Remapping Colors for Imported CMX Files
PANTONE colors present in the CorelDRAW file that are less than 100% density, do map
through the gspcmap.ink. If OMEGA finds the tint color in gspanton.pal, it is converted to a
CMYK color, but loses the PANTONE color name.
RGB
CorelDRAW files created using RGB colors are converted into Gerber's WCS (Working Color
Space). In the WCS, the CorelDRAW RGB is mapped to Gerber RGB, which is then converted to
CMYK based on the selected Gerber output device.
CMYK
CMYK colors in the 0-100 range are mapped directly from CorelDRAW into Composer. The
CMYK (0-100) value that you specify in CorelDRAW will be the same CMYK color in
Composer. CMYK (0-255) values from CorelDRAW are converted to CMYK (0-100) color model
in Composer, which can cause color inconsistency. To ensure uniform colors, use the CMYK (0-
100) color model when creating files in CorelDRAW.
How to remap colors when importing CMX files
Note: It is important that you have set up Color Management for your system. See the
Practical Hands-on Color Management for quick and easy steps to configure Color
Management for your workflow.
Whenever a CMX file is imported, OMEGA appends a running text file named gspcmap.txt.
This file is located in GSP > Software > Palettes. Each time a CMX file is imported, the most
recent CMX file name, and all the colors included in that file are appended at the end of the
gspcmap.txt file. To import fill and stroke colors, the CMX file converter uses a mapping file
located in the Palettes folder called gspcmap.ink. The gspcmap.ink file is a user-created text file
that can be edited with the Notepad or WordPad applications. You may create and edit the
gspcmap.ink file to alter how a color is mapped in OMEGA. You can specify specific CMYK
colors, Gerber Spot colors, GerberColor Spectratone colors, and PANTONE Simulations. The
.ink file provides a way to alter how specific colors convert, for example adjusting a color to
match a logo. Image files embedded in a CMX file are not affected by the color adjustments in
gspcmap.ink.
To remap colors when importing CMX files
1
Export a CMX file from CorelDRAW.
2
Import the CMX file into Composer.
3
Navigate to GSP > Software > Palettes and open the gspcmap.txt file using Notepad or
WordPad.
4
Go to the end of the gspcmap.txt file and locate the CMX file that was just imported.
5
Locate the lines with CMYK, RGB, or PANTONE colors within CorelDRAW software
that need to be revised.
6
Edit the second half of the line (0 0 0 0) by replacing the zeros with a new color value
using the following conventions:
