PDF x1a:2001 and Context

PDF x1a:2001 and Context

[John Culleton]

PDF X/1a:2001 is an old pdf standard still required by some important 
American printers. Han The Thanh et al. has created a package for 
pdfLatex.  I wonder if there is a route to this output using Context?

To satisfy some US printers (e.g., LSI) the file must actually meet 
the pdf/X1a:2001 standard and the file must be labeled as such 
internally.  It is not difficult to modify the file to pdf 1.3 format 
which is essentially the same thing as pdf/X1a. But the internal 
labeling is the problem.  The standard solution is to run the file 
through Acrobat Distiller. But that is not an Open Source product. 

If the file, typically a cover layout, does not meet the above 
requirements then it is pre-rasterized by the printer prior to 
prepress in some product or other which degrades the quality of both 
type and  especially bar codes. 

It is perhaps not a problem that you choose to address in Context.  
But I am trying all avenues looking for an Open Source solution that 
can meet these draconian requirements.

It shouldn't. You should use vector type and vector barcode, not bitmap
(ie gnu barcode  makes eps output) .
Eventually you can convert a pdf to a TIFF by yourself with ghostscript
