My Kyocera FS-C5400DN colour laser printer prints some documents that include graphics (greytone or coloured) blured
A pure textpage is perfect and most time colourpages are fine too. It looks if black would be overprinted with CMY and CMY would not have some offset.
Are there known settings in
cups, or in a hidden printer menu that would improve this?
Do the files need a kind of preparation to tell the printer about colour ranges?
Here is a screenshot of the first cups configuration menu. I do not know what Trapping and Halftone will exactly do. But i guess halftone will reduce the number of different colours. Will Trapping help?
