Can I use images less than 300dpi with the PDF-to-book platform?

Yes, you can, but any low resolution images will still need to be set to 300dpi, as this is the minimum print requirement of our system.

If you have received a preflight error when using our PDF-to-book platform stating that some of your images are of a low resolution (under 300dpi), you will need to change the resolution of the relevant images to 300dpi in order to 'trick' the system. This can be done in another software, such as Photoshop, and then resubmitted into your InDesign file to then export again as a PDF using our pre-sets.

Please note that changing the dpi of your image will not increase its print quality. This is just a means of getting past the minimum print standards our system requires. *Handy tip: how to check the dpi is over 90 on photos: select a photo in InDesign then click on F8, and it tells you the photo info including dpi.
