Hello everybody,

Well, we just got a new printer, one that can print photos. SO is extremely happy but there's just one problem. We have two very nice baby pictures that print out with weird grey blobs where some reddish color should be. One has the whole open mouth and lips of the baby grey, the other has a reddish spot on the side of the baby's nose grey.

-It can't be a technical problem with the printer since dozens of other photos turn out just fine...
-It can't be a problem that happened when taking the picture because it can be viewed just fine on any support (camera, TV, comp)...
-It can't be a file type problem since pics were all taken with the same settings on the same camera (so it can't be a matter of color scheme being bad, what with RGB, CMYK and company)...

We're at a loss. Any clue as to how we could diagnose the problem? Both the printer's and the camera's manuals failed to provide an answer.

Thanks!

Never rule-out problems without proof.

The problem is that the other pictures are not the same as this picture, so it could be a technical/file-type problem, jsut because the other pictures print fine doesn't mean there isn't a problem, the "problem" might jsut be unapparent in the other pictures.

So convert copies to different different file-types, and if that doesn't work go over the technical troubleshooting.

(And, you can't rule out a problem with taking the picture either, jsut because the problem is not visible while viewing, doesn't mean it doesn't exist (there)).

Make sure the color profile settings are correct. Most printing is not directly RGB to CMYK. It goes through a color management system to make sure the colors are correct. However, if the color management system has the wrong profile (for a different printer) then problems like the one you describe can occur. (Although it does sound a little unusual.)

I've had problems printing to a high-end Epson printer with colors being out of gamut (color-range) and the printer got confused about how much ink to lay down. This resulted in either too much or not enough red (and, yes, it does always seem to be a red color). You can send me one of the pics and I'll be happy to look at it for you, check to see if those areas are out of gamut and correct it if necessary.

At the Canada Day celebration today, London Drugs had a booth where you could print out digital camera photos for free. When I tried it, my picture printed out with a green tinge. I assumed that this was because the printer ran out of red ink, but the man running the booth insists that it was probably a problem with my camera and my computer that made the picture appear normal before.

Thanks everybody for your suggestions.

Well, we tried to change the color scheme from RGB to CMYK and waddyaknow, the bugged pictures printed out fine. I'm really puzzled though, how come RGB colors would pose problems for only about 5% of the pictures we've printed? And how come the problem affects a whole area (in one case, the open mouth of a baby) spanning several tones of red/pink instead of being limited to a few precise shades? [Confused]

Oh well... technology... Very simple when it works, but so puzzling when it doesn't. [Smile]
