Generally the term “embossing” refers to any technique that create a raised pattern on a surface of materials such as paper, leather, or metal.You can achieve the result in various way including using embossing folders, letterpress, or heat embossing with embossing powders.
Embossing Folders are translucent plastic folders that have a raised design impression on side side and has an indented impression on the other. The design can transferred into the paper by simply inserting a piece of cardstock inside the folder then roll the folder through the die cutting & embossing machine. This creates a raised image on your paper or cardstock. This method is also known as dry embossing.
With heat embossing, a design (or texture) are added to the materials through stamping or writing with embossing ink and sprinkling with embossing powders and using heat to create the raised effect.
