valtorta st/e - the printing machine suitable for the reproduction of wood, marble or decorative designs on MDF panels, hardboard panels, veneer, PVC, or on plastic materials. The application process is based on the offset indirect printing; the steel photoengraved roller transfers the pattern onto the rubber coated application roller, which prints it on the workpiece. The printing can be with one, two or three colours, according to the requested pattern. The individual printing heads work in perfect synchronization, combining the different colours for a very natural result. In case of multi-colour printing, each machine is linked to the others by means of an electronic control, which controls and synchronizes the different drives of each machine.
Advantages:
High mechanical precision thanks to: - drives controlled by brushless motors, head height adjustment on high precision linear guides, - adjustment of the doctor roller and application roller nip on high precision linear guides.
High precision printing thanks to the precise electronic control with: - high definition electronic longitudinal phase adjustment, possible with machine in operation, - very precise pattern synchronization, which enables the printing of geomatrical drawings and half tones, - storage of the electronic cylinder phase adjustment with possibility of selecting the pre-stored pattern number,- user-friendly error diagnostics,- possibility of working with reground rubber application rollers with different diameters one to the other.
