Finish
LED UV CMYK puts full-colour images and branding on glass or PET bottles using factory-tough UV-cured ink. Used by labs, bottlers and promo lines needing visual punch that survives handling.

LED UV CMYK is a direct-to-bottle print finish designed for detailed, process-colour graphics on both glass and PET. Using Swiss-precise machines, we cure full-colour (CMYK) images onto bottles instantly with LED UV light. This produces print that can handle Highveld dust, coastal humidity and warehouse shifts without smudging or fading. It is a fit for short and medium runs in the craft beverage, personal care and promotions market. We log cure times and LED lamp output for every run to keep details repeatable and support shelf-life claims.
LED UV CMYK works well for anyone who needs eye-catching, photo-quality decoration that will last through packing and shelf handling. Most craft breweries, boutique skincare brands and promo lines can rely on it for colour logos, gradients, and complex label art. It suits runs where the design changes often or the artwork includes full-colour gradients, small text or digital textures.
It is not ideal for jobs needing metallic foils, textured inks, or flock. It also does not fully replace shrink sleeves for 360-degree wraparounds. If your brand mostly uses spot colours or metallic details, see Finishes for other options, including metallic accent and matte panel.
Our systems use LED UV lamps set for local power conditions (230 V or three-phase), with ink matched for South African storage and shipping. Operators set bottles into jigs, align the artwork in our workstation and run a sample pass. Each bottle is cured in-line under LED UV to lock in the CMYK layer. The print dries instantly, so bottles can move directly to packing lines or closure fitting.
We log every run by artwork, date, ink batch and cure output. This keeps things simple for repeat orders or if you need to prove print methods to a brand manager or buyer. Gauteng and coastal clients report consistent results, even through winter chill or summer build-up. Our site in Germiston is open to trade visits if you want to see process work on the floor.
A Gauteng-based kombucha brand switched to LED UV CMYK for seasonal batches. Their summer artwork was full-photo, with crisp gradients and a QR code pointing to a campaign page. We matched their PET bottle sample, ran a logged test pass, then queued a short run for two urban markets. Bottles left the floor with ink cured, ready for carton and shelf. The owner confirmed the decoration stayed intact through packing at the warehouse in Kempton Park, on to retailers in Rosebank and Pretoria.
For metallic look finishes or caps matched to artwork, combine LED UV CMYK with metallic accent or closure match set to achieve a complete branded effect.
Getting the best result from LED UV CMYK depends on a few details up front. Before you send us a message through our contact form, please gather the information below. It helps us check compatibility, plan your sample pass and avoid pitfalls like registration shifts or unexpected surface reactions.
Refer to our catalogue for bottle types or see opaque white underbase if your artwork needs to sit on dark glass. You'll save time and avoid back-and-forth if you cover these points at the start.
Some pitfalls can slow down your run or affect print durability. We see issues when artwork sits too close to panel edges, or where glass has subtle tapering and faint seams. Not all PET is equal: some grades need a clear PET primer to prevent cracking and ink lift during capping or transit. Cheap imported bottles sometimes give inconsistent grip. Plan for a logged test pass if this is your first run on a bottle type.
If your site faces irregular load-shedding, let us know in your email. We can plan test prints and handover to suit typical blackout slots, especially for clients in Durban or Gqeberha. For longest shelf life and colour hold, avoid stacking fresh bottles under high humidity while the ink fully sets.
