15 Spot Color Simulation
ORIS Press Matcher⁄⁄Web allows you to correct spot colors using a
separate color table called spot color correction file (*.SCG). The CMYK
values defined in these files are calculated from the device-independent
Lab values and the data characterizing your printer (RFP file, ICC profile
or measurements).
Using SCG files provides the following benefits:
• All spot colors located within the printer’s color gamut are simulated
very precisely.
• Spot color simulations can be optimized without adversely affecting
process colors, because a separate color table is used.
If no SCG file is used, the CMYK equivalence values are corrected. They
are corrected in the same way as process colors, e.g. using the
ORIS_DAT color table.
Creating Spot Color Correction Files
The spot color names and Lab values can be imported from spot color
libraries (*.lab), ColorPicker files (*.LCP) and color exchange format
files (*.CXF). You can also define your own spot colors, either by measurement
or by entering the values manually.
Various spot color libraries for PANTONE® 1 and HKS colors are available
in the ORIS Press Matcher⁄⁄Web installation directory.
Refer to page 15-5 for detailed instructions.
