Encapsulated PostScript File (.epsf)
An EPSF, or Encapsulated PostScript File, is a graphics file format used primarily in the publishing and printing industries for embedding high-resolution images within other PostScript documents. Introduced by Adobe Systems in the late 1980s, EPSF files enable seamless integration of complex visual elements, maintaining quality and device independence. They encapsulate both vector and raster graphics, allowing detailed illustrations and photographs to be embedded without loss of resolution, facilitating professional-quality output across various platforms and devices.
