A few days ago I installed a set of Neutral K7 inks in a new and very sparingly used Epson3880 printer (about 5 pages of color prints). With phone support I got the printer to print correctly. My system is a Mac running OS10.10.5, QuadtoneRIP version 2.7.6 and I print using Printtool v.1.1.0
The printer was flushed using Piezoflush 3 cycles for each of the black inks. Since I’m using a Mac, I don’t think there’s a utility to perform an initial fill cycle.
After the K7 inks were installed I did a nozzle check and it all seemed good.
Now, when I printed a b&w (grayscale, graygamma2.2)image on Hahnemuhle PhotoRag I noticed there to be a mild color cast in the highlights and lighter midtone areas. The cast looked a little yellowish or may be light selenium. I did another Powerclean (matte black ink was the active cartridge), and that didn’t seem to make a difference.
Is there something I can do to eliminate the cast.
Attached is an image of the test print. The image files were were a b&w test image from inkjetmall.com (proofofpiezography-21.tif) and another from NorthlightImages.
I also printed the same images on an Epson7900 printer using ABW mode, I don’t see a cast on that print.
