22 DLS Development at Janoschka Kippenheim The Year 2000: beginning of the DLS development The Year 2005: DLS in high quality on the market The Year 2010: 5 DLS systems in our global network Installation of the 6 th DLS system in rgentina Page 22

23 Performance Gravure Speed: 35,000 or 70,000 cells/s Effective Range of Screen: L/cm (Single Shot and Master Screen) Effective Resolution used: L/cm 03. November 2010 Different Types of Laser in Packaging User Report Page 23 Single Shot Master Screen

24 Cell Geometry Single Shot vs Master Screen Single Shot Screen equals resolution Very fast engraving Only round cells possible Variation in cell types conventional, halfautotypical and superhalfautotypical Cell depth up to 35µm ( in one pass ) ( Multi pass possible ) Page 24

25 Cell Geometry Single Shot vs Master Screen Master Screen Resolution higher than screen ( similar to image setter ) Hexagonal cell Variation in cell types conventional, halfautotypical Outline possible Cell depth up to 35µm ( in one pass ) ( Multi pass possible ) Page 25
