Description of parts

[Magnus Forsberg]

And according to the definition, the p stands for the printing, whereby the printing includes the colour of the individual parts and not just the printing itself. The only exception here is colour 16, which stands as a placeholder for every colour.

I think it's wrong here to say "p stands for the printing".The word to use here is "pattern".
The pattern might be made by a mix of differently coloured parts, and printing.
Like the minifig torsos with dual moulded, and printed arms.
