Now if the internet connection is really a big stumbling block, that's
why I'd raised the idea of a subset profile. There are six tables
getting embedded with an output profile (up to six anyway), and only one
of them is really needed, the A2B1 tag (device to PCS colorimetric). And
a portion of the B2A1 tag would be helpful if the image needed to be
reseparated using black point compensation (basically the black point
information).
Actually it's possible to achieve a very similar result while having the
profile remain ICC compliant. The different intents can all point to the
same table (so only two tables worth of data), and the B2A table and gamut
table can both be very low resolution (say 3^3 = 27 entries). I often
generate profiles a bit like this when I know I'm never going to use the B2A
tables.
