Rub and Abrasion Tester (RT4)
- Predict print performance
- Assess coating & substrate suitability
- Predict print durability
- Improve packaging effectiveness
The Hanatek Ink Rub Tester (Rub & Abrasion Tester) brings new levels of repeatability and convenience to testing the durability of inks and coatings on any printed material.
The instrument is used for testing the scuff, marking and rub resistance of cartons, films and commercial printed material.
This comparative test works by abrading a printed sample against a reference material under known conditions.
The results can be used to identify alternative substrates, better ink and coating formulations or the suitability of finished cartons, films or printed books, magazines and promotional materials.
The Hanatek Ink Rub Tester can be programmed for the required number of cycles, enabling it to be run concurrently with other laboratory tests.
Optional test attachments offer the ability to conduct tests under harsher conditions and can be used to check the solvent resistance or the cure of UV inks.
Rub Tester Operation:
Instrument platen and test head are driven at an identical speed of 1 rev/sec. This creates a very even abrasion between the top surface and the entire area of the larger test sample.
An air hose blows away sample test debris to ensure no additional abrasion from loose ink particles.
After testing, the 2 samples are visually analysed.
Rub Tester Features:
Choice of Measuring heads
The instrument is supplied as standard with the felt measuring head and pad.
This is suitable for the face to face (printed surface to printed surface) method described in BS 3110 and also the printed surface to reference material such a Mellotex.
Alternative measuring heads/pads are available for conducting:
- Abrasion test
This test is to check the through cure of coatings and UV varnish. This test will mimic the effect of transportation on printed material.
- Wet rub test
This test checks for coating resistance to water/solvent
Touch screen operated
Intuitive touch screen operation ensures incredibly quick configuration of test parameters .
Automatic abrasion cycles
The cycle time is pre-programmed allowing the test to run unsupervised
- The instrument is supplied with cutting templates. For faster and safer sample preparation, the Hanatek Universal Sample Cutter is recommended.
This allows for simultaneous cutting of 50mm and 115mm ø samples.

What is Durability and Abrasion Testing?
A laboratory rub proof tester is a tool for comparing the rubbing, scuffing and marking of inks and coatings on commercial print and packaging, it can be used as part of quality control in a production environment or an aid to development in the laboratory.Protective packaging, magazines, commercial documents and promotional material are all printed with inks and coatings which are designed to remain clear, bright and undamaged during the items lifetime.Unfortunately movement during packing, shipping or everyday handling can cause items to mark or scuff. The coatings and substrates used, the cure conditions and the amount of abrasion all effect the severity of this damage.
