In the product development industry, manufacturers use different advanced methods to make their products reliable and safe. Rub resistance test is one of those methods that is used in various industries to evaluate the resistance of a print or coated materials to rubbing or abrasion. The longevity of the printed or coated surface needs to be adequately assessed to ensure its durability and longevity. This article will focus on describing the importance of a Dual rub tester and what is the process.

Working Principle of an Ink Rub Testing

It is quite a straightforward process, where the test specimen is subjected to a repetitive rubbing action to determine how durable the print or coated materials are against abrasion. Here is the step-by-step process –

  1. The sample holder is used to test the specimen. It could be a printed label, packaging materials, or any other coated surface. It is a durability test where the sample is prepared to attach to the sample holder.
  2. In the next stage, rub heads or abrasion heads are equipped with rub materials to stimulate the abrasive action during the process. The operator can control the number of rub cycles, pressure, and other standards.
  3. Now, the rubbing elements are brought into contact with the sample. A rubbing or abrasion action is created by moving back and forth.
  4. After a certain number of rub cycles, the tester analyzes if there is any color transfer, wear, or printing degradation.

Key Significances of Rub Testing

Dual rub tester and its ability to provide accurate information about the durability and quality of a print has made it one of the most inevitable quality-checking tests.

  • Quality Control: Rub testing can help in quality control, ensuring the manufactured product meets the durability standards. Industries like printing, packaging, or textiles swear by this abrasion resistance test for product performance requirements.
  • Product Development: During product development, Dual rub testing is invaluable. This is because engineers or designers can customize the materials and coatings as per the result to determine the best level of durability and productivity.
  • Understanding Specific Standards: Abrasion resistance tests allow the manufacturers to ensure that their products are maintaining the best standards. It is crucial to avoid unwanted legal and reputational issues.
  • Cost Savings: Rub resistance test can be a cost-effective solution in the long run since it helps to avoid subpar materials that may require frequent replacement.
  • Better Customer Experience: A top-quality product naturally attracts positive reviews from users. In the same way, products with super abrasion resistance can be associated with better marketing and enhanced product longevity.


To conclude, Dual rub tester is a vital tool in the printing industry that offers a reliable assessment of abrasion resistance. After knowing the fundamentals of rub testing, it is not hard to say why this unique testing method is an indispensable assessment in quality control and product development. At the end of the day, satisfying customer experience is the key to success in a business. With the help of ink rub testers, the produced materials can be tested to endure real-world conditions that can build brand trust and also reduce environmental impact.
