A brilliant Custom Jigsaw Puzzle lives or dies at the artwork file stage. We see beautifully-conceived puzzle briefs arrive at our Singapore press every week with files that quietly guarantee a mediocre result — wrong colour space, missing bleed, over-compressed JPEG, logo sitting right on a die-cut edge. None of this is catchable after plates are made. This guide documents the exact artwork prep we need from your side so your puzzle prints at the quality the brief deserves, and covers the photo-to-puzzle workflow we run for personal and family commissions.
Quick read: Send CMYK artwork at 300 dpi at final assembled size, with 3 mm bleed, flattened PDF or TIFF, and keep logos and headline text inside the middle 70% of the image. Photos should be native at least 3,000 px on the long edge. If you follow these four rules the plate is 90% of the way to a clean print.
How we actually print customised jigsaw puzzles
Cardboard puzzle printing in Singapore is an offset or digital print job applied to a laminated paper sheet, which is then glued onto 2 mm blue-board and die-cut through a steel rule tool. We use digital printing for runs of 300–500 units and offset for 1,000+ because offset unit cost drops sharply at scale while digital is flat. From an artwork point of view the two processes accept the same file, but offset rewards careful colour management more than digital does. Every format we describe below is available in the live Custom Jigsaw Puzzles in tube packaging catalogue.
Wooden puzzles are a different workflow — artwork is UV-printed directly onto birch plywood, then CNC or laser-cut. The file requirements are similar to cardboard but CMYK behaviour on wood is different because the wood grain contributes to the final colour. We always proof wooden artwork before committing to a full run.
Acrylic puzzles are UV-printed onto cast acrylic sheet and laser-cut. The artwork file needs a white-ink underlayer spec if the design uses solid colour over a clear substrate. Our design team adds the white layer on our side as long as your file is supplied in the correct layered format, which we cover below.
Colour space: CMYK is not optional
The single most common artwork mistake we receive is RGB files — typically exports from Canva, Figma, Keynote, or PowerPoint. RGB is a screen colour space. Print is CMYK. When we convert an RGB file to CMYK at our end, bright blues shift to muted blues, fluorescent greens go dull, and strong reds dim by roughly 15%. The final puzzle looks flat next to what the client saw on their monitor.
Convert to CMYK on your side using Adobe Photoshop, Illustrator, or InDesign, against a standard coated print profile such as FOGRA39 or GRACoL 2013. If you do not have Adobe, export the file as high-quality PDF with colour profile embedded and we will colour-match at our proofing stage — but this adds a round-trip and slows the job by one to two days.
Brand-colour check: if your brand guidelines specify a Pantone value (e.g. Pantone 485 C), include it in your brief. We can spot-match Pantones at offset volumes above 1,000 units. Below that, we hit a CMYK approximation — usually within 3 Delta-E of the Pantone, which is imperceptible to most viewers but worth flagging if brand-colour accuracy is critical.
Resolution, size and bleed
Artwork resolution is measured at final assembled puzzle size, not at piece size or at some abstract “1080p” spec. Every custom jigsaw puzzle print needs:
300 dpi minimum — higher is fine, but anything below 300 visibly softens on the final print, particularly on 2 mm board which does not absorb detail as readily as glossy paper.
Final size plus 3 mm bleed — if the finished puzzle is 297 × 420 mm (A3), your file must be 303 × 426 mm. The die-cut slightly overshoots the print edge and 3 mm of bleed covers any variance.
Keep critical content inside a 5 mm safe zone from each edge — logos, headlines, faces, anything you would hate to see clipped.
The resolution rule surprises clients most often. A 252-piece A3 puzzle and a 1,000-piece A3 puzzle need the same 300 dpi file because piece count does not change the print — it only changes the cut. Doubling piece count does not require a higher-resolution image. Our piece counts, materials and finishes buyer’s guide covers the full size-versus-piece-count decision in detail.
File formats we accept (and which we prefer)
| Format | Good for | Notes |
|---|---|---|
| PDF (print-ready, X/1a) | Everything. Our preferred format. | Must be flattened, CMYK, embedded fonts. |
| TIFF (uncompressed) | Photographic artwork. | LZW compression is fine. No JPEG compression inside TIFF. |
| AI or EPS | Vector logos, type-heavy designs. | Outline all fonts before sending. |
| PSD (layered) | Mixed photo + vector designs we will adjust. | Only send if we need to edit layers. Otherwise flatten. |
| High-quality JPEG | Photos only, as a fallback. | Quality 10+ (0–12 scale). Never a screenshot JPEG. |
What we do not accept, or accept only with caveats: PNG (RGB and lossless but not CMYK), Canva exports (RGB by default), PowerPoint or Keynote (vector but not press-grade), and screenshot-grade JPEGs. If your only asset is one of these, send it to us early — we will either convert it or advise you to rebuild the file.
Photo-to-puzzle: the retouching workflow
Personal and family photo commissions — wedding couple shots, pet portraits, graduation photos, baby milestones — follow a different preparation path from corporate artwork because the source is usually a single phone photo. About half of the photo files we receive need a 15-minute enhancement pass before they are fit for a 300 dpi print at A3. Our process:
Step one — upscale. A 1,200 × 1,800 px phone photo at 300 dpi prints cleanly at around 10 × 15 cm. To get to A3 we use AI upscaling (Topaz Gigapixel or Adobe’s Super Resolution) to bring the file to roughly 4,000 pixels on the long edge before we begin colour work. Upscaled files are visibly sharper than native phone-res files blown up in Photoshop.
Step two — colour and contrast. Phone cameras lean heavily on computational contrast and white-balance that does not survive CMYK conversion. We apply a light curves adjustment, pull white balance slightly warmer, and lift midtone contrast by around 5–10 points. This is subtle but consistent — people look like they are indoors, not like they are behind a blue filter.
Step three — remove distracting background elements. A puzzle is unforgiving of background clutter because the assembler studies every inch of the image for ten minutes. We will ask permission before extending backgrounds or removing background strangers from group shots.
Step four — soft-proof. We export a CMYK PDF proof and send it back for approval before plates are made. On photo-to-puzzle commissions this proofing round is non-negotiable because it is the only chance to catch colour drift before committing to the print.
Logo placement and piece-edge traps
A die-cut puzzle has a fixed piece pattern per size and piece-count combination. We cannot shift the pattern per order at standard MOQ — that would require a custom die, which adds cost and lead time. That means logos positioned by the client without knowledge of the piece grid can end up split across awkward joins.
Two rules avoid this. First, position any headline text or logo inside the central third of the image wherever possible — the central pieces are generally larger, the joins are fewer in that zone, and any unavoidable split lands at a letter-safe location. Second, brief us at the file stage if any single element is non-negotiable (e.g. a sponsor logo that must read cleanly). We will check the element against the die pattern and, if needed, recommend a micro-shift of the artwork of 2–5 mm to land the element entirely within a single piece or two adjacent pieces.
Printing decoration methods by material
Cardboard — offset and digital
Standard four-colour-process CMYK on laminated paper. Digital suits runs of 300–500 units; offset is unit-cost efficient from 1,000+. Both produce indistinguishable results at final finished quality — our clients rarely can tell which press a puzzle came off. Screen-printed spot colour is available as an overlay for brand-critical Pantone matches but adds cost.
Wooden — UV direct print
UV-cured ink deposited directly onto the wood surface, then laser-cut. UV sits on top of the wood rather than absorbing in, so colour pop is strong but the surface is less durable against scratches than laminated cardboard. For premium wooden puzzles we recommend a matte lacquer top-coat.
Acrylic — UV with white underlayer
UV print onto clear cast acrylic, with a white ink underlayer to give opacity under solid colour. Spot gloss is effectively automatic because the substrate is reflective. Popular for typographic brand puzzles and product-launch activations.
Magnetic — laminated print, magnetic backing
Standard cardboard front with magnetic sheet lamination backing. Print quality is identical to cardboard. The magnetic surface is less forgiving of heavy assembly — pieces can shift mid-solve if the surface is off-horizontal — so we recommend magnetic only for promotional leave-behinds, not as an activity format.
Proofing: what to expect and what to check
We send two proof rounds on every custom puzzle job:
Digital soft-proof (PDF), typically within one working day of artwork receipt. You check artwork alignment, crop, safe-zone content, colour accuracy (as best as a monitor allows), and spelling.
Hard proof (optional, charged) — a one-off printed sample on the actual board stock with the actual lamination. Only necessary for Pantone-critical brand work, very large orders, or when the artwork is being approved by a client stakeholder who has not seen the design yet. Adds 3–5 working days to the timeline.
Once proofs are signed off, the job goes to plate and no further changes can be made. For volume pricing and the full lead-time breakdown by puzzle format, see the wholesale lead times and volume pricing guide, which also maps how many working days to build in for each proofing stage.
Design tips that make puzzles actually solvable
Printing correctness is half the battle. The other half is whether the recipient assembles the puzzle or gives up. A well-printed puzzle that cannot be solved is still a failed gift.
Break up solid colour. Sky, ocean, brand background — any large uniform region is a nightmare to solve. Add subtle texture, a slow gradient, or embedded micro-detail within the region to give assemblers something to work against.
Vary contrast and focal points. A well-designed puzzle has two or three anchor regions the solver can build out from. Evenly-distributed detail is actually harder than a few clear focal points.
Respect the edge. Border pieces are the first ones assembled. A strong, readable edge region gives solvers early wins and keeps them engaged.
Use brand copy sparingly. A puzzle covered in small brand tagline text feels like a company newsletter. A single well-placed headline or brand lockup reads much better than a wall of copy. This is especially important for puzzles intended as branded puzzles for corporate D&D nights and event prizes, where recipients study the artwork while photographing it for social media.
Frequently Asked Questions
What resolution do you need for a custom jigsaw puzzle print?
300 dpi at the final assembled puzzle size, plus 3 mm bleed on all sides. Lower resolution softens noticeably on 2 mm board, particularly on photographic artwork.
Can I send artwork in RGB?
You can, but we will convert to CMYK on our side and colour will shift — typically bright blues, fluorescent greens, and saturated reds dim by around 15%. Brief CMYK where possible for true brand-colour reproduction.
What is the best file format for a custom jigsaw puzzle?
A flattened print-ready PDF (X/1a), CMYK, with embedded fonts and 3 mm bleed. TIFF is equally good for photographic artwork. We accept high-quality JPEG as a fallback for photos.
Can I make a photo-to-puzzle from my phone picture?
Yes. We run AI upscaling and colour correction on phone photos before print. Aim to send the highest-resolution original you have — ideally the unedited, uncompressed version straight from the gallery.
Will my logo be split across puzzle pieces?
Possibly, if placed at the artwork edge. We recommend keeping logos and headline text in the central third of the image. Brief us if any element is non-negotiable — we can shift the artwork a few millimetres to avoid it landing on a join.
How many proofing rounds do I get?
One digital soft-proof PDF is included. A physical hard proof is optional for Pantone-critical jobs and adds 3–5 working days and a proofing fee.
