More Information
Summary:The invention relates to a device for curing UV inks on a substrate, comprising a plurality of radiators (12) designed as UV-LED radiation sources (12). The device comprises a plurality M2 of optical elements (15) which are designed and arranged in such a way that the respective maximum emission angle [alpha] max of the radiator is limited to [alpha] max < = 30 DEG. The invention is advantageous in that undesired matting effects are reduced or even prevented. 本发明涉及一种用于使承印材料上的UV油墨硬化的设备，包括复数M1个构造成UV-LED辐射源的辐射器(12)。所述设备包括复数M2个光学元件(15)，所述光学元件这样构造和布置，使得所述辐射器的相应的最大发射角αmax限制成αmax≦30°。本发明以有利的方式实现，减少或者甚至防止非期望的消光效应。
