Some time ago I made a Open Type font family, regular, italic, bold and bold italic. When I export a pdf from InDesign CS2 everything looks ok on screen, but when I print the pdf with Acrobat 7.08 to our Canon C2620 color printer I get a strange mix-up of italic and regular glyphs. It’s not in a random way, the scheme is as follows:
For Regular I get this:
Same result with italic:
Bold behaves as it should:
Bold Italic behaves like regular and italic:
One of our printshops had similar results, that’s the reason I jumped in and started to do some testing. I observed the following:
Printing the doc straight from Indesign CS2: OK, results as you should expect.
Exporting the doc from InDesign CS2 to pdf, and print that with Acrobat 7.08 to our Canon Color printer: NOT OK, see above.
Exporting the doc from InDesign CS2 to pdf, and print that with Acrobat 7.08 to our Canon B/W non PS-printer: OK
Exporting a similar testdoc with InDesign CS and print that with Acrobat: OK
Distilling the InDesing CS2 doc and print that with Acrobat: OK
Printing to pdf with Ghostscript: OK
I changed the font subsetting from 100% to 0%, no effect. All four styles have unencoded glyphs in the private use area, but I can’t see the relation with this strange behaviour. If I print to file with the canon printer and open the postscript dump, I can’t see anything strange (I am not a PostScript expert however). This postscript file will distill perfectly.
It all hints at an encoding issue but I can’t see why yet: the characters are in place, it’s the glyphs that are mixed up. Maybe an internal naming issue? The fonts were originally created with Fontlab 4.6, generating again with Studio 5 gave the same results.
Anybody any thoughts on this one?
