This artwork was created with the rotogravure technique. Therefore I had to evenly spread out black, wax-like paste on a polished copperplate. Then I scratched away the black paste with a really thin, fine needle. Thereafter the copperplate was etched in a acid bath. The waxed parts keep spared, the scratched parts becomes grooves. Then I washed away the paste and filled the grooves with black print colour paste. Now, the copperplate was ready for printing with a special machine. The heavy drum pressed down the copperplate into an absorbent, humid paper sheet, which soaked up the black colour. And here you see the result.^^
