PRINT QUALITY COMPARISON OF SOLID BLEACHED SULPHATE (SBS) BOARDAND DUPLEX BOARDPRINTED WITH WEB OFFSET PRESS

Solid Bleached Sulphate Boards (SBS) and Duplex Boards are commonly used substrates for various carton based packaging applications. Both types of boards were printed with Web Offset Printing Press available in local market keeping in target to check printing characteristics i.e. Solid Ink Density, Dot Gain and Print Contrast. A master consisting of quality control patches was prepared, printed and evaluated for above mentioned print characteristics with the help of spectrodensitometer. The results indicated that Solid Bleached Sulphate Boards are better than Duplex boards in terms of Solid Ink Density and Dot Gain. On the other hand, Duplex boards are better than in term ofPrint Contrast.
