The Japan Color Certification System complies with ISO international standards and provides certification based on Japan Color, which is the canonical standard for printing color in sheet-fed offset printing in Japan. The Japan Color Certification System consists of “Offset Process Control Certification,” “Color Matching Accuracy Certification,” “Proofing System Certification,” “Proofing Process Management Certification,” and “Digital Printing Process Control Certification.” Good or bad printed matter has traditionally been determined on the basis of how it looks, and printed matter has been created in the absence of clear standard. In most cases, printing companies respond to demands for color reproduction by clients, designers, etc., by repeated revisions and reprinting. The lack of a canonical standard for creating printed matter and a certifying organization has been the major cause of such a situation. Thus, in order to facilitate the widespread use or adoption of Japan Color and facilitate standardization of printing to avoid unnecessary revisions and reprinting and other relevant purposes, the Japan Color Certification System was established, and is being overseen or managed by a fair third party organization.
