Ok, I'm using Gimp, and bought a new photo printer, and Epson Stylus Photo 1400. Great printer. I have the guten print drivers that are very powerful, and interface with the 1400. The problem I have is that now when I print, the faces turn out very orange... I am doing a lot of searching to find out if there is an easy way to adjust the colors output without doing it randomly.... I already ordered a spyder II for checking the monitor colors, but it seems that most of the error is in my printer output. I am using a custom ink feed system with non epson inks, and my paper is an inexpensive bulk supplier. Is there a system to adjust using the guten print drivers? Help!!!

Have a look at Joel's site - he has done something about printing. The link is on the sidebar at mtg.
Sorry, I have no time to go deeper into this - last preparations for school tomorrow....

Ok. I read everything at the linux photography site about color management. I have the monitor spyder2 on the way, although I don't think my monitor is that bad, or the source of the problem with the printer output... Perhaps I'll use it and then re-sell on ebay.. I also sent for an ICC printer profile for my Epson Stylus Photo 1400 printer combined with my Continuous Ink Supply System, and a full case of glossy photo paper that I have been sitting on for a couple of years.
I tried tweaking the color inside the gutenprint screens, but I get so close, and then it still looks like crap. It is difficult to know if it is the printer giving the problems, or just the conversion from sRGB to CYMK that the printer must do.
Hopefully the ICC profile will help me create some great prints....

A little bot OT: What have you paid for the Spyder? Did you by it new or 2nd hand?
What is your expectation in price when you sell it again? Maybe I can by it directly from you?!

Oh really? Cool, it's much more expensive here in Europe. Maybe I should consider buying it from the States.

Monitor Calibrated. I did notice a change when I applied the monitor profile to my compaq lcd screen. I entered it into the gimp color management, and it mangled it. I think it was because I already entered it in ubuntu, and gimp was trying to apply it twice. Something to remember. If anyone has a compaq C700 presario dual core and needs an icc profile?

I am still stuck adjusting my printer using guten print. Not Good. Please help, I don't want to load Vista back on my laptop....
Does anyone use ICC custom profiles for their printer in Linux? I have searched and searched and can find nothing about:
1. how to get an ICC printer profile for use in Gimp under Linux.
2. how to install the ICC printer profile in Linux or Gimp.
I obtained the profile for my monitor, and installed it from inside the terminal window per Argyll instructions. But my printer output is still not close enough to what my monitor shows....

The first thing I'd mention is that the screen and printer will have different gamuts, and they will never be able to match. For example, a bright cyan (0R, 255G, 255B) will not be able to be printed on any printer in a way that matches the lightness that you get on a screen. Once you accept that, there is a major issue of using custom inks, which will throw any calibration out the window. I might suggest talking to someone who has Photoshop and a set of swatch books. Just about any graphic designer would be able to help with that. Have this person print some color swatches out on your printer, and compare the printed output to what you see in the swatch book. If they don't match, I'd suggest figuring out how much color cast there is on each of CcMmYK, and adjusting the output accordingly. When you get it just right, I'd probably turn it into a filter in GIMP. |

When you get it just right, I'd probably turn it into a filter in GIMP. Yes, I understand the Gamut thing. But isn't the whole purpose of becoming ICC compliant is that you can now use ICC profiles??? That is the most accurate way to convert what the monitor color is to what is on paper. I already did adjustments in guten print until ink is coming out my ears... and it is not just a simple "filter" adjustment. I get the grays right, and the flesh tones are off, adjust for flesh tone and the Gray is off.... I understand that even given an accurate ICC profile, that there are certain colors that will not convert accurately, and are subject to the interpretation of the profile. But at least that would give me a base line to adjust to what looks best..... My question seems like such a simple one. Is there or is there not a way to use an ICC printer profile in Gimp and Ubuntu?  ? |

I recently struggled myself - not with icc for my printer but rather with getting it working at all...
Have you posted your question at ubuntu-forum or ubuntuusers? They are quite helpful and experienced...
