Ntracks Posted April 25, 2019 Posted April 25, 2019 No matter which option I choose, all pictures are compressed in a wired way. I have attached, the original from the Publisher. And the exported PDF. - The Images on the bottom are looking okay to me.

Joachim_L Posted April 26, 2019 Posted April 26, 2019 Which setting did you use for PDF export? In Ressource Manager all images were up-to-date? Have a look at the attached image. On the left your PDF, on the right my PDF. ------ Windows 10 | i5-8500 CPU | Intel UHD 630 Graphics | 32 GB RAM | Latest Retail and Beta versions of complete Affinity range installed
Ntracks Posted April 26, 2019 Author Posted April 26, 2019 Im using "pdf for print" - what is suspicious to me is the info in the brackets (nothing will be rendered) The Ressources look okay to me!? This is what the pdf looks like with 400dpi. No difference.
VolkerMB Posted April 26, 2019 Posted April 26, 2019 Hmm... I get the same results as Ntracks: a PDF that is heavily pixelated! But the PDF looks fine if I rasterize the image in question before exporting the document to PDF. Ntracks 1

The resolutions is still lower than the origianl. But it looks way better than the first outcome! On 4/26/2019 at 6:41 PM, Patrick Connor said: Thanks for your report.

Staff Sean P Posted April 29, 2019 Staff Posted April 29, 2019 Hi Ntracks, Thank you for the documents. The reason you are getting the issue is because you've got a very large resolution image which is then being massively shrunk. Because it is being shrunk the image has to be resampled, but due to the very contrasting pattern you are getting a moire effect. There are three things that you can do: 1. You can use a different resampler on the PDF export. I found your file to work well by setting the Resampler as Lanczos 3 Separable. This gave a much nicer and smoother looking result 2. You can resize the images manually yourself and place them in. 3. You could disable the resampler on the PDF export by unticking 'Downsample Images', however this will make the file quite large, and depending on the PDF viewer could still give the moire effect. Please note that the image will always be quite a bit lower. The pixel region of an A4 page at 300 dpi is 2480.3px x 3507.9px, the pixel size of the source images are 4000x6000 (almost A3 size at 300dpi), and they are then placed on the page at 362px x 543px. So essentially it is trying to shrink 4000 pixels into 362 pixels! Hope that helps!
