Sample Lab Day service gets your crew up to speed on UV bottle decoration, either on your site or at our Germiston bench, depending on the job. We walk you through set-up, first test prints, and how to check for the usual problems, flaking, smudges, and handling marks, before your main stock arrives. This is not a classroom or a sales talk. We work alongside your operators on your bottles, using your real constraints. The goal is that you, not a visiting specialist, can run with confidence when Monday’s order lands.
This service works best for craft beverage makers, skincare labs, and promo lines with in-house or near-site print rooms who need a repeatable, durable result. If you outsource all your packing or hand off to a contract filler, it may not fit your workflow. You need at least one team member who will work hands-on for the day.
Sample Lab Day is made for teams who handle their own bottle customisation, whether you are in a Highveld industrial park or a back room in Durban. It suits operators who can set aside a morning, make a few changes with supervision, and want to avoid late-stage flops when the bigger batch comes through. If you have a crew used to load-shedding, variable humidity or running on three-phase, you are in the right place.
For businesses who just need a finished sample and never touch machinery, or who require full-service contract packing, our other sample programmes or referral to a trade finisher are better bets. We are not right for sites where no technical operator is available, or where management wants a single-pack demo for internal sign-off only.
We start by checking your bottles, glass, aluminium, PET, whatever you run, and your incoming artwork (even if it’s a late-night WhatsApp snap). We match the right fixture, ink, and print pass to your site’s quirks. If you are in Paarl, that might mean a different ink for the afternoon temperature jump, or in Gqeberha, a tweak for coastal humidity.
Your operators get hands-on with setup and the first print, guided through checks for poor adhesion or hazing under shelf light. If a revised drawing lands at midnight, we ask you to send it before we crate the gear, not while we are already on the road. A single day on site usually gives you a clear record of what worked, where it hiccupped, and what to repeat for production.
A Gauteng craft gin team booked a Sample Lab Day after their first print batch rubbed off in transit to retail. Their operator worked alongside our team at their Sunnyrock floor. Using the actual gin bottles and label material, we ran test prints, tried three ink/fixture combos, and checked adhesion after a simulated crate drop. The fix in this case was a changed fixture to lock the tapered neck, a slower print pass, and a change in ink cure time. By the end of the day, the operator could repeat the process solo. A one-page note summarised the tweaks for future runs.
This pattern repeats in Cape Town, Polokwane, Bloemfontein, or wherever bottles and handling differ. The main win is a process that can survive both municipal paperwork delays and rougher transport handling than the brochure ever admits.
If you are ready to plan a Sample Lab Day, these steps make everything run faster. We do not need six PDFs. The checklist below is enough for the first round. Email everything through our contact form and let us know your city and preferred window.
If you have Sample Lab Day specifications or a fixture list, link those or attach them. We also recommend giving Sample Lab Day a read for the overall approach.
The most expensive mistakes start when the constraint, finish, fixture, or ink, is not written down before you brief us. Teams who skip this step often pay for a rush fee or need a second visit to redo faulty stock. Last-minute artwork revisions are another culprit. Always send the latest file before we ship any kit, or you risk lining up the wrong fixtures.
If you are between two hardware options, pick the line your crew can support without a call to the factory or a WhatsApp to the night operator. The proven choice usually outlasts a flashier but fiddlier setup. We record any job’s misses in a short note so your next batch avoids the same trip-up.
