Customised ink-receptive and adhesive coatings for print substrates. We formulate materials that behave precisely the way you need them to.
Applied R&D Material Design
We build reliability into your materials. Through laboratory development, custom formulation, machine trials, and quality validation, we bridge the gap between a technical specification and a dependable product that performs consistently in every print and application.
Outcome: Materials that perform exactly as intended from initial concept to commercial scale.
Versatile Roll-to-Roll Coating
Every coating behaves differently. G3S selects the most appropriate roll-to-roll coating process for the substrate, coating chemistry, and required finished performance—ensuring materials up to 1550 mm wide are coated efficiently and to specification.
Capabilities: Reverse Gravure, Meyer Rod, transfer, and direct coating techniques, with wet-application thicknesses from 5 to 120 microns.
Functional Surface Science
Advanced aqueous chemistry. From pressure-sensitive microsphere systems to high-opacity blockout topcoats, G3S develops bespoke, water-based coating systems engineered to modify how materials bond, protect, and perform in challenging, high-demand applications.
Capabilities: Aqueous polyacrylate and polyurethane chemistries, heat-activated adhesives, microsphere systems, and TiO2-filled grey blockout coatings.
Print-Receptive Surfaces
We ensure your substrates are fully compatible with today’s leading print technologies. Coating performance can be developed and optimised for Inkjet (dye & pigment), UV, Latex, Eco-Solvent, Indigo, and Laser printing systems.
Result: Reliable, waste-reducing print performance across complex graphics and specialised labelstocks.
G3S Group: Bespoke Print Material Coating
From initial laboratory concept to fully validated commercial production, we ensure your custom-coated substrates perform precisely as intended.
G3S combines over 30 years of material science and coating chemistry expertise with precision roll-to-roll liquid coating capabilities to deliver bespoke surface solutions. By mastering water-based coating chemistries and advanced multi-zone drying controls, we modify how your films, papers, and foils bond, print, and protect—giving you a stable, predictable, and highly repeatable supply chain.
Compatible Substrates
Papers, films, foils, and specialised multi-layered constructions.
Application Freedom: Create custom substrates, including PVC-free graphics and bespoke labelstocks, without juggling multiple material vendors.
Maximum Coating Width
Web widths up to 1550 mm.
Commercial Conversion: Perfectly matched to standard wide-format graphic and industrial printing dimensions to maximise material yield.
Coating Technologies
Reverse Gravure, Meyer Rod, transfer, and direct coating. Oscillating Kadant doctoring system for defect-free laydown. Wet thicknesses from 5 to 120 microns.
Flawless Laydown: Active doctoring combined with precision mechanics eliminates physical coating streak defects and ensures uniform thickness across the entire web run.
Coating Chemistry
Sustainable aqueous (water-based) chemistries including polyacrylate, polyurethane, pressure-sensitive, heat-activated, and microsphere systems.
Regulatory-Compliant Performance: Delivers high-performance adhesion or functional properties using water-based chemistry, bypassing solvent restrictions.
Surface Performance
Inkjet (dye/pigment), UV, Latex, Eco-Solvent, Indigo, and Laser-receptive topcoats. High-opacity blockout (TiO2-filled grey) systems.
Vibrant, Waste-Free Printing: Surfaces formulated for specific ink carriers, preventing bleed and ensuring absolute adhesion during high-speed printing.
Process Control
Three-zone indirect gas-fired drying with in-line Teknek web cleaning.
Contamination-Free Stability: In-line cleaning removes micro-dust before the liquid hits the web, while multi-zone drying precisely controls moisture evaporation to prevent cracking, curling, or blistering.
Roll Capacity
Maximum unwind/rewind Ø 1000 mm.
Longer Runs, Less Downtime: High-diameter capacity means fewer roll changes on your finishing machinery, keeping your high-speed production lines moving continuously.
Product Development
Full Concept-to-Scale Pipeline: Laboratory formulation, prototyping, pilot machine trials, and bulk QC validation.
De-Risked Commercial Scaling: We test in a controlled environment first, ensuring your bulk commercial orders work perfectly on day one.
Laboratory & QC Validation
In-house laboratory performance testing certified to international FINAT standards (FTM 1 & FTM 2 Peel Adhesion, FTM 9 Loop Tack) for all self-adhesive and pressure-sensitive formulations.
Adhesion Validation: Standardised FINAT testing provides verifiable proof of initial grab, long-term bond strength, and clean removability before full-scale commercial roll conversion.
Industry Experience
Graphics (floor/wall vinyl, pop-up media), integrated business forms, contract coating, and custom industrial applications.
A Proven Blueprint: We apply over three decades of operational knowledge from highly regulated and demanding sectors directly to your product.
Quality Management
ISO 9001:2015: Continuous improvement operational framework backed by certified quality management systems.
Consistency: ISO-certified processes deliver batch-to-batch repeatability, full material traceability, and continuous quality audits across every production run.
