Why the image behaves differently on aluminium
Dye sublimation on coated aluminium works best when the image is prepared for strong contrast, clean detail and controlled colour. The coating takes the ink into the surface, so sharp files usually print better than soft, underworked images, and small defects can show more than they would on paper.
For Randburg, Johannesburg and the rest of South Africa, this matters when prints are viewed in bright offices, coastal light in Durban, or gallery spaces with spot lighting. If the file is too small, the panel may still print, but fine detail can break up and faces or text can lose crispness.
- Send the highest quality file available, preferably the original export.
- Keep logos, borders and text inside safe margins.
- Check whether the image is meant for close viewing or for a larger wall display.
The finish changes the whole read of the piece
Finish choice affects glare, colour depth and where the panel works best. Gloss gives stronger punch and higher reflection. Matte softens the surface for rooms with direct light. White aluminium suits full-colour photographs and clean graphics. Brushed aluminium leaves a visible metallic grain that can work well for monochrome, industrial subjects or selective colour treatments.
In offices with overhead lighting, matte often reads more comfortably. In a home lounge or reception area, gloss can add richness if the wall does not catch too much glare. Brushed panels need careful image choice because pale areas may take on the metal texture, which is part of the look.
- Gloss for vivid colour and strong impact.
- Matte for less reflection and easier viewing.
- White for the broadest colour range.
- Brushed for a visible metal character.
How to judge whether your file is print-ready
Resolution review is not only about pixel count. It is also about crop shape, source quality and how much the image will be enlarged. A file that looks fine on a phone may be too small for a 900 mm panel, especially if the image has already been compressed or cropped several times.
Before a panel goes into production, check the image at final size. Watch for soft edges, heavy noise in dark areas and low-quality screenshots. If a file needs rescue work, colour preparation and crop planning can often improve the result, but there is a point where a new source file is the better call.
- Do not enlarge small images without checking the real print size first.
- Make sure any text is large enough to stay legible at viewing distance.
- Leave room for crop adjustments around the edges.
Mounting that suits the wall, not just the print
Hanging hardware should match the panel size, weight and the wall surface it will land on. Smaller pieces may use concealed mounts or a light hanging method, while larger panels often need a more secure system. For tiled walls, plasterboard or masonry, the fixing choice changes and so does the placement plan.
In Johannesburg offices and Pretoria reception areas, panels are often placed where people walk past them daily, so alignment matters. In humid coastal towns like Gqeberha and Durban, the mounting approach should also support long-term stability and clean wall contact. It is worth deciding early whether the work will hang singly or as a set.
- Confirm the wall type before choosing fixings.
- Match the hardware to the panel size and weight.
- Decide on single panels or multi panel layouts before production starts.
What to plan before a batch order
Businesses ordering several panels often need consistency across colour, size and finish. That is where test panels, reprint matching and finish selection help prevent surprises. If the project includes a lobby, meeting room and corridor, each space may call for a different surface even when the artwork stays the same.
Pack and delivery also need planning, especially for regional orders to Cape Town, Durban, Pretoria or Gqeberha. Panels should be packed to reduce surface scuffing and edge damage, and the delivery address must be ready for receiving. If a set will be installed in stages, label each panel clearly so the sequence stays intact.
- Decide whether all panels must match exactly or vary by room.
- Plan delivery dates around the installation schedule.
- Keep the file names and sizes organised for each artwork.
Rights, reprints and care after install
Customers must own the images they send, or have clear rights to use them. That applies to portraits, artwork, commercial imagery and any file supplied for a panel run. It is also worth checking whether a reprint may need to match an earlier job, because colour can shift slightly between different source files and different display conditions.
After installation, care is usually straightforward. A soft cloth and light cleaning is enough for most panels. Avoid harsh chemicals, abrasive pads and rough handling at the edges.
