I am attempting to print a desaturated RGB image (it appears to be greyscale but is RBG) on an HP 4000 imageplotter. No matter what adjustments I make, it appears reddish…more like a strong sepia tone. When I print the exact same image on my Epson 2200, it is a terrific print with rich blacks and a full range of grey tones. Anyone else experienced this problem? Did you find a work-around?
Hello,
While I can’t say for sure, what an HP 4000 does as far as printing black-and-white. I do know that the Epson’s use all four colors plus blacks to produce a black-and-white image, will in the case of my 4000, all six colors and two shades of black.
I don’t know whether you have your workflow set up with various ICC profiles for each printer, paper and ink that you use, in combinations there of. But you do need them. I fought with my Epson Stylus Pro 4000 for awhile trying to get a decent black-and-white print on the thing. Once I profiled my scanner, my monitor, my papers that I use, I mean the whole nine yards. I started getting some very decent black-and-white prints.
So I would guess that you need to get some sort of profiling software and profile the whole system, including each combination of paper and ink crossed all your printers. Printing colors on most printers is relatively easy printing black-and-white is much more difficult to do without getting color casts. Until I profiled my whole system I tended to get green color casts. When printing black-and-white pictures.
So that’s what I have for you in the for what it’s worth column.
