| Abstract | The objective of this work was to study the printability of paperboard and relate it to the paperboard characteristics. The paperboard samples were used from Thailand, Korea, Japan, Indonesia, and Finland. The testing methods followed the TAPPI and SCAN standards. In this study, the equipment called IGT model A2 was used for determining the picking resistance, oil absorption, printed gloss, and amount of ink transferred tested the printability of paperboard. Some paperboards have good smoothness, but low bending stiffness, and low gloss contrast. The testing has shown that no one paperboard that will be the best in all aspects. Printability of paperboard is dependent with properties of paperboard such as roughness, oil absorption, picking resistance, and glossiness. Amount of ink transfers has very close relationship with the roughness. When the roughness is high, the paperboard will take more ink than others will. For oil absorption, the shorter the stain length, the less ink required to reach the same result as other paperboards. The paperboards are able to tolerate higher picking forces when increasing the printing pressure with constant speed and ink viscosity. Surprisingly, some unprinted gloss of paperboards is low, but when the paperboards are printed the glossiness is higher. Good paperboards will have high gloss contrast (gloss contrast= printed gloss% minus unprinted gloss%). It is important to know the paperboard characteristics before choosing the suitable paperboard for printing. The paperboard sample that gave the best printing results had good smoothness, high gloss contrast, high bending stiffness, low oil absorption, and good evenness of print but low unprinted gloss. |
