<< Hi:
Somebody told me, that there are 2 versions of the Colorchecker DC:
Generic, $250.00 and Custom for $ 350.00.
What is different with the Custom? I could not find any info on the
Gretag website.
Thank you, >>
As I understand it, the generic is an average reading for each color from
many charts and the custom gives you the reading for each patch FOR THAT
INDIVIDUAL color chart.
What I would like to know is - is it really worth it?
The custom-measured Colorchecker DC is measured by hand - that's one
of the reasons why it costs $100 more.
As to whether or not it is worth it, I think time will tell. The
batches of targets made so far are probably fairly small so the
difference between averaged readings and custom readings may not be
that big.
I have done some comparisons between the batch-averaged and custom
readings and it seems there is some difference. It seems to be in the
more saturated colors. The largest error I have found was dE 2.3.
Most errors are below 2.0 and the great majority of them are under
1.0 as well.
If these numbers are within your tolerance then you probably do not
need the custom measured target.
