What colour proofing shows before we print
Colour proofing is the step that tells you how your artwork will behave on perforated one-way vision film before a full run goes to print. It is especially useful where the graphic must look sharp from the street while still allowing visibility from inside the shop or vehicle. On perforated media, small details can close up, dark tones can look heavier than expected and fine text can lose legibility if the artwork is not set up correctly.
We use proof samples to check the balance between ink coverage and open perforation area, then compare that result against your intended use. A proof helps you see whether a logo needs more contrast, whether a background should be lightened, or whether a message is too small to read from across the road. It also helps confirm the look on glass with natural light behind it, which is where many graphics are judged in practice.
- Check contrast on lighter and darker backgrounds
- Test image clarity on 70/30, 60/40 or other perforation ratios
- Review fine text, contact details and logos before production
- Confirm how the print reads from outside and from inside
How we prepare proof samples for perforated media
The process starts with your artwork file and a short check on size, viewing distance and where the film will be fitted. A shopfront in Bellville needs a different reading distance from a minibus window in Durban, and a proof should reflect that. We then prepare a test layout using the actual film type, print method and laminate that will be used on the final job.
Colour proofing can include a simple visual proof for layout and readability, or a more specific sample that checks tone shifts, colour density and opacity. For vehicle work, we also look at window curvature, door frames and any line breaks that may affect the final finish. If artwork needs changes, we adjust the file and proof again before the job is released to production. That saves time later and avoids reprinting panels that do not read well on the glass.
- Artwork file check and basic prepress review
- Proof layout against the actual perforation pattern
- Review of text size, colour balance and image detail
- Optional revisions before full print approval
Specs we check during proofing
Perforated window film is not a one-size-fits-all product. The open area, print density and laminate choice all affect the final result. For shopfronts, we usually aim for clean external graphics with enough interior visibility for staff to see out. For vehicles, the proof must also support legal driver visibility, so the artwork cannot block the view more than current road rules allow. The latest road traffic requirements should be checked before fitting any film to windows that affect the driver’s line of sight.
During proofing, we check the technical points that matter on site: glass finish, daylight conditions, edge clearance, handling marks and how the print will sit after installation. If the job is for a coastal area like Gqeberha or Durban, we also consider how humidity and sun exposure may affect the look over time. That matters when a client wants the same graphic across several branches or on a mixed vehicle fleet.
- Typical perforation ratios such as 70/30 and 60/40
- Print side orientation for inside or outside viewing
- Lamination choice for UV protection and scuff resistance
- Recommended text height for different viewing distances
Turnaround times and production flow
Proofing is usually the fastest way to reduce mistakes before a full production run. Simple colour checks can be turned around quickly, while artwork that needs multiple revisions or branch approvals will take longer. If the project involves a national rollout across Cape Town, Johannesburg, Pretoria, Durban and Gqeberha, we schedule the proof stage early so every site gets the same result. That is particularly useful for retailers with one campaign and several branches, or for fleet graphics that must match from one vehicle to the next.
Once a proof is approved, the project moves into wide format printing, lamination and then fitting or dispatch. If there is an old film to remove, we can include that in the planning so the surface is clean and ready. We keep the process practical: measure, proof, approve, print, install. No guesswork and no wasted material.
- Fast checks for small artwork changes
- Extra time allowed for multi-branch approvals
- Proof stage planned before print and install dates
- Can be combined with site measuring or vehicle templating
Pricing approach for colour proofing jobs
Pricing depends on the number of proof variations, the size of the artwork and whether the sample needs to be matched to a shopfront, a van side or a full set of vehicle windows. A single proof for a straightforward graphic is not the same as a campaign that needs several colour options and wording checks. We quote according to the actual work involved so you only pay for the proofing needed to make the job right.
For larger rollouts, proofing is often the most economical part of the project because it reduces avoidable reprints. It also gives clear sign-off for internal teams, landlords or municipal approvals where the glass area and visibility need careful handling. If the same artwork will be used again later, the approved proof becomes a useful reference for future refits and refresh work.
- Quoted by size, quantity and revision count
- Suitable for one-off jobs and repeat rollouts
- Helps reduce reprint costs on larger projects
- Reference sample can be kept for future refreshes
Care after approval and when to recheck
Once the film is printed and installed, colour proofing does not stop being useful. It gives you a reference point for routine cleaning and future maintenance. On shopfront glass, the surface should be cleaned with mild products and soft cloths so the print and laminate stay in good condition. On vehicles, washing should avoid strong solvents and rough scrubbing near edges or seals. That helps preserve clarity, especially where the film sits close to opening windows or curved glass.
After installation, it helps to inspect the film under natural light and again after the glass has settled into daily use. For shopfronts, offices or vehicle graphics, a sample proof can help you decide whether the tint, print or perforation should be changed before the next run. It is a small step that saves time and keeps the finished result close to the approved look.
- Clean with mild soap and soft cloths only
- Avoid scrapers, harsh solvents and pressure at the edges
- Recheck after installation and during regular maintenance cycles
- Useful for seasonal promotions and fleet refresh work
