METHOD OF PRINTING 3D-MICROOPTIC IMAGES ON PACKAGING SYSTEMS

The invention relates to a method for printing 3D-microoptic images on packaging systems in an inline process comprising providing a substrate, printing a plurality of images on at least part of the first major surface of the substrate, applying a transparent varnish layer on the printed first major surface of the substrate, and forming a plurality of relief features on the outer surface of the varnish layer, wherein the relief-features are micro-lenses. 本发明涉及用于以在线方法在包装系统上印刷3D微光学图像的方法，该方法包括提供基板，在基板的第一主表面的至少一部分上印刷多个图像，在基板的印刷的第一主表面上施加透明清漆层，以及在所述清漆层的外表面上形成多个浮雕特征部，其中所述浮雕特征部为微透镜。
