Our engineers inspected each printhead before, during, and after the testing cycle. Before each test a new printhead was installed on each printer, photographed at 100X; and a three-dimensional (topographical) measurement was produced for each new printhead (see FIGURE A and FIGURE B). Our engineers printed 2000 meters of ribbon using a 0%, 50%, and 100% test label (see FIGURE C). After 2000 meters, the printhead was photographed at 100X, a three dimensional (topographical) measurement was produced for each new printhead and analyzed.

The photos you are about to view represent testing after printing 2000 meters of ribbon and before cleaning each printhead. These photos represent the 50% Printed Area portion of each printhead.
