Tuairisgeul Bathar:
Gnìomhachas Thoraidhean Qualtech Professional Automatic Ink Rub Tester is a professional Automatic Sutherland Type Ink Rub Resistance Test System to instantly test and determine the Ink Rub Resistance of printed samples at the touch of a button.
In high-volume printing, packaging manufacturing and industrial surface coating, surface durability dictates product quality. Whether assessing printed folding cartons, protective laminates, or light-sensitive layers on photosensitive (PS) offset plates, poor ink adhesion leads to costly product returns, customer complaints, and material waste.
An Professional Automatic Ink Rub Tester QPI-ART6800 provides quality assurance teams, print engineers, coating chemists, and materials research scientists with an automated, highly repeatable standard for evaluating dry rub, wet rub, and abrasion resistance. As a high-accuracy Precision Ink Rub Tester, the QPI-ART6800 transforms qualitative surface inspection into precise, quantifiable data by simulating real-world scuffing during transport, handling, and processing.
Technical Overview & Operating Principle
Seo Precision Ink Rub Tester measures rub abrasion resistance by subjecting a test specimen to controlled surface-to-surface friction. The test specimen is clamped flat on the instrument base, while a standardized receptor medium (typically 80 g/m² clean coated paper, cut to a 50 mm width) is secured to a weighted rubbing head.
During the test cycle of this professional Automatic Ink Rub Tester, the motorized rubbing block moves back and forth across the specimen at a user-defined speed, stroke distance, and pressure load. Upon cycle completion, operators analyze surface degradation through two primary standard methods:
Optical Density Decrement: Measuring the loss of color or ink concentration using a densitometer before and after the test.
Coating Thickness Decrement: Evaluating mass loss or physical film erosion across the contact zone.
By standardizing load, speed, and contact geometry, the QPI-ART6800 eliminates operator bias and provides consistent comparative metrics across production batches.
Key Industry Applications
1. Packaging & Commercial Printing Quality Control
Unprotected ink layers on folding cartons, flexible packaging, and corrugated containers are highly vulnerable to scuffing during transit.

Automatic Ink Rub Tester QPI-ART6800 – Application:
In commercial printing, packaging engineering, and industrial surface coatings, physical durability is as vital as optical appearance. A printed package or coated substrate must endure significant mechanical stress—including friction, scuffing, and rubbing—during transit, automated handling, and end-use. When ink layers fail, products suffer visual degradation, barcode unreadability, and premature rejection.
To evaluate surface adhesion and abrasion resistance under controlled laboratory conditions, materials scientists and quality assurance engineers rely on standardized test methods established by ASTM Eadar-nàiseanta agus an International Organization for Standardization (ISO). Utilizing modern laboratory instrumentation—such as the Professional Automatic Ink Rub Tester QPI-ART6800 no an Precision Automatic Ink Rub Tester QPI-ART6800—allows engineering teams to implement standardized rub abrasion resistance testing, optimize curing processes, and eliminate product failure.
The Core Physics of Ink Rub Resistance Testing
Ink rub testing measures the mechanical cohesive strength of an ink or coating film and its adhesive bond to an underlying substrate (such as paperboard, flexible film, or metal foil). Advanced instruments like the Precision Automatic Ink Rub Tester QPI-ART6800 automate this process by exposing specimens to controlled friction under defined parameters:
Contact Pressure: Standardized weights apply uniform normal force across the specimen surface.
Relative Motion: Motorized rubbing heads execute planar back-and-forth strokes at precise, controlled speeds.
Receptor Medium: Standardized receptor materials (such as unprinted 80 g/m² coated paper or specified felt) capture transferred ink.
After completing a prescribed number of test cycles on the Professional Automatic Ink Rub Tester QPI-ART6800, scientists evaluate specimen degradation using optical density measurements (densitometry), mass loss, or quantitative surface analysis.
Primary ASTM Standards for Abrasion & Rub Resistance
ASTM International provides several widely recognized procedures for assessing ink layer falling-off, scuffing, and coating wear.
1. ASTM F1571: Standard Test Method for Determination of Abrasion and Smudge Resistance ASTM F1571 focuses on evaluating the smudge and abrasion resistance of printed images produced by business copy products, inkjet systems, and thermal transfer printers. The Precision Automatic Ink Rub Tester QPI-ART6800 provides the constant load application and precise cycle control required by this standard to quantify ink transfer accurately.
2. ASTM D5264: Standard Practice for Abrasion Resistance of Printed Materials by the Sutherland Rub Tester ASTM D5264 is the primary benchmark for the packaging and converting industry. Commonly referred to as the Sutherland Rub Test, this procedure uses a motor-driven stroke mechanism with specific weight attachments. Modern laboratories utilize the Professional Automatic Ink Rub Tester QPI-ART6800 to execute these standardized testing protocols:
Dry Rub Testing: Evaluating dry ink scuffing under ambient room conditions.
Wet Rub Testing: Assessing moisture sensitivity by dampening the receptor medium.
Wet Bleed & Transfer: Testing ink solubility and transfer when exposed to water or chemical agents.
3. ASTM D4060: Standard Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser While ASTM D5264 covers printed paperboard and flexible substrates, ASTM D4060 applies to rigid coated panels, protective varnishes, and industrial laminates. Using rotary rub action with abrasive wheels, this method measures mass loss per thousand cycles (mg/1,000 cycles) or wear index.
ISO Standards for Printing Inks and Graphic Technology
International engineering teams and global supply chains frequently mandate adherence to ISO standardization to maintain uniform quality across manufacturing facilities.
1. ISO 18947: Graphic Technology – Imaging Materials – Rub Resistance of Prints ISO 18947 specifies standardized methods for determining the rub resistance of photographic prints, digital press outputs, and traditional printed media. High-accuracy systems like the Precision Automatic Ink Rub Tester QPI-ART6800 allow operators to strictly follow ISO guidelines for test speed, load stability, and ambient temperature control.
2. ISO 2836: Graphic Technology – Prints and Printing Inks – Assessment of Resistance to Various Agents ISO 2836 focuses on testing chemical and physical resistance. It governs how printed substrates react when subjected to physical friction in the presence of specific liquid agents, including water, solvents, oils, detergents, and food stimulants.
Key Test Parameters and Engineering Controls
To achieve high repeatability and cross-laboratory correlation when implementing ASTM and ISO rub resistance protocols, engineering teams must standardize critical parameters:
Normal Load (Force): Dictates contact stress across the ink interface. Implemented via standard 10 N ± 0.1 N primary load with additional weights.
Rubbing Velocity: Influences frictional heating and surface shear forces. Implemented via stepless variable speed regulation from 5 to 95 cycles/min.
Receptor Medium: Affects the coefficient of friction and ink absorption. Accommodates standard 80 g/m² clean reference paper (50 mm width).
Environmental Control: Relative humidity alters paperboard moisture and ink flexibility. Controlled via precise touchscreen setup within climate-controlled lab environments.
Practical Best Practices for QA Laboratories
Precision Sample Preparation: Always cut test specimens cleanly using a dedicated sample cutter to prevent frayed paper edges from skewing frictional force readings.
Receptor Material Consistency: Replace the standard receptor paper strip after every single test run to prevent cross-contamination and debris buildup.
Quantitative Data Collection: Utilize the Professional Automatic Ink Rub Tester QPI-ART6800 alongside reflection densitometers or spectrophotometers to measure optical density loss (ΔD) before and after rub testing.
By integrating established ASTM and ISO standards with high-precision equipment like the Precision Automatic Ink Rub Tester QPI-ART6800, packaging engineers and materials scientists can objectively verify surface durability, reduce material waste, and safeguard product quality across global distribution channels.
