The most traditional framing method is matting a print. Beneficial and simple, the mat is a thicker piece of cut board which is placed over the print to create a 'white space' between the print and the frame.
The mat gives a print space away from the glass which protects the paper from mould and keeps it flat. As well as archival benefits, matting your art increases the overall size and enhances the presence of a piece on the wall. Almost any frame can be used with a mat making it a versatile option.
