Could you please look at this PS file and offer some insight into why it isn't converting to TIF? It appears to me it's a font issue, but I'm not positive.
Created attachment 351 [details] File that does not convert to TIFF File from customer
The file appears to be truncated, stopping in the middle of the Setup DSC section. The end of the file (starting with line 3024) looks like: %%BeginSetup %%IncludeFont: HelveticaInserat-Roman %%IncludeFont: Minion-Regular Adobe_level2_AI5 /initialize get exec Adobe_Illustrator_AI5_vars Adobe_Illustrator_AI5 Adobe_typography_AI5 /initialize get exec Adobe_ColorImage_AI6 /initialize get exec Adobe_Illustrator_AI5 /initialize get exec [ 39/quotesingle 96/grave 128/Adieresis/Aring/Ccedilla/Eacute/Ntilde/Odieresis /Udieresis/aacute/agrave/acircumflex/adieresis/atilde/aring/ccedilla/eacute Ghostscript ends with 34 elements on the stack, as I would expect from the above, and since no 'showpage' is executed, no output is produced. Adding a showpage manually, a TIFF file can be produced, but it is most likely an incomplete image. Since Ghostscript appears to operate correctly, and the file appears to be invalid (incomplete) I am closing the bug.
