STUDYING THE EFFICIENCY OF INK RECEPTIVE MATERIALS IN LITHOGRAPH PRINTING ON ALUMINUM PLATES

Abstract

The study aimed to investigate the efficiency of printing ink receptive materials in the lithograph printing process on aluminum printing plates, with the following objectives: 1) Study the properties of printing ink receptive materials by creating printing plates in the lithography. 2) Test and compare the efficiency of printing ink receptive materials with red lacquer in creating printing plate images in the lithography process. 3) Evaluate and analyze the efficiency of printing ink receptive materials with ingredients from Thailand to reduce costs and provide alternatives for creating lithograph printing plate images in Thailand. The research was qualitative and involved the following steps: 1) Study the production of printing ink receptive materials with local ingredients to find suitable properties by comparing their efficiency with red lacquer in the lithography process. 2) Develop tools for analyzing and comparing the efficiency of printing ink receptive materials with red lacquer in the lithography process. 3) Verify the efficiency of printing ink receptive materials in the lithography process using questionnaire analysis and content analysis from comparative print results. 4) Collect data from tools to conduct comparative analysis of the efficiency of printing ink receptive materials with red lacquer in the lithography process. The research findings were as follows: 1) Printing ink receptive materials served as a base for ink absorption from the rollers, increasing the ink quantity for printing plates. They also strengthened printing plates in thin areas and resisted acid erosion. Furthermore, the ingredients were locally available and odorless during use. 2) Printing ink receptive materials were as efficient as red lacquer and performed well with all types of printing plate equipment. 3) The evaluation and analysis confirmed that printing ink receptive materials with local ingredients were efficient for creating printing plates, comparable to red lacquer in the lithograph printing process. This suitability and usefulness can contribute to the practical creation of aluminum printing plates in the lithography process.
