Debossed or Recessed Graphics on Aluminum Labels and Badges
Recessed graphics add visual appeal and depth to your nameplate. Recessed or debossed graphics are an alternative to raised or embossed graphics. The process used to create recessed graphics is an embossing process requiring tooling. Deboss refers to tooling which results in graphics that are recessed. Multiple levels of embossing and debossing are possible. Aluminum is most commonly used due to it's formability and flexibility in decorating. Stainless steel and brass are also options.
Attachment Options
Debossing graphics in metal results in a nameplate with raised graphics on the back surface. This requires careful consideration when determining the method of attachment to your product. Considerations when determining the attachment method for a nameplate with debossed graphics include:
Is the mating surface flat or contoured?
What is the mating surface made of?
Is the mating surface contoured to match the nameplate profile?
Will there be a formed edge on the nameplate?
How much bonding area is available on the nameplate?
Formed edges are popular, giving a badge depth and visual substance. Forming gives an illusion the nameplate is made from thick metal. The Frigidaire nameplate features a beveled edge and a formed edge or skirt. The Raynor nameplate has a slightly rolled edge and a shorter skirt. A solution for attaching nameplates with a formed edge is to assemble a foam adhesive to the back.
Embossing the entire background of a nameplate, leaving graphics at original height, results in debossed graphics. The JBL logo is manufactured this way and appears to be etched in metal. This type of emboss requires a thin edge around the part where the metal returns to original height. Consideration needs to be made for the amount of surface area available on the back side of the nameplate for attachment. Laminating adhesive after embossing generally increases the surface area available for attachment.
Applying adhesive after embossing maintains a crisper emboss. Costs are minimized when adhesive is laminated to strips or sheets of nameplates rather than assembled in the part. This maximizes the surface area for bonding and results in adhesive across the entire part. The Sunesta nameplate utilizes this process with a foam adhesive.
Heat activated adhesive is an option when the mating surface is contoured to match the profile of the nameplate. The adhesive is laminated to the nameplates in the sheet. The Whirlpool badge is applied to appliances using a heat activated adhesive.
The Beautiful plaque features debossed graphics and an overall low gloss transparent gold tint resulting in a subtle elegant look. This part is supplied without adhesive. Liquid adhesive is used for assembly to the Beautiful body lotion package. 
The Infinity label uses a multi-level emboss to create an attractive nameplate. Both the logo and graphics are debossed. A hot melt adhesive is used to assemble the nameplate to a molded backplate which includes attachment features.
