Custom ink profile
I have Epson Stylus Pro 9890 with a damaged print head, the cyan ink channel is not working. We want to customize the ink channels in the printer driver together with calibrated ICC profiles. The Cyan ink channel is not working and we need to ignore that channel and the light cyan channel will be replaced by cyan. We trying to avoid using a RIP software. So how can one change the ink channel colours in the printer driver?
