Quote:...AFAIK you can create layers in a PDF for things like watermarks, print press marks & dielines, alternate languages, callouts, measurements, etc. that can be turned off and on while viewing the main layer.
You are not going to get this with Gimp. Look up interactive PDF
example, LibreOffice might be a possibility. Do your graphics in Gimp and the rest in some other application.

Edit: Just been playing with LO - Draw You can add layers and in Draw toggle visibility on/off. Exporting as a PDF throws up a host of options but I did get a combination (most of them enabled ) which preserved the layers which were back again on opening the PDF in LO. All a bit flaky since it is not something I use.
