Adjust CMYK curves for a media family

PRISMAsync Print Server offers a CMYK editor with a pixel-precise preview to adjust the color density for specific media. You can emphasize colors or other elements for images printed on media that belong to a media family. The new CMYK curves are added to the media family calibration values.

There are two modes to edit the CMYK values of a media family:

  1. Basic mode, for simple CMYK editing with sliders for quick and easy color tweaking.

Be aware that the CMYK adjustments affect all media of the media family.
