Analysis of technical conditions of plate printer (I)

preface

this standard is a revision of technical conditions of plate printer compared with ZB j87 001-86

compared with ZB j87 001-86, the main technical contents of this standard are changed as follows:

-- the uniformity of illumination is increased from 85% to 86%

-- the repeated exposure time error is detected by two types of models:

a) the repeated exposure time error of the plate printer with the exposure time controlled by the timer is increased from ± 5% to ± 1%

b) exposure control the automatic compensation function of light quantity of the printing machine with automatic light quantity compensation system

this standard will replace ZB j870 from the date of implementation, and the cost will not appear too high 01-86

this standard is proposed and centralized by the National Printing Machinery Standardization Technical Committee

this standard was drafted by Jiangsu Taiyi group company and Qufu Normal University machinery factory

the main drafters of this standard: Chen Yulin, Gao Liping

this standard was first published on December 5th, 1986

technical conditions of plate printer

■ 1 scope
