Red River ink life testing

Following up on our recent post concerning ink cartridge life, Red River Paper, one of our favorite paper companies, has posted some similar test results regarding Epson’s Stylus Photo R1900 and Stylus Photo R2400 printers. They used the same test image and similar measurement techniques to come up with a cost per print for images printed at 4" by 6", 5" by 7", 8" by 10", 11" by 14" and 13" by 19". They also work a bit deeper on trying to define a metric for something they call “Cartridge Equivalent Usage,” or CEU.

This report addresses concerns and arguments about the true cost of ink in desktop photo printing. Using the Epson R2400 and Epson R1900, we conducted a series of print tests to determine how much ink is used in a full coverage 8”x10” print. From that figure we extrapolated ink usage per square inch. The objective is to share a realistic cost per print vision with inkjet users. The choice to pursue photo inkjet printing is in the end an individual economic choice.

We think this is pretty important stuff, and it’s good to see others working on similar tests — the data regarding the R1900 is especially welcome, and it looks like Red River’s results on the R2400 are very similar to ours, which speaks well to this style of test’s repeatability. If you’re interested in this topic, it’s worth going through the report.

Based on some of the comments we’ve received, we think there are a few tweaks we can make to get the test methodology a bit more secure, and be extended to HP and Canon printers. Stay tuned.
