Method of controlling inking units in case of printing speed changes

摘要

A method controls a printing speed and a temperature of a printing press to attain a predetermined actuating variable. The printing press includes a control computer. The method is characterized by calculating a target temperature to attain the predetermined actuating variable at a desired printing speed and initiating the adjustment operations to attain the target temperature by the control computer. The actual printing speed is changed via a first acceleration within a tolerance limit with respect to fluctuations about the predetermined actuating variable. The first acceleration process is stopped if the desired printing speed is attained in the process. The first acceleration is changed if the tolerance limits are reached and the desired printing speed has not been attained yet. The printing speed is ran at a modified second acceleration along the tolerance limits until the desired printing speed is attained.

1. A method of controlling a printing speed and a temperature of a printing press to attain a predetermined actuating variable, the printing press having a control computer, which comprises the steps of:
calculating a target temperature to attain the predetermined actuating variable at a desired printing speed; initiating adjusting operations to attain the target temperature by means of the control computer, the adjusting operations including:
changing an actual printing speed via a first acceleration within tolerance limits relating to fluctuations about the predetermined actuating variable;stopping the first acceleration if the desired printing speed is reached;changing the first acceleration if a tolerance limit is reached and the desired printing speed has not yet been attained; andrunning the printing speed along the tolerance limits at a modified second acceleration until the desired printing speed is reached.
