Abstract
A medium, typically a fluid, is supplied at a level of a rotatable body and is dispensed by a dispenser, such as a spray dispenser. The spray dispenser includes at least one spraying nozzle which applies a dampening agent to the roller. A spraying frequency of the spraying nozzle is adjusted with respect to a rotation frequency of the roller that is receiving the dampening agent. This makes it possible to avoid superposition of the dampening agent, at least for a defined number of rotations of the roller receiving the dampening agent.

A method for setting a correlation between a duration of a period of a spray dampening unit and a duration of a revolution of a cylinder including:
- providing a spray dampening unit having at least one spray nozzle and adapted to deliver a dampening agent in discontinuous flow amounts;
- operating said spray dampening unit over a period with a duration and within which said dampening fluid is delivered;
- including in said duration of said period, over which said spray dampening unit is operating, a spray nozzle delivery time and a spray nozzle off-time;
- providing a cylinder having a circumference receiving said dampening agent from said spray dampening unit during said period in which said spray dampening unit is in operation;
- determining a characteristic of said cylinder;
- setting said duration of said period over which said spray dampening unit is operating in accordance with said cylinder characteristic;
- and
- applying said dampening agent to said cylinder in accordance with said setting for applying said dampening agent to said cylinder circumference in a complete dosage and starting at a same location on said circumference no earlier than at each third successive revolution of said cylinder.
A method for setting a spraying frequency of a spray dampening unit including:
- providing at least one spray nozzle;
- using said at least one spray nozzle for spraying a dampening agent;
- providing a roller;
- using said at least one spraying nozzle for applying said dampening agent to said roller;
- determining a characteristic of said roller;
- setting a spraying frequency of said spray nozzle as a function of said roller characteristic for avoiding overlaying of said sprayed-on dampening agent, at least for a defined number of subsequent rotations of said roller receiving said dampening agent;
- and
- selecting said defined number of subsequent rotations being at least two.
