RT4 Rub & Abrasion Tester

The Hanatek Rub & Abrasion Tester (RT4) brings new levels of repeatability and convenience to testing the durability of inks and coatings on any printed material.

Designed by Hanatek to increase the efficiency and repeatability of rub proof testing, 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 for the suitability of finished cartons, films, printed books, magazines and promotional materials.

The Hanatek Rub & Abrasion 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.

Benefits of using the Hanatek RT4


The Hanatek RT4 allows the user to compare the durability of printed cartons, commercial print or proofs of ink and varnish on a vast array of substrates across a wide range of applications.

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.



Touch screen operation ensures quick configuration of test parameters


User-configurable cycle times allow tests be to run unsupervised


Air feed hose to remove fibres and debris which act as abrasive agents


Additional attachments available for abrasion and wet rub tests


Choice of weights to comply with BS3110 methods for measuring rub resistance of print

Method of operation

The 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 affects the results.

After testing, the 2 samples are visually analysed. Pass/fail of each test is determined visually or by further analysis by using a densitometer, glossmeter or spectrophotometer.

Sample template cutter for 50mm and 115mm ø included with instrument. Suitable for low volume testing.

Sample Preparation

  • Upper Sample: The 50mm diameter upper sample is typically cut from a sample of printed material. Select an area for testing; it is usual to test areas that are MOST likely to fail; these include any heavy ink build areas or spot colours.
  • Lower Sample: The lower sample is 115mm in diameter – This can either be another sample of the printed material or white paper to see clearly see the ink transference.

Types of tests/pads

The instrument is supplied as standard with the foam measuring head and pad which is suitable for the face to face (printed surface to printed surface) method of testing described in BS3110 and also the printed surface to reference material such as Mellotex.

Alternative measuring heads/pads are available for conducting:
