Study Guide

Objectives

The aim of the course is to create knowledge on the targets and technologies for paper and paper board surface treatment.

After completing the course, the student:
• knows the targets of coating and surface sizing and their requirements on base paper
• identifies the principles of the different paper and paper board coating and surface sizing processes
• knows the raw materials of coating and surface sizing and can select suitable raw materials based on end use requirements
• understands the effect of surface treatment parameters on the product quality, costs and environment and can modify these
• can plan, calculate and make a coating colour formula keeping in mind the targets of coating, printing method requirements and costs
• comprehends the manufacturing processes of different surface treated products
