When importing a PDF with images, Photoshop CS6 adds faint outlines to the PDF image segments in the file. Prior versions of Photoshop render the PDF correctly. See the attached image for an example.
Cris, u tell us that the PDF is not written properly. We understand this now.
But please tell us also if it would be a great thing to just create a droplet or little app that just has the function to rasterize the pdf using the CS4 render engine for example. U think it could be done easily? So we could use this little programm to rasterize this bad PDF files.
No, I don't think there is an easy solution. The files are written in a way that cannot easily be rasterized without artifacts. Again, you still got artifacts in CS5 and earlier.
Chris please tell us the truth:
WILL THERE BE A SOLUTION FOR US? Is someone working on this problem?
And please stop repeating that the error accoured also in earlier versions. It may happen in some resolutions and under some rare circumstances, BUT i work now for over 20 years with Photoshop and i NEVER had this problem rasterizing PDF's. OK? Ask everyone in this thread and they will tell you the same.
JUST NOW WITH THE NEW VERSION, so PLEASE PLEASE stop deflecting. Thank you!
... and THIS will not help us with the problem that we have with the already produced pdf's from our clients that we have to open. But i see it clear now: NO HELP FOR US FROM THE ADOBE-TEAM. Just talk talk talk ....
Very disappointing!
Yes, Photoshop CC has the same problem. Please Chris, do not more involve in this discussion until you can give correct informations, you didn't get the problem at all.
The following very simple test proves that the artifacts definitely are not part of the pictures inside the generated pdf: Simply import the PDF in Photoshop and select "Pictures". In this case the ORIGINAL tiled pictures are opened in Photoshop without any rendering process. Then you can put the tiles together by hand, simply drag and drop them into an empty file. Zoom in, and - what a wonder! No artifacts on the edges. Works with every version up to CC. Chris, you are not knowing what you talking about.
The images are tiled by the application that created them, and because of that tiling they cannot be rendered correctly at resolutions less than their original resolution.
And opening the tiles at their original resolution has no bearing on this problem.
Chris, that is right. But the issue is, that since CS6 the artifacts appear always, even when you render it with the original or higher resolution. As I mentioned before: When the artifacts didn't appear, when you rendered it at the original or higher resolution, then we had no problem, because we could render it this way and reduce the picture size in a second step. But this is not possible, because the artifacts show up on ANY resolution.
Again, the problem is with the PDF file and the tiled images inside that file. CS6 just made it visible more often by using improved rendering quality.
And you are not getting tired in calling this an "improvement". Which kind of PDF should profit from this improved rendering when the most complicated file type, for which the old rendering process was perfect and which was often the only possibility for putting the tiled images together again, ist not working anymore. Probably Adobe thinks, that this feature is not really an important one, but this is wrong, because there is no similar function throughout the whole Creative Suite. It is very sad: I do not have any hope, that this issue comes to a conclusion.
It is an improvement. The fact that it exposed bugs in the PDF files created by other apps doesn't mean that the antialiasing did not improve in quality, and that the files don't render faster. And the old rendering STILL showed artifacts on these files. The change in rendering just made the problems in the PDF files more visible, but the problems in the PDF files existed even before the rendering change.
Please, read the existing posts in this topic.
Please read the previous comments - this is not a bug in Photoshop, just a bug in the applications that created the PDF files. Changes to Photoshop are highlyl unlikely to fix a bug in the PDF files.
But it is a fact that it worked before, now it doesn't. The only thing that changed is photoshop, the applications used to create PDFs are the same.
So repeating this does not make it the truth. 😉
No, that is not a fact, and is false. Previous versions also showed artifacts, just at different resolutions, and sometimes less noticeable.
And I am repeating the facts: the problem is in the PDF files, because of the poorly tiled images. Those are created by the app that created the PDF. There is no good way to rasterize the PDF and avoid the artifacts caused by the tiled images in the PDF files.
yes cris, this could also be real and the truth, BUT (!!!) we need a working solution to be able to continue our work. OK? why its not possible to implement the older rasterize method in photoshop as an option? so we could choose? Or just make a standalone droplet/app just for rasterizing the pdf's using the old CS4 code? is this toooo much effort and work? Come on: you guys make this little app in no time, right= 😉
Or should we try to use GIMP (http://www.gimp.org/) or GIMPSHOP (http://www.gimpshop.com/) for rasterizing the pdf's (and maybe more)?
When some Adobe apps "flatten" transparancy or effects, they subdivide the image into boxes of flattened pixels. Those boxes actually do accurately butt up to one another, and therefore shouldn't have thin white slivers of white space between them. When these PDFs or EPSs are rasterized (drop file directly onto app icon) Photoshop CS5 handles them correctly and does now show slivers of white or tranpsarent lines alone the box edges. But CS6 and CC both handle this incorrectly and leave white lines.
The has to do with the Anti-Aliasing engine, since if I turn off anti-aliasing, the lines disappear in CS6 and CC but now all vector text has harsh jagged edges. But in CS5 you can leave Anti-Aliasing on, and it will give you both smooth text, and no white slivers on the box edges.
So in short Photoshop CS5 good, Photoshop CS6 and CC bad.
Here is an example file from my dropbox for you to download to test this. Drop this file onto Photoshop CS5, CS6 and CS7. Go ahead and rasterize with Anti-Aliasing on at the default size 8.5" x 10.646" at 100dpi in RGB.
Please read the existing topic first. The problem is not in Photoshop, CS5 still showed artifacts (just at different points, and sometimes not as noticeable), and there's not much Photoshop can do about the bad files.
Are you kiddiung us Cris?
Sorry, but i feel that you have ni intention to help us and you are nit even willing to understand our problem. You just repeat the same thing over and over again. we can not wirk with this "improovement" but we could with the older version. Now dont tell us again that also the old method was showing artifacts... we all had no problems with that. So please why you guys dont give us a little app just for opening the pdf's using the old renderer? Why not? You can't or you want not? is this the care you show for the pro-clients???
