Summary of the invention
The objective of the invention is to the deficiency that exists at prior art, provide a kind of, the color of original copy is constituted be split as Huang, product, green grass or young crops, black four looks earlier, laminate with the forme of this four look again and print and the printing method of collotype of reduction original copy with the three primary colors principle.
For achieving the above object, the technical solution used in the present invention is: a kind of printing method of collotype, comprise Image Acquisition and convert color separation film, processes such as plate-making printing down and printing to, wherein Image Acquisition and the process that converts color separation film to be adopt transfer continuously electron colour scanner according to original image output Huang, product, green grass or young crops, deceive the continuous impregnation sheet of four looks; The process of described plate-making printing down is to use above-mentioned four coloring agent sheets to make four corresponding formes; The process of described printing is to use the printing ink of above-mentioned four formes and corresponding four looks to laminate printing.
Owing to adopted above technical scheme, the step that replaces the multiple special look of artificial division in the photo colour separation with electron colour scanner, no matter comprise all removable egative film that is divided into four looks of how many kinds of color in the original copy, the speed and the precision that have not only improved color separation make reduction more accurate, and significantly reduced the quantity of forme, cost is reduced.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
At first, briefly introduce the kind and the function of electron colour scanner.Electron colour scanner mainly is divided into site formula electron colour scanner and transfers electron colour scanner continuously, the former is widely used in the offset printing method, be used for original copy is scanned, output is corresponding to the various colour separation films of original copy, on film with the density of site to various color separations record in addition.The latter is at the continuous impregnation sheet of the various colour separation films that original copy scanned back output for no site, its key component comprises scan roller and light-sensitive roller, during use original copy is fixed on the scan roller, and film is installed on the light-sensitive roller, to be converted to analog electrical signal to the induction of various color separations through scanning process, be sent to the sensitization light source control end of light-sensitive roller, the strong and weak change records by the sensitization light source is on film.
For a long time, typography such as site forms such as offset printings obtains tremendous development, the method and apparatus of each link is perfect day by day, becomes the main flow of printing technology, and almost nobody adopts because shortage supporting technology and equipment are in printing industry to such an extent as to transfer electron colour scanner continuously.And transfer electron colour scanner in former using method, can only also limit its use to a certain extent continuously in the reflection mode to Manuscript scanner output and the identical colour separation film of original copy size.
The inventive method is introduced traditional collotype technology with modern technologies and equipment, proposes a kind of printing method of collotype with continuous tone reduction original copy.
In concrete the enforcement, adopt and transfer electron colour scanner can comprise the steps: continuously according to the process of the continuous impregnation sheet of original image output Huang, product, green grass or young crops, black four looks
A1, original image carried out the datumization collection and the storage of color separation;
A2, the view data work editor that institute is gathered and stores put in order;
A3, the view data that will edit after putting in order are converted to analog signal, and through amplifying shaping, the sensitization light source control end of electron colour scanner is transferred in input continuously, thereby exports and original copy corresponding photosensitive film.
Nowadays, computer image processing technology has been widely used in printing industry, people can use plurality of devices that image document is converted into can be by Computer Storage and the graphic file of handling, on this basis, according to specification requirement, use image editing software that its color, figure, ratio etc. are done editor's arrangement.Further improvement as the inventive method, change has been made in use to continuous accent electron colour scanner, the direct mode of analog signal is changed into elder generation analog signal conversion is become data signal, after convert data signal the mode of analog signal to, so in the methods of the invention, just can will transfer electron colour scanner only to use continuously as output equipment.
In concrete the enforcement, steps A 1 is described, and that original image is carried out the datumization collection and the storage of color separation is main by following three kinds of methods realization:
