difference in QTRip iPC/Mac OSx


I don’t know, but it seems the ripping with PrintTool in my Mac OSx has a higher qualtity compared QTRRip in my PC.

When I run only PC (before PDN) it looked like dots were missing occasional. My first reaction was clogged nozzels, I tried to do cleaning but this didn’t show any difference. The problem was minor but still you could see it. In gumbichromate process this was not any real issue, but maybe in Pd and carbon printing it could be.

When I switched to the PDN system I also switched computer to a iMac this phenomena could not be seen.

Still I’m not sure if this is real or if this is an illusion. So, that’s why I’m asking you if this has been anyone else?






The qtrGUI program pre-rips the data before sending it to the printer. It may very well be ripping the pixels using a different algorithm and PPI than the Mac.
