Method for realizing multimedia printing system suitable for low-precision printing

Abstract

The invention relate to a method for realizing a multimedia printing system suitable for low-precision printing. The system consists of a multimedia printing plate making device, a multimedia printed matter and a multimedia broadcasting device, wherein, the multimedia printing plate making device consists of an output part, an editing part and an input part; the multimedia printed matter of multimedia broadcasting value information which is embedded for broadcasting a multimedia data is printed on the printing medium; and the multimedia broadcasting device broadcasts the multimedia data from the multimedia printed matter. The broadcasting value information is a possibly geometrically distributed or physically distributed net screen coding which is conversed into the pattern recognition of a printing net screen characteristic with at least one characteristic such as a gamma characteristic, a node characteristic, a node distant spacing characteristic, a node distributing characteristic and a node color characteristic. The invention has the following characteristics: the method uses minimal dot matrix digits to realize information recording and information embedding, has a little influence to a printing image and large recorded information capacity, and is not only fit for common printers but also fit for realizing multimedia printing on the printers.

Description

technical field

[0001] The invention belongs to a method for realizing multimedia printing suitable for low-precision printing in the field of information processing. Background technique

[0002] In recent years, publishing from paper media has rapidly evolved to electronic publishing. However, due to the intuitiveness, cheapness and convenience of paper media, although the number of paper media publications is decreasing, paper media publishing will not be eradicated, and paper media publishing will inevitably continue for a long time. The technology of combining paper media publishing with electronic publishing has attracted great attention. It can be concluded that the multimedia printing technology representing this trend will be the key technology for another revolution in the printing industry in the next century.

[0003] People have had various ideas about multimedia printing technology. As early as the 1990s, in Japan, someone proposed "reference sound output devi...
