STUDY OF SURFACE STRUCTURE OF INDIAN PRINTING PAPERS

Abstract

Printing is the' most fundamental end use of paper. During printing process there are number of variables affecting the printability of paper like type of paper, type of ink, type of printing process and condition of press. The behaviour of paper in a printing process is of prime concern to the paper maker. Although large number of paper properties control the runnability and printability of paper, the Smoothness of paper surface plays a vital role for good print quality. In the present study, the surface patterns of different papers are studied by actual printing of paper by partial coverage area method. A brief review of the relevant literature is presented in Chapter 2. The description of the experimental• set up and experimental procedure are given in Chapter - 3. The results of the present study and a discussion on the results is presented in Chapter 4. A number of ways to -clraracterize 8- grades of printing papers have been attempted and' the values of various parameters are reported. The -important conclusion of the study and recommendation for future work are given in Chapter '5.
