screen printing

When a shopper checks the time, your dial is the stage where legibility, brand color fidelity, and finish quality all perform together. Choosing the right printing method is the difference between a clock that looks premium for years—and one that fades, peels, or simply feels “off.” This guide breaks down the leading dial-printing techniques, where each shines, and how to pick the best fit for your retail brand. Common Dial Substrates (What we print on) Paper insert (with lens): Cost-effective, great for mass retail. ABS/PS plastic dial: Durable, easy to assemble, accepts many inks. Glass dial (back-printed): Premium, scratch resistant; needs proper adhesion. Aluminum dial: High-end, excellent dimensional stability and heat resistance. Wood veneer/MDF: Warm, natural look; benefits from sealing/clear coats. 1) Screen Printing (Silkscreen) Best for: Solid spot colors, bold numerals/markers, high durability on plastic, glass, or metal.How it works: Ink is pushed through a stencil (screen) onto the dial; one screen per color.Pros Strong, opaque spot colors (including Pantone, metallics, fluorescents). Excellent outdoor/UV durability with the right inks and topcoat. Economical at medium–large runs.Cons Each color adds setup time and cost; large gradients/photographic images are harder.Pro tips Keep hairlines ≥ 0.3–0.4 mm for clean numerals. Use registration marks and color trapping for multi-color dials. 2) UV Flatbed Printing (Direct-to-Substrate) Best for: Short runs, variable artwork, photo/gradient dials, textured effects.How it works: CMYK (often CMYK+White+Varnish) inks cure instantly under UV.Pros Prints directly on plastic, glass (with adhesion promoter), metal, wood. White ink allows vivid prints on dark/translucent materials. Add spot varnish or subtle texture for premium detail.Cons Adhesion depends on pre-treatment; edges need proper cure.Pro tips Request an adhesion/cross-hatch test on your actual substrate. For glass, specify back-print + white flood + protective clear. 3) Offset Lithography (for Paper Dials) Best for: Very high volumes with photographic complexity and tight unit costs.How it works: High-resolution CMYK on coated paper, then laminated or varnished.Pros Sharp detail at low per-unit cost for large orders. Consistent color across runs with proper proofing.Cons Paper insert requires moisture/UV protection to avoid warping/fading.Pro tips Add matte anti-glare film for legibility under bright lights. Specify UV-resistant inks for window displays. 4) Pad Printing (Tampo) Best for: Small logos, indices, or icons on curved/recessed areas (bezels, domed parts).How it works: A silicone pad transfers ink from an etched plate to the part.Pros Excellent on complex shapes and small areas.Cons Not ideal for full-surface dial coverage or large gradients.Pro tips Great companion to screen printing: screen the dial, pad-print a metallic logo. 5) Dye-Sublimation (on Polymer-Coated Aluminum/MDF) Best for: Photo-quality, edge-to-edge prints on metal or MDF with rich color depth.How it works: Ink is heat-transferred into a special coating, becoming part of the surface.Pros Smooth, continuous tones; very resistant to scratching/peeling.Cons Whites come from the coating, not ink—no metallics, and deep blacks may skew warm if not profiled.Pro tips Calibrate carefully; request a hard proof on your exact coated panel. 6) Hot Foil Stamping (Metallic & Specialty Effects) Best for: Premium metallic numerals/indices, logos, rings.How it works: Heat + pressure bond metallic or pigment foil via a custom die.Pros True metallic brilliance; high perceived value.Cons Requires tooling; tight alignment needed with printed artwork.Pro tips Combine with screen print for base graphics, then foil the key accents. 7) Hydrographics (Water-Transfer Printing) Best for: All-over patterns (marble, carbon fiber, wood-grain) on dials or bezels.How it works: Pattern floats on water; part is dipped so the film wraps around.Pros Seamless wrap on 3D forms.Cons Requires clearcoat for durability; pattern registration to numerals is tricky.Pro tips Use hydrographics for the bezel/case, then screen-print a clear, high-contrast dial. 8) Decal / Waterslide Transfers (Then Clearcoated) Best for: Low-MOQ premium marks on glass or metal; intricate crests.How it works: Printed decals are applied and sealed with a protective clear.Pros Fine details without heavy tooling costs.Cons Added process steps; requires careful clearcoating to protect edges.Pro tips Ideal for limited editions or boutique runs. 9) Laser Marking / Engraving (Bonus: Not Printing) Best for: Metal dials/plaques with ultra-sharp, permanent markings.Pros Extremely durable, precise; can be color-filled after engraving.Cons Not for photographic art; mainly line art, numerals, or scales.Pro tips Pair a brushed aluminum dial with laser-engraved indices for a minimalist luxury look. Quick Selection Matrix Scenario / Goal Best Methods Notes Bold, high-contrast retail dial (ABS/PS) Screen Printing Pantone spot colors; durable; cost-effective mid–high runs Short run, photo/gradient artwork UV Flatbed CMYK+White; textures/varnish; validate adhesion Very large volume, photo detail (paper insert) Offset Litho Laminate + anti-glare; strong QC on color Metallic numerals / premium accents Hot Foil (+ Screen) Requires die; stunning brand impact Patterned look (wood/marble) on case/dial Hydrographics Add protective clearcoat Boutique logos on glass/metal, low MOQ Decal Transfer Clearcoat for longevity Industrial, permanent marks on metal Laser Engraving Can color-fill; ultra-durable File Prep & Color Management (Save headaches later) Vectors first: Supply AI/SVG/PDF with text outlined; raster elements ≥ 300–400 dpi at 100% scale. Pantone callouts: Provide PMS refs for brand colors; specify coated/uncoated. Safe zones: Keep numerals/markers inside the dial’s safe area; add 1–2 mm bleed where needed. Minimums: Hairline ≥ 0.3–0.4 mm; negative text ≥ 0.5 mm stroke. Proofing: Approve 1:1 paper mockup on the wall for legibility, then a pre-production sample on the real substrate under retail lighting. Durability & QC Checklist Adhesion: Cross-hatch/tape test on actual substrate. Abrasion: Finger-rub/scratch test; lens contact points. Lightfastness: UV exposure check to guard against fading. Cleaning resistance: Test with common cleaners/microfiber. Color delta: Measure ΔE vs. brand targets where applicable. Assembly fit: Verify hand clearance and no ink ridges causing interference. Lead Time & Cost Drivers Setup/tooling: Screens, foiling dies, jigs. Color count & special inks: Metallics, fluorescents, white, spot varnish. Substrate: Glass and metal need pretreatments/primers. Run size: UV/digital suits small runs; screen/litho are efficient at scale. Finishing: Clearcoats, anti-glare films, emboss/foil combos. What We Recommend (by use case) Mass retail, everyday brand clock: Screen print on ABS/PS with anti-UV inks + matte lens. Boutique/premium: Back-printed glass via UV (with white + protective clear) or aluminum with laser + fill; add hot foil on indices. Campaign/seasonal art: UV flatbed for fast turns and variable graphics; or offset for very high volumes. Patterned décor lines: Hydrographics on bezel + simple high-contrast dial print.
