Andrew,
Thanks for the help. I could not open the RGB-Drift.tif image. I think
the file type got hosed. But I will download Logo ColorLab and reproduce
your values.
I was trying to do this in PS starting with Don Hutcheson's proof
checker, but was getting confused on the various parameters such as
patch size, and how much variance there needed to be between patches for
the EyeOne to sense the differences. Your solution using ColorLab
sounds much better.
My immediate use for this is to try to track the drift of 2 Canon CLC's
that are used at one of the design firms I do a lot of work with. The
designers keep saying that the devices drift severely, but when I use
the profiles I built I get pretty consistent results. When I noticed
that Measure Tool will compare measurement data and give us the delta
E's I figured there had to be an easy way to do this.
In thinking about it more, this might be a good idea for tracking drift
on all types of devices. Just print a target like this when you make the
profile, and then periodically print and measure the target and compare
the readings.
There may be an ideal set of values for the target, but my guess is that
as long as you have a good range you'll get a decent idea about how
consistent the device is.
Thanks again.
