Printing process using rotogravure engraved cylinders. The cylinder is placed inside the ink tray and by means of scapping, excess inks fromengraved cylinders is limited to the desired ink grammage that will be transferred to the printing films. The print quality is superior than Flexographics printing method and the cylinder life is longer than the flexographic printing method. It is good for long runs and highly critical jobs with complex designs (i.e, color separation, vanishing effect). The print quality is more detailed because of higher number of screen lines.
Both Rotogravure and Flexographics printing can be run using surface and reverse printing methods. The following materials are commonly used for this kind of printing:
11. PVC Metallized 12. LDPE – Low Density Polyethylene 13. LDPE White 14. LLDPE – Linear Low Density Polypropylene 15. HDPE – High Density Polyethylene 16. MDPE – Medium Density Polyethylene 17. ONy – Bi-Axially Oriented Nylon 18. CNy – Cast Nylon 19. and, other film materials
