Overview
The Drick DRK150 Ink Absorption Tester is a precision-engineered instrument designed to quantitatively evaluate the ink absorption behavior of paper, board, and coated substrates under controlled conditions. It operates on the principle of timed capillary absorption—measuring the rate and extent of liquid uptake (typically standardized ink or solvent simulants) through porous fibrous structures over defined intervals (e.g., 5 s, 10 s, 30 s, 60 s). This measurement directly correlates with critical print quality parameters including dot gain, ink setting time, gloss uniformity, and potential for set-off or strike-through. The DRK150 complies with fundamental physical testing methodologies referenced in ISO 8791-4 (Paper and board — Determination of absorbency — Part 4: Ink absorption test), TAPPI T 441 (Absorbency of Paper and Paperboard), and GB/T 22893–2008 (Chinese national standard for ink absorption of printing papers). Its robust mechanical architecture ensures repeatability across laboratory, QC, and R&D environments where consistent substrate characterization is essential for press readiness assessment.
Key Features
- Automated timing mechanism with ±0.1 s resolution for precise absorption interval control (5 s, 10 s, 30 s, 60 s selectable)
- Calibrated vertical sample holder with adjustable clamping force to ensure consistent contact pressure and eliminate edge leakage
- Standardized ink reservoir system with gravity-fed delivery and removable, cleanable stainless-steel ink trough
- Integrated digital stopwatch synchronized with actuation trigger for operator-independent start/stop logic
- Modular design enabling rapid calibration verification using certified reference papers and traceable volumetric standards
- Compliance-ready documentation support: calibration certificate included; traceable to national metrology institutes (CNAS-accredited calibration available upon request)
Sample Compatibility & Compliance
The DRK150 accommodates standard sheet specimens measuring 100 mm × 100 mm (or larger, with optional custom holders), supporting uncoated, clay-coated, calcium carbonate-filled, and barrier-coated papers up to 600 g/m² basis weight. It is compatible with both aqueous and low-viscosity solvent-based ink simulants (e.g., ISO 2836-compliant test inks). All mechanical components meet RoHS Directive 2011/65/EU requirements. The instrument’s operational methodology aligns with GLP (Good Laboratory Practice) documentation workflows and supports audit trails required under ISO/IEC 17025:2017 accredited testing laboratories. While not a regulated medical device, its use in pharmaceutical packaging qualification supports ICH Q5E stability protocol development when paired with validated ink systems.
Software & Data Management
The DRK150 is a standalone hardware platform without embedded software or touchscreen interface—intentionally engineered for reliability, minimal maintenance, and long-term calibration stability. All measurements are recorded manually or integrated into existing LIMS/QMS platforms via standardized data entry templates (CSV-compatible). Optional companion software (DRK-DataLink v2.1, sold separately) provides statistical analysis tools—including coefficient of variation (CV%) calculation per batch, trend charting across shifts, and export to Excel or PDF reports compliant with internal QA documentation standards. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when deployed with electronic signature modules and role-based access controls.
Applications
- Pre-press evaluation of paper absorbency profiles prior to offset, flexographic, or gravure printing trials
- QC release testing for coated paper manufacturers verifying consistency against master batch specifications
- Formulation development for inkjet-receptive coatings and barrier layers in flexible packaging substrates
- Root cause analysis of print mottle, poor drying, or ink feathering in production troubleshooting
- Academic research on fiber network porosity, sizing efficiency, and surface energy modification effects
- Supplier qualification audits requiring objective, repeatable substrate performance metrics
FAQ
What ink types are recommended for routine testing?
ISO 2836-standardized test inks (Type A for offset, Type C for gravure) or manufacturer-specified simulant fluids with viscosity ≤15 mPa·s at 23 °C.
Can the DRK150 be used for non-paper substrates such as films or foils?
Yes—when equipped with optional hydrophobic surface adapters and non-wetting ink formulations; validation per ASTM D724 is advised.
Is third-party calibration certification available?
Yes—CNAS-accredited calibration services are offered with full uncertainty budgeting and traceability to NIM (National Institute of Metrology, China).
What maintenance is required for long-term accuracy?
Quarterly verification using certified reference paper sets and annual cleaning of ink pathways with isopropanol; no consumables beyond standard lab-grade solvents.
Does the DRK150 meet international regulatory requirements for pharmaceutical packaging testing?
It supports method development aligned with USP and ISO 11607-1; final method validation remains the responsibility of the end-user’s QA department.
