To improve printing results, a printing form can be functionalized and the material transferring behavior can be adjusted. In this work, aflexographic printing form is divided into three different areas: first the elevated, material transferring structures (1); second the rising edgesbetween the printing form substrate and the elevated structures (2); and third the transition area (3) between (1) and (2). These three areasare laser functionalized by inserting a defined micropattern. Subsequently, the printing results are investigated and categorized into groups.The groups indicate which functionalized surfaces (1, 2, and 3) have what kind of influence on the printing result. As part of a low cost andefficient approach to manufacture polymeric optical waveguides, a way is presented to show how the waviness of printed conditioning linescan be reduced significantly by laser functionalizing to improve the quality of the waveguides.
