A kind of supplying structure of ink and printing process thereof of and look web feed printing
Technical field
The present invention relates to a kind of and look web feed printing supplying structure of ink and printing process thereof, belong to printer field.
Background technology
The function of present high-grade printed matter becomes more diverse, as is used for functional ink such as false proof, storage condition detection and increases, and require the extra high special look of saturation degree to increase, so process color a few days benefit increases; It should be noted that the printing chromatic number of little color lump accounts for about 60%, even more in this type of printing.But as shown in Figure 4, existing printing equipment comprises anilox roll 1, carries black groove 2, carries ink roller 3, and during printing, each little color lump takies a look version, causes the printing machine colour cell to increase, and the alignment difficulty increases, the manufacturing cost height.
Summary of the invention
The objective of the invention is to overcome existing polychrome defective workmanship, provide a kind of and look web feed printing supplying structure of ink, have the saving colour cell, reduce the alignment chromatic number, reduce the technique effect of alignment difficulty.
Another object of the present invention provides a kind of and look web feed printing method, uses this method printing to have the efficient height, the characteristics that cost is low.
Technical scheme is as follows:
A kind of supplying structure of ink of and look web feed printing comprises anilox roll, carries black groove, carries ink roller, it is characterized in that: described anilox roll vertically is divided into a plurality of zones by the printing color lump; Each zone is provided with independently one and carries ink roller; This is carried the big or small and corresponding zone of ink roller and is complementary, each carries carrying in the black groove that ink roller places independently, size is complementary, the described roll shaft of carrying ink roller by spring with carry black groove and be connected, thereby make carry ink roller and anilox roll near and keep certain pressure so that printing ink is passed on the anilox roll; Above-mentioned all carry black groove and place in the Da Mo groove bucket.
Describedly carry black groove and be connected in the ink fountain groove.
Described anilox roll
By being set in its surperficial rubber band quiltVertically be divided into a plurality of zones; On the anilox roll at corresponding rubber band place, offer a circular gap, prevent that rubber band from hindering the doctor motion.
A kind of and look web feed printing method is when polychrome printing, with different colours, arranged side by side with page orientation isolated picture and text, cut apart by color lump, and be produced on the same anilox roll, adopt and corresponding ink roller and the Ti Mo groove carried of each color lump, the polychrome picture and text are printed in ink supply together simultaneously.
The beneficial effect of the technology of the present invention is:
1, saves colour cell, reduce the alignment chromatic number, reduce the alignment difficulty, make the purpose that reaches zero error between the process color of merging.
2, reduce production costs, cut down the consumption of energy, expand printing functionality, improve the utilization rate of existing printing machine.
3, the scope of application is wide, can be applied in wide cut reel flexible printing machine, the rotary intaglio printing machine.
4, can be applied in the wide cut printing, realize the local high screen density printing (make-ready protecting wire net function) in the wide cut printing.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described,
As shown in Figure 1-Figure 3, a kind of supplying structure of ink of and look web feed printing, comprise anilox roll 1, carry ink roller 3, carry black groove 4, anilox roll 1 vertically is divided into a plurality of zones by the printing color lump by rubber band 5, and be produced on the same forme, in order to make corresponding anilox roll ink supply zone, be provided with independently in each zone, size and The corresponding area are complementary carries ink roller 3, what each carried that ink roller 3 is positioned at independently, size is complementary with it carries black groove 4, the roll shaft 7 of carrying ink roller 3 by spring 8 with carry black groove 4 and be connected; Carry black groove 4 and be connected in the black groove bucket 2 by fixture block 6, interface arrangment is provided with spring (not drawing among the figure);
Shown in Figure 1 be can and five part picture and text of look be produced on an embodiment on the anilox roll 1; At first, by to can and the part of look is carried out and look, these picture and text are combined into five parts, are divided into five districts by being set in its surperficial rubber band 5.During erection unit, in ink fountain groove 2, place different in width, carry black groove 4 with corresponding five of five parts of forme pattern, and carry black groove 4 with these five and be connected in the ink fountain groove 2, what each put forward the corresponding size of device in the black groove 4 carries ink roller 3, the roll shaft of carrying ink roller 3 is connected on the black groove 4 by spring 8, be used for regulating the distance of shaft centers with anilox roll 1, certain pressure arranged so that carry between ink roller 3 and the anilox roll 1; When anilox roll 1 is rotated, carry ink roller 3 and can obtain power, rotate simultaneously with anilox roll 1, anilox roll 1 is given in ink supply; Adapt therewith, need to offer a circular gap, hinder the doctor motion to prevent rubber band at corresponding rubber band place.
The printing process of the equipment that said structure is formed is, when polychrome printing, with different colours, arranged side by side isolated picture and text with page orientation, cut apart by color lump, and be produced on the same anilox roll, adopt with each color lump to corresponding ink roller and the Ti Mo groove carried, the polychrome picture and text are printed in ink supply together simultaneously.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.
