 |

I'm having an issue with photoshop. An image will be cleaned up for print, then for some reason or another it may be reopened. When it is reopened a 1% dot of CMY has appeared in the all 0% area. The operator will then clean the image to 0% again. If it gets opened again then the 1% dot is there. We've run some tests and anything that was cleaned and not reopened output correctly with 0%. This problem is occurring with full color jpegs on photoshop 6.0 and 7.0. 6.5 seems to do just fine. The color settings are:
Adobe RGB 1998
U.S. sheetfed coated v.2
dot gain 20%
dot gain 20%
all convert to working profile
ACE
Relative colorimetric
black point compression and dither are both checked.
I think that is all of the settings we are using. Any help with this would be greatly appreciated.
Thanks

Try upgrading to 7.0.1. There was a problem like what you are describing with 7.0. |

Thanks for the note on the upgrade to 7.0.1. That explains that issue. It did not however help with my photoshop 6.0.1's. Which I used last year when i discovered the 7.0 issue. 6.0.1 didn't have that issue, but this year our process had changed and now we were seeing the dot on some of our 6.0.1 boxes. We tracked it back to binuscan which saves a lower level jpeg. If we do a save as in PS and set it to max quality jpeg then the dot goes away. Very odd. So that is our fix for now. Thanks for the help.
Thanks

Right. That would have been my next guess. I think you still may see that even with C S 2 saving at low quality jpeg. |

I agree. It seems to just be a gretag artifact. I'd love to go all CS2, but we are still using some PS 4 copies. I can dream I guess |
