I would LOVE to be able to use high res (300dpi) background images since that is the only way to tile images, background images can be changed and controlled through CSS rather than in the markup, and because it simplifies the markup in keeping with the content/presentation split between markup and CSS.

Add CMYK and SVG support for background images, and we're cooking with gas!

All of these issues have been added to the roadmap, starting with support for background image resolution, then fixing the bug affecting TIFF image resolution, then support for CMYK images, then support for SVG background images. The exact order of completion and date of delivery may vary, but I would expect to see support for background image resolution making it in to the next maintenance release.

The Prince 6.0 rev 3 maintenance release adds support for SVG background images and for correctly using the resolution of background images; CMYK images are still on the roadmap for a future release.

Great job guys!

For SVG background images, can they be defined in CSS the same way as standard image types and their attributes? e.g.

h2 {
   background: url(img/print/h2.svg) repeat-x left center;
}

Yes, that should work.

Today we have released Prince 6.0 rev 7, which includes support for CMYK TIFF and JPEG images.
