Improvement Proposals on ISO/IEC 15775 Test Charts for Copier and Printer Outputs
Abstract:This paper describes current activities of Japanese domestic working group 3 for ISO/IEC JTC1/SC28 in JBMA (Japan Business Machine Makers Association). The International Standard IS0/IEC 15775 “Information technology - Office machines - Method of specifying image reproduction of colour copying machines by analog test charts - Realization and application” was published in December 1999. We have been involved in developing the standard for the last four years. The four digital ISO-test charts are downloadable as PostScript(PS)- and PDF-files from the DIN (Deutsches Institut für Normung) or BAM (Federal Institute for Materials Research and Testing) web sites for production of the test charts. This standard is proposed to extend the application not only to copiers but also to printers, scanners and displays as fast-track DIS 19839-1 to 4 from DIN as the standards for color management testing. We made three kinds of the test charts (analog and digital) basically according to the original standard. Then we improved some parts of test charts based on extensive discussion among our WG3 and the International SC28 members for a better application of the current and future standards. These analog charts are printed by excellent offset lithography. The improvements for each chart are compared with the original standard and the published DIN test charts. The quality of these test charts is pointed out.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
