The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, fig. 1 schematically shows a hardware structure of a decorating machine for performing a decorating method. As shown in fig. 1, the decorating machine 100 includes: a first processor 110, a first memory 120, a printing assembly 130, and a projection device 140; wherein the printing assembly 130 is used to print a target pattern on a substrate and the projection device 140 is used to project a projected image of a fiducial or show pattern on the substrate or a platen of the decorating machine 100. Those skilled in the art will appreciate that the configuration shown in fig. 1 is not intended to be limiting of the terminal, and that the terminal may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components.
Further, referring to fig. 2, fig. 2 schematically shows a structure of a printing machine. As shown in fig. 2, the decorating machine 200 includes a decorating device 21 and a projecting device 22. In some embodiments, when the projection device 22 and the decorating device 21 are an integral structure, the projection device 22 can be welded to the decorating device 21; at this time, since the projection device 22 is fixed to the decorating device 21, when the decorating machine 200 is moved, the relative position between the decorating device 21 and the projection device 22 does not need to be adjusted; however, the vibration generated by the printing device 21 may cause the reference pattern projected by the projection device 22 to be fluctuated. In other embodiments, the projection device 22 and the printing device 21 may be independent of each other, for example, the projection device 22 may be disposed on the ceiling above the printing device 21, or the projection device 22 may be fixed on the floor on one side of the printing device 21; at this time, the reference pattern projected by the projection device 22 is not affected by the vibration of the printing device 21.
The stations of the printing device 21 can be oval or linear. Fig. 2 illustrates an example of a printing machine in which the printing device 21 is an oval-shaped station. The decorating device 21 may specifically include a frame 211, and a printing arm 212, a platen 213, and a printing assembly 214 provided to the frame 211; the printing element 214 is connected to the printing arm 212, and the printing arm 212 drives the printing element 214 to lift or press down by lifting or pressing itself. The printing arm 212 is connected to a driving device (not shown), and the printing arm 212 is driven by the driving device to lift up. The printing arm 212 and the platen 213 are disposed at intervals on the periphery of the frame 211, the platen 213 is located below the printing arm 212, and the platen 213 is slidably engaged with the frame 211.
The printing assembly 214 comprises in particular a doctor blade and a printing frame, and the printing frame is mounted horizontally between the doctor blade, which may be mounted on the printing arm 212 by means of a guide, and the platen 213. The screen in the printing frame is usually made of nylon, glass, polyester, silk or metal mesh, and the mesh of the printing pattern area on the screen is through holes which can be penetrated by ink or dye, but the mesh of the non-printing pattern area is blocked and cannot be penetrated by ink. Scraping the ink or the slurry through an ink leaking area of the pattern to be printed by a scraper so as to print the pattern to be printed on a printing stock; when the doctor blade has finished scraping a frame, the printing arm 212 is raised, thereby lifting the frame and the doctor blade, and the next platen 213 is moved from the previous station to the doctor blade station, thereby printing a pattern on the substrate on the next platen 213.
The projection device 22 is a device that can project an image or video onto a platen or substrate. The projector 22 may specifically include a bracket, a projector mount, and a projector, where the projector mount is mounted to the bracket and the projector is mounted to the projector mount. The projector is used for projecting a projection image of the reference pattern. The projector mount can change the position of the projector in the horizontal direction and/or the height in the vertical direction as desired. For example, the projector may rotate in a horizontal direction about the support. Alternatively, in some embodiments, the bracket of the projection device 22 may be specifically mounted on the frame 211 of the printing apparatus. It should be noted that, in the embodiment of the present invention, both the horizontal direction and the vertical direction are relative to the plane on which the printing device 21 or the projection device 22 is placed.
The number of the projectors can be one or at least two, and the operators in the field can set the projectors according to actual needs. When the number of projectors is one, the projectors may be disposed directly above one of the platens. When the number of the projectors is plural, each projector may be provided right above a different platen; at this moment, operating personnel can adjust the position of the stock of placing on a plurality of platens simultaneously, is favorable to improving stamp efficiency. For example, the number of the projectors may be two, and two projectors may be provided directly above two adjacent platens, respectively, and used to project the reference pattern onto the two platens.
In the related art, in order to ensure that the target pattern is printed at a preset position on the upper printing material, an operator needs to set a corresponding reference pattern for determining the placement position of the printing material on the platen in advance; during the laying up of the substrate, the operator needs to align the substrate with the fiducial pattern. On one hand, the reference pattern is positioned below the printing stock and is easily shielded by the printing stock, so that the sight of an operator is influenced, and the efficiency of aligning the printing stock with the reference pattern by the operator is reduced; on the other hand, since the printing assembly usually needs to print the target pattern on various types of printing materials, various reference patterns need to be arranged on the platen correspondingly, which may result in that reference patterns with various sizes or shapes are distributed on one platen, so that the operator cannot easily find out the correct reference pattern; in addition, as the printing apparatus is used for a longer period of time, the reference pattern on the platen is gradually worn away, and the operator needs to replace the new platen or redraw the reference pattern on the original platen.
Based on this, the embodiment of the invention provides a printing method, which can acquire information of a printing stock to be printed, can call a reference pattern matched with the information of the printing stock, projects an image of the reference pattern to a direction of a platen through a projection device, and controls a printing assembly to print a target image-text on the printing stock if the printing stock on the platen is aligned with the image of the reference pattern. Therefore, the reference pattern can be automatically called according to the information of the printing stock, the position of the printing stock can be determined through the image of the reference pattern projected by the projection device, and the alignment efficiency of printing stock is improved. To facilitate the reader's understanding of the invention, reference will now be made to specific examples.
Referring to fig. 3, fig. 3 schematically illustrates a printing method applied to a printing machine, such as the printing machine 100 of fig. 1, the method comprising the steps of:
s21, obtaining the information of the printing stock to be printed;
in some embodiments, the first processor is capable of obtaining information of a substrate to be printed. The printing stock can be clothing or cut pieces, wherein the cut pieces refer to cut pieces which are not sewn after being cut, and the cut pieces can be cloth pieces specifically. The information of the substrate may be processing order information of the substrate, for example, the information of the substrate may be a color, a shape, and a size of the substrate. When the printing stock is the clothing, the information of the printing stock can be the style and the code number of the clothing, wherein the code number of the clothing comprises an enlarged code, a large code, a medium code, a small code, an enlarged small code and the like. The information of the substrate may also be a target pattern to be printed on the substrate.
S22, calling a reference pattern matched with the printing stock according to the information of the printing stock;
in some embodiments, the first processor may invoke a fiducial pattern matching the substrate based on the information of the substrate. The first processor may specifically select the respective fiducial pattern according to the colour, shape and size of the substrate. To facilitate viewing of the fiducial pattern, the first processor may invoke a fiducial pattern that is a different color than the color of the substrate based on the color of the substrate. For example, when the color of the printing material is black, if the color of the reference pattern is also black, the display effect of the reference pattern is not obvious, so the first processor may select the reference pattern with lighter color, for example, may select the reference pattern with white color.
In some embodiments, the first processor may preset a plurality of reference patterns, and preset a one-to-one correspondence relationship between the information of the printing material and the reference patterns, for example, garments with the same style but different codes correspond to reference patterns with the same shape but different sizes. When the number of the clothes is larger, the first processor can call the reference pattern with larger size; when the number of codes of the garment is small, the first processor may call up a reference pattern having a small size.
S23, projecting the projection image of the reference pattern to one side of the bedplate through a projecting device;
figure 4 schematically shows a projected image schematic of the substrate and fiducial pattern. As shown in fig. 4, the substrate 31 in fig. 4(a) is a cut piece, and the first processor may acquire a reference pattern matching the shape and size of the cut piece in fig. 4(a) and form a projected image of the reference pattern on the platen by the projector. There may be a plurality of fiducial patterns matching the same substrate, for example, the fiducial pattern matching the substrate 31 may be the projected image 32 in fig. 4(b) or the projected image 33 in fig. 4(c), wherein the shape and size of the projected image 32 are the same as those of the substrate 31, and the shape and size of the hollow area in the projected image 33 are the same as those of the substrate 31. The projection may be positioned directly above the platen so that the image of the fiducial pattern is projected vertically onto the platen 34.
In this embodiment, after the projection device projects the image of the reference pattern on the platen, the operator may place the object on the platen and adjust the position of the object based on the projected image of the reference pattern. For example, the worker may place the cut segment 31 in fig. 4(a) on the platen 34 and adjust the position of the substrate 31 on the platen according to the projected image 32 or the projected image 33 of the fiducial pattern; when the projected image of the reference pattern is the projected image 32, adjusting the edge of the substrate 31 to coincide with the edge of the projected image 32; when the projected image of the reference pattern is the projected image 33, the edge of the substrate 31 is adjusted to be the edge of the hollow area with the projected image 33.
Optionally, in some embodiments, the method further includes the following steps:
s23a, projecting at least one projection image of a display pattern on the printing stock through the projection device;
s23b, determining the target pattern according to the display effect of the display pattern on the printing stock.
Typically, the shape, colour and size of the target pattern is pre-set by the operator before printing the target pattern on the substrate. Since the actual appearance of the target pattern on the printing material is affected by the color and size of the printing material, the appearance of the target pattern is affected by the color or size of the printing material. For example, printing a red target pattern on a green garment can affect the aesthetic appearance of the garment. Therefore, in order to determine whether the actual effect of the set target pattern printed on the printing material is beautiful, the operator usually needs to evaluate the effect of the designed target pattern on the printing material by printing the designed target pattern on a piece of two printing materials in advance through a printing machine before mass production. Therefore, raw materials are not wasted, the printing cost is increased, and a large amount of working time of operators is wasted.
Before printing the target pattern, in order to facilitate an operator to evaluate the presentation effect of the target pattern on the printing material in advance, the embodiment may project an image of at least one display pattern on the printing material through the projection device. The first processor can be preset with display patterns with different shapes, colors and/or sizes, and operators in the field can set any different display patterns according to actual needs. The first processor may control the projector to sequentially project the display patterns of different shapes, sizes and/or colors at different positions on the substrate. The operator can determine the display pattern with the optimal presentation effect as the target pattern from the display patterns according to the presentation effect of the display patterns on the printing stock.
Fig. 5 schematically shows the effect of the display pattern on the printed material, as shown in fig. 5(a), the printed material 42 is placed on the platen 41, the first processor can control the projector to project the display pattern 43 on the substrate 42, and the first processor can also adjust the color, size and/or position of the display pattern 43 on the printed material 42, and the adjusted display pattern is shown as the display pattern 43' in fig. 5 (b). The worker can select the target design from the display designs 43 and 43 'according to the effects of the display designs 43 and 43' in 5(a) and 5(b), respectively.
And S24, controlling the printing assembly to print the target pattern on the printing stock.
In this embodiment, after the operator adjusts the position of the substrate on the platen and determines the target pattern, the first processor may capture the target pattern and print the target pattern on the substrate via the printing assembly. In some embodiments, the printing machine further comprises an image capture device, the first processor being capable of determining from the image captured by the image capture device a deviation between the substrate on the platen and the projected image of the fiducial pattern; and if the deviation of the printing stock and the reference pattern is within a preset range, controlling the printing assembly to print the target pattern on the printing stock.
In some embodiments, the first processor may also print the digital pattern on the substrate via a digital printer, which may be disposed above one of the platens of the printer. When the target pattern is complex, the complete target pattern cannot be printed only by the printing screen frame, at this time, the target pattern can be divided into a first pattern area and a second pattern area, and the first pattern area and the second pattern area are printed by the printing screen frame and a spray head of the digital printer respectively; the pattern printed by the digital printer on the second pattern area on the substrate is called a digital pattern. In the embodiment, the screen printing is combined with the digital printing, the advantages of the traditional screen printing can be utilized to print patterns in a large area on a printing stock, the digital ink jet is utilized to print patterns in a small area and in a dotted manner, and the digital printing does not need plate making; the embodiment can make full use of the advantages of digital printing and screen printing, and can form fine and smooth target patterns quickly and efficiently, so that the printing effect is good. In other embodiments, multiple digital printers may be used in cooperation, which requires screen-making.
In some embodiments, the first processor is further capable of acquiring a display pattern, acquiring a model of a preset printing screen frame for printing the display pattern according to the display pattern, and when a worker determines a target pattern in the display pattern, the target patterns with different shapes and sizes correspond to different printing screen frames. The first processor can acquire the model of the printing screen frame corresponding to the display pattern serving as the target pattern, and the model is displayed for an operator, so that the operator can replace the printing screen frame of the printing machine conveniently.
Referring to fig. 6, fig. 6 schematically illustrates a projection correction method applied to a projection apparatus, as shown in fig. 6, the method includes the following steps:
s31, acquiring information of a printing stock to be printed by the printing machine;
