Our DNP laboratories value the importance of relevant and verifiable data. Our backcoat study, conducted in Japan and the United States, continues this commitment to evaluation excellence that has made DNP laboratories worldwide respected.
It is also our belief to respect our competitors and their anonymity; therefore we will not disclose, on this website, any information pertaining to the manufacturer of each competing ribbon tested.
OUR ENGINEERS USED THE FOLLOWING TEST STANDARDS AND METHODS:
Tested Printers:
- Datamax I-Class 4206
- Intermec Easy Coder 4420
- Sato CL-408e
- Zebra 140xiIII
Tested Substrate:
- Fasson® Trans-Therm® IC-Coated paper
Tested Ribbons:
- DNP W137 Premium Plus Wax
- Competitor A
- Competitor B
- Competitor C
Test Equipment: Microscope/Camera: Tokyo Seimitsu 1400D-3DF-12
Test Procedure: Our engineers inspected each printhead before, during, and after the testing cycle.
Before: Before each test a new printhead was installed on each printer, photographed at 100X, and then produced a three dimensional (topographical) measurement of the new printhead.
During: Our engineers printed 2000 meters of ribbon using a 0%, 50%, and 100% test label. After 2000 meters, the printhead was photographed at 100X and analyzed.
After: The tested printhead was then cleaned, using IPA, photographed and a three dimensional (topographical) measurement was taken. The printhead was then set aside for further evaluation. This test was performed, in total, 16 times.
