Abstract

In printing industry, prototyping is necessary to ensure quality reproduction of jobs. Conventional printing processes like gravure cannot be used for prototyping because of high manufacturing cost of gravure cylinders. Such challenges can be successfully tackled by use of relatively cheap and flexible printing processes, such as inkjet. Even though inkjet printing is a cost effective way for prototyping, it has its own limitations, especially in the case of woodgrain printing. Wood-grain patterns need to be printed with a release coating and adhesive. Inkjet printers are incapable of printing release coating and adhesive because release coat and adhesive require certain amount of coat weight, which is not possible with inkjet printing. Inaccurate color reproduction, metamerism and incompatibility with release coat are the commonly seen problems during prototyping. The main aim of study was to resolve problems of metamerism and achieve close color match. A Design of Experiments (DOE) was carried out by using different factors such as gray component replacement (GCR) settings, release coat weight and use of tie coat to analyze its effect on metamerism. Results showed that GCR setting was the most influential factor among all factors.
