We provide detailed inspection and deep cleaning for your entire UV and UV LED infrastructure. By proactively replacing critical components including UV lamps, reflectors, power supplies, and cooling systems at the end of their lifecycle, we eliminate the risk of sudden machine downtime and resolve uncured ink issues directly on the production line.

Our engineering specialists deliver rapid, precision repairs for conventional UV lamp & UV LED systems, and critical power supplies. We restore full functionality quickly to minimize production bottlenecks and keep your pressroom operating efficiently.

We utilize industry-standard measurement equipment to help print shops maintain strict quality control and sustainably reduce substrate waste.

• UV Intensity & Dose Calibration: We accurately measure both UV intensity and UV dose, fine-tuning the system's power output to perfectly match your specific press operating speeds and unique substrate properties.
• GEW UV Mini Lab Unit Testing: We simulate and analyze the curing performance of specific inks and varnishes in a controlled lab environment. This establishes the exact UV energy baseline required before initiating high-speed, full-scale live production.

• Press Operator Training: We provide practical training on basic UV and UV LED system upkeep, teaching your team how to properly inspect and maintain UV lamps, reflectors, and cooling systems to prolong equipment life.
• Post-Installation Support & Optimization: Our technical consultants troubleshoot workflow bottlenecks and optimize system parameters to match real-world operating environments, ensuring your flexo lines run with maximum continuous efficiency.

We conduct three critical performance tests to guarantee the durability and quality of your printed labels and flexible packaging:

• Lightfastness Testing: We measure UV resistance to prevent color fading when your packaging is exposed to sunlight or retail lighting.
• Coefficient of Friction (COF) Testing: We analyze surface slip and friction values, ensuring your packaging films run smoothly on high-speed Form-Fill-Seal (FFS) lines without jamming or dragging.
• Rub Resistance Testing: We evaluate scuff and abrasion resistance to ensure your printed graphics withstand the physical stress of transit and handling.

We formulate highly accurate ink blends matched directly to Pantone books, physical print samples, or your specific target values. This guarantees absolute color consistency across every production batch and eliminates costly color shifts (ΔE variations) during live press runs.

Our ink and coating specialists deploy directly to your pressroom to diagnose and resolve technical bottlenecks. We troubleshoot critical press-side issues such as color variations, poor ink adhesion, and incomplete curing. By optimizing ink formulations and aligning them exactly with your specific substrates and flexo press parameters, we ensure flawless, continuous production.

• Regional Agility (Polifilm Vietnam): Leveraging Polifilm’s newly established manufacturing facility in Vietnam, we provide the Thai market with significantly faster lead times, an agile supply chain, and rapid on-site support.
• German Engineering & Custom Formulation: Backed directly by polymer and structural film specialists at Polifilm’s headquarters in Germany, we offer advanced technical consultation. We collaborate with your team to engineer and develop customized film formulations tailored to your brand’s exact performance and barrier specifications.

PSG’s field engineers conduct comprehensive press-side diagnostics to resolve critical flexible packaging issues mid-production. We expertly troubleshoot:

• Printability Issues: Poor ink adhesion, color trapping, and surface tension failures.
• Converting & Finishing Flaws: Weak seal integrity, leaking seals, and abnormal film shrinkage during thermal processes.
• Web Handling & Runnability: Extreme Coefficient of Friction (COF) variations that cause the web to stick to rollers or slip uncontrollably on high-speed lines.

To solve these, we fine-tune your machine parameters and tension controls to align perfectly with the specific physical properties of the film, ensuring smooth runnability and peak plant efficiency.

Press Systems Group (PSG) conducts thorough, on-site condition assessments for both narrow web and wide web flexo press across the label and flexible packaging sectors. We proactively detect component wear and tear to prevent press-side material damage, reduce the risk of unplanned downtime, and maintain strict production tolerances:

• Magnetic Cylinders: We inspect for surface wear and dimensional irregularities that could compromise flexible die performance, minimizing the risk of defective die-cutting.
• Flexible Dies: We examine cutting-edge integrity to prevent common converting flaws, such as incomplete cuts, deep cuts that damage the backing liner (liner strikes), and die-cutting misregistration.
• Anilox Rolls: We perform press-side inspections of cell structure integrity and cell volume. We diagnose wear or blockages early to prevent uneven ink transfer and inconsistent color density.
• Doctor Blades: We evaluate blade wear and contact pressure settings to mitigate the risk of critical ink metering issues, such as ink spitting and uneven color distribution. This ensures precise ink laydown right from the initial press startup.

Elevate your production efficiency with our in-depth, press-side root-cause analysis. Our engineering experts deploy directly to your facility to resolve immediate and recurring production bottlenecks across a wide array of print tooling including hot stamping & embossing dies. We act as technical consultants for your operators, fine-tuning machine parameters to perfectly match your specific substrates, thereby guaranteeing flawless, high-speed continuous production without unexpected interruptions.

Emergency Plate Production: In the event of a plate-making equipment breakdown at your facility, PSG provides rapid backup production and delivery of eco-friendly, water-wash flexo plates. We deliver sharp dot reproduction and high-resolution imaging, keeping your label and packaging production lines running without interruption.

We offer high-fidelity digital proofing services to accurately verify color profiles, intricate details, and graphic elements against the actual physical plates. This critical prepress step minimizes risks, reduces make-ready waste, and ensures strict color accuracy before full-scale printing begins.

Our flexo prepress and tooling specialists deploy directly to your pressroom to analyze and resolve technical plate issues during live production. We expertly troubleshoot common flexographic defects such as unsharp image details (dot gain issues), poor ink transfer, and premature plate wear. Furthermore, we guide your press operators in fine-tuning machine parameters to perfectly align with your real-world production conditions, ensuring optimal print quality and extended plate life.

We service the following core printing and converting systems:

• Flexo & Finishing Machinery (Rhyguan): We deliver routine preventative maintenance and precision repairs for Rhyguan flexo presses and finishing machine. From die-cutting and slitting machines to hot stamping and embossing units, we perform precision press calibration to ensure perfect print-to-cut registration and maximum production yield.
• Inline & Offline Print Inspection Systems (Daheng): We provide installation, calibration, and repair services for both standalone offline inspection machines and inline defect-detection cameras integrated directly into flexo presses. These automated vision inspection systems help detect print defects in real time, improve quality control, and reduce the risk of defective labels reaching customers.
• 3D Scanning & Measurement Systems (Troika): Technical support and maintenance for advanced 3D microscopes. We help you accurately measure and verify the cell volume of anilox rolls and the dot structure of flexo plates, ensuring ultimate color consistency and optimal ink transfer.

Beyond basic machinery repairs, our field experts deliver advanced press-side troubleshooting and root-cause analysis. We diagnose production bottlenecks, fine-tune machine parameters, and resolve complex converting issues to keep your pressroom running at maximum continuous efficiency.
