Appendix A: About Printer Tables
A-2
Standard Tables
Each printer table is named according to its correction
formula. There are 45 standard RGB tables and 25
standard CMYK tables. The standard printer tables
consist of combinations from one of the available gamma
correction values (1.0, 1.2, 1.4, 1.6, 1.8, 2.0, 2.2, 2.5, 2.8)
and one of the available black level values (-40, -30, -20,
-10, 0). For example, the printer table SG16BN30 has a
gamma correction value of 1.6 and a black level value
of -30.
The standard tables are all set for a hue shift of 0°, a
saturation level of 100%, and an automatic contrast
calculation.
The default table for the export module is gamma 2.0,
black level -20. Choosing a black level of -10 or 0 lightens
a print and helps to bring out details in and shadow
areas. A black level of -30 or -40 darkens a print.
Custom RGB Windows Tables
Four custom tables are included with the Windows
version of the export module.
SLINEAR.TBL—does not modify the digital color data it
receives from the application. It outputs the same values
it receives, which allows you to use calibrated digital color
data directly from a color calibration program.
SLEMON.TBL—includes a color matrix that modifies the
yellow digital image data it receives. These modified
values produce a lighter shade of yellow, which is better
suited for graphic arts applications.
SPHOTOCD.TBL—obtains maximum image quality from
Photo CD images that were opened using the RGB video
metric.
SDEFAULT.TBL—uses the same correction values as
the XLS Default selection and the SG20BN20.TBL printer
table.
