Set up your Sunnyrock Sample Lab Day for success by preparing the essentials our team needs in advance. This checklist helps craft, promo, and skincare lines keep trial runs tight and productive.

A sample day at our Sunnyrock bench is how you test bottle decoration on real glass, aluminium, or plastic from your line. For South African bottlers, contract fillers, and studio teams, it’s the best way to see UV print results that match your handling, shelf conditions, and transit hazards. It suits any operator needing to check how artwork stands up before running a full batch. If your brand needs rushed launches, one-off event bottles, or multiple variants, a sample run is essential. For teams with fixed specs or global signoff processes, sample day may help but won’t replace full QA steps at destination.
Sample days suit hands-on Gauteng businesses, Cape Town and Durban craft beverage founders, and in-house print rooms needing straight answers on adhesion, curing, coverage, or bottle fixturing. If your range includes odd shapes or odd-lot sizes, we’ll spot trouble before it costs time on the line. Agencies and studios sending pre-launch work for promo or skincare also see real shelf survival here first, before artwork leaves the bay. Product owners needing full compliance for export or regulated markets will still need those steps downstream.
You brief our Sunnyrock floor with bottle samples, artwork, and decoration goals. Our team loads your bottles, tunes setups, and runs prints on your actual stock. We check each print for adhesion, coverage, and finish under conditions that match your warehouse or transit risks. Final prints often go back to you (or your boss) for handling, label fit, or packout checks. Where needed, we’ll mark up what changed, inks, jaws, or settings, for your next run. Feedback is honest and jargon-free.
For a smooth trial, tap into our fixture jaw guide or FAQ, UV bottles for common fit or inkflow questions. If your artwork runs full-wrap or has tight registration, check our sleeve registration notes to prevent last-minute snags.
A kombucha brand based in Germiston needed to test three bottle types, amber glass, clear PET, and a new short-neck shape for a limited run. They emailed us CADs, logo files, and five samples of each bottle, noting expected handling in their distributor’s warehouse (polycrates, open Highveld air, frequent load-shedding pauses). On sample day, our team tested jaw fit, ran adhesion trials on all shapes, and flagged slight ghosting on the clear bottles. We adjusted ink settings and re-ran. All samples were packed for their founders, who checked shrinkage and rub-off back at their floor. Feedback was used to tweak spec sheets before the first full order.
Get the full value from your sample day by sending the right kit and info up front. Double-check the list below before you email our team to book a slot.
Sample day drama usually starts with missing info or too few bottle samples. If your team forgets matching lids or leaves out artwork files, print fit and adhesion checks may stall. Bottles sourced from different suppliers can have tiny size or finish differences, a single test piece won’t show this, so always send extras. Underestimating how bottles will be handled (from packout in Polokwane to a store shelf in Durban) can mean the first full run fails when it counts. Always be clear if you need exact colour or finish match, as ambient light and ink batch may vary.
If you’re shipping in from outside Gauteng or using third-party couriers, allow for delays and check our shipping samples page for local advice. Keep your own notes during the trial and review our cure log template for record-keeping that helps next time. For stubborn jobs, ask us for the InkFlow viscosity card or GlassGuard care card so your team keeps results consistent.
