Printed Acrylic Base for an Etihad Rail Model
The model makers building an Etihad Rail presentation model came to Sun Studio with its base: a large oval of acrylic carrying the whole route across the country.
It was printed direct onto acrylic (the sea, the desert, the mountains and the line itself), with the artwork built up so the terrain can be felt as well as seen.

The brief
A presentation model is looked at closely and from directly above, which is the hardest way to view a printed surface. Every seam, every registration error and every flat patch of colour is visible from a metre away.
The base also had to survive the rest of the build. A model base is worked on for weeks after the print is finished: components glued to it, parts positioned and repositioned, hands and sleeves across it constantly.
Our approach
The terrain was printed straight onto the acrylic rather than onto a sheet laminated to it. That keeps the image on the acrylic itself, with no laminated layer to lift at an edge while the model is being assembled.
Because each pass of UV ink cures instantly, further passes could be laid on top of the last. The coastline, the mountain ranges and the route were built up in relief, so the geography reads by touch as well as by eye. It is the same layering used for tactile signage, applied to a landscape.
The sea is the giveaway on a job like this. A large area of flat deep blue shows every banding artefact and every colour step, so it has to be printed evenly from edge to edge.
Production detail
Acrylic prints well once it is clean, and cleanliness is the whole job on a panel this size: a single fingerprint or a trace of static-held dust under the ink stays visible once it is printed over. The panel was degreased immediately before it went on the bed.
UV ink is cured by light rather than dried with heat, which matters on acrylic: a large sheet that is heated unevenly can stress or distort, and a distorted model base is scrap.
The result
A model base that reads as landscape rather than as a printed sheet, with the route and the terrain standing up under the fingertips.
