I have two pigmented semi-transparent parts which will be made from different resins by different suppliers. They both need to be visually similar in color and degree of semi-transparency (opacity?). One would be polypropylene 1mm thick and the other would be silicone rubber having three different thicknesses, but at the 1mm thickness should match the appearance of the polypropylene part. The tone of the color (purple) should be easy to specify through a chart such as Pantone (is this standard amongst resin suppliers or is there a better system to use for color specification?). The degree of color saturation or degree of transparency is what I'm struggling to characterize in my drawing for these parts. Is there a standard method for specifying this to suppliers?
Thanks,
Mark
