Encapsulated PostScript Interchange (.epsi)

EPSI, standing for Encapsulated PostScript Interchange, is a file extension used primarily in the printing and graphic design industries. It stores PostScript data along with a low-resolution preview in bitmap format, facilitating the visualization of graphic content in layout applications without needing to interpret the complex PostScript code. Introduced in the 1980s by Adobe Systems, EPSI files serve as a bridge between different software applications, ensuring consistent and high-quality output in various publishing workflows. Their efficiency and adaptability have made them a standard for exchange of graphic data in professional environments.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
