My thesis cover has an image that stretches over the entire pagewidth. This is nice in PDF, but I expect that the outer few milimeters cannot be printed. In indesign or similar programs, the printed document can be larger than e.g. A4 format, with print margins. You can provide an image that is slightly larger than the pagewidth, toghether with cutting/print markings that show where the paper should be cut, which will then remove a small portion of the image, but results in no whitespace at the sides.
Can I also do this or something similar in LaTeX and if so, how? I guess I could make my cover in InDesign or PhotoShop, but I would like to use LaTeX for this.
