I think scoring is usually done by rolling a circular (semi blunt) object on paper - much like a pizza cutter, except it is not that sharp.
Creasing is done by folding paper, and pressing it - much like placing an anvil over it.
The effects are probably different - scoring results in cracking (peeling of toner) at the fold.
But, todays finishers might do a better job of scoring and call it creasing; so may be they are defined to be the same.

What would you say is the nature of the difference between 'crease' and 'score'?

>> Hi there,
>> In Finishings 2.0 / 2.1, the "trimming-when" member attribute has 4 keywords defined 'after-documents', 'after-job', 'after-sets', and 'after-sheets'. But what keyword would the user provide if they don't want the paper cut at all?
