Based Printing And Dyeing Industry, The Digital Cad System

Printing and dyeing CAD system can change traditional patterns and technics , realize Computer Aided Design and Computer Aided Make and reach the automation procedure with the help of advanced computer technique , automation technique and mechatronics technique .First, the article mainly introduces the technics owned by advanced CAD system and illuminates primarily data management,graphic color-separation arithmetic and halftone's conception . The article illuminates mainly two segments color-separation model based on three dimensions , gives a model conception on a knowledge base of unification technology and analyse and design digital prepress system from the whole on the problem of systemic requirement analysis . Second , the article brings forward new data compress method based on memory stream and sets up new data structure to realize undo and redo methods based on analyzing all kinds of datas referred to on systemic based construction . Because printing and dyeing CAD system deals with many arithmetics on graphics ans image and production technics , the article illuminates vector conception , expatiates gray graphic vectorization and brings forward to graphic component's conception to enhangce the systemic stability and manipulating speed and improve graphic transmission . Third , the article uses for reference Adobe Photoshop's methods and authorizeds interrelated graphic arithmetics used in color-separation . The article not only gives a new clustering algorithm on color quantization , but also builds up new technics model based on mathematics modeling.With the development of CAD system and production technics , I brings forward to a series of graphic arithmetics and builds up many models on production technics . The printing and dyeing CAD system has excellent practicability , stability and application value .
