I used PiezoFlush in all cartridge slots for the second time today. I’ll install the Neutral K7 cartridges tomorrow and see if that has resolved the problem.
When I don’t need to tone the image I’ve gotten good results with Epson’s ABW mode on my 3880 and 9900 printers. Like you, and grudgingly, when I need to tone an image I resort to leaving the image as RGB and print them. I was hoping to find a good solution with the Neutral K7 inks and it’s been rather frustrating. I prefer not switch papers with cooler tones to neutralize the cast.
[QUOTE=Mack;9059]I found much the same with the yellow, and some residual magenta too when I put the K7 into a 3880. The tint didn’t leave until the second batch of inks were installed, and even now I sometimes will get a tint of yellow that is objectionable. That is one creepy color to get rid of. However, some of it can be altered by switching the paper to a cooler or one with optical brightners to add a bluish tint (Which is another can of worms with longevity.).
I went to the K7 Selenium over the Neutral K7 as I prefer a cooler tint than the yellow I saw in the Mall’s website images. Still, it is often too yellowish for me over what I used to get with my old Kodak Selenium chemical baths which had a bit of purplish tint. Guess I’ll have to live with it now, or figure out a way to add some tint to the K7 Selenium inks. Seems to be more of an issue with the lighter to mid-tones much as you found. In the Dmax blacks, it’s hard to tell.
Sadly, I now find when I do B&W I resort to leaving the image in Adobe 1998 RGB and printing it on the color pigment printer as I can control the tint of the B&W on that printer to what I want. I can add a bit of cooler tint in the lighter curves layers of the RGB image and be done with it rather than a fixed and locked tint of the K7. Changing papers isn’t as much of a problem either as I can re-tint with the pigment and the image’s curves. Funny how a little added color like yellow can throw an image off.
I do like the Gloss Optimizer of the K7 and wish Epson had that choice rather than the wasteful MK/PK black ink switch. My PK is now blocked for some reason on a recent changeover. Yay Epson! :o(
Good luck though.
