Gravure process for printing adjacent color surfaces with various color coating thicknesses
摘要：
A data medium having a printed image is created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.
摘要（中）：

具有打印图像的数据介质通过凹版印刷处理产生。 印刷图像具有至少一个具有第一油墨层厚度的第一油墨区域和具有与第一油墨区域相邻的第二油墨层厚度的至少一个第二油墨区域，使得油墨层厚度不同。 第一和第二墨水区域被用肉眼检查时看不见的尖锐边界线分开，并且两个墨区域的墨层厚度在边界线的区域中通过最小。
