Note that "trapping" has two meanings in the printing world. One relates to the way the inks stick to what it's being printed over :- ie. if one plate printed on paper achieves 100% trap (coverage), then when it's printed on top of a previous plate it might have 90% trap because it doesn't stick as well to ink as paper, etc. The other relates to "choke and spread", used to create plate alignment (registration) tolerance.
