| 1 | Motorized dry-rub tester | ASTM D5264; ISO 2836 dry-rub procedures | Approximately 115 mm (4.5 in) | Commonly 0.9 kg or 1.8 kg (2 lb or 4 lb) | Standard white rubbing paper or textile rubbing material | Fixed reciprocating motion; many units operate near 43 cycles/min | Ink transfer, scuffing, gloss change, image damage, and gray-scale rating | Routine quality control for cartons, labels, flexible packaging, and commercial print |
| 2 | Motorized wet-rub tester | ISO 2836 wet-rub methods; laboratory internal procedures | Typically 60–115 mm, depending on the test platform | Adjustable; commonly 0.9–1.8 kg | Water, detergent solution, or another specified liquid applied to the rub medium | Programmable or preset stroke count; controlled liquid application is recommended | Color transfer, ink bleeding, coating lift, and print-image deterioration | Food packaging, beverage labels, paperboard, and products exposed to moisture |
| 3 | Dual-purpose dry-and-wet rub tester | ASTM D5264 and ISO 2836, where the selected setup is compatible | Usually about 100–115 mm | Selectable low and high loads, often 0.9 kg and 1.8 kg | Dry paper, wet paper, textile, or customer-specified rubbing material | Preset speeds commonly ranging from approximately 20 to 85 cycles/min | Comparative rub resistance under dry and liquid-contact conditions | Multi-product laboratories that need one instrument for several print substrates |
| 4 | Manual reciprocating ink-rub tester | Method-specific procedures based on ASTM D5264 or ISO 2836 | Operator-defined; commonly 50–115 mm | Fixed or manually selected, commonly 0.5–2.0 kg | Paper, textile, or other specified rubbing material | Manual stroke count and operator-controlled motion | Pass/fail comparison, visible transfer, smearing, and surface damage | Incoming inspection, small print shops, field checks, and low-throughput testing |
| 5 | Multi-load programmable rub tester | ASTM D5264 or ISO 2836 with documented laboratory settings | Typically 60–115 mm | Several selectable levels, often from 0.5 kg to 2.0 kg | Dry or pre-wetted paper, textile, film, or substrate-specific material | Digital speed, stroke count, and load configuration; repeatable test recipes | Quantified comparison of transfer area, color difference, and failure rate | High-volume quality control, supplier qualification, and process optimization |
| 6 | Crocking-style reciprocal tester | AATCC 8 or ISO 105-X12 for textile-style rubbing evaluation; adapt only when appropriate | Approximately 104 mm in common crocking configurations | Commonly about 0.9 kg for standard crocking evaluation | Standardized white test cloth, dry or wet | Fixed reciprocating stroke with defined rub count, commonly 10 cycles | Color transfer to the white cloth using a gray-scale assessment | Printed textiles, transfer prints, fabric labels, and textile-like surfaces |
| 7 | Instrumented rub tester with optical assessment | ASTM D5264 or ISO 2836, combined with an internal image-analysis method | User-configurable, commonly 60–115 mm | Adjustable according to the selected standard and product specification | Dry or wet standardized rubbing material | Automated speed, stroke count, load monitoring, and test-data recording | Digital image analysis, color difference, density loss, and transferred-area measurement | Research laboratories, global supplier comparison, traceability, and statistical process control |
