Overprinting - What is overprinting?
Definition of OVERPRINTING:
In printing, the term overprinting refers to the application of an additional layer of print (or a coating) over the top of an existing layer of print (or coating) that has already been applied to a substrate. This method of printing is used in a number of different ways. It can refer to the printing of additional information or designs onto a pre-printed medium such as labels or packaging; for example, "Best Before" and "Use By Dates" can be added to product packaging during the packing stage (rather than during the manufacturing of the packaging itself). It is also the term used to refer to the process of customising envelopes (for example, by adding a company logo or slogan after the envelopes have already been assembled), to the process of layering colours (usually the four process colours) to create a particular colour that is a combination of two or more process colours, and to the process used to create "rich black" (a combination of the CMY colours are printed first before a layer of black (also known as Key) is added over the top to create a very deep black).Go Back to Glossary
