Managing color on the GA-1121

If you are printing with the PostScript driver from a Windows computer and have Two-Way Communication enabled, the name of each downloaded or custom profile is represented in the CMYK Simulation Profile setting menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as Simulation-1 through Simulation-10. For more information on Two-Way Communication, see the User Software Installation Guide.

The None setting sends your original CMYK data to the copier/printer in its calibrated state, without conversions to simulate another printer.

The CMYK Simulation Profile setting you specify depends on the press standard for which the CMYK data was separated.

•For images that were separated using a custom separation (such as a separation produced with an ICC profile), choose the corresponding profile on the GA-1121 with the CMYK Simulation Profile setting.

•For images that were separated for SWOP, choose SWOP as the CMYK Simulation Profile setting.

NOTE: To properly simulate a printed image that was separated through the use of an ICC profile, the same profile must be present on the GA-1121. For more information about downloading ICC profiles to the GA-1121, see “Downloading profiles” on page 3-4.

NOTE: This feature is not available with the PCL driver.

CMYK Simulation Method

The CMYK Simulation Method allows you to define your preferred CMYK-to-CMYK conversion technique.

•Quick applies one-dimensional transfer curves to adjust output densities in the cyan, magenta, yellow, and black channels. This technique leads to pleasant color output from your copier/printer because pure primary colors are not “contaminated” by other colorants. While it is the fastest simulation method and perfect for drafts, avoid using it for final documents that will be used as press proofs. Other techniques offer more color simulation accuracy, which is expected by proofing applications.
