(3) With the ICC profile selected, RGB data from the application software are converted
into CMYK data. The ICC profile is downloaded into the RAM of the PS-7000 by
the PS driver.
(4) With the CRD selected, RGB data from the application software are converted into
CMYK data. The CRD is already installed in the ROM of the PS-7000.
(5) CMYK colors can be adjusted, using the PLEX Color Filter, if necessary.
2.3. Amount of ink used
In printing with CMYK data, without use of CRD or ICC profile, blur or discoloration may
occur due to excess amount of ink put on printout. This kind of problem can be solved by
reducing the ink amount through the CMYK adjustment function of the application
software. The maximum amount of ink recommended for each type of printing media is
listed below for your reference.
- Glossy paper / Glossy film: 240%
- Semi-glossy paper: 240%
- Heavy coated paper: 260%
