Background
Nowadays, printing technology is more mature, and in order to adapt to more printing carriers, a plurality of printing methods and printing devices are available, for example, UV (ultra or ultra radiation) printing can be used for directly printing patterns on kt plates (a novel material formed by foaming Polystyrene (PS) particles to generate plate cores and laminating the foamed polystyrene particles with surface films), acrylic materials and the like.
However, after related contents (generally, a picture is printed on each material) are printed on a white surface (smooth surface) card type (plate type) material by using the existing UV printer, the contents printed on the material look very strong light-reflecting characteristics, and are not beneficial to identification and verification of the printed contents on the material. Taking a printing resolution of 600dpi as an example, in theory, 600 dots are placed on each inch of length in the transverse direction of the material during printing, and since the material may absorb too much ink, the ink is connected into one piece, and the printing resolution is reduced. In actual operation, materials are matched, the better the ink absorption of the materials is, the more independent ink dots can be placed on each inch, and if the ink absorption of the used materials is general, the situation that adjacent ink dots are fused into a sheet can occur, so that a smooth surface and light reflection are generated, and the printing effect is influenced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, in one embodiment, a UV printing method is presented, the method comprising:
Wherein, UV printing refers to a novel printing process using Ultraviolet light to cure ink, wherein UV (ultra or ultra radiation) refers to Ultraviolet light; the UV printer is provided with a UV lamp and UV printing ink, and during printing, components in the UV printing ink are subjected to cross-linking polymerization reaction under the irradiation of specific wavelength of ultraviolet light emitted by the UV lamp, so that the film forming of the printing ink is accelerated, and the effect of quickly drying the printing ink is achieved. Before printing, an electronic image to be printed needs to be acquired. In traditional printing, the whole electronic image is printed at one time, but because the distance between adjacent pixel points is very short, particularly a high-precision UV printer, the ink printed on the adjacent pixel points is connected together easily, so that the problems of light reflection and the like are caused.
And 104, performing area division processing on the electronic image according to the parameters of the electronic image to obtain a plurality of target printing areas.
The area division processing is to divide the entire print area in the electronic image into a plurality of target print areas. For example, as shown in fig. 2, an electronic image is split in a "farm" type, so that A, B, C and D target print areas can be obtained, or split in other splitting manners, and the purpose is to change original one-time printing into multi-time regional printing. During printing, the A and the D in the diagonal relation can be printed at the same time, and then the B and the C are printed at the same time, so that the phenomenon that adjacent areas are connected together by ink can be avoided.
In one embodiment, the number of target print areas is positively correlated to the size of the electronic image. The larger the electronic image, the more target print areas are obtained by the corresponding division. For example, when the image size is 256 × 256, the image may be divided into 6 target print areas, and when the image size is 1024 × 1024, the image may be divided into 96 target print areas.
At step 106, the printing order of each target printing area is determined.
Wherein, after the area division is completed, the printing order of each target printing area needs to be determined. In one embodiment, each target print region corresponds to a different print order. In another embodiment, two or more target print areas may correspond to the same print sequence, and the same print sequence is printed simultaneously, for example, if there are 5 target print areas, three of the target print areas may be printed simultaneously as the first print sequence, and the other two target print areas may be printed simultaneously as the second print sequence, then three of the target print areas may be printed simultaneously, and then the other two target print areas may be printed simultaneously.
In one embodiment, the number of target print areas printed simultaneously is positively correlated with the total number of target print areas. The greater the total number of target print areas, the greater the corresponding number of simultaneously printed target print areas. For example, if the total number of target printing areas is 10, 5 target printing areas may be printed at the same time, and if the total number of target printing areas is 5, 2 target printing areas may be printed at the same time. For example, the electronic image to be printed is divided into 20 target printing areas, and then the target printing areas are sequentially printed four times, the number of the target printing areas printed each time can be the same or different, which is equivalent to that the 20 target printing areas are divided into 4 types to be sequentially printed.
Furthermore, when determining the printing sequence of each target printing area, the current printing time situation can be combined, and if the time is short, a plurality of printing can be set simultaneously, namely, the time is shortened by reducing the printing times.
And step 108, printing the electronic image according to the target printing areas and the printing sequence of each target printing area.
After each target printing area and the corresponding printing sequence are determined, the electronic image can be printed according to the target printing areas.
The printing area is split into the target printing areas, and the target printing areas are respectively subjected to subarea printing according to the determined sequence, so that the successively printed target areas can be fully solidified, ink connection is avoided between the target areas after subarea printing, the problem that ink of the whole image is connected due to one-time printing is solved, the smooth surface and the reflection of light after image printing are reduced, and the printing effect is improved.
As shown in fig. 3, in one embodiment, the area division processing of the electronic image includes:
at step 302, parameters of the electronic image are obtained, the parameters including a size of the electronic image.
The size of the electronic image refers to the product of the number of single-row or single-column pixel points in the horizontal and vertical directions in the electronic image, for example, 1200 pixel points are arranged in the horizontal single-row and 2000 pixel points are arranged in the vertical single-column of a certain electronic image, and then the size of the electronic image is represented as 1200 x 2000. In this embodiment, the ratio of the number of pixels in a single row or a single column in the horizontal and vertical directions in the electronic image is obtained.
And step 304, determining a corresponding printing coordinate matrix according to the parameters of the electronic image.
The method comprises the steps of obtaining a single-row or single-column pixel number in the horizontal direction and the vertical direction of an electronic image, determining a corresponding printing coordinate matrix according to the number ratio of the single-row or single-column pixel number in the obtained electronic image, wherein the printing coordinate matrix is a schematic matrix which is used for area division and has a specification similar to that of the electronic image, and the purpose is to abstract an area where the pixels are located in the electronic image, and only a specific correlation proportion coefficient is needed, and how many pixels are needed. For example, a 1200 × 2000 electronic image may correspond to a printing coordinate matrix of 3 × 5, 6 × 10, etc., where the numbers in "3 × 5, 6 × 10" are all expressed as non-specific scales and only represent proportional and equal division relationships, for example, "3 × 5" represents a ratio of the length to the width of the printing coordinate matrix of 5:3, and divides the length and the width into 5 equal parts and 3 equal parts, respectively.
And step 306, carrying out region division processing on the pixel points in the electronic image according to the printing coordinate matrix.
After the print coordinate matrix is determined, the print coordinate matrix represents a schematic matrix of a distribution area of pixel points in a corresponding electronic image, and the division of the print coordinate matrix is equal to the division of the electronic image, that is, the division of the pixel points in the electronic image.
The printing coordinate matrix is determined according to the size of the electronic image, the real number of actual pixel points is not considered, so that the dividing process is simplified, the dividing process is clearer and clearer, and the final printing effect is improved.
As shown in fig. 4, in an embodiment, the performing area division processing on the pixel points in the electronic image according to the printing coordinate matrix includes:
The preset division shape model is a shape model used for splitting the printing coordinate matrix, and the shape model comprises a shape and a size. The shape of the target print area thus separated is the same as the shape model used, and the size thereof is the same as the size of the shape model used. One or more division shape models may be used. The shape of the preset division shape model can be a regular shape, such as a triangle or a square, or an irregular shape, such as a concave shape, a convex shape, or other irregular polygons, such as the shape shown in fig. 6.
For example, if the print coordinate matrix is 16 × 16, a square with a side length equal to 4 equal parts in the print coordinate matrix may be used for splitting, or a split shape model with other sizes or other shapes may be used for splitting.
And step 404, decomposing the printing coordinate matrix according to a preset division shape model.
After the type, size and number of the division shape model are determined, the determined division shape model is used for decomposing the printing coordinate matrix.
And 406, matching the decomposed printing coordinate matrix with the pixel points in the electronic image to obtain a target printing area where each pixel point is located.
The printing coordinate matrix is a schematic matrix without considering the actual number of the pixels, and after the target printing area is determined in the printing coordinate matrix, the target printing area is matched with the pixels in the electronic image to obtain the pixels to be printed in each target area in the printing coordinate matrix.
The printing coordinate matrix is split by utilizing the preset division shape model, and different shape modules can be selected by combining with actual conditions, so that the optimal printing effect is achieved.
As shown in fig. 5, in one embodiment, the preset division shape model is a model according to which the print coordinate matrix is decomposed, and includes:
When the adopted division shape model is a single type, for example, as shown in fig. 6, a part in which a is located is a target printing area divided by one division shape model, the division shape model is spliced and split in an area for printing a coordinate matrix according to the shape characteristics of the determined division shape model, and then a plurality of target printing areas with the same shape are obtained, as shown in fig. 7.
The shape characteristics of the adopted division shape model cannot guarantee that the whole area of the printing coordinate matrix is just split, the part of the whole area is usually left at the edge, the rest part can be supplemented by randomly dividing or extending the currently adopted division shape model, the division request shown in fig. 8 is finally obtained, and a target printing area is encircled by each thick solid line.
By adopting a shape division model to split the printing coordinate matrix, the splitting can be rapidly completed, and the efficiency of the whole printing process can be improved.
As shown in FIG. 9, in one embodiment, determining the printing order for each target print region includes:
When the printing sequence of each target printing area is determined, the electronic image is divided into a plurality of printing areas by the divided target printing areas, and the position shapes of the target printing areas are changed along with the change of the division rule, so that a specific one of the target printing areas is not required to be determined as the first printing. In the embodiment, a target printing area is randomly determined as the area printed firstly; of course, the fixed position target printing area may be set as the area to be printed first, as shown in fig. 10, the area where "1" is located in the drawing is determined as the first target printing area, and the printing sequence of the area is marked as the first printing sequence, i.e., the first printing, and so on.
When the printing sequence is determined, the mutual interference of target printing areas printed twice adjacently is ensured to be minimum as much as possible; specifically, the determined first target print area is used as a central print area, and adjacent target print areas in contact with the central print area are acquired, where contact means sharing of dots or lines between divided shapes of the target print areas, and as shown in fig. 10, there are 8 adjacent target print areas in contact with the determined central target print area.
As shown in fig. 10, of the 8 adjacent target print areas, 4 of them are shared by dots and 4 are shared by lines, and the contact degrees shared by the 4 lines are the same, and are all 4 equal lengths.
Step 908 is to mark the printing sequence of each adjacent target printing area according to the magnitude of the contact degree, wherein the printing sequence is positively correlated with the magnitude of the contact degree, and the printing sequences corresponding to the adjacent target printing areas with the same contact degree are the same.
The target areas printed twice adjacent to each other are made to have the smallest mutual influence, so that the printing sequence of each target printing area is determined according to the contact degree, and finally the printing sequence of the adjacent target printing areas determined according to the contact degree is shown in fig. 11, wherein the number in each target printing area represents the printing sequence. In one embodiment, the printing order may be further marked for a plurality of target printing areas having the same degree of contact, as shown in fig. 12, in which the third printing order determined in fig. 11 is further divided into a third printing order and a fourth printing order.
The above process is repeated with the adjacent target printing areas as the central target printing areas, respectively, and the printing order of all the target printing areas is determined according to the degree of contact. In one embodiment, the printing order marking rule shown in fig. 12 is followed to finally obtain the complete printing order marking as shown in fig. 13.
The printing sequence of each target printing area is determined according to the contact degree between the target printing areas, so that the interference between two adjacent times of printing is avoided to the maximum extent, and the printing effect is improved.
In one embodiment, printing an electronic image according to target print areas and a print order for each target print area includes: acquiring a preset time interval between two adjacent prints; and printing the electronic image according to the printing sequence of each target printing area and the preset time interval.
The UV printing is substantially the effect of curing UV ink by ultraviolet light, so that the printing is performed immediately, and the curing requires a certain time, and although the time is short, the curing also requires precise control, and the corresponding printing time interval is specifically set according to the printing requirement and the material characteristics.
The curing can be fully carried out after each printing, and the final printing effect is improved.
In one embodiment, performing a region division process on the electronic image to obtain a target print region includes: obtaining the value of each pixel point in the electronic image, wherein the value of the pixel point comprises: any one of a gradation value, an RGB value, and a CMYK value; and carrying out area division processing on the electronic image according to the value of each pixel point to obtain a plurality of target printing areas.
When the electronic image is partitioned, the electronic image can also be directly and randomly partitioned, specifically, the gray scale value 0-255 is partitioned into a plurality of intervals according to the values of the pixel points of the electronic image, such as the gray scale value, and the area where the pixel points falling into the corresponding interval are located is used as the target printing area. Or dividing the color image according to RGB values or CMYK values, wherein the RGB values and the CMYK values are values of pixel points in different color modes. RGB is a luminescent color pattern, and CMYK is a printing color pattern. Above-mentioned no matter which kind of mode, all directly divide according to the value of pixel, and divide through the value of pixel, be favorable to improving the speed of dividing for print more fast. The printing sequence is related to the number of times of printing, for example, the printing is divided into 4 times of printing, then the value of the pixel point can be divided by 4 to obtain target printing areas with remainder of 0,1,2 and 3, which is equivalent to dividing the target printing areas into 4 types, for example, the target printing area with remainder of 1 is printed first, then the target printing area with remainder of 3 is printed, then the target printing area with remainder of 0 is printed, and finally the target printing area with remainder of 2 is printed.
