Abstract
A method for cleaning a printing fluid off a surface of at least one rotatable component of a printing press includes selecting and executing one of a plurality of predefined cleaning operations in an automated way. The selection is made on the basis of a predefined mathematical model executed on a computer and, when the model is executed, a parameter corresponding to an amount of the printing fluid present on the surface is calculated. The improved cleaning method may be applied in all modes of operation of the printing press and in particular allows detergent, cleaning cloth, and/or water to be saved.
Claims8
A method for cleaning a printing fluid off a surface of at least one rotatable component of a printing press, the method comprising the following steps:
- automatically selecting and executing one of a plurality of predefined cleaning operations by using a computer;
- making the selection on a basis of a predefined mathematical model executed on the computer;
- calculating a parameter corresponding to an amount of the printing fluid being present on the surface when executing the predefined mathematical model, the parameter being a film thickness of the printing fluid;
- and
- using the predefined mathematical model to factor in predefined transfer rates of the printing fluid between at least two rotatable components when calculating the parameter.
