BIZARRE "BLOTCHING" on printed image...

[Dannybex]

Hello,

I use photoshop to create digital artwork which is then printed on canvas.

I've created over 100 images with no major problems, except for this one particular image. (And it's one of the better selling images...)

Each time I print this image, a "blotchy" spot or two appears on the image -- in different places each time. :confused:

A couple of times this blotch is in an innocuous area, so it's not a problem. But other times it will appear on the subject's arm, his neck, or on a smooth part of the background.

I don't think it's a printer problem because like I say we don't have problems with any of the other images. But it seems to appear on this image only.

Does anyone have any suggestions or remedies? It's almost as if this image is hexed? Very bizarre...AND frustrating.

Any suggestions would be sincerely appreciated! :)

THANK YOU,

Dan

That s pretty strange!. Did you generate the image for yourself? Thouhg not sure, I think it could be some kind of action that executes every time you print. If you re using PS CS2 check for File>Scripts>Script Event Manager and see if the Enable events to run Scripts/Actions: check button option activated.

Are you getting these prints done at a commercial printer?

If so and they are producing their plates from negatives I would suspect Thats where the problem is coming from.

I've been in the printing industry for almost 20 years now and its not uncommon.

I'll give you a little run down on what "might" be happening. (of course if the prints aren't being printed at a commercial printer this will be all in vain)

The scenario:
You bring in your art and they produce negatives (4 of them to produce color images... Cyan, Magenta, Yellow and Black)
These nagatives are then "stripped" (positioned for platemaking)
In this stripping process alot of printers still Place the negatives on a piece of mylar that is punched with holes at the bottom to hold it in position for plate making.
Each of the 4 negatives will be placed on its own mylar
Now at plate making time, A press plate with the same punch pattern as the mylar is placed on the "plate burner" and then one of the 4 negatives taped to the mylar is placed over it.
the plateburner glass is closed and a vaccuum sucks all the air out keeping the mylar/negative and plate in solid contact with one another.

>>> here is what I think "MAY" be happening<<<<
If one of the negatives has the slightest buckle in it while attached to the mylar when the vaccuum is turned on its not going to lay down on the plate everywhere, and chances are its not going to be the same everytime.
