This structure is the result of the experience gained both on mechanical engraving and on anti-wear coatings used in the gas and oil fields and also for corrugated cardboard.
The same manufacturing process of Deltor T is used, but the galvanic chrome-plating of the roll is replaced by coatings with anti-wear properties.
This specific product is mainly used in those applications where the kind of screen does not allow the use of laser beams (screens from 5 to 20 l/cm).
The possible configurations are listed in the technical data sheets for mechanical engravings.
