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.

Encapsulated PostScript Interchange with TIFF Preview (.ept)

The EPT file extension stands for Encapsulated PostScript Interchange with TIFF Preview. It is primarily used in professional graphic design and desktop publishing, particularly with Adobe software. EPT files combine PostScript data for high-quality printing with a TIFF preview for on-screen viewing. This format emerged to facilitate the exchange of complex graphic files between different systems and applications, ensuring both print accuracy and visual consistency. Its adoption has been crucial in workflows requiring precise color management and detailed image rendering.
