Quality Testing of Samples from Multi-Layer-Printing Process using the Method of Visual Color Assessment

摘要

Components and effects are crucial part of the finishing stage of printing products. The demand for their integration into the finishing processes is continuously increasing in the sector of packaging printing. The project "Limitations of over-printing" was focused on the application process of labels and RFID tags into the printing process. The research viewpoint added to the pre-competitive individuality project Constraints of multi-layer-printing. The research project aims to determine the potential and constraints of the multilayer-printing with focus on the achievable quality of printing when different materials are applied. One part of the project was the development and the performance of a visual test which gives information about the perceived quality by test persons. The intention of this paper is to show the visual color assessment planning and realization. Special attention will be obtained to the two visual test methods of pair comparison and ranking order.
