is completely integrated into PhotoStyler and cannot be disabled. When you installed PhotoStyler Special Edition, it created a default CMS configuration that did not require you to choose any specific Precision Transforms (PTs). In this situation, the CMS operation is completely transparent. If you obtain some PTs for your system (as discussed in Chapter 1 of the Aldus PhotoStyler User Manual), you can customize the CMS to produce the best color output from PhotoStyler. 3.2. KPCMS directory location ----------------------------- When you install PhotoStyler, the KODAK PRECISION Color Management System (CMS) stores files in the directory \kpcms. If you already have a \kpcms directory, the installer updates the files. If you do not have a \kpcms directory, it is created on the same drive where you install PhotoStyler. If, after installation, you need to move the directory to another drive, you must modify the kpcms.ini file so PhotoStyler can find it. Perform the following procedure only if you need to move the directory and if you feel comfortable making changes to initialization files. 1. If PhotoStyler is running, close it before proceeding. 2. Move the \kpcms directory to the desired drive (it must be off the root directory). Do not move it to a network drive. For information on moving directories and files with File Manager, refer to your Windows documentation. 3. Locate the file kpcms.ini in the Windows directory. Open this file with Windows Notepad. 4. Locate the line DRIVE="C:" under the heading [KEPS Precision]. 5. Change the line to reflect the new location. For example, DRIVE="D:". Save and close kpcms.ini. ================================ 4. Installing to a network drive ================================ When you install PhotoStyler, a directory called \kpcms is installed off of the root directory. If you are installing PhotoStyler on a network drive and you do not have write-access to the drive's root directory, the installation will fail. Contact your system administrator for the proper access and try the installation again. ======================================= 5. Running PhotoStyler under Windows NT ======================================= PhotoStyler 2.0 is a 16-bit application and although it can run under Windows NT, it cannot take advantage of NT's 32-bit architecture. Some operations may be slower than when running under Windows 3.1. ====================================== 6. Video cards and monitor calibration ====================================== 6.1 Video card incompatibility ------------------------------ If you encounter problems running PhotoStyler, the first place to check for a potential conflict is with the video card installed in your computer. Change the video mode to regular VGA and try to duplicate the problem. If you cannot duplicate the problem, there is probably an incompatibility between the video card driver and PhotoStyler 2.0. Contact the card manufacturer and inquire about an updated driver. 6.2 Using the Monitor Gamma... command -------------------------------------- To get the best results when using the Monitor Gamma... command, the test image should fill as much of the screen as possible. Click the zoom buttons in the Monitor Gamma dialog box to size the image. If possible, stand at least two arms lengths back from the monitor while making the adjustments. 6.3 Monitor calibration devices ------------------------------- Do not use the Monitor Gamma... command to calibrate your monitor if: -- your video card has its own calibration software, or -- you have a separate calibrating device (such as a suction cup calibrator). You will get better results if you use the card or device to calibrate your monitor. ==================== 7. Memory management ==================== Since image files can be very large, the way you configure PhotoStyler's memory management significantly affects the performance of your system. How you configure your system depends on the type of work you do; if you routinely work with large image files, you may configure your system quite differently than if you always work with small files. You control how PhotoStyler uses memory by setting options in the Virtual Memory Management dialog box. Before adjusting these settings, please read the following description of how PhotoStyler uses memory. This information is critical when calculating the values for the dialog box. Note: Adjusting PhotoStyler's memory management settings not only affects PhotoStyler's performance, but may also affect other applications that are running at the same time as PhotoStyler. Under most conditions, the default settings are appropriate. Do not change the default settings unless you are absolutely certain it is necessary. 7.1 Windows and memory ---------------------- Your computer contains RAM chips that store program code and file information. Since RAM is a completely electronic device (that is, no moving parts), the processor can read from and write to it very quickly. Since many programs often need more memory space than available RAM, Windows lets you create a swap file on your hard drive. This is an area of unfragmented disk space that Windows treats as additional RAM. For example, if you have 8MB of RAM installed in your computer and you set up a Windows swap file of 4MB, DOS, Windows, and applications have 12MB of memory space in which to run. The swap file on the hard drive is called virtual memory. Because the hard drive is a mechanical device, the processor cannot read from and write to it as fast as RAM. The combined RAM and virtual memory is called the global heap, and represents the total memory available to Windows and applications. For more information about swap files and virtual memory, refer to your Windows documentation. 7.2 How PhotoStyler uses memory ------------------------------- PhotoStyler uses its own swap area inside the permanent swap file portion of the global heap. Because PhotoStyler can swap to and from the hard drive faster than Windows, it runs faster than if it relied on Windows memory management alone. A typical PhotoStyler swap area is larger than the RAM, but smaller than the global heap. As PhotoStyler's memory needs increase (for example, as you open additional image files), it fills memory in the following order: 1. The RAM portion of the PhotoStyler swap area. 2. The virtual memory portion of the PhotoStyler swap area. (Once this is full, the entire PhotoStyler swap area is full.) 3. Additional hard-drive space that you specify. Notice that after the PhotoStyler swap area fills, it does not fill the remainder of the global heap. To do so would consume all the memory available to Windows and other applications and could slow the system performance. Instead, PhotoStyler looks to other areas on the hard drive for additional virtual memory. (This also provides better performance since PhotoStyler swaps to the hard drive faster than Windows.) You can also specify the total amount of virtual memory PhotoStyler uses. This prevents PhotoStyler from using too much disk space when handling unusually large files. Note: The PhotoStyler swap area is not available to other applications. If you create too large a swap area, other applications may not be able to run. 7.3 How much memory does PhotoStyler need? ------------------------------------------ When you work with an image file, PhotoStyler needs enough memory to hold the image, plus buffers. The buffers provide working space for PhotoStyler. For example, if you apply an effect to an image, it holds the image in memory while it constructs the new image in the working buffer. Because of the need for working buffers, an image needs approximately three times its size in memory. Also allow about 4MB for DOS, Windows, and the PhotoStyler program. If you run other programs at the same time as PhotoStyler, you may need still more memory. 7.4 Tips -------- Create a permanent Windows swap file twice as large as the installed RAM (provided you have enough hard-drive space). You may get a warning message saying that Windows cannot use a swap file this large. Specify large, empty, defragmented drives for the Swap Path area in the Virtual Memory Management dialog box. Make sure no disk compression program is running on the drive. Avoid specifying network drives, as they are too slow. (If you must use a network drive, make sure no one else uses it for a PhotoStyler swap area; this can create network sharing violations.) Under no circumstances should you specify a floppy disk drive as a swap path. If you use a memory manager program, refer to its documentation for information on how it handles RAM and virtual memory. When in doubt, use PhotoStyler's default settings (that is, click the Default button in the Virtual Memory Management dialog box) for memory management. 7.5 Changing virtual memory settings ------------------------------------ To open the Virtual Memory Management dialog box, choose General... from the Preferences submenu on the File menu. Then click the Virtual Memory... button. Changes you make in this dialog box take effect immediately--you do not have to restart PhotoStyler. You set the size of the PhotoStyler swap area in the Memory Size for Image Buffers Usage box. You can select any value in the designated range; the minimum value is always set to 512K, while the maximum value varies depending on the available space in the global heap. 7.6 Calculating the best size for the PhotoStyler swap area ----------------------------------------------------------- There is no single best size for a PhotoStyler swap area. The size you set depends on several factors: - The amount of RAM installed in your computer - The size of the Windows permanent swap file - The sizes of the images with which you typically work - Whether or not you have any other applications running at the same time as PhotoStyler If you do not run any other applications at the same time as PhotoStyler, and if you typically work with large image files, set the PhotoStyler swap area to its maximum value. If you run other applications at the same time as PhotoStyler, check their documentation to find out how much memory they require for operation. Subtract this amount from the global heap to calculate the best size for the PhotoStyler swap area. If you typically work with small files and you have sufficient RAM, you may want to use a PhotoStyler swap area size that is less than the Default value. If your images and their working buffers all fit in RAM, you might consider disabling PhotoStyler's use of virtual memory. If you have a large amount of RAM (greater than three times the size of one of your typical images) and a sufficient amount of free, unfragmented hard disk space, set the PhotoStyler swap area equal to the size of the installed RAM. This prevents PhotoStyler from using the Windows swap file. Instead, it uses RAM and the PhotoStyler Swap Path, which is faster than the Windows swap file. If you're not sure about your memory requirements, use the Default value for the PhotoStyler swap area. You can always change it later if necessary. 7.7 To set the PhotoStyler swap area size ----------------------------------------- 1. If you do not already have one, create a permanent Windows swap file at least twice as large as the amount of installed RAM (provided you have enough hard-drive space). Refer to your Windows documentation for more information on virtual memory and creating a swap file. 2. Choose General... from the Preferences submenu on the File menu. Then click the Virtual Memory... button. 3. If you do not want PhotoStyler to use any virtual memory, check Disable Virtual Memory. You can still specify a size for the PhotoStyler swap area. 4. The size of the PhotoStyler swap area is set in the Memory Size for Image Buffer Usage box. Click Default if you want to use the default value. Otherwise, type in the desired value. 5. In the Swap Path boxes, type in up to four drive locations for PhotoStyler to use once the PhotoStyler swap area is full. For best results, these drives should contain large areas of open unfragmented, contiguous space. Make sure there is no disk compression program running on the drive. If you are not able to use an unfragmented area, increase the size of the PhotoStyler swap area so less of the swap path is needed. 6. If you want to limit the amount of virtual memory (that is, the amount of hard-drive space) PhotoStyler uses after its swap area is full, check Limit Size for Virtual Memory Usage and enter a value. 7. When all the settings are correct, click OK. Then click OK again to close the General Preferences dialog box. The changes to virtual memory take effect immediately. 8. If you notice that dialog boxes open slowly, you have probably set the PhotoStyler swap area too large (and as a result, there are few resources left for Windows). If this is causing problems for you, reduce the size of the PhotoStyler swap area. 7.8 Memory level reported in the status bar ------------------------------------------- The right side of the status bar indicates the amount of free PhotoStyler swap area memory. When this number falls below zero, PhotoStyler uses the swap paths specified in the Virtual Memory Management dialog box. ========================================= 8. Sample files included with PhotoStyler ========================================= PhotoStyler includes numerous sample files for you to use. These files are located in subdirectories off of the PhotoStyler directory, and are grouped according to what they are used for. \COLORS The \COLORS subdirectory contains 65 custom color files, grouped into four subdirectories. To load one of these files, press F10 to display the Color Palette and select Custom from the drop-down list. Then choose Load Colors... from the Custom Color submenu on the tool-drawer menu. \PALETTES This subdirectory contains 15 sample files that you can load into the Color Palette. Choose Load Palette... from the tool-drawer menu. \PATTERNS This subdirectory contains ten pattern files that you can use with the clone tool or the Fill... command on the Edit menu. To load a pattern, choose Content... from the Pattern submenu on the Edit menu. Then click the Load... button. These texture patterns were created for Aldus Corporation by Pixar. High resolution, seamlessly tiling versions of these images suitable for use in printing or slide production are available from Pixar by calling in the U.S. (510) 236-4000. \TUTORIAL This subdirectory contains the images used in the printed PhotoStyler tutorial. Refer to Chapter 2 of the User Manual for more information. ======================================= 9. Opening and saving files and options ======================================= 9.1 Opening an image from a Photo CD ------------------------------------ In the Open Image File dialog box, be sure to select PCD (PhotoCD File Format) in the List Files of Type list box. This lets you click the Options button to choose the resolution of the image. If you select All Formats in the List Files of Type list box, the Options button is not available. 9.2 Saving a mask with a TIFF file ---------------------------------- Some applications may experience problems when you import a PhotoStyler TIFF image that was saved with a mask--you may get an error message that says the image file is invalid. If this happens, it is probably because the application does not fully support the TIFF 6.0 specification. Contact the application's manufacturer and ask about an update to their TIFF import filter. 9.3 Saving a clipping path with an EPS file ------------------------------------------- You can create a clipping path by making a selection in the image and saving it as an EPS file with the Save with Mask option checked. Keep in mind, however, that the clipping path is bitmapped. If you place the image in another application (such as Aldus PageMaker) and resize it, the jagged edges of the bitmapped clipping path may become pronounced. To avoid this, make sure the image is the proper size before you save it in PhotoStyler. Then place it in the other application at its actual size and do not resize it. 9.4 The Preview option in the Open Image File dialog box -------------------------------------------------------- Normally you have to click the Preview panel to see the image thumbnail in the Open Image File dialog box. You can, however, make the previews appear automatically when the filename is highlighted. To do this, the file must be saved with a TIF preview (this is available only for TIF and EPS file formats). When saving the image, click the Options button in the Save Image File dialog box. Then check the Preview TIF option. Keep in mind, though, this will increase the size of the image file. 9.5 Opening images in other image-editing applications ------------------------------------------------------ When you save a TIFF image in PhotoStyler 2.0, information about the color management system (CMS) is embedded in the TIF file. If you then open the image in another image-editing application and save it, it will likely lose the CMS information. If you then open the image in PhotoStyler, it will apply a new monitor-space Precision Transform, and the image colors may not be accurate. 9.6 Opening an Adobe Photoshop image file with multiple alpha channels ---------------------------------------------------------------------- PhotoStyler 2.0 can open files saved in the Adobe Photoshop format (PSD extension). If the file was saved in Photoshop with multiple alpha channels, PhotoStyler reads only the first alpha channel and interprets it as a mask. 9.7 Changing the number of files appended to the File menu ---------------------------------------------------------- The most recently opened files are listed at the bottom of the File menu. By default, PhotoStyler lists five files, but you can increase this up to 16. Perform the following procedure only if you feel comfortable making changes to initialization files. 1. If PhotoStyler is running, close it before proceeding. 2. Locate the file pstyler.ini in the Windows directory. Open it with a text editor such as Windows Notepad. 3. Locate the heading [ROF] in the file. Change the first line under the heading to indicate the number of files you want listed at the end of the File menu. For example, if you want eight files listed at the end of the menu: [ROF] FMS=8 4. Save the changes and close the file. When you open a file, it is added to the top of the list (designated by "1."), unless it already appears elsewhere on the list. If there are more than nine files listed, the 10th is designated by the letter "a.", the 11th by "b.", and so on. This lets you use accelerator keys to select files as you would any other command on a menu. For example, press Alt+F to open the File menu. To select one of the first nine listed files, press that number. To open one of the other files, continue to hold Alt and press the corresponding letter. If that letter is already used as an accelerator key for another command (for example, "a" is used with Close All), press the letter again to highlight the filename. TIP: To open a copy of the file listed on the File menu, hold the Ctrl key while selecting the filename with the mouse. To open all the files listed, hold Shift while selecting any filename. To open copies of all the files, hold Ctrl+Shift while selecting any filename. ==================== 10. Using Clipboards ==================== 10.1 PhotoStyler Clipboard -------------------------- You can save the contents of the PhotoStyler clipboard to a file using any file format that is valid for that image type. You can also save the contents to the CLI format, which is the native format for the PhotoStyler Clipboard. The format you choose depends on what you intend to do with the saved Clipboard file. If you intend to load the file back into the PhotoStyler Clipboard at a later time, you should use the CLI format as this retains all the Clipboard information (including the shape of the selection). If you intend to place the Clipboard file in another application, choose the format that works best for that application. 10.2 Windows Clipboard ---------------------- The Windows Clipboard only supports rectangular images. If you copy a non- rectangular image to the Clipboard, it is constrained to a rectangular bounding box and the area outside the selection is filled with the current background color. When you copy an image to the Windows Clipboard, PhotoStyler does not immediately place a Device-Independent Bitmap (DIB) or Device-Dependent Bitmap (DDB) on the Clipboard. Instead, PhotoStyler waits until you paste the Clipboard contents in another application. At that time, PhotoStyler determines the best image format for use with that application, and places the appropriate information on the Clipboard. Because of some limitations with the Windows Clipboard, there may be some restrictions as to the image types to which you can paste the contents. Likewise, the CLP file format does not support every file type. The following table lists the limitations. Image type Image types that Saved to CLP copied you can paste to file format Notes ------------------------------------------------------------ CMYK CMYK, RGB, Gray RGB (1)(2) RGB RGB, Gray RGB (2) Grayscale RGB, Gray Indexed 256 (1) Indexed 256 RGB, Gray, Indexed 256 Indexed 256 Indexed 16 RGB, Gray, Indexed 16 Indexed 16 B & W RGB, Gray, B & W B & W Notes: (1) Since DIB does not support CMYK or grayscale, they are converted to RGB and indexed 256, respectively. (2) If the computer's display mode is set to 256 colors, both RGB and CMYK images will be converted to indexed 256 when saved in the CLP format. ====================================== 11. Object Linking and Embedding (OLE) ====================================== Be careful not to break the OLE link when you are working on an image in PhotoStyler. When you select Insert PhotoStyler Image in the destination application, PhotoStyler starts and the Open Image File dialog box appears. If, for example, you open an RGB true-color image and then convert it to CMYK, the converted image is not linked to the destination application if it opened in a new window. To ensure that the OLE link is maintained, make sure no check mark appears next to New Image on the Convert To submenu on the Image menu. That way, when you convert from one image type to another, the converted image is in the original image window, and the OLE link is not broken. ===================================== 12. Using third-party plug-in filters ===================================== You can use any third-party plug-in effect filters compatible with PhotoStyler or Adobe Photoshop for Windows (for example, Aldus Gallery Effects). To install the filters on your hard drive, follow the instructions included with the filters. To link filters to PhotoStyler, follow the procedure below. When they are linked, they appear as submenus on the Effects menu. Keep in mind, however, that linking a large number of filters can cause PhotoStyler to take longer to start. Note that this procedure only affects which plug-in filters PhotoStyler uses; it does not delete the filters or affect how they are used by other programs. 1. If PhotoStyler is running, close it before proceeding. 2. Locate the file ulead.ini in the Windows directory. Open this file with a text editor like Windows Notepad. 3. Locate the heading [PLUG IN]. If this heading does not exist, go to the end of the file and create it on a new line. 4. After the heading, add a line that points to the directory where the filters are located. The line must begin with "PLUGINDIR1=". You can add up to nine lines, just remember to increment the number in each line. For example: [PLUG IN] PLUGINDIR1=c:\ge PLUGINDIR2=c:\filters PLUGINDIR3=c:\effects 5. Save the changes to ulead.ini. ==================================== 13. Installing import/export modules ==================================== When you install import and export modules, they appear under the Import and Export submenus on the File menu. Installing a module typically involves running an program that "attaches" the module to PhotoStyler by modifying the pstyler.ini file (refer to the instructions that come with the module for exact details). By default, the pstyler.ini file is placed in the Windows directory. Some modules, however, may look for the file in the PhotoStyler directory; if it is not found, the module installation fails. To move the initialization file to the PhotoStyler directory, follow these steps: 1. Choose Private Initialization File... from the Preferences submenu on the File menu. 2. In the Private Initialization File dialog box, change the directory to the one where PhotoStyler is installed. 3. Type in a name for the initialization file. Make sure Save Current Options and As Private INI File Next Session are both checked. Then click OK. 4. Exit PhotoStyler and run the module program. The module will appear under the appropriate submenu the next time you start PhotoStyler. ======================================================== 14. Possible display error when using the Preview button ======================================================== For some filters and effects, clicking the Preview button in a multi-preview dialog box displays results that differ when you click OK. This can occur when (1) the image is zoomed out past 1:1 (for example, 1:3), AND (2) the dialog box is expanded (the test panels are visible), AND (3) the auto-update button is not highlighted (auto-update is off). When the image is zoomed out past 1:1, PhotoStyler uses a smaller buffer for the screen display. While this smaller buffer increases PhotoStyler's speed, it may not be able to display the previewed effect accurately. Whether or not this is noticeable depends on the characteristics of the image and the specific filter or effect used. If you experience this problem, change the view of the image to 1:1 or greater. Or, click the auto-update button (to turn it on) before you click the Preview button. ========================= 15. Cross-platform issues ========================= When you save an image in the TIF format, you have the option of saving it as a Macintosh file. When you do this, the resulting file will appear in the Macintosh Finder as a PC file. You can still use the file with any Macintosh application that supports TIF images, but since it does not have a resource fork (a component common to Macintosh files), it will not be identified as a Macintosh file. ========================================================================== 16. Using Hue Only, Saturation Only, and Brightness Only options with CMYK images ========================================================================== Several PhotoStyler tools and commands let you paint or fill colors with settings of Hue Only, Saturation Only, or Brightness Only. When one of these three options is used with a CMYK image, however, the other two components may change slightly. For example, if you use the paintbrush on an area of a CMYK image and the Brush option is set to Hue Only, both the saturation and brightness components may change slightly. This happens because of the image transformations that occur "behind the scenes" when you perform an HSB action on a CMYK image. When you adjust an HSB characteristic of a CMYK image, PhotoStyler translates the CMYK data into RGB and then into HSB. This HSB data is then converted back into RGB and finally CMYK. The instances where the data is going back and forth between RGB and CMYK can introduce color shifts due to gamut limitations of the target output device. To maintain the most accurate colors, perform all your editing before converting the RGB image to CMYK. ============================= 17. Printing and other output ============================= 16.1 Adobe PostScript driver support ------------------------------------ PhotoStyler 2.0 can use the Adobe PostScript driver and take advantage of its enhanced functionality. 16.2 Film recorders ------------------- PhotoStyler 2.0 supports output to film recorders. However, the film recorder manufacturer or dealer is responsible for supplying the proper Windows- and PhotoStyler-compatible driver. 16.3 Printing to the HP LaserJet IV in PCL5e Mode ------------------------------------------------- The drivers for this printer are very specific in resolution: one driver sets the resolution to 600 dpi and the other driver sets it to 300 dpi. PhotoStyler cannot change a 600 dpi driver to 300 dpi. In the Print/Options dialog box, you will see resolution settings labeled High, Medium, Low, or Draft; these refer to the printer's graphics quality. A setting of High prints the correct grayscale image. Any other setting results in printing a 1-bit black-and-white image. 16.4 PCL devices ---------------- When you print to a PostScript device and you select the Emulsion Down option in the Print dialog box, the entire image--including the title and printer marks--is reversed. PCL devices, however, can only reverse the image; the title and printer marks will remain right reading. If you need to see the precise Emulsion Down results, you must send the image to a PostScript device. A similar problems exists with the Negative option in the Print dialog box. When you select Negative and send the image to a PCL device, only the image appears as a negative; the title and printer marks are not negative. For a complete negative image, you must send the image to a PostScript device. 16.5 Selecting the Halftone By PhotoStyler option ------------------------------------------------- Whenever you select this option, you will notice slower performance. There are many additional calculations taking place to match image resolution to printer resolution and halftone variations. All this additional information is sent to the printer driver, resulting in slower printing. 16.6 Dot Gain ------------- Dot gain is a complex issue due to the implementation of the KODAK PRECISION Color Management System. If you need to adjust dot gain after an image has been converted to CMYK, follow this procedure to ensure that the image you see on screen is the most accurate representation of what will be printed. NOTE: You typically should not have to adjust dot gain unless specifically requested to do so by your service provider. 1. Reopen the original RGB version of the image. 2. Choose Options... from the Print submenu on the File menu. 3. Click the Dot Gain... button to open the Dot Gain dialog box. 4. Set the level of gain specified by the printer. Then click OK. Click OK again to close the Options dialog box. 5. Convert the image to CMYK following the normal conversion steps. By setting dot gain before conversion, the gain is calculated into the conversion table. You will not see a change in the image on screen but you should get the desired adjustments when the image is printed. The reason you will not see a change on screen is because you are trying to adjust the printer to match your screen display--not adjust the screen to match the printed image. 16.7 AGFA Imagesetters: using the AGFA 3.55 driver -------------------------------------------------- This is a proprietary driver created by AGFA and is a modified version of the Windows 3.55 driver. In order to best utilize the driver's ability, PhotoStyler disables certain functions in the Print/Options dialog box. To set resolution, halftone frequency, and halftone angle, you need to use the Windows printer controls. (If you set the halftone frequency and angle in the PhotoStyler Print/Options dialog box, you may not get the expected results.) To access this screen, follow these steps: 1. Choose Printer Setup... from the Print submenu on the File menu. 2. Make sure the AGFA device is highlighted in the Printer Setup dialog box. Then click the Setup... button. 3. Click the Options... button. 4. Click the Advanced... button. 5. Enter the information in the Graphics section of the Advanced Options dialog box. 16.8 CANON CLC500 with EFI Fiery RIP ------------------------------------ This is a proprietary driver developed by EFI. Choosing the Halftone By Printer option in the Print/Options dialog box does not effect the output. The Halftone by PhotoStyler option does work, but the output is noticeably slower.
