Term of the Week: Cap layer

The Term of the Week is a weekly feature where A&E turns to industry experts to define common tools, processes, language, etc. used in the awards, engraving, and personalization industry, including terminology within the business realm. Contact A&E's digital content editor, Julia Schroeder, if you're interested in contributing and for an opportunity to be featured in our daily eNewsletter. 

Engravable sheet materials consist of two, or sometimes three, layers. The top layer of the sheet is referred to as the “cap.” This is the layer a laser or rotary engraver will remove to reveal the bottom layer, or “core.” The cap layer is typically thinner than the core, which allows the laser or rotary machine to create fine details when engraving. The cap layer color usually contrasts the core layer color to provide easier readability and visibility.
