To score or not to score? This question faces anyone creating a printed piece that must be folded before mailing, display, or delivery. While in some cases folding without scoring will be sufficient, in others, scoring eliminates any color cracking on the fold and can make all the difference in producing an elegant final result.
The top consideration in whether or not to score a printed piece is the thickness of the paper being used for the project. As a general rule, paper that is 100 lbs. or heavier should be scored before folding. Other instances where scoring the paper is recommended would include:
A steel rule is formed in the desired shape and braced in wood affixed to a metal frame. Paper is then pushed between the steel form and the press.
