The purpose of this International Standard is to provide a method to determine the ink cartridge photo yield of ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated print heads) for colour photo printing with colour inkjet printers and multi-function devices that contain inkjet printer components. Ink cartridge yields determined on one printer model, paper and cartridge configuration are not applicable to another printer model or cartridge configuration even if the ink jet cartridges used in testing are the same. This International Standard prescribes the following: • the test method that manufacturers, test labs, etc. use to determine ink cartridge photo yield; • the method for determination of declared photo yield values from the test results; and • the appropriate method of describing the photo yield of cartridges in documentation supplied to the consumer by the manufacturer. This International Standard is only intended for the determination of ink cartridge photo yield. No other claims can be made from this testing regarding quality, reliability, etc. This International Standard can be used to determine the yield of any cartridge that is used during the printing of the photo test file defined in ISO/IEC 29103. This International Standard is not for use with printers whose minimum printable size is equal to or greater than A3. This International Standard is not intended to measure the yield of photo printing on paper size larger than 4x6, L or A6. In addition, this International Standard is not for use with industrial printers or point of sale printers. It only applies to desktop printing systems.
