Rub and Color Transfer Testing Crockmeter 418

The Crockmeter 418 is a reliable, easy-to-use instrument designed to measure how much color transfers from one surface to another due to rubbing. Whether you're testing textiles, prints, or coatings, this rub tester delivers consistent, repeatable results.

What is the Crockmeter 418?

The Crockmeter 418 (also known as the crockmeter 418 TABER) is a straightforward mechanical device used primarily for Rub and Color Transfer Testing. It’s commonly applied to:

• Textile testing – Measure color transfer from fabrics to other materials.
• Print durability – Assess smear or smudge resistance in printer/copier outputs.
• Paints and coatings – Evaluate gloss changes caused by rubbing, scuffing, or marring.

How It Works

Using the Crockmeter 418 is simple:

1. Clamp your test sample to the instrument base.

2. Attach a standard square of crocking cloth to a 16mm acrylic rubbing finger.

3. The finger applies a pressure of 900 grams and moves in a straight 100mm path with each stroke of the arm.

4. After the test, compare the stained crocking cloth against the AATCC Gray Scale or Chromatic Transference Scale.

5. Assign a grade based on the amount of color transfer.

This method ensures a standardized and repeatable evaluation process.
