ICCs and linearization

2006-03-14 by Peter De Smidt

The ICC I made yesterday does not come very close to the QTRs ideal 
densities.  Here are the densities, starting with the lightest:

Step      no-ICC        ICC
255      .05               .06
242      .10               .11
229      .16               .16
216      .22               .21
204      .29               .26
191      .35               .33
178      .43               .40
165      .50               .47
153      .57               .55
140      .66               .63
127      .76               .72
114      .86               .81
102      .97               .93
89         1.09            1.04
76         1.22            1.18
63         1.38            1.32
51         1.52            1.51
38         1.67            1.71
25         1.81            1.97
12         1.99            2.16
0           2.19            2.23

In the Eye-One folder, there's a applet QTR-Linearize-Data. Could this 
be used to make a more ideal ramp? If one inputs the appropriate text 
file, you get a text file with the LAB data plus a line on the bottom, 
such as:

LINEARIZE="96.4 92.2 86.6 82 76.9 73.1 67.6 63.6 59.3 54.4 48.6 44.6 40 
34.4 29.8 24.1 20.5 15.9 13 9.4 5.4"

Roy says to "copy/paste this whole line into the profile file" .  Does 
this mean to paste into the ICC file?  I'm not sure how to do that, as 
Windows tells me that it can't open the ICC file.

Any help or suggestions appreciated!
