Adjust CMYK curves of 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.

  2. Advanced mode, for precise CMYK editing.

IMPORTANT

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