I'm amazed that iQueue doesn't support LZW compressed TIFFs. Bummer.
Anyone know of plans for this to change?
Incoming LZW is matched, but LZW compression for outgoing TIFF data
isn4t supported at this point.
Incoming JPEG is a lossy compression and must be decompressed before
matching. You can then recompress the object, depending on whether it
is in a multi-object format (PS, PDF) or a single-object format
(raster images). The command 'Recompress JPEG' is for decompressed
objects in PS and PDF. The JPEG command in the Raster Format Options
dialog is used, if you convert say incoming TIFF or Scitex CT to JPEG.
Hope this helps
BTW anybody know of an analysis tool that goes beyond InProduction to
look into the color spaces in PostScript Level 2, PostScript 2017 and
PostScript 3? It's hard enough to analyse color internally in
applications, harder still once applications have written PostScript
or PDF. At the moment I'm pondering the InDesign PDF libraries versus
the Distiller PDF libraries. If you feed the same RGB recipe with the
same Adobe RGB 98 profile through InDesign for direct export to PDF
1.3 you get one color which Reader shows EXACTLY the same as InDesign
does. If you feed the same RGB recipe through XPress and via
PostScript into Distiller where you retag the Adobe RGB profile, you
get another color (much darker). The RGB recipe can be checked in
Illustrator 9.02 and is the same (barring slight rounding as QXP only
accepts RGB as percentages ... -:)).
