Page 69 of the TIFF 6.0 Specification says that "In a separated image,
each pixel consists of N components. Each component represents the amount of a
particular ink that is to be used to represent the image at that location..."
Does this mean that there can be no extra samples in a separated image?
Further down on the page, the Specification says "BitsPerSample =
8,8,8,8 (for CMYK). SHORT. For now, only 8-bit components are recommended.
The value "8" is repeated SamplesPerPixel times." This raises the following
1. "BitsPerSample = 8,8,8,8 (for CMYK)". Does this mean
that CMYK images cannot have extra samples? What about
non-CMYK separated images?
2. "For now, only 8-bit components are recommended." Does
this mean that extra samples must be confined to 8 bits
3. "For now, only 8-bit components are recommended." Are
there any cases in which 8-bit components are
recommended but not required? Must extra samples
(assuming one can have them) be confined to 8 bits too?

receiving them via electronic mail in order to ensure that I get them. (It is
possible that some USENET reply articles might not show up at my site.)
