Debossing vs. Embossing
Embossing and debossing are two decoration methods I constantly hear misused. Prior (to what seems to be) popular belief they are two different effects!
Embossing refers to the creation of a raised impression under high pressure of a logo or lettering on materials such as paper, cloth, metal, or leather. Debossing refers to raising the material around the die impression. The most popular style of debossing and embossing in the promotional products industry is blind embossing which is embossing without using any ink.
The easiest way to remember the difference between embossing and debossing: embossing presses the logo into the material and debossing pushes the logo down into the material.
