I'm designing a photo book for a friend and we're having output issues. We're working with a professional printer but for some reason our prints keep coming out soft or pixelated. The images are 300 dpi and formatted correctly for an InDesign document so the issue is likely output.
What's the best way to output the HIGHEST quality PDF you can out of InDesign? Everyone seems to have different answers.
Thanks in advance!
Check a couple things.
One would be for broken links. If there are broken links then ID will use the preview image instead of the linked image.
Another would be to select an image that prints poorly in the Links Panel and check the effective resolution. If it is below your stated 300 dpi then the image has been enlarged greater than 100%.
Then just use the PDF/X-4 profile for your PDF.
