Promotional shot glass printing is six different techniques in a trench coat. Most procurement buyers only ever see the final quote — not the reason silkscreen costs a third of UV print but only supports spot colour, or why laser engraving is permanent but kills the brand palette. This guide walks through every decoration method we run in-house at Aquaholic for Promotional Shot Glass Printing — with real durability numbers, artwork specs, MOQ notes and the event types each method actually suits. Read this before you brief, not after.
Six in-house decoration methods · MOQ 300 pcs · Lead time 30 working days onwards
The four axes of a print-method decision
Every shot-glass decoration decision resolves to a point on four axes. Get the axes right and the method picks itself.
1. Colour count
1 spot colour → silkscreen or pad. 2–4 spot colours → silkscreen. Full CMYK / photographic → UV digital. Frosted mono → laser or sandblast.
2. Service durability
~200 washes → pad. ~300 → UV. ~500 → silkscreen. ~1,500 → colour-fill engraving. Permanent → laser or sandblast.
3. Volume and MOQ
Silkscreen and pad hit unit-cost sweet spot at 500+ pcs. UV and laser hold flat unit cost at 300 to 5,000+.
4. Perceived-value signal
Mass giveaway → UV / silkscreen. Executive keepsake → laser + colour fill. Luxury understated → sandblast frosting.
Method 1 — UV digital print
What it is. A flatbed UV printer deposits droplets of CMYK (plus white) ink onto the glass and cures them instantly with UV light. The result is a thin, bright, full-colour image bonded to the surface.
Best for. Photographic artwork, gradients, full-colour brand lockups, launch hero imagery. Also the only viable method when the logo crosses multiple Pantones and you need a consistent look across a D&D favour, a trade-show booth shot and a wedding coupe.
Durability. Approx. 300 commercial dishwasher cycles with a primer pass. Essentially unlimited for handwash keepsake gifting.
Artwork. Vector preferred (AI/EPS/PDF, fonts outlined). Raster at 300 dpi at final size. CMYK workflow — supply CMYK or Pantone+CMYK conversion where brand tolerances allow.
Pairs best with. Heavy-base, cordial and V-shape bodies — the larger decoration area plays to UV’s full-colour strengths. For body-fit guidance see our shot glass body styles and material options guide.
Method 2 — Silkscreen (screen) print
What it is. Ink is pushed through a mesh stencil — one screen per colour — directly onto the glass, then kiln-cured for adhesion. The oldest technique in glass decoration and still the most cost-efficient at volume.
Best for. Single- to four-colour brand lockups at high quantity. Bar-program in-house glassware. F&B service where durability matters but palette is fixed.
Durability. Approx. 500 commercial dishwasher cycles when kiln-cured. Holds well under daily bar service.
Artwork. Vector with each colour on a separate spot-colour layer. Pantone (PMS) references required for colour matching.
Pairs best with. Standard shooter, heavy-base, square-base bodies — the flat face matches the screen cleanly. Above 500 pcs, silkscreen typically undercuts every other method on unit cost.
Method 3 — Pad (tampo) print
What it is. A silicone pad picks ink off an etched plate and deposits it onto the glass. The pad conforms to curved or irregular surfaces that silkscreen can’t handle cleanly.
Best for. Small logos on curved bases, uneven surfaces (the bottom rim of heavy-base shots) and very high-volume single-colour runs where silkscreen setup isn’t justified.
Durability. Approx. 200 commercial dishwasher cycles. Solid for keepsake gifting, marginal for daily bar service.
Artwork. Vector, 1–2 spot colours, minimum 0.4 mm line weight.
Pairs best with. Metal shots (curved sides), the underside of heavy-base shots, eco-plastic bodies. Not our first pick for a main-face logo on a clear-glass shooter — silkscreen usually wins.
Method 4 — Laser engraving
What it is. A CO₂ or fibre laser ablates the glass surface at a pre-determined depth. The result is a permanent frosted impression of the logo in the glass itself — no ink, no film, no wash-off.
Best for. Premium keepsakes. Whisky-brand activations. Executive gift sets. Individual-name monograms. Anniversary, retirement and milestone-birthday gifts where the glass is the gift.
Durability. Permanent. The decoration IS the glass surface. We’ve tested engraved heavy-base shots through 5,000+ commercial dishwasher cycles with no change.
Artwork. Vector, single-colour (engraving is monochrome). Minimum 0.25 mm line weight. Fine serif fonts below 8pt may lose legibility — we flag this on proof.
Pairs best with. Heavy-base, crystal, tinted glass (for subtle frosted contrast), metal (with fibre laser). Every milestone gift we ship starts here.
Method 5 — Colour-fill engraving
What it is. Laser-engrave the logo, then hand-fill the engraved recess with coloured ink — gold, rose gold, silver, white, or a brand Pantone. The fill sits flush, protected by the engraving depth.
Best for. Premium gifts where the brand colour has to show. Luxury wedding favours (monogram + metallic fill). Corporate D&D head-table sets where engraving alone reads too subtle.
Durability. Approx. 1,500 commercial dishwasher cycles. When the fill eventually wears, the engraved logo beneath remains permanently — the gift doesn’t “break”.
Artwork. Vector, single fill colour. Minimum 0.35 mm line weight (the fill needs a wider channel to sit cleanly).
Pairs best with. Heavy-base and crystal bodies in clear, or tinted bodies where a gold fill reads beautifully against amber or cobalt.
Method 6 — Sandblast frosting
What it is. A high-pressure abrasive stream masked to the logo silhouette removes the polished surface of the glass, leaving a frosted matte impression. The oldest “premium” glass decoration and still the most understated.
Best for. Luxury brands. Crystal-heavy event programs. Funeral and memorial keepsakes. Heritage-brand activations where printed colour would read crass.
Durability. Permanent.
Artwork. Vector silhouette. No colour. Minimum 0.4 mm line weight — the abrasive pattern loses fine detail below this.
Pairs best with. Crystal shooter, heavy-base crystal, cordial crystal, tinted glass (frosted area picks up light differently against the tint).

Artwork specs that save a revision round
File format. Vector preferred — AI, EPS, PDF with live paths and all fonts outlined. Raster art accepted at 300 dpi at final decoration size for UV print only. JPGs off social media will come back pixelated — we’d rather redraw.
Colour system. Pantone (PMS) references for silkscreen, pad print and colour-fill. CMYK for UV. If your brand works in Pantone only, tell us — we’ll convert and flag any shifts bigger than Delta-E 5 before we print.
Minimum line weight. 0.25 mm for laser engraving. 0.3 mm for silkscreen. 0.35 mm for colour fill. 0.4 mm for pad print and sandblast. Anything thinner risks legibility at final production.
White ink under-base. Essential for UV print on tinted glass or metal. Without the flood, brand colours shift against the body. We add this automatically and show it in the proof.
Bleed & safe area. Wrap decoration with 1.5 mm safe area to the edge of the print zone. Full bleed is supported on UV where the decoration wraps partly around the body — we’ll mock the wrap on proof.
Which method for which event?
Quick routing for the event types we see most in Singapore:
- Corporate D&D table favour → colour-fill engraving on heavy-base; premium feel, year-stamp-able.
- Wedding door gift (300–800 pcs) → laser engraving of initials + date on tinted glass; timeless.
- Bar-program in-house glassware → silkscreen on standard shooter; cost-efficient at volume.
- Product launch with launch artwork → UV digital on cordial or V-shape; carries the hero image.
- Distillery tasting flight → sandblast frosting on crystal cordial; luxury-understated.
- Outdoor / rooftop activation → laser on stainless steel shot; unbreakable.
- Club / nightlife launch → UV white-ink on LED shot body; reads vividly under the glow.
- Mass roadshow giveaway (1,500+ pcs) → silkscreen on eco plastic; unit cost lands cleanly.
Every one of these runs on our standard Aquaholic timeline — 300-pc MOQ, 30 working days onwards from artwork approval. For full procurement detail (volume bands, deposit terms, delivery options) see the procurement guide — MOQ, pricing bands and lead times.

Five common printing mistakes we catch at proof stage
- Pad-printing a high-detail multi-colour logo. Pad print is a 1–2 spot-colour method. Complex logos need UV. We re-brief when we see this.
- UV printing on tinted glass without a white under-base. The brand teal shows as navy. We insert the white flood and show both versions on proof.
- Laser engraving text below 8pt serif. The strokes close up in the frosting and the line reads illegible. We switch to sans-serif or increase size.
- Silkscreen on curved lower bases. Screen needs a flat face. The lower curl of a heavy-base shot isn’t flat enough — we move to pad print there.
- Assuming all methods survive commercial bar wash. Only engraving and sandblast are truly permanent; the rest have finite cycles. If it’s a bar-program order, we state the wash-cycle expectation up front.
