20、15(E)IntroductionThe purpose of this International Standard is to provide a process for determining the ink cartridge yield for a given colour inkjet print system (i.e. integrated ink cartridges and ink cartridges without integrated printheads) using a standard consumer type test suite. In the case

21、where a cartridge set can be used in multiple printer models, only one yield test needs to be performed as long as the difference between printer models does not impact yield.NOTE A cartridge supplier may choose to use more than one market identifier for a single physical cartridge. In this case, on

22、ly one yield test is required as long as there are no differences in the cartridges other than market identifiers.This International Standard prescribes the following: the test method that manufacturers, test laboratories, etc. use to determine ink cartridge yield; the method for determination of de

23、clared yield values from the test results; and the appropriate method of describing the yield of cartridges in documentation supplied to the consumer by the manufacturer.The cartridge yield is determined by an end-of-life judgement, or signalled with either of two phenomena: fade, caused by depletio

24、n of ink in the cartridge, or automatic printing stop, caused by an ink out detection function. It is envisioned that one of the uses of this International Standard will be for the calculation of cost per page (CPP). While this International Standard measures a portion of this cost, it is not used a

25、s the sole component of CPP calculation. Additional factors are considered for CPP calculations.

26、components1 ScopeThe scope of this International Standard is limited to evaluation of ink cartridge page yield for ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated printheads) for colour inkjet print systems. This International Standard can also be appl

27、ied to the printer component of any multifunctional device that has a digital input printing path, including multi-function devices that contain inkjet printer components. Both liquid and solid ink products can be tested using this International Standard.This International Standard is only intended

28、for the measurement of ink cartridge page yield when printing on plain paper. No other claims can be made from this testing regarding quality, reliability, etc.This International Standard can be used to measure the yield of any cartridge that is used in a significant amount during the printing of th

29、e test suite defined in ISO/IEC 24712.This International Standard is not for use with printers whose minimum printable size is equal to or greater than A3 or for printers designed or configured to print photos (for example, maximum printable size less than A4 or a printer configuration intended for

30、photo-only printing). In addition, it only applies to drop-on-demand printing systems.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For u

32、r colour printing with inkjet printers and multi-function devices that contain inkjet printer components3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1fadephenomenon in which a significant reduction in uniformity occurs due to ink depletionNote

33、 1 to entry: In this test, fade is defined by a significant increase in lightness, L*, or a decrease in density on the bands surrounding the edge of the last page in the test page suite (Diagnostic Page). This decrease in density does not have to occur completely across the page. This comparison is

34、made using the second diagnostic test page generated during testing (the 10th page printed). For examples of fade, please consult Annex A.INTERNATIONAL STANDARD ISO/IEC 24711:2015(E) ISO/IEC 2015 All rights reserved 1BS ISO/IEC 24711:2015ISO/IEC 24711:2015(E)Note 2 to entry: In some printer systems,

35、 fade can occur prematurely due to the way that ink is provided to the printing system. If a printer exhibits fade, a five minute pause is allowed to provide for recovery of the ink delivery system and printing can continue. If fade appears on the next suite, then the cartridge is judged at end of l

36、ife and the additional diagnostic page printed is not counted in the yield calculation. If fade does not appear on the next diagnostic page, then printing can continue until the next fade or ink out is encountered and the additional diagnostic pages will be counted.3.2streaksvery thin lines of colou

37、r, other than intended in the bands surrounding the edge of the last page in the test page suite (Diagnostic Page)Note 1 to entry: Streaks differ from fade in the width and severity of increase in lightness, L*, or reduction in density. Streaks can appear for a number of reasons, thermal issues and

38、clogged nozzles being two of the main causes. If these streaks occur in three consecutive diagnostic pages, then a streak removal operation is required. Comparisons are made using the phenomena sample provided in Annex B.3.3streak removal operationprocedure used to restore the print performance by r

39、emoving streaksNote 1 to entry: If streaks are observed on three consecutive diagnostic pages, first the printer can be left idle for five minutes. Then an additional three test suites are printed. If the streaks are still observed, then a streak removal operation is conducted according to the lates

40、t printer manufacturer documentation. Due to the significant amount of ink that is used for cleaning, the maximum permissible number of times that the streak removal operation can be used on a given cartridge is prescribed in 5.2.1.Note 2 to entry: All test page suites printed during this process wi

41、ll be included in the page count for determining the yield.3.4printhead alignment operationfunction that aligns newly installed printheadsNote 1 to entry: If it is mandatory according to the latest printer manufacturer documentation, this operation is performed during testing. The pages used in the

42、alignment procedure are not counted in the measurement of yield.3.5ink lowwarning generated by the printing system when it has determined that the amount of ink is such that a cartridge change may be required soonNote 1 to entry: It does not indicate that the system is out of ink.3.6ink outsignal ge

43、nerated by the printing system when the useable ink in the system is depleted and the printer stops printing3.7end of lifecondition determined by one of two mechanisms: fade (3.1) or ink out (3.6)Note 1 to entry: For cartridges with more than one colour of ink in a single cartridge, end of life is d

44、efined when the first colour within the cartridge exhibits fade or ink out. In the event that the printer can continue printing after ink out is reported, the cartridge will still be considered at end of life.3.8test page suiteseries of five pages defined in ISO/IEC 24712 that are printed consecutiv

46、on and end of life (3.7) and multiplying by fiveNote 1 to entry: If the printer stops due to ink out in the middle of a test page suite, the number of the diagnostic pages printed is counted. Then, the first diagnostic page of the remaining print job is included in the subsequent cartridge yield.Not

47、e 2 to entry: The number of test page suites counted may contain some pages that show visible fade. To simplify the testing, determination of end of life is only made on the diagnostic page (last page of the ISO/IEC 24712 test page suite).3.10declared cartridge yieldat or below the lower 90 % confid
