Epson R1800 B&W printing

From: Joe on 22 Jan 2010 18:21 Epson R1800 B&W printing. When printing colour the printer is near screen accurate for the print. Yet when a conversion to B&W through Photoshop there is a green cast and even with full amount of magenta dialed in still shows a cast even to the point a magenta cast comes through. My suggestion has been to do a head alignment. Whats the best way of correcting this cast as it just can't be dialing in colours. Thanks

Did you convert to greyscale? Or is it a desat. RGB? Head aligning would seem to be an odd suggestion for a color cast. -- john mcwilliams

Kinda what I suspected. Try converting one to grey scale, then see if you rid yourself of the color cast. Using Epson inks? -- john mcwilliams
