Colour Trial Support

What colour trial support covers

Our colour trial support is aimed at shops that need a practical check before production starts. We help you compare output on typical materials such as PVC, vinyl, rigid board, coated paper, polypropylene sheets and other common sign and packaging surfaces. The goal is to confirm how the ink lays down, how it cures, and whether the finish is close to the target you want.

Because UV-curable ink can behave differently from one printer and substrate to the next, we look at more than colour alone. We also consider dot gain, gloss level, surface feel, adhesion and drying behaviour under the actual curing conditions you use. That is especially useful in Cape Town, Johannesburg, Durban, Pretoria and Gqeberha where humidity, heat and dust can shift results from one day to the next.

• Density and colour check on your chosen substrate
• Adhesion check after curing and cooling
• Gloss, matt and image clarity comparison
• Basic guidance on pass count, ink load and curing balance

How the trial process works

We keep the process straightforward so your team can get useful feedback without losing production time. If you send us the substrate details, printer type, print mode and the outcome you are aiming for, we can advise on the most practical trial route. Where needed, we assist with sample pack prep and colour trial support through our Epping, Cape Town base.

A typical process starts with a short compatibility check. We then help you define the target look, such as stronger solids, smoother skin tones, cleaner line work or better white coverage. After that, you run a test on the printer or we guide you through a remote check if the job is being set up elsewhere. Once the trial print is cured, we review the result and advise on next steps. There is a missing step on many jobs, and it is usually not the ink itself, it is the curing balance.

• Step 1: Confirm printer model, substrate and job size
• Step 2: Choose the trial setup and sample method
• Step 3: Print and cure a test sheet or test panel
• Step 4: Review finish, adhesion and colour appearance
• Step 5: Adjust settings and repeat if needed

What we check during a trial

Colour trial support is not just about whether a print looks good under office light. We check how the cured ink performs once the sample is handled, stacked or fitted. On UV systems, a print can look acceptable straight off the bed but still show weak adhesion, brittle curing or a slight tint shift after a short time. Our trial process is meant to catch that early.

We also look at printer compatibility in a practical way. Some flatbed and roll-to-roll machines handle certain ink limits, drop sizes and curing settings better than others. If the job uses a high-build white, a gloss finish or a fine detail image, the trial helps confirm whether the current setup can support it or if a settings change is needed.

• Adhesion after curing and cooling
• Colour density and shade matching
• Line sharpness and fine detail hold
• Surface finish under normal viewing conditions
• Handling behaviour on flatbed and roll-fed output

Turnaround and practical lead times

Turnaround depends on the substrate details, the sample format and the print conditions you want checked. For straightforward trials, support can start once that information is in hand. If you need courier stock support to Cape Town, Johannesburg, Durban, Pretoria, Gqeberha, Bellville or Paarl, we plan the timing around collection and the production queue.

Where a customer needs repeat order management, we keep note of the trial outcome so the same material can be matched again later. That matters for repeat signage, packaging runs and shop-fit work where the colour needs to stay consistent across more than one production batch. If the first sample is not right, we usually recommend a second pass rather than pushing a full run too early.

For urgent jobs, it helps to book the trial before the main materials arrive. That gives us enough time to prepare the advice, check the curing guidance and reduce the risk of wasted substrate.

Pricing approach for trial work

Our pricing approach is based on the type of support required, the number of samples, the level of technical input and whether courier delivery is needed. A simple colour check on a single substrate is priced differently from a full trial that includes compatibility checks, curing guidance and operator training. We quote according to the work involved, not on guesswork.

For many customers, the trial cost is less than the cost of reprinting a batch that missed the mark. That is the point of the service. We are careful not to over-spec the process, and we only recommend the steps that are needed for your job. If you need a sample pack prepared or remote tech help during setup, we can include that in the scope.

• Single substrate colour check
• Multi-sample comparison for different finishes
• On-site or remote support for setup issues
• Courier handling for sample movement and stock support

Care, maintenance and safe handling between trials

Good trial results also depend on how the printer and inks are handled between runs. UV-curable inks should be stored and used according to the safety data sheet, and operators should wear gloves when handling uncured ink, sample sheets or cleaned parts. Keep the work area free of dust, and remember that coastal humidity in places like Gqeberha and Durban can influence adhesion and curing more than people expect.

A small change in temperature, head health or lamp output can alter the final look more than the operator thinks.

• Use the safety data sheet for storage and handling
• Wear gloves when touching uncured ink or test prints
• Keep curing units and printer paths clean
