Just in case someone has the same problem in the future: gutenprint has 9 dithering algorithms and some of my problems were probably related to using defaults values. EvenTone or Hyblid EvenTone are the best for photography. From the documentation:
- EvenTone This relatively new algorithm...
I tried to use an old cartridge as a cleaning cartridge (motorbike insect remover + isopropyl as anti-foaming agent), but my printer didn't want to recognise the cartridge. So I decided to use the "soak the pad" method on half of the pad and i hope gravity will drain the cleaning solution slowly...
/necro bump, but I'm wiser now/
In my case it was probably an early indication of waste ink line being clogged. So overpressure was pushing the ink back in the print head.
Overcast sky, white balance corrected. My print shows green tint and strong blue. Is that something that can be corrected with colour profile or I should keep exploring the settings and gutenprint manual?
It's a bit more complicated. From gutenprint manual about Color Model:
"-RGB Color Send RGB (red/green/blue) data to Gutenprint. This is the normal choice when printing in color. While most color printers are actually CMYK devices, it is normally best to send RGB color to Gutenprint to allow...
I'm ~20 test prints later and the best results without any colour profile I'm getting with... CMYK colour model and Four Color Standard Ink type. When I use RGB colour model I get disastrous blue/green gradient and red is pink.
Please do not asses the quality - it's cheapest available paper and...
Really good article about cleaning chemicals [1]. I'm using some motorbike insect remover containing only some surface active substances right now.

The next step was to soak rest pad in cleaning fluid and leave it over night. Somehow I missed that if there is no air gap between the print head and the cleaning fluid in the pad the gravity might drain my cartridges. And that's exactly what has happened: I woke up to 6 out of 8 cartridges...
I'm cleaning the print head using stripe of wet sponge placed under the head and running it manually back and forth. The cartridges are in place - should I remove them? It looks like ink is flowing down to the sponge. I can't easily remove the head, so this is the only method for me.
Edit...
Thank you very much - plenty of information!
I don't have any profile made for my printer yet - I was using profiles provided by Marrutt for their ink and paper type. There are at least 2 drivers from Epson - one is useless, the other looks better, but it's too early for me to tell if it's any...
OK, it's all relatively new for me, so Il appreciate all comments, advices and points of view :)
Epson supports linux - I'm testing the official driver right now :) More info tomorrow.
P.S. Linux used to be for geeks, but it's not the case anymore in most cases.
Thanks for the replies, and please do not judge my setup by this print :-) Win/mac are not options for me - I use only open source software. That sample is from the same driver (cheap paper, quick print):
Right now I'm trying to how it works and what doesn't work.
@ninj, I might give the...
I'm having problems establishing good printing work flow. I have calibrated monitor (Agryll + ColorHug), but I'm struggling with gutenprint/cups. The problems are:
- red goes pink, even with all profiles/correction switched off
- heavy banding (*) on blue (also green, but that's probably from...
OK, I was not aware of versions - color management is fairly new stuff for me. I tried to merge to profiles and, yes, they have different versions. The one that is crashing the system is 4.2
$ file r2000luster290118rkin.icc

I got a few icc files for ink/paper from Marrutt and I hit a strange problem. The files seem to work with gimp (no crash), but they kill gutenprint (filter failed) and collink [1].
Any idea what might be wrong?
I can provide all details & debug data if there is anybody willing to look at it. I...
Thank you!
Looks like filling the cartridge up to the top made a difference. Before I tried with ~50% and after topping up to ~100% the printer seems to produce black. Tests in progress..
Lessons learned: when experiencing problem with a single colour - top up the cartridge to the max before...
More info: the black square at bottom-left also started to look different - I have no idea why.
Attached hoto sthows the details. PK added in gimp. Top pattern yesterday morning, bottom one a few minutes ago.
Any help will be appreciated - I enjoy fixing things, but I'm running out of ideas.
