Testing Scuff Resistance of Newspaper Ink

News is the beginning of our day. They keep us aware, increase knowledge and help us connect well with our nation and the world. It also helps people know about the trend, advertisement, new product, new offers etc. Although with TV news channels, and digital news applications, the trend of print media is vanishing with time, however, many people still prefer newspapers over digital media. Due to this, the newspaper manufacturing industry and newspaper ink manufacturers are still in the business. And to remain there, one must deliver the best quality. Let’s see how Scuff Resistance Tester can help a newspaper ink manufacturer to be ahead of the line.

How does quality matter in newspapers? And what factors are to be taken care of?

It is often noticed that print quality differs in various papers. And also the quality differs even from page to page. Sometimes, it is noticed that the front page quality is better than the middle section. Also, some national level newspapers have better quality than those which are circulated locally. So this is how the quality varies and the major difference that is noticed is the print quality, the newspaper ink.

To sustain the printed ink quality, one must assure that the newspaper ink is tough enough to resist all kinds of external forces experienced by the newspaper bundles. The major factors which are responsible to disturb the ink quality are the scuffing forces experienced by papers at the production line, storage and during distribution. This happens when the newspaper surface is scrubbed against other newspapers or machine rollers while in the production unit. If the ink quality is poor it might get blurred or it may get erased after scuffing. Therefore, it’s important to evaluate the quality of print ink quality before its use.

How can we evaluate the newspaper ink quality?

To test the ink properties beforehand we must observe how the ink after being used on paper will perform when placed in a similar scuffing situation. And to keep standardisation we must use a system that delivers the same criteria every time it is used. Scuff Resistance Tester, is used to check the quality of paint, coating, printing ink etc. against constant scuffing or rubbing forces.

The machine is equipped with a firm sample holder, where we can keep the sample newspaper with the specimen ink on it. The sample is clamped properly using safety pins so that the sample itself doesn't produce any movement. This ensures fewer chances of error development in test values. The tester deliver uniform and the same scuffing forces using a upper weight circular clamp that is rubbed against the sample in a defined speed for a defined time and rotations. The machine is designed as per international test standards and is renowned to deliver unmatched precision in quality inspection.
