: Dpi vs effective dpi When getting an InDesign file ready for print I knwo that images should be: 1. CMYK 2. at least 300 dpi 3.preferably .tiffs But if the files are less than 300dpi but due

@Gail6891361

The printer does not really care about what the metadata of the image said before you scaled it in the page layout software. THis is what the original designer wished. You, the pagesetter, are by no means bound by that decission.

Your override is now for all intents and purposes the new PPI in your final document (unless say your pdf export setting is instructed to resample the images beyond sertain size). So only effective PPI counts.

But other than that the guidelines you lay out in 2 is just a guideline you can easily live with less, and number 3 is not really a requirement in a modern workflow.
