No design on paper, or even a computer screen can adequately represent the beauty of a decorated metal surface. A sample is an absolute must.
In order to produce a custom sample, the manufacturer will require a sketch, drawing, camera ready art, or a computer file.

Custom samples usually take several weeks to produce. There generally is a cost associated with production of custom samples.
