10、11-09 3Introduction This International Standard provides a set of test pages in a common file format that are used in the testing of cartridge yield for colour toner and colour ink. The focus of this test suite is not for printing of photographs, but is intended to be a sampling of typical consumer

12、dard is to define colour test pages for the measurement of consumable yield. The test page suite includes four “customer” type documents and one “diagnostic” page that is used to determine end of ink or toner consumable life. These pages can be used for electro-photographic, inkjet printers and mult

Most office work flows are RG
21、B and the final PDF files are intended to represent average office enviroments. To make sure that a well defined conversion from CMYK to RGB occurs, the conversion from CMYK to RGB is defined within the PS file. In some cases the internal conversion from CMYK to RGB can result in black elements bein
22、g printed in a composite black instead of black colourant only. For this reason a defined method was established to convert from CMYK to RGB and preserve black only elements. There are three cases that are considered: Case 1: C=Y=M=0; K R=G=B=1.0 - K K is the only colour used, set RGB all to an equa
23、l value. Case 2: C=Y=M R=G=B=1.0 - C C, M and Y are equal (composite black) set RGB all to an equal value. Case 3: C, Y, M & K are all non-zero and not equal - In this case: R = 1.0 min(1.0, C + K) G = 1.0 min(1.0, M + K) B = 1.0 min(1.0, Y + K) This represents the majority of colour conversions. NO
24、TE These colour conversions are simplified for the purpose of clarity in the context of ISO/IEC 24712. These test pages are NOT recommended for use in colour quality evaluations. 6 Page Descriptions Only the PDF versions of the documents will be used for yield testing. The fonts used in the document
