As you may or may not know, Adobe's Image Ready support ZIP compressed TIFFs (reading and writing), but they use a different tag for the compression scheme.

If that's the case, then it's also true for other Adobe products (Photoshop, ImageStyler, InDesign, etc.) since they all use the same technology (and shared libraries) for doing image processing.

Haven't tried it with InDesign just yet. PS 5.5 (for the Macintosh) reads Deflate compressed TIFFs. Cool. Thanks for pointing this out.

I don't know any of the specifics of what they are doing, but I do know that Adobe has been working on a TIFF 7, that incorporates a number of improvements.

Cool.

I am on the list, but I don't work for Adobe anymore...

My bad. Sorry.
