So, Source and Destination mirror a logical two-step process most Color
Management Systems use to translate images between device color spaces;
• The Source Profile brings the image into the PCS
• The Destination Profile connects the image from the PCS to the output
device, such as a Monitor, Printer, or Proofer.
However, this is not the case with a Kodak CMS.
Kodak has patented its composition technology. This technology takes the
Source and Destination Profiles and composes them into a single color
transforming profile.
This technology adds significant improvement in the quality and performance of
the Color Management System.
Note: : : : : You use the Source/Destination information when you setup or use your
CMS-based application, such as PageMaker 6.5.
