Printing Color Internet-based Cad System

Printing CAD/CAM system can change traditional printing-design patterns and technics, realize Computer Aided Design and Computer Aided Make for textile, further, can reach the automation procedure, with the help of advanced computer technique , automation technique and mechatronics technique .With the development of textile and computer technology as well as the use of internet, higher requirements for printing CAD have been put forward. This paper mainly introduces a new kind of CAD system based on internet ,which utilizes computer graphics, digital image processing ,color model of computer, internet programming technique , remote database management and so on . according to the requirement of practical printing color-matching techniques, this paper provides a new arithmetic of color-making for printing pattern. Using the pattern recognition and knowledge of cjay modeling ,The remote design and management of printing scheme have been realized by apply CAD system to the internet through internet connection and programming as well as the image compression technique. This system apply C/S structure-client server(*) in charge of the pattern design and the scene modeling ,and transmit the result to the serve; the server will be responsible for the authentication of the visit requirement from the client server, besides, as a part between the client server and the background Oracle database, it provides the interface for client server to visit and manage the background database. Moreover, the server provides the communication of the character and picture between two client servers. From this way, a printing color-matching CAD system based on internet, server as the core, can be formed.
