Micrographics. Reader-printers for transparent microforms. Characteristics. | Status: Current

1 Scope This International Standard specifies the essential performance characteristics of reader-printers designed for viewing and making hard copies from microfilm with a maximum width of 35 mm, whether in microfilm strips or in roll form, in open reels, cartridges or cassettes, microfiche, jackets and image cards. It applies to reader-printers with a magnification less than or equal to 50:1. The requirements for the functions of readers, as specified in ISO 6198, are summarized in clause 4 for convenience of the users of this International Standard. This International Standard establishes minimum criteria for the hard copy prints produced by reader-printers based on the use of microtest charts ISO No. 1 and ISO No. 2 or from microforms with a specified minimum quality, either an original or a duplicate. This International Standard does not apply to special reader-printers that produce colour or other types of specialized microforms or prints. In addition, it does not necessarily apply to enlarger-printers.
