Xandex announces extended shelf life for DieMark 7824 and 7824T Inks. In response to customer requests for longer shelf life for 7824 series inks, the Xandex chemistry laboratory has performed exhaustive testing over the previous 12 months. The goal of this testing was to determine if 7824 and 7824T inks would perform within specification if the "in cartridge" shelf life was extended to four months instead of the current two month shelf life. The test results indicate that the shelf life of 7824 and 7824T inks can be extended to four months with NO EFFECT on the performance of the inks. Beginning on September 22, 2003, all cartridge configurations manufactured with 7824 and 7824T inks will be labeled with an expiration date extending four months from the date (month) of manufacture. No formula or production process changes are being made to 7824 or 7824T inks. Testing was performed on batches of standard, unaltered 7824 and 7824T ink. No changes were made to the formula or in production process used to manufacture the test ink batches.
