Re: [Digital BW] New icc based Soft-proof profiles for QTR

2004-01-14 by Carl Schofield

I've found a way to strip read the targets.  I used ColorLab to create 
new reference and target files from the original i1 RGB 1.5 reference 
file.  I converted the target tif to LAB-L and then gray (gamma 2.2) as 
before for printing. The new reference file is placed in the reference 
files>printer>eye-one> folder in the ProfileMaker Pro folder so it can 
be accessed by MeasureTool.  The new target tif file has borders around 
the patches and it is easily strip read in MeasureTool.  You need to 
check spectral data in the configuration and then pick the new target 
reference file from the chart pop-up list and specify strips with gaps 
before reading the strips.  The data is saved from MeasureTool as a 
text document and the file is placed in the i1Match measurement 
data>printer folder.  Next, open i1Match, select the radio button "load 
the measured chart" and open the file that was read and saved from 
MeasureTool.  i1Match will then create the profile and it did so 
without errors on my first try.  I've added the new target and 
reference files to the Softproof archive on my filesharing site for 
those that want to try making their own softproof icc profiles with the 
eye-one.
