ColorThink Device Link Tip
From ColorWiki
Device link profiles are direct connections between two device spaces. As such, they don’t have a “gamut” and cannot be graphed in a 3D grapher like the one in ColorThink. However, you can see the results of using a device link profile in a workflow, and you can graph the behavior of a device link profile in the Grapher.
First off, note that device links start and end with device spaces. For example, a CMYK to CMYK device link will have to start with CMYK values and will deliver CMYK values at the end. This device link cannot be placed in a workflow immediately after a transition that ends in Lab or RGB for example. Some people try to use a device link in the wrong place and think there is something wrong when it does not work.
Here is an example of how to use a CMYK to CMYK device link in a workflow, and view the results in the Grapher:
- Open a Worksheet
- Click the add (+) button and browse to Favorites > Stunt Files > Lab cloud
- Add a CMYK profile to the workflow to create CMYK data
- Add a CMYK device link profile
- Turn on delta E
- Move the delta E arrows so that the CMYK profile is compared with the Device Link profile (see illustration).
- This presents a comparison between the CMYK profile and the device link.
- Under the delta E results image, click the untitled list drop down box and choose Graph list.
- The Grapher will show you the vectors representing the difference between the CMYK profile and the action of the device link profile.
This is just a primer on the use of device links in ColorThink. You will want to adjust these procedures according to how you use device links in your own workflow.
