Methods and systems for setting the pressure of the cylinders of the printing press without requiring special targets

A method for setting the pressure of a printing station, including at least one cylinder, of a printing press, from acquired images of the printed area of the printed web, the method comprising the procedures of:

• displacing said at least one cylinder of said printing press in accordance with a pre-defined displacement scheme, and acquiring said acquired images of the web throughout the displacement of said at least one cylinder;
• for each of said at least one cylinder, determining according to said acquired images, a left side print distance, at which said printing station prints, at a predetermined sufficient print quality, on the left side of said printed area, and a right side print distance, at which said printing station prints, at a predetermined sufficient print quality, on the right side of said printed area;
• and
• determining for said each of said at least one cylinder a left actuator working distance and a right actuator working distance for the left actuator and the right actuator, respectively, of said each of said at least one cylinder, according to said left side print distance and according to said right side print distance.
