Interesting questions of copyright though. I wonder whether they have
permission from all the artists to have their work on their site?

Much better layout and user interface than before. Thanks. Although, "click
for large exhibition print (40k)" is still a bit amusing.

Right you are, I should have thought of that.

I'm a noob in the dark with this stuff, trying to
retrofit curves from one printer to another.  So far I
have only applied the neutral curves to the test
patterns.  I combined "21-Step+.jpg", "100 step 1 line
greyscale strip.jpg", "100-step wedge, 8bit,
Grayscale.jpg", "OffsetGrad8.jpg" into one file and
used that for the testing.

What I have found is that the 1270 curves, both mac
and pc, produce a pronounced stepped gradiant, with
steps at 90% and 65%.  The 1270 curves also are much
flatter between 65-75% and 40-60%.

The 1280 curves seem to be much better at spreading
the range around, although a much less pronounced step
is visible at 65% and 90%.  The 1280 pc curve does not
go pure white (that is, no ink) at 0%, while the
1280mac curve does.

Interesting stuff.  It takes a fine eye and lots of
ink to get these right I imagine ;)  I'll try the warm
curves next, since those ones produces the most
trouble in the output.

Thanks for the help and pointers ;)

MIS has posted a little tutorial for modifying curves that Dirk Hobman wrote
(I edited and supplied some files and forms).  It's in the MIS "What's new"
tab at:
http://www.inksupply.com/index.cfm?source=html/whatsnew.html

It might be useful to you.
