1.1This test method describes a procedure for measuring reflection density of printed matter using a reflection densitometer or spectrodensitometer.

1.2This test method is intended primarily for process colors (yellow, magenta and cyan) and black. With appropriate instrumentation, it may also be used for other colors.

1.3This test method applies to prints made by any printing process on a flat surface, with reflection density values ranging from just above zero, on the unprinted substrate, through to around 2.5 for very dense prints.

1.4This test method can be used for prints on paper, film or board but not for those on metal or foil. It can be conducted in the pressroom or laboratory.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
