I'm Putting this here as apposed to the rip software area because it is uniquely different the Screen print color separation mechanical film rip software. I currently run the latest Print Por Special edition for DTG.
This software has some unique setting for doing CMYK on various colors and I am experimenting with altering the setting to both save ink and increase image quality. Sadly the special edition, while having many more controls is rather archaic to learn and understand.
