LSI wants interiors with color to be built to the PDF X/1:2001 
standard which is about PDF 1.3 in antiquity.  It is alleged that 
they search for this tag line in the pdf.  They are by far the 
biggest digital printer in the US. 

Covers with LSI may be a different matter but transparencies like 
those used in the Freedom Yug tutorial may still cause problems. 

If there is no way to "flatten" a file in Scribus what would be the 
most useful external flattening program to use for a: Linux and b: 

Gimp won't output anything with CMYK color model (other than 
separations) so that won't help.  Will ImageMagick flatten files?
