This standard was first formulated.

GB/T 21185-2007/ISO/IEC 15775:1999 Information technology - Office equipment by analog test evaluation Color copying machine image printing method performance Production and Application

1 Scope

This standard applies to color copiers test version of the production and application. The standard image as a color copier prints Performance Test Standards Registration, in order to better identify the capabilities and limitations and compare between the copier.

When using this standard test copier, use at least 8 Beta 2 in the beta (a black and white and one color).

Copy product to do a visual inspection can also be compared with the test version, you can also copy these products objectively measured.

The standard 8 beta, including four halftone beta (1 photo, 3 offset printing), four continuous tone Beta (photography).

According to simulate all of the standard beta production, valid for three years.
