Artifacts / Stripes in JPEG after Retouching/Opening in PS

Hi there, community!

 

We've encountered a huge problem with some JPEGs we retouched for print.

Either directly after opening them in PS or after saving and closing the image (mostly the case) it's getting

some kind of horizontal stripes / artifacts. Problem is, sometimes they only appear after saving the image, so we'd have to reopen every one a few times to make sure this error does not occur. Also, the images look abolsutely fine in the preview AND wehen placed in InDesign. Sometimes they're visible in the exported PDF, sometimes they aren't and we eventually find out when the product is already printed. Any help with this?

We're running CS6 on OS X 10.7.5 with newest patches and Updates. All images are HQ stockphotos from familiar sites.

 

Regards,

Bene

    Does this also happen with tif?

     

    Do you keep the layered files as psd, psb, tif?

    Of course we directly paste the PSD into ID, no image exporting.

     

    Now that seems like an unwise practise if I understand correctly that you do not place images in Indesign but rather paste them after copying them in Photoshop.

     

    Are multiple machines affected?

     

    I think in the past similar issue have arisen and the possible causes iincluded bad RAM … so it may be difficult to trouble-shoot.

    What are your exact specs (Photoshop and OS version, GPU etc.)?

    Does turning off »Use Graphics Processor« in the Performance Preferences and restarting Photoshop have any bearing on the issue?

     

    Boilerplate-text:

    Does turning off »Use Graphics Processor« in the Performance Preferences and restarting Photoshop have any bearing on the issue?

    Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by pressing command-alt-shift/ctrl-alt-shift while starting Photoshop until the appropriate dialog appears after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)

    Good that it’s resolved.

     

    Adobe does not offer support when it comes to working across servers with Photoshop.

    Basically Photoshop users are expexted to work locally – of course many of us do save across networks; but one should keep in mind that if issues arise with any such set-up one need not blame Adobe.
