Hello Mike, hello list

If we are talking about a workflow with PDF/X spool files, where the PDF 
output intent is the printer profile with embedded driver settings, we 
still have to think about, how to transport the embedded driver setting 
to the driver (e.g. Gutenprint).
As Gutenprint needs a raster file as input, I would prefer, that the 
output of ..toraster contains has an embedded profile which is identical 
to the PDF output intent.

Gutenprint parses the rasterfile for an embedded profile, extracts the 
driver settings and is synchronized with the printer profile.

In a former e-mail, you rejected such workflow, without defining a clear 
alternative how top transport driver settings to Gutenprint, which are 
embedded in the printer profile.

Anything new from you about this topic ?

Best regards
