(The preview reflects this low resolution) If I right click and select Preview Settings, Full Resolution is checked. When I import it into Scribus, Scribus for reasons I can't comprehend decides it's 72 dpi: when I right-click and point to Info, it gives '72 x 72' as the 'Original PPI', and '66 x 66' as the 'Actual PPI'. If I open the PDF in Foxit Reader, for example, it looks sharp, and if I print it at 600dpi, for example, it also looks sharp - just as good as printing from the original program. I export a document from another program (in my case, a music notation program) as a PDF, with vector graphics and embedded fonts.

That's a difficult thing to measure in a PDF file. So you can see that, in PDF, the effective resolution of the image is a combination of the dimensions of the image, and the dimensions of the media it covers.

Since I am interested in the same kind of job (though not necessarily to OCR the PDF files, but to convert them to DjVu and then OCR them), I found this question and the responses lacking (since I needed to guess the DPI of the images with the number of pixels and then use the size as output by pdfinfo or other tricks-not to mention that the images inside a PDF may have different densities etc.).ДЄfter a lot of research more, I found that you can use pdfimages (from package poppler-utils) like the following: $ pdfimages -list deptest.pdf The effective resolution of the first image is 1000 dpi, the effective resolution of the second is 500 dpi.
