- SCANNER SUPPORT
- Adobe Photoshop supports all scanners that are 100-percent compatible with
- the TWAIN specification for image acquisition. In addition, some scanner
- manufacturers provide acquisition plug-in modules that interface directly
- with Adobe Photoshop via the Photoshop(TM) plug-in specification. For
- information on setting up your scanner to work with Adobe Photoshop, see the
- user guide and your scanner documentation. If your scanner manufacturer did
- not include a TWAIN source module or an Adobe Photoshop direct plug-in
- module, contact the manufacturer directly. Following is a list of
- manufacturer customer service numbers:

- Howtek 603-882-5200
- Microtek 800-654-4160
- Kodak 800-445-6325

- AVR 800-544-6243
- Logitech 510-795-8100 (US and Canada)
- ++41 (0)21-869-9851 (Europe)
-
- If your scanner doesn't work with Adobe Photoshop, please contact the
- scanner manufacturer to get the latest firmware and/or the latest driver
- for your scanner.
-
- There is a problem with the Mustek hand-held scanners and small amounts of
- conventional memory. If you have less than 400Kb of conventional memory
- available prior to starting Windows, the Mustek scanners will report an
- "Out of Memory" error. To alleviate this problem, remove some of the device
- drivers and/or TSRs (Terminate and Stay Resident programs) from memory by
- editing your config.sys file. Refer to your DOS manual on how to do this.
-
- ABOUT THE JPEG MODULES
- The JPEG modules in Adobe Photoshop require that the system have at least two
- megabytes of virtual memory. The virtual memory can be provided either by a
- temporary or permanent swap file in this case, but as discussed above,
- permanent is recommended.
-
- On systems with large amounts of memory (64Mb or more of RAM), the JPEG
- Modules may fail to load due to a bug in the Watcom 386 compiler. Lowering
- the amount of memory allocated to Adobe Photoshop (use the Memory...
- in the File/Preferences sub menu) should alleviate the problem.
-
- ABOUT PATHS
- Adobe Photoshop 2.5.1 now supports Tiff 6.0 previews for its EPS files.
- This allows clipping paths to become visible when placing an EPS file in
- software supporting the Tiff 6.0 previews for EPS files. There have been
- implementation problems in some software that show the clipping paths with
- a non-transparent mask. If you experience this problem, please call your
- software's Technical Support.
-
- USING PRESSURE-SENSITIVE TABLETS
- Adobe Photoshop supports only pressure-sensitive digitizing tablets that
- are 100-percent compatible with the Microsoft« Pen Windows specification.
- For more information about compatibility, please contact the vendor of your
- tablet at:
-
- Vendor Customer Service Number:
- ---------- ------------------------
- Wacom Technology Corporation: 800-922-6613
- Kurta Corporation: 602-276-5533
- CalComp: 800-458-5888
-
- ABOUT VIDEO COLORS
- While you can use Photoshop with video cards that support only 16 colors,
- it is highly recommended that you chose a video board that supports at least
- 256 colors. For the best results, a video board that supports 24-bit color
- is recommended.
-
- ABOUT CMYK SEPARATIONS
- When using printers that support Adobe PostScript Level-2 software, the
- printer itself has the ability to do CMYK separations. Normally, Adobe
- Photoshop does the CMYK separations. If you want the printer to do the
- CMYK separations rather than Adobe Photoshop, you must disable the CMYK
- separations option.
-
- If your printer's PostScript Level-2 software supports an internal method of
- color separating, you may choose to disable the Adobe Photoshop software's
- CMYK separations by doing the following:
- 1. Open the PHOTOSHP.INI file located in your WINDOWS directory.
- 2. In the [Adobe Photoshop] section of the PHOTOSHP.INI file, add the
- following line with no spaces and capitalization exactly as shown:
-
- DISABLERGBTAGS=1
-
- 3. Save the PHOTOSHP.INI file and restart Photoshop to see the change.
-
- ABOUT VIRTUAL MEMORY COMPRESSION
- By default, Adobe Photoshop uses virtual memory compression when swapping
- image data to disk. This feature allow Adobe Photoshop to use less disk
- space but there is a tradeoff in performance. Disabling this feature will
- cause Adobe Photoshop to use more disk space but to have better overall
- performance.
-
- To disable virtual memory compression option:
- 1. Open the PHOTOSHP.INI file located in your WINDOWS directory.
- 2. In the [Adobe Photoshop] section of the PHOTOSHP.INI file, add the
- following line with no spaces and capitalization exactly as shown:
-
- DISABLEVMCOMPRESSION=1
-
- 3. Save the PHOTOSHP.INI file and restart Photoshop to see the change.
-
- VIDEO DRIVER INCOMPATIBILITIES
- If you are experiencing problems with the way your images look, please refer
- to the Troubleshooting section in the Getting Started Guide. Please be sure
- you have the most up-to-date drivers before reporting problems to Adobe's
- Technical Support. You can contact your video card manufacturer for
- information on how to receive the most recent driver. The following are a
- list of video cards that are known to have incompatibilities with Adobe
- Photoshop.
-
- - Video cards that are based on the Weitek P9000 video chip set have shown
- problems when using the marquee or cropping tools. To work around this
- problem, make the selection and then force a screen redraw (close and
- open the window or zoom in and then out).
-
- - When using the Prodesigner II card in 256 color mode, there are problems
- when using Indexed Color mode. There are also problems in most modes when
- blending from black to white.
-
- - The 9GXi and 9GXe cards are known to be incompatible with Adobe Photoshop.
- If you are experiencing problems using either of these cards, get the most
- up-to-date drivers and try again. If the problems persist, you may need to
- use a different video card in your system.
-
- - The Orchid Fahrenheit 1280 & VLB sometimes experience problems when
- displaying Pantone«* colors in some video modes. If you experience
- problems, update your drivers and/or try a different video mode to see
- if the problem is resolved. The VLB may also have problems with the
- redrawing of the brushes palette when Adobe Photoshop initially starts up.
-
- PRINTER DRIVER INCOMPATIBILITIES
- Some printer drivers, most specifically the unidrv.dll driver, can
- occasionally cause Adobe Photoshop to crash when printing bitmap images on
- HP« printers. If you are having difficulties printing to HP printers, try
- converting the image to grayscale first and then printing it.
-
- DISK COMPRESSION SOFTWARE INCOMPATIBILITIES
- It is recommended that you assign Adobe Photoshop scratch disks to an
- uncompressed disk. There are incompatibilities between the Adobe Photoshop
- virtual memory and compressed disks. If you encounter problems using Adobe
- Photoshop when the program or scratch disks are on a compressed disk,
- then move the program and/or assign the scratch disk to an uncompressed
- disk.
