Backstop is the only commercially available backing material that conforms to the ANS/ISO Standard 5/4 ñ1983, ANSI PH2.17-1985 which outlines conditions to be used for the measurement of press sheets, proofs, and off-press proofs with densitometers. It provides a matte black, flat, firm surface necessary to prevent variation caused by surface irregularities, such as those found when making measurements on a pile of press sheets or other soft surfaces.
