- What are ColorSync(TM) 2.0 Plug-In Modules?
-
- The ColorSync(TM) 2.0 Plug-In Modules provide an easy way
- for you to obtain high quality reproduction of color images.
- Together with the ColorSync(TM) 2.0 System Extension and the
- installed device profiles, the ColorSync(TM) 2.0 Plug-In
- Modules ensure that your color images will be reproduced
- most accurately on any device. Three Modules (Acquire,
- Export, and Filter) are available to fit into any type of
- work-flow, and to provide color matching capabilities to the
- novice color user as well as to the most demanding color
- user.
-
- With the Plug-In's you will be able to:
- * Accurately print the image viewed on your monitor.
- * Accurately print or view the image you have scanned.
- * Embed a profile in your image to be specified as the
- image's source.
- * Make color separations for any press printing condition.
- * Use your in-house device to preview what your image will
- look like on the printing press.
- * Execute any custom color matching needed.
-
-
- What are the system requirements?
-
- Before using any of the modules, you should make sure that:
- * Your Macintosh has a 68020 or later processor, or a
- PowerPC 601 or later processor.

- other software that accepts version 4.0 Photoshop Plug-In
- modules.
-
-
- How do I install the software?
-
- If ColorSync(TM) 2.0 is not already installed on your
- system, you can download a copy of the ColorSync(TM)
- installer disks from any of the on-line services mentioned
- at the end of this document. Please follow the instructions
- that are included on the disk before installing
- ColorSync(TM) 2.0.
-
- The ColorSync(TM) 2.0 Plug-In Modules are installed by
- coping all three into the "Aquire Export" folder in your

-
- Important Definitions
-
- Color matching/color reproduction:
- The process of making a controlled transformation of color
- values generated from one device to values intended for
- another device.
-
- Profile:
- A file containing information about the color reproduction
- capabilities of a device, such as a scanner, a digital
- camera, a monitor , or a printer. Commonly, two profiles
- (source and output) are used during a color matching
- session.
-
- Source profile:
- A profile representing a device from which an image was
- originated. For example, if an image is scanned in, then the
- scanner profile is the source profile. Or, if an image is
- created and viewed on the monitor, then the monitor profile
- is the source profile.
-
- Output profile:
- A profile representing a device on which an image is to be
- outputted. For example, if an image is to be printed on a
- color printer, then the printer's profile is the output
- profile. Or, if an image is to be viewed on the monitor, the
- monitor profile is the output profile.
-
- Proofer profile:
- Proofing is the process of using one device to predict the
- output of an image on another device. A proofer profile
- represents the device which is used for the prediction. For
- example, if an image whose output on a color printer is to
- be proofed on a monitor, the monitor profile will be the
- proofer profile.
-
- Matching style:
- Because of the differences among devices' color capability,
- different methods exist for applying color matching on an
- image. The matching style is usually selected according to
- the content of the image . See below.
-
- Perceptual matching style:
- A matching style which gives the most pleasing reproduction
- given the capabilities of the devices involved. This is the
- most commonly used style, especially for reproduction of
- photographic images.
-
- Colorimetric matching style:
- A matching style where colors are reproduced exactly the
- same as the eye can distinguish. This may result in clipping
- of certain colors which can not be reproduced on a device.
- Colorimetric matching can further be divided into relative
- colorimetric matching and absolute colorimetric matching,
- where relative matching accounts for the ability of the
- human eye to automatically adapt to the surround white
- (e.g., white of the paper the image is printed on), and
- absolute does not. Colorimetric matching is most commonly
- used for reproducing Logo colors where the exactness of the
- color is important.
-
- Saturation matching style:
- A matching style where the vividness of the image is best
- preserved. This style is mostly used for reproduction of
- graphs and pie charts.
-
- Matching quality:
- The matching quality indicates the overall computation
- precision of a particular matching session. Higher
- computation precision requires more run-time memory. It is
- always best to use the highest matching quality your system
- allows.
-
-
- Using the Acquire Module:
-
- The Acquire Module will import a Tiff image from disk into
- Photoshop while applying ColorSync(TM) matching. The Acquire
- Module is most convenient to use if you simply want to match
- your image for printing from Photoshop, or if you want to
- match an image you scanned previously for viewing.
-
- To use the Acquire Module:
-
- 1. In Photoshop, select the "Tiff with ColorSync(TM)
- Profile..." from the "Acquire" menu under "File". A standard
- file selection dialog box appears prompting you to select a
- Tiff image to be imported.
-
- 2. Select the Tiff image you want to import and click the
- "Open" button. The ColorSync(TM) Acquire Module dialog box
- appears. Select the appropriate "Source" and "Output
- Profile" for the image, and select the desired "Matching
- Style" and "Quality" setting. Refer to the "Important
- Definitions" section above for more explanations .
-
- 3. Click the "Import" button to start importing.
-
- Note 1: If the Tiff image to be imported already has a
- profile embedded, the embedded profile will show up on the
- list of available Source Profiles as an Italic item.
-
- Note 2: Only profiles whose color space information match
- that of the selected Tiff image appear in the list of
- "Source Profiles". Therefore, for a Tiff CMYK image, only
- profiles that are CMYK based are available as "Source
- Profile".
-
- Note 3: Certain Tiff images cannot be imported if they
- contain unsupported Tiff image format features such as
- compression.
-
-
- Using the Filter Module:
-
- The Filter Module will apply ColorSync(TM) matching on the
- current Photoshop image. The Filter Module is most
- convenient for matching an image which is already in
- Photoshop without writing it to disk.
-
- To use the Filter Module:
-
- 1. In Photoshop, select the "ColorSync(TM) Filter" in the
- "Color Matching" menu under "Filter". The ColorSync(TM)
- Filter Module dialog box will appear.
-
- 2. Select the appropriate "Source" and "Output Profile" for
- the image, and select the desired "Matching Style" and
- "Quality" setting. Refer to the "Important Definitions"
- section above for more explanations.
-
- 3. Click the "OK" button to start filtering.
-
- Note: Due to limitations of the Photoshop Filter Module API,
- the ColorSync(TM) Filter Module can only match images
- from/to the same color space. Therefore, it cannot match an
- RGB image for a CMYK device, and vice versa.
-
-
- Using the Export Module:
-
- The Export Module will save the current Photoshop image to
- disk as a Tiff image with ColorSync(TM) matching applied. It
- is the most flexible module out of the three.
-
- To use the Export Module:
-
- 1. In Photoshop, select the "Tiff with ColorSync(TM)
- Profile..." module from the "Export" menu under "File". The
- ColorSync(TM) Export Module dialog box will appear.
-
- 2. Select the desired choice from "Processing Selection".
- Action for each of the choices are as follows:
-
- * "Embed" simply embeds into the current image the
- selected "Source Profile" with the selected "Matching
- Style". No color matching occurs.
-
- * "Match" applies a matching session using the selected
- "Source" and "Output Profile" and the selected "Quality" and
- "Matching Style". The "Output Profile" is also embedded in
- the output image to indicate that the matched image is now
- intended for the device associated with the profile.
-
- * "Proof Matched" applies a proofing session using the
- selected "Source", "Output", and "Proofer Profile" and the
- selected "Quality" and "Matching Style". "Matching Style" is
- applied separately for the source-to-output match AND for
- the output-to-proof match. The "Proofer Profile" is also
- embedded to indicate that the matched image is now intended
- for the device associated with the profile.
-
- * "Custom" enables more extensive matching sessions.
-
- Click the "Export" button if "Embed", "Match", or "Proof" is
- selected and go to step 6. Click the "Select..." button if
- "Custom" is selected and go to step 3 below.
-
- 3. "Custom" matching is used for the rare occasion when you
- want to perform matching with many profiles. It comes up
- with a dialog box with a scrollable list of "Profiles
- Selected" and a "Quality" selection that is to be applied
- for the entire matching session.
-
- 4. Click the "Add Profile" button to add a profile after the
- last element on the "Profiles Selected" list. This brings up
- the list of available profiles. Select the desired profile
- and the "Matching Style" setting and click the "Add" button.
- The "Matching Style" selecting is applied for the match from
- the current profile to the next selected profile. The
- "Matching Style" of the last selected profile is ignored.
-
- 5. Repeat step 4. as many times as necessary to add more
- profiles to the list. When done, click the "Export Tiff..."
- button. To remove a profile from the list, all succeeding
- profiles following that profile must be removed first. To
- remove the last profile from the list, simply select the
- profile and click "Remove Profile".
-
- 6. The standard save file dialog box will appear prompting
- for a name of the image file to be saved as. Enter the
- desired file name and click the "Save" button to execute.
-
- Note: An image must be loaded in RGB or CMYK mode in order
- for the "Tiff with Color Sync Profile" menu item in the
- Export menu item to be selectable. The item is not
- selectable if the image is in indexed mode.
