Pressbox (Press Release) -
It is common to see printings on paper or paperboard in daily life such as paper box, paper carton, books, magazines, labels, calendars and name cards, etc. The printing quality are mainly determined by several factors including printing process, quality of ink, smoothness and features of paper or paperboard. The features of paper or paperboard that may influence the printing quality include smoothness, ink absorbency, elasticity, surface strength and water content of the paper or paperboard.
Abrasion resistance of ink layer is one important parameter that is used to evaluate the printing quality. If the abrasion resistance of the ink layeris poor, the printed words on the paper or paperboard may become illegible and the part with printed area may be abraded in transportation, storage or in use. As a result, the printed words will be not able to be read by the customers, which cause inconvenience or misunderstanding and thus the product image would be compromised. Therefore, it is necessary for the manufacturers to test the abrasion resistance of the ink layer on the paper or paperboard before use.
This article provides a test method of abrasion resistance of ink layer on paper and paperboard for your reference. The testing instrument we used is Labthink’s MCJ-01A Rub Tester. The specimens we used are paperboards with printed words.
The tests are performed according to the following procedures.
Cut one piece of specimen from the provided sample and then fix the specimen in the test plane of the instrument. The size of the specimen should be 230mm×50mm.
Use a reflection densitometer to measure the density of the ink layer on the surface of the specimen.
Fix the rubber pad on the test block and then place it onto the specimen.
Set rub times and then start tests. The rubber pad with test block will rub on the specimen surface until the preset rub times are completed.
When tests are finished, the density of ink layer will be measured by reflection densitometer and the abrasion resistance of the specimen will be calculated.
