Re: [Digital BW] Bill Atkinson's Target Reference Files

2005-12-09 by Steve Kale

Actually it's simpler than that.  I took a flyer and tried it - reading 128
rows of patches is not a lot of fun.  I wouldn't dream of offering a
profiling service without an EyeOne IO.

Use MeasureTool to read the chart and then load it in Match for the
compilation to an ICC profile. (You need to change the reference file name
you are using to one expected by Match.)  All the observations are there in
the profile.  Big profile though:  1.7MB.  (GM have confirmed that Match
uses the same algorithms as PM5 at its "default settings".)

FYI Colorlab (povided free but unsupported by GM) is great for making new
targets if you ever have to.

(FYI the limitation is on the number of rows so making a new target with 27
patches wide would exacerbate the issue.  And I'm sure there is no
limitation on developing targets and distributing them - just the profiles
made from them.)
