Subject PDF Output consideration 1.3 vs. 1.4
Date Sat, 11 Jan 2003 18:32:03 GMT
Since you are currently discussing PDF 1.3 vs. 1.4 issues, there's one 
thing not
all of you may be aware of:

There's a relatively new standard called PDF/X-3. This is basically PDF 
with a number of restrictions. Some can be handled by the user (all fonts
must be embedded), some others must be adhered to by the PDF generator.

The intention of PDF/X is to standardize on a PDF subset that can be

mismatched fonts, color mismatches, trapping etc.).

preflight tool called PDF/X-3 Inspector (download URL: 

The reason I'm mentioning this is that one of the restrictions of PDF/X-3 
that the PDF file may not be PDF 1.4 (I'm not sure if lower than 1.3 is 

To pave the way for future PDF/X support, you may consider still 
PDF 1.3 in the redesign code tree. At least perhaps make it configurable.

Hope this information is useful.
