Could someone send me a file that is created with the Eye One
and Measure Tool so I can edit files made with the SpectroCam
that they suit QTR-Linearize-Data and QTR-Create-ICC ?
If possible the 4 versions 21, 51, random, etc.

Hi Ernst,
The input files to QTR-Linearize-Data and QTR-Create-ICC are very
flexible.
It'll understand most any text file data organized in columns. The
columns
should be separated by spaces or tabs.
The important columns are:
1) Gray -- 0 to 100, basically the same as K in Photoshop.
or RGB -- 255 to 0, can be used as a substitute for Gray.
if missing it assumes N evenly spaced samples
2) L, LAB, LAB_L -- > 0 to < 100, the L measurements
3) A, LAB_A -- A measurements (optional, A=0 if not there)
4) B, LAB_B -- B measurements (optional, B=0 if not there)
or D, Density -- 0 to 4, density instead of L values, but no color
then.
duplicate samples are allowed -- they are averaged.
a trivial example:
Gray L A B
0 96.1 1 2
50 56.3 3 5
100 15.8 -2 -1
-----------------
Trying to copy the MT output is way more complicated than needed.

I would like to thank everyone for helping me in this case. I
will report back what the easiest solution is with the
SpectroCam. There will not be many around with that
spectrometer but it still does a good job here.

Hi Roy Regarding the information below. Will QTR-Linearize-Data and QTR-Create-ICC take density measurements measured in RGB_R. My densitometer gives these measurements. So what I am wondering is if at a given grey % can I enter RGB and Density values and have Create-ICC understand it. If yes, how would I enter that info, ie does Create-ICC recognize RGB columns? Thanks John E The important columns are:

Hi John, It recognizes headings of either RGB or RGB_R. The values should be 255 (white) through 0 (black). Density numbers are fine, values are between 0 and 4. It's much easier to try it than figure it out. Roy On Wednesday, August 2, 2006, at 03:26 PM, john eckenrode wrote: > Hi Roy > Regarding the information below.

Thanks for the info Roy. Its funny, I had just written you an email at your QTR address asking about my registration, then I saw your response here. The stars are aligned :) John --- Roy Harrington <roy@...> wrote:
