Thanks guys, appreciate your help!
@Garnick & Mark
I had this idea already (as I had corrupted ICC profiles before). So I already replaced the ICC profiles for my four different papers from Tecco without any change.
@ Mark
The principle of CM is clear, but what I don't understand, if it is a software issue on my Mac, you only the Epson 9890 shows the tint and not also the 3880 on which I print with the same papers and generic ICC profiles from Tecco?
So here is a list of everything that changed since my latest correct print on the Epson 9890:
- Lightroom/Photoshop Update (I already tried printing with Lightroom and Photoshop. Same tint from both apps at the 9890)
- I build in a LED strip to my 9890. Actually this is just for fun and as I don't have a spectra viewer the LED strip should not influence the printer. To be sure, I also printed a test with the LED light unplugged from electricity to ensure that there is no fancy influence to the print head or electronic. (see attached some pictures of the LED)
Here is my system configuration:
MacPro late 2014 with OSX 10.11.4 (did not update to the latest version yet)
Latest versions of Lightroom and Photoshop
My whole printing workflow is based on Lightroom using presets for all kind of paper sizes from the rollpaper.
My test file I printed was a b/w converted RAW file (not JPEG or tif) right out of Lightroom.
Tomorrow I will try to create a custom ICC with my ColorMunki. I know the ColorMunki isn't that advanced than the i1 Pro, but definitely better then nothing.
I'm also gonna try printing from my MacBookAir to ensure it is not an issue of my MacPro.
