Mixed Raster Content. This technology can be applied to PDF (PDF/A) files and represents a document as three different layers: the first one is a foreground plane with pictures, the second one is a mask plane with the text and its coloring, and the third one is a background plane with background pictures or textures. Each layer is compressed separately using the best type of compression for that data type. Learn more: PDF Conversion.
