The printing method behind your cups is a decision that happens off-stage, but it shows up clearly on the finished product — in how fine the detail looks, how colours sit, and what the run costs. For custom paper cups there are two methods in play, offset and flexo, and they are matched to the cup you choose. Here is what actually changes between CMYK offset and flexo, so you can picture the result before you order.
The two methods in plain terms
Offset printing transfers the inked image from a plate onto a rubber blanket, and from the blanket onto the material. That extra step lets it lay down very fine, even detail, which is why offset excels at photographic images, smooth gradients and small text. At Nordicup, double-wall cups are printed by offset.
Flexo (flexography) uses a flexible relief plate that prints directly onto the surface — think of a very precise, high-speed stamp. It is efficient and superb at bold, solid colours and clean line work, which makes it a natural fit for logo-led and one- or two-colour designs. At Nordicup, single-wall cups are printed by flexo.
Detail and image quality
If your design leans on subtle gradients, a full-bleed photograph, or lots of small text, offset is the method that renders it most faithfully. The blanket step gives it an edge on fine tonal transitions and crisp type at small sizes. Flexo, in turn, is excellent where the design is built from strong, solid areas of colour and confident shapes — a bold wordmark, a two-colour pattern, a clean icon. Neither is “better” in the abstract; they are suited to different kinds of artwork. A photographic seasonal design and a punchy single-colour logo have different natural homes.
Colour: CMYK versus Pantone
Both methods work with the same two colour approaches. Full-colour CMYK builds every shade from four process inks and is the route for photographic and gradient-rich designs. Pantone spot colours mix a specific ink to a reference, giving the most consistent match for a brand-critical colour — and “one or two colours are often the most economical print.” Whichever you pick, printing uses water-based inks: no marks on wet hands and no odour. If exact brand colour matters more than photographic richness, a Pantone spot on a flexo single-wall can be both sharper and cheaper than trying to hit that colour in process CMYK.
Cost: what really drives it
Print method is only one input to price. The bigger drivers are usually the number of colours in your design and the cup construction itself. A simple one- or two-colour design on a flexo single-wall cup is the economical end of the range and scales well at volume. A detailed, full-colour design on an offset double-wall cup sits at the premium end, and you are paying for both the richer print and the more substantial cup. The clean way to think about it: pick the construction and design ambition first, and the sensible print method largely follows.
The print method is tied to the cup you choose
This is the point that saves the most confusion. You do not specify “offset” or “flexo” in isolation — you choose a cup, and the method comes with it:
- Single-wall → flexo. Light, classic, 4–16 oz, ideal for bold solid colours and economical one- to two-colour designs.
- Double-wall → offset. Firm and insulating, 8/12/16 oz, ideal for photographic and finely detailed full-colour artwork.
- Embossed “waffle” and cold-drink → advised per design, so ask your specialist which route best suits your artwork and volumes.
So a good early question is not “which printer?” but “what does my design need, and which cup carries it best?”
Which should you choose?
Start from the artwork. If it is a rich, photographic or gradient-heavy design and you want a premium cup in the hand, offset double-wall is the natural pairing. If it is a strong logo or a one- or two-colour identity and you want the best price at volume, flexo single-wall is hard to beat. If you are torn — say, a detailed design but a tight budget — that is exactly the trade-off a specialist can help you weigh, sometimes by simplifying the artwork to a spot-colour version that prints beautifully and costs less.

What stays the same either way
Whichever method prints your cups, the fundamentals are constant: water-based inks, a choice of CMYK or Pantone, artwork placed on a size-specific dieline, the same three-step proof (file check, digital proof, written approval), and production under ISO 9001 and ISO 22000. The method changes the character of the print; it does not change the care around it.
FAQ
Which method gives better photo quality on a cup?
Offset. Its plate-to-blanket process reproduces gradients, fine detail and small text more smoothly, which is why it is used for the double-wall cups suited to detailed, full-colour designs.
Can flexo print full colour?
Flexo can print in colour and is outstanding for bold, solid areas and one- to two-colour designs. For finely graded, photographic artwork, offset renders the subtle transitions more faithfully.
Do I choose the print method, or the cup?
You choose the cup and the method follows: single-wall is printed by flexo and double-wall by offset. Decide based on your design and the feel you want in the hand, and the print method is matched to it.
Will my exact Pantone brand colour be reproduced?
Specifying a Pantone spot colour gives the most consistent match to a brand-critical colour, often more precisely and economically than mixing it from process CMYK. Your specialist will confirm the best approach for your palette.
Does the print method change the price much?
Method matters, but the number of colours and the cup construction usually drive price more. A simple flexo single-wall run is economical at volume; a detailed offset double-wall run sits at the premium end.
