Printing Control

II register control REG-G45-VL is designed to manage the printing register control on rotogravure.



The REG-G45-VLT is the latest longitudinal and transversal register control, which makes use of the new technologies available on the market. The use of microcontroller monitored by a supervisor, improves the characteristics of the machine. In order to adjust the machine to the future requirements, it will not be necessary to modify the existing system, in fact it just needs to update the software.
The operator makes use of the video touch screen or of the membrane keyboard. By means of several windows on the high-resolution monitor, it visualises the parameters of the setting out, as well as the parameters for each printing element. Furthermore it verifies the reading of each colour on a simulator of a digital oscilloscope.
The REG-G45-VLT is composed by peripheral intelligent units with a microprocessor for the control of colour register. Each unit receives the information from the parts of revelation installed on the rotary press, and to each format it supplies simultaneously the orders of correction of the register. It conforms on dynamic situations, reducing wastes due to acceleration, change of bobbin or error in the progressive scale of cylinders.


Encoder Application

Scanning Head Application



  • · Reading of any sort of code or traditional marks, without any colour discrimination for the setting out register.
  • · Sensitivity of correction of 0.01mm with a maximum margin of error of +/- 10mm at a speed of 10-750 m/mm.
  • · It functions mark/mark and mark/cylinder, the operator can chose the mark of reference he wants to make use of. (i.e. 1-2, 2-3, 3-4 or 1-2, 1-3, 1-4).
  • · It searches automatically the marks by means of the reading of a specific code. It doesn't admit any setting out error, in fact it allows an exact reading of the mark.
  • · It inserts the register in automatic mode of a previously set speed. The system stops when there is no reference signal or when the paper is folded or stained, in order to avoid anomalous corrections.
  • · It drives compensators with SLO-SYN or DC motors or reference signal +/- 10 V DC for electrical axes.
  • · It memorises the configuration of 999 different types of job with relating functions of register control, which have been already used.
