flatten layers

To bring all levels of a multi-layered image down to one plane. High-end graphics programs provide a multi-layer file format, such as the Photoshop Document (PSD), which enables elements in each layer to be manipulated independently. In order to save the layered image in a single-layer graphics format such as TIFF or JPEG, the image is said to be "flattened."

An Adobe PDF file is also flattened to remove a transparency layer when the document is rendered in a printer or in an application that does not support the additional layer. See layers and PSD.
