Photoshop CS6: Raster a PDF/X3 is a big Problem on MacOS 10.7.4. The known X3 tessellation (thin hairlines that always been visible in Acrobat but never on prints) produces in Photoshop CS6 as a rastered image also thin hairlines. And that pixels ARE VISIBLE!

Yes of course i have exactly the same result when rastering the X3 in CS6. It's a fatal problem!

This looks like a problem we've seen from InDesign saving tiled images -- they don't rasterize well anywhere except Acrobat (and we suspect that's due to luck).

Photoshop CS5 and earlier would show artifacts at some resolutions, but not all.
Photoshop CS6 changed to a higher quality rasterizer, and started picking up the edge artifacts from the image tiling. (and we're still not sure why InDesign saves PDF this way -- it's bound to cause problems)

Do you have an example image you can share with us? We need more evidence to light a fire under InDesign and the PDF folks to get this figured out.

I suppose the transparency flattening necessary for X-1a and X3 pdfs poses some challenges – especially with affected images of different resolutions and rotations interacting – and the results are intended to be economical about resampling image( part)s.

Edit: Also does Illustrator not behave the same way as Indesign in that regard?

Hi Chris,

i have just created an example package (AI File and PDF/X3) with screenshot documentation of the way you can reconstruct this problem.

The artifacts always appears if you have a spot color like pantone xy, and a dropshadow or transparency or sth else on top.

Hope this is helpful and get to be solved.

Here is the DL Link of the package: https://dl.dropbox.com/u/58619312/PS%...

I downloaded the file - thank you. Yes, something is causing the PDF X settings to create files that just cannot be rasterized correctly except at their original image resolution. The PDF rasterization team is rather frustrated by this.

There must be an option to rasterize X3-PDFs in the old way in current Photoshop Versions!
You can't keep CS5.5 on your computer just in case you get anything else than X4.. Can you even buy that software? It's ridiculous!
The problem is around for 7 years now, we have Photoshop CC 2019 and still no fix

Mr.Cox already explained seven years ago what is going on so your choice of the word »ridiculous« seems unjustified. 

Why do you need to convert pdfs to pixel images anyway?
If the pdfs are intended to be processed in a pixel-oriented image editing application why is the transparency flattened? 

Can you provide a file for testing?

I get the point of the different rendering engine. But you can't deny the problems.

A common case is is to do mockups, sometimes of PDFs in X3 standard where we don't have the sources (no X4 available).
There was also a logo which had to be exported in X3, because X4 leads to a gray area.

We have to work with what we get, we don't have the opportunity to ask for "proper PDFs"

I'm sorry I can't provide you with the file to test by yourself but that's the result.

Upper left: the only way to get the logo right on the picture.
Upper right: X4-Standard with gray area under the logo
Down left: sweet white lines all over the logo in a current Photoshop version
Down right: black line plus gray area.

the most dangerous point about this issue is: You can't trust Photoshop. Always check the PDF/x version and review the rasterized pdf afterwards.

The »gray« around the Drop Shadow in PDF X-4 was news to me, do you know if the pdf hails from Indesign?

You may know this already but just to be sure: If the pdf has an image or color background the white lines can sometimes be remedied in Photoshop via Layer > Layer Mask > From Transparency and then removing the Mask without applying it.

Thanks for this tip, it's new to me and my be a good workaround (but not 100% working)
I just remember this Logo which is quite complex. It's an Illustrator file, placed in InDesign. Have not seen this a lot but seems to be another flattening issue.
