dear list/Marti Maria

01.
Id like to construct an algorythm (and later code it)
for building a LUT based output profile

02. Profile spec (part of it)

B2A1 (ICC Media-Relative Colorimetric Intent)
8bit LUT
Input channels: 3 (L a b)
Output channels: 4 (C M Y K)
CLUT-points: 32
(Index runs from 0 to 32767)

03.
I have the following table (only example):

Patch    printer input    measured printed output
nr       L    a    b      C    M    Y    K
0        10   5    8      55   80   90   2
1        20   -5   -9     10   80  100   20
2 ...
etc up to 1000 or so

04.
Id like to generate only the B2A1 table now.
How can i do it ?
Its practically a little profiling sw. 

05.
Any help just to go in the right direction ?



thank you
joe
