2.1. Overview
As color conversion tables, the PS-7000 has been provided with the dedicated CRD (Color
Rendering Dictionary) and ICC (International Color Consortium) profile. In addition,
the PLEX Color Filter contained in the accessory utilities will offer easy color matching
without changing the original data.

software, such as Adobe Photoshop, into CMYK (Cyan, Magenta, Yellow, Black).
