UV‑printed Products

A: Non-porous materials like stainless steel, glass, and anodized aluminum require chemical bonding agents and elevated surface energy. We clear surface oils with isopropyl alcohol, apply flame or plasma treatment to achieve surface energy above 44–48 dynes/cm, and apply a substrate-specific silane primer before jetting ink. This process creates a covalent bond between the ink matrix and the substrate, ensuring prints consistently achieve a 4B/5B rating on ASTM D3359 cross-hatch adhesion tests.

A: Hard UV inks cure into a dense, cross-linked polymer matrix that provides superior pencil hardness (2H–4H) and maximum chemical resistance against industrial solvents like MEK. They are recommended for rigid metal plates, acrylic signage, and glass displays. Flexible UV inks contain elastomeric monomers that allow up to 180% elongation without micro-fracturing. They are required for flexible membrane overlays, TPU cases, or components that undergo post-print die-cutting, embossing, or bending.

A: Yes. We create custom ICC color profiles for each substrate-ink combination using X-Rite spectrophotometers aligned with G7 color standards. Production passes are monitored to maintain Delta E values below 1.5 against approved master proofs. For strict corporate branding or industrial color specs, we log colorimetric data for every batch to ensure accurate matching on reorders months or years later.

A: We do not rely on manual alignment for pre-cut or complex components. We machine custom aluminum or high-density tooling jigs on CNC routers using your CAD files (.DXF/.STEP). These jigs incorporate stainless steel locating pins and vacuum hold-down channels, locking component placement tolerances within ±0.1 mm across the entire flatbed workspace.

A: Artwork should be submitted in vector format (.AI, .EPS, or layered .PDF). Standard CMYK graphics should be placed on one layer, while white ink backing layers, spot clear coats, and raised 3D texture paths must be placed on separate vector layers labeled "Spot_White" or "Spot_Varnish". Vector strokes must maintain a minimum width of 0.25 pt to ensure crisp edge definition during multi-pass ink stacking.

A: Silk-screen printing requires physical screen creation and film setups, making short runs or multi-color graphics with fine gradients expensive and slow to produce. UV flatbed printing eliminates screen setup costs, prints full-color photography and variable data (such as sequential serial numbers or 2D barcodes) in a single pass, and cures instantly under LED lamps. While silk-screen may offer lower unit costs for simple 1-color prints on runs exceeding 20,000 units, UV printing provides significantly faster turnaround times and lower total cost for multi-color, precision industrial parts.
