Abstract
A laminate for making signs, the laminate comprising a readily-abraded layer and an abrasion-resistant layer. A method of making signs is also disclosed. The method includes providing a laminate comprising a first layer that is readily etched by abrasives and a second layer disposed beneath the first layer and substantially resistant to abrasive etching. A mask is applied to the top of the laminate; and abrasives are used to selectively remove a portion of the first layer, so as to form a relief image with a controlled and uniform relief depth.
