Stripes in print (Gimp 2.6.7)

Hi,

after editing a photograph of a girl I downloaded for free from Stockvault, I printed it out at a local drugstore (on one of those Kodak stations), but unfortunately the print contained a
pattern of fine stripes. The woman in the drugstore told be that this must be due to to file. To test this, I printed the photograph out at another store of the same chain, but the stripes were still present, albeit not as strong as in the first print.

My question: Did anyone experience this as well, and what can I do to avoid this in the future? I really zoomed in on the file (I'm using Gimp 2.6.7, and my display is gamma-corrected), but I couldn't detect any stripes.

The file can be found here:

Thanks for any recommendations,

Claus

There *is* a very prominent stripes pattern in this image.

Is this the file you're trying to get printed, or a copy of a resulting print?

Regards, Michael

I see the stripes as well, but also a horizontal shift, as if there are two foto's.

The shift is intentional. Regarding the stripes: I found out that this is a gamma issue.On my
(gamma-corrected; gamma = 1.0) display the stripes are not visible. If I reduce the
gamma to 0.5, the image becomes visibly darker, and then I can see the stripes as well.
The Kodak system on which I printed the file has no gamma correction, either--thus the
stripes. I made a simple image file to check the gamma of the Kodak system, in order
to find the proper correction value. Then I'm hoping that the stripes should disappear.

Thanks to all who responded.

Claus
