Advanced printing and packaging technologies request improvements in resolution and quality as well as in environmental sustainability due to applications for functional surfaces, security printing and advertising. The conventional laser-based production of such tools is subjected to melting effects causing strongly limited results and cost-intensive post processing. Hence, ultra-short laser pulses were used for engraving that can reduce or eliminate those problems. However, high power 1064 nm ps-laser sources must be combined with high speed scanning to avoid heat accumulation and particles shielding. Finally two applications are presented to demonstrate the possibilities of laser engraving. The first shows the production of high quality intaglio printing plates. Here not only the plates but also the printing results are investigated. The second application is the production of laser-induced periodic surface structure (LIPSS). This ripple structures can be produced in short time on large scale cylinders and the distinct optical diffraction effect of the resultant structures can be used for different applications.
