PDFs from Quark 7.3 still a problem
Sadly even after the long awaited 7.3 update the ‘export to PDF’ issues are still there. Quark updated there pdf export setting in 7.3 to try to sort out issues with the compression of images, this unfortunately has backfired somewhat as we have found out to our cost recently.The only way to overcome this problem is take off the compression of images and set them to ‘none’ which has the obvious problem of file size.

Gemini have performed many tests on the compression of images within the Quark export to pdf settings, and found that there was only a couple of instance where compression made no difference. This was where the picture was exactly the same dpi as we were trying to downsample to ie. the setting was set to ‘downsample’ above 320dpi to 300dpi this seemed to make little difference to the picture quality, however if the image was 600dpi and it was downsampled to 300 the image showed signs of pixelation!

The result is if you export to pdf from Quark 7 you had better check carefully the images in the resulting pdf as they could look dreadful when printed, my advice is to take off all compression and live with the large file size for time being until this is adressed by Quark inc.
