=========================================================
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.
