Claims7
A method of reducing the cut-off length of a newspaper, the method comprising:
- providing a press unit having at least one existing plate cylinder, each of said existing plate cylinders having two existing plates attached thereto, each of said existing plates comprising generally half a circumference of the attached existing plate cylinder, said plate cylinders being thus configured to print two pages of a newspaper with each rotation;
- and
- replacing all said existing plate cylinders with new plate cylinders having generally the same length, diameter, and circumferences as the existing plate cylinders without modification to the frame of the press unit, said new plate cylinders having a single new plate attached thereto, each of said new plates comprising generally the entire circumference of the attached new plate cylinder
- configuring each of said new plate cylinders to print three pages of a newspaper, said three pages arranged about the circumference of said new plate cylinders such that each of said three pages comprises generally one-third of the circumference of said new plate cylinder.
