Comparative Test: Eleven multifunction printers: Light resistance
Our lab tests, how much color prints on photo-paper bleach out when exposed to light. To accomplish that, we use the checking device "Atlas Suntest XLS+". The prints are exposed to its xenon-lamp for 72 hours.
Comparing the "before" and "after" pictures you will see the difference between prints generated with dye-ink or pigmented ink. The latter have considerably less problems with bleaching.
Both Epson printers and the Kodak AIO are using pigmented ink. The rest utilizes dye-ink. The heaviest bleaching can be found with Lexmark´s printer.
The test is done on photo-paper the manufacturer recommends.
