Torrey Pines Research: Latest Inkjet Print Test Results Released

By: by Steven Beyer, VP Business Development, Torrey Pines Research


August 2007: Fairport, NY: Torrey Pines Research (TPR) is publishing the results of its latest tests that studied image stability and relative longevity of inkjet printer products.  The results of these tests, which were conducted at their private imaging and development laboratories, were released in July, and full reports are available.

Consumers want to know that their images, photo prints, will last without worry or having to provide any kind of special protection.  As observed in the TPR study, there is a significant variation in performance of the tested inkjet printing systems under the three test conditions used.  Ten inkjet printing systems by Canon, Dell, Epson, Hewlett-Packard, Kodak and Lexmark were tested.  The new Kodak EASYSHARE 5300 printers were among those tested and finished with the best overall rating of the 10 systems evaluated.

The test was commissioned by the Eastman Kodak Company.  Over a period of approximately nine months, TPR subjected the image samples to a battery of high-intensity light fade, accelerated gas-fastness or pollution simulation testing, and elevated humidity and temperature conditions.  A summary of the test conditions, process, and conclusions reached in the analysis by TPR can be found at the company website ( under the "Publications" heading.

TPR has been testing printers and printing technology products since its inception in 1986, and conducting Image Permanence tests since 2000.  Although to date there is no industry standard test methodology, TPR has applied commonly used methods and procedures for accelerated exposure under several conditions that have been shown to affect image stability.  An upcoming paper on Image Permanence will be presented by TPR's CTO, Peter Mason, at the Imaging Science and Technology Conference in September.  The material will discuss results of image longevity and stability tests that will also include consumer-grade laser prints in addition to inkjet and other traditional photographic systems and media.
