Fellow Color Freaks!!
We have a client that wants us to output a chart on it that shows a
very particular color they want to match [...]
The product has many different plastics and fabrics, from
many different manufacturers, and they are having trouble expressing how
close this color needs to be. [...]
Just an additional note: take care of metamerism failures! If you have
different materials and no controlled viewing conditions, the chart may
be useless as visual reference. I have no clue of material testing, but
I know for example that plastics and solvent inks exhibit a completely
different behavior in different lighting conditions than paper and
offset inks.
Once again: If you just want to illustrate differences, I think there is
no problem. If you need a visual reference, there are many.
