A method is provided for metering a coating liquid in a processing machine having a metering device including at least one applicator roller and one counter-pressure cylinder that forms a coating nip and that guides the printing substrate, the metering device being operatively connected to a circulation system for circulating the coating liquid including a supply line, a return line, a reservoir and a conveying pump. The method includes the steps of: pre-selecting, on the main regulation device, a first target temperature value for the coating liquid in a first area defined by the circulation system downstream of the temperature-regulation unit and by the coating nip; conveying the coating liquid using the conveying pump in a direction of the coating nip; detecting a first actual temperature value of the coating liquid at the temperature-regulation unit using a first sensor; detecting a second actual temperature value of the coating liquid in the first area using a second sensor; transmitting at least one signal to the main regulation device for each of the first and second temperature values detected; comparing the second actual temperature value to the first target temperature value using the main regulation device; and sending at least one control signal from the main regulation device as a function of the first detected actual temperature value.
