Types of CMRs
Different situations call for different types of CMRs. Some CMRs are created by
product manufacturers so you can download and use them, while others are
created by your printer or other color management software. If you have the
appropriate information, you can also create CMRs yourself.
Some CMRs are used to interpret input files (similar to the function performed by
ICC input profiles), while others are used to prepare the final print job output for a
specific printer (similar to the function performed by ICC output profiles).
Color conversion CMRs:
Color conversion (CC) CMRs are used to convert colors to and from the ICC
profile connection space (PCS), a device-independent color space. You can use
them to prepare images for color or grayscale printing.
Color conversion CMRs are an essential element of any AFP color management
system because they are ICC profiles encapsulated in AFP structures. The AFP
structures add information that your color management system can use, but it
leaves the ICC profile unaltered.
You can use color conversion CMRs to produce consistent colors on different
devices. In a color system, they help ensure that the colors on your monitor are as
close as possible to those that are printed. If you move the print job to a different
printer, the colors are adjusted again to match the new printer.
In a grayscale system, color conversion CMRs map colors to appropriate shades of
gray to produce high-quality black and white images.

Note: CMRs can vary in size from several hundred bytes to several megabytes.
If your print job uses relatively few CMRs, including them in the print file might
not have an impact on the performance of your system. However, if your print
job uses more than 10 CMRs, the size of the print job can increase so much that
file transfer rates and network traffic are affected.
include them in every print job.
You can configure all your print servers so they can access the CMRs.
resource search path on the print server.
To store CMRs in a central resource library, you must install them by using an
application such as AFP Resource Installer.
access tables (RATs).
AFP Resource Installer creates the RAT when CMRs and data objects are
installed. We recommend that CMRs and data objects be installed in separate
resource libraries and that you store resources that do not require RATs (such as
form definitions, page definitions, and overlays) in other resource libraries.
and you can use the names in the print data stream.
These names are created when you install the CMR by using AFP Resource
Installer and are UTF-16BE encoded.
