IGT C1/C1-Orange/G1-5/F1 Printing Printability Tester

Overview

The IGT Printing Printability Tester series—comprising the C1, C1-Orange, G1-5, and F1 models—is a precision-engineered benchtop system designed to replicate key mechanical and rheological conditions of industrial printing processes under controlled laboratory conditions. Developed in the Netherlands and widely adopted across global R&D labs and quality control departments, these instruments operate on the fundamental principle of simulating ink transfer mechanics via defined nip geometry, metered ink film deposition, and calibrated pressure–speed–dwell time parameters. Unlike full-scale press trials, the IGT platform enables rapid, repeatable evaluation of printability using minimal substrate and ink volumes—typically less than 0.5 mL of ink and standard A4-sized substrates. Each model is purpose-built for a specific printing technology: the C1 for offset lithography (including UV-curable systems), the C1-Orange as a cost-optimized variant for routine offset ink screening, the G1-5 for gravure ink characterization, and the F1 for flexographic and gravure dual-mode validation. All units comply with internationally referenced test methodologies including ISO 2836 (graphic technology — ink transfer), ISO 12647-3 (process control for offset), ASTM D4679 (gravure ink transfer), and TAPPI TIP 0404-01 (flexo ink performance).

Key Features

• Modular design with interchangeable printing units: rubber-covered or photopolymer plates for offset; engraved gravure cylinders (standard 60–200 LPI); anilox rollers (available in 300–1200 LPI, ceramic or chrome-plated steel) for flexo mode.
• Precisely adjustable parameters: printing speed (0.1–1.5 m/s), nip pressure (0–500 N), ink dwell time (0.1–10 s), and roller temperature (ambient to 60 °C optional).
• Integrated ink metering system with oscillating ductor roller and doctor blade assembly ensuring uniform ink film thickness (±2 µm reproducibility) across repeated runs.
• Low-mass printing disk (<20 g) compatible with analytical balances for gravimetric ink film thickness measurement per ISO 2836-2.
• Motorized, programmable control interface supporting multi-step test sequences, parameter logging, and real-time torque monitoring during impression.
• Compliance-ready architecture: audit trail capability, user-level access control, and electronic signature support for FDA 21 CFR Part 11 and EU Annex 11 environments upon software configuration.

Sample Compatibility & Compliance

The IGT series accommodates a broad range of substrates—from uncoated and coated papers (60–350 g/m²), cardboard, and corrugated board (including single- and double-wall fluting) to plastic films (PET, PP, PE), metallic foils, and UV-curable coatings. Ink compatibility spans conventional mineral-oil-based offset inks, energy-curable (UV/EB) formulations, water-based and solvent-based flexo inks, and low-viscosity gravure inks (10–500 mPa·s). All models are referenced in national standards such as DIN 16524 (Germany), NF Q30-004 (France), and JIS P8138 (Japan), and serve as primary reference equipment in accredited laboratories operating under ISO/IEC 17025:2017. Test reports generated meet GLP documentation requirements when used with validated SOPs and calibrated traceable standards.

Software & Data Management

IGT instruments integrate with the optional IGT TestSuite™ v4.x software—a Windows-based application supporting method creation, automated test execution, and statistical analysis of print density (via integrated spectrodensitometer interface), dot gain, trapping efficiency, drying time (by sequential tack measurement), and ink rub resistance (ASTM D5264). Raw data export is available in CSV, XML, and PDF formats. The software supports version-controlled method libraries, instrument calibration history tracking, and compliance with FDA 21 CFR Part 11 through electronic signatures, audit trails, and role-based permissions. Data integrity is ensured via automatic timestamping, checksum verification, and secure local database storage with optional network backup.

Applications

• Pre-press validation of ink–substrate interaction for color matching and process window definition.
• Routine QC of incoming paper/board batches for surface energy, absorbency, and coating uniformity.
• Development and benchmarking of new ink formulations (e.g., low-VOC, bio-based, or high-gloss UV inks).
• Troubleshooting print defects—including mottling, picking, scumming, and poor trapping—by isolating variable contributions (pressure vs. speed vs. dwell time).
• Supporting supplier qualification audits and customer technical service reports with standardized, reproducible data.
• Educational use in graphic arts curricula for teaching ink rheology, transfer physics, and process–property relationships.

FAQ

What distinguishes the IGT C1 from the C1-Orange model?

The C1 features full programmability, higher torque capacity, and support for UV-curable inks with optional thermal control; the C1-Orange is a streamlined variant optimized for manual operation and basic offset ink screening in production environments.
Can the F1 model validate ink performance on corrugated board?

Yes—when equipped with low-pressure anilox rollers and compliant elastomeric impression rollers, the F1 reproduces flexo transfer behavior on flute profiles up to B-flute, per TAPPI TIP 0404-01 guidelines.
Is calibration certification included with delivery?

Each unit ships with a factory-issued calibration certificate traceable to NIST and EURAMET standards; annual recalibration services are available through authorized service centers.
How does the IGT system ensure repeatability across laboratories?

Through strict adherence to ISO 2836-defined geometric tolerances (e.g., roller parallelism ±5 µm, surface roughness Ra <0.2 µm), documented maintenance protocols, and inter-laboratory round-robin validation programs coordinated by IGT BV.
Are replacement parts and consumables readily available?

All critical components—including engraved gravure cylinders, anilox rollers, rubber blankets, and doctor blades—are stocked globally and supplied with batch-specific dimensional certificates.
