Overview

Impression was the name of a series of desktop publishing applications for RISC OS produced by Computer Concepts. The first application was simply called Impression. A second release of this application introduced the Impression II product. Later applications used the Impression name, but were aimed at particular markets or types of user: Impression Junior, Impression Style, Impression Publisher.

Applications in the series shared a common file format, but there were some differences between different products in the series. Initially, documents were stored as a collection of files in a directory, but later versions could store documents in single files with a file type of bc5 (ImpDoc).
