The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Rainbow typography of the present invention may further comprise the steps:
Step 1: design and printing shading A;
Step 2: said shading A is divided into shading B and shading C, and exports and process galley B and galley C, wherein said shading B and/or said shading C are rainbow printing shading;
Step 3: said galley B and said galley C are respectively installed on the predefined different printing unit;
Step 4: after debugging said printing element, through said galley B and said galley C with said shading B with said shading C chromatography be in the same place.
Because said shading B and said shading C separate; So can be respectively before printing, carry out lines from coarse to fine or/and by lines on the spot to the rainbow printed design of modulating net variation; Or only one of them is carried out the rainbow printed design, and output and printing down again, last chromatography is together.On the product that prints, the effect that is similar to the rainbow gradual change of said shading B and said shading C is different.The printing of existing mechanical rainbow can only laterally or vertically have the rainbow effect, and the invention solves the single problem of this rainbow form.
In the present invention, said shading A can be for using the false proof shading of false proof software design, and said shading A can make different formal arguments as required, can not have influence on the operation of each technical process of back.When cutting apart said shading A, can on said shading A, dig out said shading C, it is said shading B that said shading A goes up rest parts.Can use false proof design software that said shading A is cut apart, obtain two different said shading B and said shading C.As shown in Figure 1, the frame of broken lines among the figure is represented cut-out, and shading B area occupied ratio is big, so shading B keeps the shape outward appearance of shading A basically.The shape of the shading C that splits in the cutting procedure can be regular geometric shapes, plant shape, animals shaped or personage's shape etc.; Such as selecting to use annular, oval ring, square and other required forms as required.
Shading B and shading C can select to realize with traditional mechanical rainbow printing the whole structure of rainbow printing, the rainbow design before also can printing; But the shape of the part that is hollowed out among the shading B and the shape of shading C will keep identical, could realize the rainbow printing effect of the preceding design of seal like this, such as annular rainbow effect, square rainbow effect etc.Shading B that is split and shading C maintain the basic pattern features of shading A.Under the constant prerequisite of basic pattern features; Shading B and shading C can be designed to lines on demand; These lines are to have shading from coarse to fine and that changed to frequency-modulation halftone dot by lines on the spot; Before seal, in output and the printing process, realize that mechanical rainbow printing is compound with three kinds of effects of design rainbow printing.
In the output procedure of said shading B, shading C; Each shading and pattern are selected corresponding way of output output by characteristic separately respectively; Just lines output on the spot of lines shading faithfully; Frequency modulation rainbow effect part is just with the fm screening parameter output of corresponding suitable typography, and each edition printing down on request, publication is to be printed.Be illustrated in figure 2 as the scheme flow chart of a kind of embodiment of the present invention, wherein shading B is the shading that mechanical rainbow prints, and shading C is the rainbow shading through design before the seal, and shading B and shading C branch is opened the output printing down then, and last chromatography together.
In the printing set-up procedure, the forme of each rainbow effect by separately in advance designing requirement be contained on the different printing elements and print.Such as, shading B be design do traditional mechanical rainbow printing effect, then the forme with shading B is installed on the printing element that has mechanical rainbow printing effect, and each train of mechanism of mechanical rainbow printing element is set on request; Forme with design rainbow printing effect before other seal is installed in respectively on the common printed unit again, and the print system of good each printing element of debugging etc. are to be printed.In printing process, the forme of all rainbow effects needs strict chromatography together, chromatography skew precision should be controlled at ± 0.15mm in, to reach best rainbow printing effect.
After being completed for printing, the semi-finished product that print out are carried out post-press finishing, according to the effect of design before the seal, the finished product of the combination rainbow printing effect of design rainbow effect before just can obtaining including traditional mechanical rainbow printing effect and printing.Its finished product is the main body with traditional mechanical rainbow effect, and the rainbow effect of design is for auxiliary before the seal; The rainbow effect of design can increase annular rainbow effect, square rainbow effect, frequency modulation rainbow effect etc. as required before the described seal.So the present invention also proposes a kind of print product, this product adopts the printing of aforesaid rainbow typography to form.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
