Profile Maker Averaging

[magma]

Hallo everyone,

I am kind of new at this (Profile Maker 5.0) but I was trying to create a profile using ECI2002CMYKi1A3 as a reference point and what I measured when I printed it out as measurement data. Everything went ok. But then I tried to be smart so I printed out a whole lot of sheets, started measuring at random (top of stack, middle of stack, end of stack), averaged my measurement data and now... what do I compare them with? Why can't I create a profile having ECI2002CMYKi1A3 as reference data and the average of what I measured as measurement data?

Anyone?

The measure tool from Profile Maker 5 has an averaging function.

For best results when reading the data, it should be saved as ProfileMaker, not CGATS

Thank you for the reply Michael :-)

I am using the averaging function from the Measure Tool. I add the measured data (let's say 3 files) and it prompts me to save their average. Problem is that the file it saves contains all patches (from all 3 measurements) so I cannot use it as a comparison to the reference file (which only contains the reference data once) in order to create a profile.

I must be doing something wrong, but I don't know what...

I think you might be confused as to what "reference data" means. Reference data in ProfileMaker is simply the device CMYK values that you're printing....there are no measurements in the reference data file, only CMYK values.

What I would do is...

* Measure as many of the charts as you can or have time for and save each as Measure-1, Measure-2, etc.

* Average them all together using the Measure Tool Average function and save this as a new measurement data set called "Average" (creative, huh?)

* Open the Average data set and all the individual data sets in Measure Tool that you used to create the average.

* Using the Measure Tool Compare function, select the Average data on the left side as the "reference" and then compare that (on the right) to each individual measurement.....note the "Worst 10%" delta E values and look if there are any samples that appear noticeably higher than the others. If you see any, note what measurement # it is and *re-average* all the data sets again...but excluding any of the "outlier" data sets. The end result should be an averaged data set that represents the "best" or most consistent of all the individual data sets. Use that to make your final profile.

Wow! Thanks a lot Terry :-)

It might have taken me a century to finish but it worked like a charm!

Million Zillion Thanks
