The mentioned mattifying unit includes lower rolls that allow the glass to be carried throughout the mattifying unit and top rolls that give directionality for printing. Therefore, abrasions and deformations occur on the surface of the glass which is conveyed by the mentioned rolls and simultaneously printed by a matte finish. This causes receiving defective products from the production line and the productivity loss in production.

As a result, the existence of the above problems and the inadequacy of existing solutions necessitated an improvement in the relevant technical field.
