The uniformly distributed ridge walls are distributed on the single page wholly or partially.
The uniformly distributed ridge walls are integrally rectangular, square, circular, oval, rhombic or irregular.
The three-vision printing method of the offset press and the product have the advantages that:
1. the UV printing mode is utilized to carry out multiple curing printing, ridge walls which are uniformly distributed are formed on a single sheet of paper, the effect of different patterns in three visual directions is formed by combining the height of the ridge walls, the gaps between the adjacent ridge walls and the patterns on the left side, the right side and the top surface of the ridge walls, the expression forms of the single sheet of paper are enriched, and the interestingness is increased;
2. the whole or partial coverage of the uniformly distributed ridge walls on the single-page paper can be flexibly realized through a UV printing mode, and the change and the conversion of different positions, different directions, different shapes and different patterns can be formed in the single-page paper or the made booklet by matching with the overall distribution shape of the uniformly distributed ridge walls, so that the display content is enriched, and the vividness in the using process is improved;
3. the printing and forming process is simple, convenient, flexible and quick, the content and the expression form of the existing paper product are greatly enriched, the application range is expanded, and a new application field is created.
Detailed Description
Taking three patterns in left, right and forward three-view directions on a single sheet of paper as an example, the three-view printing method of the offset press comprises the following specific steps:
step 1, determining the height of a three-dimensional printing ridge wall and the gap between adjacent ridge walls on a single sheet of paper according to the required left side, right side and forward visual angle, and evenly cutting the patterns to be printed in three directions into a plurality of image strips through an image processing technology, wherein the width of each image strip is equal to the width and height of the required three-dimensional printing ridge wall.
Through setting up the pattern of waiting to print of three directions, including the pattern of waiting to print of ridge wall left side direction of height, ridge wall right side direction of height and ridge wall top width direction, can form three directions of looking and have three different patterns, richen the expression form and the expression content of pattern. Of course, the length of the figure strip needs to be matched with the length of the required three-dimensional printed ridge wall, so that the whole pattern coverage of the ridge wall is completed.
And 2, carrying out image segmentation processing on the picture strips by using an image processing technology to form a printing pattern in the width and height directions of the required three-dimensional printing ridge wall.
The pattern format can be stored for the pattern which is divided into strips according to the subsequent required UV printing mode by the image dividing processing in the image processing technology, so that the printing of the printed patterns on the side surface and the top surface of the ridge wall is finished while the ridge wall is formed in the subsequent UV printing process, and the printing and forming process is simpler, more convenient, more flexible and faster.
And 3, carrying out multiple times of curing printing on the single-page paper by adopting a UV printing mode to form uniformly distributed ridge walls, and correspondingly printing to form a left side printing pattern of the ridge wall, a right side printing pattern of the ridge wall and a top surface printing pattern of the ridge wall.
In the embodiment, the uniformly distributed ridge walls are distributed on the paper in a local mode, meanwhile, the uniformly distributed ridge walls are integrally square, and the left side printed pattern, the right side printed pattern and the top surface printed pattern of the ridge walls can form the effect of local three-view direction different patterns on a single page of paper. The height of the ridge walls which are uniformly distributed and the gaps between the adjacent ridge walls can be determined according to the required visual angle range of the ridge walls on the left side and the right side, so that the required three-view direction patterns are formed in a matching manner.
Of course, the ridge walls which are uniformly distributed can be in a rectangular shape, a circular shape, an oval shape, a rhombic shape or an irregular shape, and the ridge walls which are uniformly distributed on the single-page paper can be in a whole distribution or in a local distribution of a plurality of blocks, so that the expression forms of the patterns are enriched, and the interestingness is increased.
And 4, finishing the subsequent normal cutting process to form the required single-page paper with the three-view effect.
The product manufactured by the offset press three-dimensional printing method comprises single-page paper, wherein ridge walls formed by UV three-dimensional printing and multiple printing and curing are distributed on the single-page paper. The ridge walls are uniformly distributed on the single-page paper in a local mode, and the uniformly distributed ridge walls are square as a whole. The height of the ridge wall and the clearance between the adjacent ridge walls are set through the visual angle ranges of the left side and the right side required by the single-page paper, and meanwhile, corresponding patterns are printed in the height direction of the left side of the ridge wall, the height direction of the right side of the ridge wall and the width direction of the top surface of the ridge wall, so that three different patterns can be formed in the three-view direction, and the content and the expression form of the single-page paper are greatly enriched.
Of course, the uniformly distributed ridge walls can also be distributed on the single-page paper in a mode of overall coverage, and the whole uniformly distributed ridge walls can also be in a rectangular shape, a circular shape, an oval shape, a rhombic shape or an irregular shape.
Of course, the single page paper can be processed into a booklet, so that different conversions and changes of patterns in different directions on different single pages and different positions in the album are formed, the expression form of the booklet is enriched, and the vividness of turning over is improved.
