Galley, the process of stock is transferred to by printing machinery and ink special.Halftone, also known as " screen ", " screen ", " net
Line version ".The optical tooling of photomechanical production.Relief printing plate and the common halftone of lithographjic platemaking, are that to be carved with wide black and white with two pieces parallel
The optical glass of line, it is intersected with each other in 90 ° closely sealed, grid is formed, before being mounted in egative film during photograph, splits incident ray, due to spreading out
The effect of penetrating, makes to form site of different sizes on egative film, to show the deep or light level of picture.Mesh structure has criss-cross, circle
The forms such as shape, chain, common-use size for 20-80 lines/centimetre.The common halftone of gravure plate-making is made of glass or film, table
Face has white microgroove to intersect lines, forms grid, and during plate-making, the glued membrane at white line is not corroded because of light after-hardening, makees
For protect the space of a whole page support, common-use size for 60-100 lines/centimetre.Separately have a film screen of dizzy shape site, during use with sense
Mating plate and egative film contact printing, are called contact screen.
When being printed using halftone, the positioning accuracy of halftone directly influences the quality of printing, and existing halftone is determined
Position method is simple, and positioning accuracy is relatively low.In addition, when being printed to stock, due to the humiture of stock local environment
Condition changes, and stock itself influences the positioning accurate of halftone since different degrees of deformation will occur for the property of material
Degree.
