My computer is a Mac Pro running Yosemite 10.10.5, the imaging software is Photoshop CS5. I’m printing from Photoshop using Epson’s ICC profiles, soft proofing in PS. Computer monitor is a 30" Apple Cinema Display. It’s been calibrated with an Xrite system - that’s a little old but seems to have been doing a good job. My printer is an Epson 4900 and the paper is Epson Cold Press Bright Textured Matte. I’ve printed literally hundreds of images with this combination - Epson Inks. My system has pretty much been WYSIWYG until yesterday.
I recently started replacing my Epson Inks with Cone Color Pro Inks. To date I’ve replaced the LLK, VLM, Y, and LK carts and inks. Had seen some wierdness in the cart replacement as I had some of the old battery type chips - problem solved by replacing the chips with the newer non-battery type. Many thanks to this forum for the threads which helped me figure that one out As of yesterday though, ALL my prints are displaying a dramatic shift towards magenta. Getting blues correct has become an impossible task. It’s almost as if the Epson magenta in the line has worked through and now I’m seeing the Cone Colro Pro Magenta? I understood there weren’t any issues replacing Epson Inks with Cone Color Ink with respect to color.
I’ve done several nozzle checks which appear normal, no skipping and all the right color inks in the right places. Did a power cleaning as well. There doesn’t appear to ba any clogs anywhere in the system.
I’m at a loss as to why this sudden color shift. It seems to have started over the course of one or two prints.
Happy to provide any additional information needed to help solve the problem. Thanks!
