Computer plotting system and computer plotting method for making signssigns

Abstract

The invention discloses a computer plotting system and a computer plotting method for making signs. The computer plotting system comprises a working computer, a drawing file server, a database server and an imagesetter which are interconnected in the way of a local area network way. The computer plotting method for making the signs comprises the following steps: (1) judging if patterns similar to that of the signs which need to be plotted are searched or not; (2) if not, plotting the patterns of the signs according to needs; (3) judging if the patterns accord with requirements or not, if not, extracting parameters of the patterns; (4) after the patterns are modified, returning to a pattern plotting module to plot the patterns; (5) if a judging result of the step (3) is that the patterns accord with the requirements, transmitting a pattern file to a pattern information database for storage and also transmitting the pattern file to a color separation module to separate colors; (6) splicing a plurality of objects into a pattern integer; and (7) setting printing parameters of each item to generate a file in plt format for being distinguished by the imagesetter. The invention reduces the capacity of the pattern file from about 1G to dozens of k, thereby reducing the rigid disk resources occupying the computer.

Description

technical field [0001] The invention relates to a computer drawing system and a drawing method, in particular to a sign making computer drawing system and method, and belongs to the field of computer technology. Background technique [0002] With the popularity of computers in factories, more and more companies use CAD software for drawing. In the sign making process of sign factories, CAD drawing software is generally used to draw and save the sign graphics that need to be produced in the computer. Then convert the sign graphic file into a file format compatible with the laser imagesetter and output it to the imagesetter, and the imagesetter prints out the film for production. However, the existing signage graphic drawing system uses the PB file format to save the file, and then outputs it to the phototypesetter of Japan Screen Company. The computer hard disk resources are huge. This kind of signage graphics drawing system has huge computer hard disk resources occupied by ...

Problems solved by technology

However, the existing signage graphic drawing system uses the PB file format to save the file, and then outputs it to the phototypesetter of Japan Screen Company. The computer hard disk resources are huge. This kind of signage graphics drawing system has huge computer hard disk resources occupied by one file, which brings obstacles to the large-scale production and file management of the factory. Therefore, the existing signage graphics drawing system is improved to solve the problem. This question is necessary
