| 1 | Motorized Reciprocating Rub Tester | A weighted rubbing head moves back and forth over a printed surface at a controlled speed and stroke length. | Load control commonly within ±1–2%; stroke control commonly within ±1%; repeatability is generally high when speed, load, and paper conditioning are controlled. | High. Programmable stroke count, speed, load, and automatic stop functions are commonly available. | Coated and uncoated paper, paperboard, labels, folding cartons, flexible packaging films, and printed sheets. | Often 0.5–2.0 kg; typical stroke 50–150 mm; test count may range from 1 to several thousand cycles. | ASTM D5264; TAPPI T 830; internal packaging and print-quality procedures. | Routine quality control and research where repeatable, programmable testing is required. |
| 2 | Manual Reciprocating Rub Tester | The operator moves a weighted rubbing block over the print for a specified number of strokes. | Load can typically be controlled within ±5%; stroke length and speed depend strongly on the operator, so repeatability is moderate. | Low. Manual stroke counting and visual evaluation are normally required. | Paper, board, printed films, labels, and small laboratory specimens that can be clamped flat. | Commonly 0.5–2.0 kg; stroke length is usually fixed or manually defined. | ASTM D5264-style procedures and customer-specific methods. | Low-volume testing, incoming inspection, training laboratories, and budget-sensitive applications. |
| 3 | Rotary Sutherland-Type Rub Tester | A circular weighted specimen or rubbing surface rotates against a printed sample for a defined number of revolutions. | Rotational speed and cycle count are generally precise; practical repeatability is commonly within 5–10% when specimens and loads are standardized. | Medium to high. Automatic cycle counting and programmable stopping are common; visual scoring is usually manual. | Commercial print, coated paperboard, folding cartons, labels, and packaging graphics. | Frequently around 1.8 kg or another method-defined load; commonly 10, 20, 50, or 100 revolutions. | TAPPI T 830; ASTM D5264-related rub-resistance procedures. | Comparing dry-rub resistance of printed packaging and publication materials. |
| 4 | Crockmeter or Finger-Rub Tester | A small finger-shaped rubbing surface travels over the print to simulate repeated handling or contact transfer. | Mechanical stroke and cycle count can be accurate; visual transfer ratings are operator-dependent. Instrument repeatability is typically moderate to high. | Medium. Motorized motion and cycle counting are available, while staining or transfer assessment is often visual or colorimetric. | Textiles with printed graphics, coated paper, labels, films, and surfaces requiring localized contact testing. | Often approximately 9 N for textile crocking methods; stroke is commonly about 100 mm, depending on the method. | ISO 105-X12; AATCC 8; AATCC 116, where applicable to the substrate. | Evaluating color or ink transfer caused by localized finger-like contact. |
| 5 | Wet-Rub Resistance Tester | The printed surface is rubbed with a wetted pad or standard wet rubbing material to measure ink transfer or print damage. | Fluid volume and load can typically be controlled within ±2–5%; results are sensitive to liquid type, wetting time, and pad condition. | Medium to high. Automated rubbing and cycle counting are common; liquid dosing may be manual or programmable. | Water-based and solvent-based printed paper, board, labels, films, coated packaging, and water-sensitive graphics. | Usually method-specific, commonly 0.5–2.0 kg; liquid may be water, buffer, detergent solution, or another defined reagent. | ISO 2836; ASTM D5264 adaptations; customer-defined wet-rub methods. | Packaging exposed to condensation, moisture, cleaning solutions, or wet handling. |
| 6 | Solvent-Rub Resistance Tester | A printed surface is rubbed with a cloth or pad saturated with a specified solvent to assess ink or coating resistance. | Mechanical parameters can commonly be controlled within ±1–3%; solvent concentration, saturation, evaporation, and pad replacement dominate result variation. | Medium. Motion and cycle count can be automated, while solvent preparation and pad saturation are often manual. | Metal cans, coated metal sheets, plastic films, rigid plastics, varnished surfaces, and industrial print coatings. | Often 0.5–1.0 kg or method-specific; stroke and cycle count vary with the solvent and coating system. | ISO 2836; ASTM D5264 adaptations; coating and industrial-print specifications. | Testing chemical resistance of inks, overprint varnishes, and industrial markings. |
| 7 | Dry-Rub Tester | A dry standard rubbing material is moved across the printed surface under a controlled load. | Load and stroke can commonly be controlled within ±1–3%; repeatability is high when paper roughness, humidity, and rubbing material are consistent. | Medium to high. Motorized operation, preset cycles, and automatic counting are widely used. | Paper, paperboard, labels, films, cartons, and other flat printed substrates. | Commonly 0.5–2.0 kg; 10–100 cycles are frequently used depending on the specification. | ASTM D5264; TAPPI T 830; ISO 2836 dry-contact procedures. | Benchmarking scuffing, offsetting, and dry ink-transfer performance in print production. |
| 8 | Abrasion-Wheel or Taber-Style Tester | A rotating abrasive wheel or pair of wheels applies controlled wear to the printed coating or surface. | Load is commonly controlled within ±1%; wear mass loss or optical change can be measured objectively, but results depend greatly on wheel type and calibration. | High. Automatic rotation, cycle count, vacuum removal, and optional mass or optical analysis are available. | Rigid plastic, metal, coated panels, laminates, floor graphics, and durable industrial print surfaces; less suitable for thin or flexible sheets. | Typical wheel loads range from about 250 g to 1,000 g per wheel, depending on the test method; cycle counts may reach thousands. | ASTM D4060 for abrasion resistance of organic coatings; modified procedures for printed surfaces. | Durable coatings and industrial graphics where wear-through is more important than simple ink transfer. |
| 9 | Linear Abrasion and Scuff Tester | A reciprocating abrasive or elastomer tip produces a controlled linear scuff on the printed surface. | Force and stroke are commonly controlled within ±1–3%; repeatability is high for flat rigid samples and moderate for textured or flexible materials. | High. Programmable speed, stroke, force, and cycle count are usually available. | Rigid packaging, coated boards, plastic parts, laminates, labels, and printed films supported on a flat fixture. | Typically 1–10 N, with stroke lengths around 10–100 mm and speeds selected for the material and method. | ASTM D5264 adaptations; ISO 2836-related print-resistance procedures; internal scuff methods. | Reproducing directional scuffs caused by conveying, stacking, and package handling. |
| 10 | Instrumented Rub Tester with Optical or Color Evaluation | A controlled rubbing sequence is combined with colorimetry, imaging, gloss, or optical-density measurement to quantify print change. | Mechanical repeatability can commonly be within ±1–2%; optical performance depends on instrument geometry, calibration, color difference capability, and surface uniformity. | Very high. Automated rubbing, imaging, color measurement, data logging, pass/fail limits, and report generation are possible. | Flat paper, board, films, labels, coated panels, and printed samples with sufficiently uniform measurement areas. | Method-specific, commonly 0.5–2.0 kg for rubbing; optical measurement may use L*, a*, b*, ΔE, gloss, or density change. | ASTM D5264; ISO 2836; ISO 13655 for graphic-arts measurement conditions, where applicable. | High-volume laboratories requiring objective results, digital traceability, and reduced operator subjectivity. |
