I was trying to figure out how to get the thumb tabs to extend beyond the page crop lines but I didn’t find any setting in PTXprint. It would be nice to have a setting to do this.
In the mean time, I found that if I made a small change to the ptx-cropmarks.tex file and then adjusted the tab length, I could accomplish this. Here is what I changed (2 places marked with RJA change):
I basically changed the kern value from -1 to -15 and then I used a thumb tab length of 15.0 in PTXprint. Now it looks like this:
Cutting along the crop marks will guarantee that we don’t have any whitespace on the edge of the tab.
