A6 Printing Template

About

The file attached to this Gist in XCF format is a template ready for professional printing with correct bleed and safety margins applied for editing in GIMP. Feel free to download and use it for your own projects. I've created this file because while I found a bunch of instructions on how to set up the file, I couldn't find a good starter. Here it is! I've followed the instructions on The Online Printer's guide to preparing GIMP files, but I also welcome any additional tips.

Usage

  1. Download the file
  2. Make changes as required:
  3. Treat the first level of guides as the edge of your image. This is the bleed line, and you can expect that this would normally be cropped.
  4. Treat the second level of guides as the safety margin. You should not have any important content or imagery crossing this margin.
