ISO Standards for colour ink jet printers ISO Standards for colour ink jet printers In 2009, the ISO (International Organization for Standardization) published the International Standard for determining the ink cartridge yield for colour inkjet printers and multifunctional devices. This standard is used to prescribe the test method that manufacturers and test labs use to determine ink jet cartridge yields. It also standardizes the appropriate method of describing the yield of cartridges in documentation supplied to the consumer by the manufacturer. Manufacturers of printers or devices that use colour ink jet technology are meant to abide by this standard when testing for, and labeling the estimated yields
