well if you get a ten channel printer (which one?) you can remap one of the colour to yellow in quadtonerip and make use of the yellow ink.
all oyu have to do is lie to the printer. in the older models you just had to swap the cartridge chip and reset it or switch to a refillable cartridge where you put the ink you need.
Can anyone tell me if I can print quadtone images using my ten channel epson 24" printer with one dead yellow channel. I tend to print everything in Neutral tone. Many thanks, in advance. /ray
