Thanks Karthik
This is a nice presentation. maybe I missed some information you may have already provided, but would you know how to specify a colour (of pigment or paint) to a moulder of plastic parts? I got the inspection part of using a spectrometer.
In my experience using the pantone shade cards (for print) is not very useful with plastics paints - they never turn out as we imagined them and there is scope for difference in interpretation.
