Digital BW, The Print

Steve

Many thanks for the reply. As far as I can see printing using a 
custom grey icc profile instead of Same As Source seems to linearise 
the printer. I tried the following experiment:

I printed the IJC 21 step file first with Same As Source as print 
space profile in PS CS and then with my own custom grey icc profile. 
I then measured both and saved the L values as a text file. I then 
imported them into IJC linearisation page (MAC version) just to see 
what the values looked like. Result the grey icc profile values 
produced a virtually perfect -4 down curve. The Same As Source values 
were not as accurate.

Form this it seems that using a custom grey profile instead of Same 
As Source is certainly beneficial.

Any comments.

Peter.
