Ink Rub Resistance Testing Made Easy with Pacorr's Abrasion Tester

Pacorr understands the critical importance of maintaining the quality of printed materials. One of the essential quality control tests in packaging and printing industries is assessing the ink rub resistance. Pacorr's Ink Rub Resistance Tester is a highly reliable and efficient abrasion testing instrument specifically designed for determining the durability and quality of ink used on various substrates such as paper, cardboard, labels, and packaging materials.

What is Ink Rub Resistance?

Ink rub resistance refers to the ability of printed inks to withstand wear and tear without smudging, smearing, or fading during handling, transportation, and storage. Poor ink rub resistance can negatively impact the appearance and legibility of printed packaging and labels, damaging brand reputation and consumer confidence.

Importance of Testing Ink Rub Resistance

Regularly conducting ink rub resistance tests ensures that printed materials meet industry standards for durability. This testing helps manufacturers identify potential quality issues early, preventing costly product recalls and ensuring consistency in branding and packaging integrity.

Overview of Pacorr’s Abrasion Tester

• Adjustable rubbing speed and cycles
• Precise pressure control
• Compatible with various test materials
• Easy-to-use control interface
• Robust construction ensuring reliable performance

How to Test Ink Rub Resistance Using Abrasion Tester

Testing ink rub resistance with an abrasion tester involves several clear steps to ensure accurate and reproducible results.

Step-by-Step Guide to Perform Ink Rub Resistance Testing

Step 1: Prepare the Samples

Before conducting tests, it is crucial to select representative printed samples. The samples should be conditioned at room temperature (23 ± 2 degrees Celsius) and relative humidity (50 ± 5 percent) for at least 24 hours to standardize the testing environment.

Step 2: Set Up Pacorr’s Abrasion Tester

Set the Pacorr abrasion tester on a stable surface. Adjust the rubbing head, ensuring the selected rubbing pad material (usually standardized white test paper or rubber pad) is securely attached and clean.

Step 3: Place the Test Samples

Carefully mount the sample on the flat testing bed, ensuring it is smooth and securely held in place. The printed side of the material should be facing upwards, exposed to the abrasion pad.

Step 4: Select Test Parameters

Configure the machine settings according to standardized test methods, such as ASTM D5264 or ISO standards, typically specifying rubbing speed, pressure, and number of cycles.

• Speed: Adjust rubbing speed according to standard (usually 42 cycles per minute).
• Pressure: Typically set between 2 to 4 pounds (0.9 to 1.8 kilograms).
• Cycles: Standard cycles can range from 50 to 100 cycles, depending on the industry standard.

Step 5: Conduct the Test

Initiate the abrasion test. The rubbing pad moves back and forth over the sample, replicating friction conditions experienced in real-world applications. Observe the rubbing action carefully to ensure consistent contact throughout testing.

Step 6: Examine the Results

After the designated cycles are complete, remove the sample and inspect it visually. Evaluate the printed material for:

• Smearing or ink transfer to the rubbing pad
• Fading of printed areas
• Overall appearance after rubbing

Step 7: Document and Analyze

Record the test outcomes clearly and compare them against acceptable quality standards. This documentation assists in identifying trends over time, improving quality control, and aiding in preventive measures.
