Abstract:Based on the process control technology of offset printing on coated paperboard and industry standard setting, the scope, main content and key technical indicators of the industry standard were determined firstly. Then the performance parameters of three types of typical coated paperboard were tested and the proofs for offset printing on typical coated paperboard were tested. Finally the performance parameters and process control technical specifications of offset printing on three types of typical coated paperboard were analyzed to determine the standard requirements for coated paperboard printing process control. Typical coated cardboard performance parameters were as follows: mass-per-area 170~450 g/m2, CIE whiteness 65~110, gloss 30%~60%, coordinates [95, 1, 0], with CIELAB coordinates of the process color solids(Black[16, 0, 1], Cyan [55, -37, -49], Magenta[50, 74, -2], Yellow[89, -4, 92]). Typical white back coated folding board performance parameters were as follows: mass-per-area 200~450 g/m2, CIE whiteness 90~110, gloss 30%~60%, coordinates[91, 1, -4], with CIELAB coordinates of the process color solids(Black [16, 0, 1], Cyan[53, -34, -50], Magenta[47, 71, -3], Yellow[85, -5, 88]). Typical grey back coated folding board performance parameters were as follows: mass-per-area 200~450 g/m2, CIE whiteness 80~110, gloss 30%~60%, coordinates[90, 1, -3], with CIELAB coordinates of the process color solids(Black[17, 0, 1], Cyan[53, -34, -50], Magenta[47, 72, -2], Yellow[85, -5, 87]). Coated paperboard and coated paper differed much in printing performance parameters, colors and printability. Industry standard setting based on the printability of coated paperboard was of more practical guiding significance to the packaging and printing enterprises.
