Claim:
A method for controlling or regulating a folder of a printing press, comprising the steps of: printing at least one fold control mark onto a printed copy or a printing material of the printed copy; folding the printed copy or the printing material of the printed copy in the folder, thereby creating at least one actual fold, said step of printing comprising printing at least one fold control mark at least one of before and after each said step of folding, and said step of printing further comprising printing first fold control marks onto the printed copy or the printing material of the printed copy in an unfolded state, and printing second fold control marks onto the printed copy in a partly folded state; after said step of folding, measuring the at least one fold control mark and obtaining at least one fold actual value from the at least one actual fold; comparing the at least one fold actual value with a corresponding fold setpoint value, the corresponding fold setpoint value being associated with one of the at least one fold control mark; and automatically setting an adjusting device of the folder based on the results of said step of comparing the fold actual value to the fold setpoint value, such that the fold actual value in subsequent printed copies corresponds to or is approximated to the fold setpoint value.
