Services
Pad Printing
Our pad printing services handle complex multicolor images on curved, flat, and irregular surfaces with tight registration. Using open well and sealed cup technology, we achieve gradients and halftones on materials like ABS, polycarbonate, and medical-grade plastics. Automation capabilities support high-volume production while maintaining ISO 9001:2015 quality standards for industries ranging from automotive to pharmaceuticals.
Screen Printing
We provide single and multicolor screen printing for large opaque images on rigid substrates. Our UV and conventional inks deliver durable prints on glass bottles, metal panels, and plastic components. Custom tooling ensures precise color registration for cylindrical and flat parts, serving industries requiring high-visibility branding on products like cosmetic containers and electronic housings.
Hot Stamping
Our hot stamping process applies reflective and holographic foils to plastic, wood, and leather surfaces without requiring pretreatment for polypropylene materials. Contoured dies enable decoration of raised text and compound curves, ideal for automotive trim and cosmetic packaging. Automation options maintain consistency for high-volume production runs.
Digital Inkjet Printing
This direct-to-substrate digital inkjet process handles four-color process plus white ink for plastic, glass, and metal substrates. We achieve photographic quality prints with precise color matching for prototyping and medium-volume production. The technology eliminates traditional plate-making requirements while maintaining durability for promotional and consumer goods applications.
Surface Treatment
Our plasma and flame treating services prepare low-surface-energy plastics for optimal ink adhesion. Custom equipment handles flat polypropylene caps and cylindrical polyethylene bottles while maintaining material integrity. Post-treatment verification ensures long-term print durability for health and beauty industry packaging subjected to frequent handling and environmental exposure.
