DETAILED DESCRIPTION

[0056] This application provides a printing mesh and a method for screen printing plate making. To make the purpose, technical solution, and effects of this application more clear and explicit, the application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0057] The printing mesh 10 according to the embodiment of the present invention comprises a screen 100 and an erasable material 200. The screen 100 can be completely or partially retained under the action of electromagnetic wave energy, and the erasable material 200 can be removed under the action of electromagnetic wave energy.

[0058] 1 , the screen 100 is a mesh structure made of a material permeable to ink, and has mesh openings 110. The mesh count of the screen 100 can be adjusted appropriately based on the resolution required for the printed image, the ink used, and the printed object.

[0059] The material of the screen 100 can be a metal material. For example, the screen 100 can be made of stainless steel. Alternatively, the screen 100 can be made of nylon, resin, etc. The thickness of the screen 100 is generally less than 300 μm.

[0060] In one embodiment, the wire mesh 100 is a stainless steel wire mesh, which has an absorptivity of less than 40% and a transmittance close to 0% for light below 10.6 μm at room temperature.

[0061] The removable material 200 is a material that is easily removed by the energy of electromagnetic waves. For example, the removable material 200 can be a photosensitive resin material. Alternatively, the removable material 200 can be other polymer materials, such as PU (polyurethane) material or PVC (polyvinyl chloride) material.

[0062] The electromagnetic wave energy acting on the erasable material 200 can be laser, which is used to irradiate the erasable material 200 to remove it. The laser can be of any desired wavelength, including, for example, microwaves, infrared lasers, visible light lasers, UV lasers, X-ray lasers, gamma-ray lasers, etc.

[0063] In the present application, the method for removing the removable material 200 is not limited to laser irradiation. Other methods may also be used, such as using a computer numerical control machine to generate electromagnetic energy to act on the removable material 200. Such a computer numerical control machine can achieve the purpose of removing the removable material 200 by generating high temperature or a light beam (visible or invisible light) to transmit electromagnetic energy to the removable material 200 on the screen 100. For example, the computer numerical control machine can control a needle-shaped heating rod, a beam cutting knife, etc. to act on the removable material 200.

[0064] Preferably, the removable material 200 is a material that can be sublimated by laser irradiation. Alternatively, the removable material 200 can be a material that can be burned to ash by laser irradiation. The laser power is preferably below 100W. For example, desktop laser engravers used at home typically have relatively low power, and their operating power is within this range. Industrial-grade laser cutting machines generally have relatively high power and may damage the screen 100 beneath the removable material 200 during use. Therefore, caution should be exercised when using them.

[0065] It should be understood that when using a laser to remove the removable material 200, the laser can be selected to emit light with a wavelength of 400 nm to 10.6 μm. Furthermore, the screen 100 must be resistant to damage by the laser. In other words, the screen 100 must be able to completely ablate and remove the removable material 200 while remaining intact or partially intact. Partially remaining means that the screen 100 may suffer some damage after laser irradiation, but can still withstand the effects of tension without breaking.

[0066] Typically, a suitable choice is one where the melting point of the screen 100 material is higher than that of the erasable material 200; or the ignition point of the screen 100 material is higher than that of the erasable material 200; or the sublimation point of the screen 100 material is higher than that of the erasable material 200. However, if the laser absorption rates of the two materials differ significantly, the melting point, ignition point, or sublimation point of the screen 100 material can be equal to or even lower than that of the erasable material 200.

[0067] Preferably, polyvinyl alcohol resin is selected as the removable material 200. In this example, since the stainless steel mesh 100 has a lower absorption rate for 400nm to 10.6μm lasers than the polyvinyl alcohol resin, the stainless steel mesh 100 can be completely retained when the polyvinyl alcohol resin is completely removed using laser.

[0068] A printing mesh 10 according to one embodiment of the present invention comprises a paint-permeable screen 100 and an erasable material 200 disposed on the screen 100. The erasable material 200 may be a material that can be applied to the screen 100. Application methods include, but are not limited to, scraping or spraying. After application, the erasable material 200 may be fixed to the screen 100 by drying, air-drying, or air-drying.

[0069] Alternatively, the removable material 200 may be a film-shaped material that can be attached to the screen 100. For example, the film made of the removable material 200 may be attached to the screen 100 by an adhesive.

[0070] The removable material 200 can be completely removed by laser processing, while the screen 100 can be completely or partially retained. During platemaking, the laser can be directly irradiated on a predetermined area of ​​the printing mesh 10 to remove the removable material 200 from the screen 100 in that area, thereby directly forming the desired pattern on the printing mesh 10 and completing the platemaking. Therefore, the printing mesh 10 of the present embodiment is simpler and more convenient to make, and the platemaking process is not complicated, making it particularly suitable for individual platemaking operations.

[0071] Referring to Figure 2 , the removable material 200 can be filled into the mesh 110 of the screen 100. Specifically, the removable material 200 and the screen 100 can be fully bonded to form a single-layer mesh structure. Specifically, the removable material 200 can be applied to the screen 100 and then extruded, ground, or otherwise forced to completely fill the mesh 110 of the screen 100, forming a single-layer mesh structure. This results in a thinner overall thickness for the printed screen 10, making it easier for the user to perform laser engraving.

[0072] If the removable material 200 is a film-like material such as PU or PVC, a possible processing method is to first stick the PU or PVC film on the screen 100, and then heat it to soften the PU or PVC material so that it penetrates into the screen 100 and combines with the screen 100.

[0073] In certain embodiments, referring to shown in Figure 3, dismantling material 200 also can directly be superimposed on screen 100 surfaces, and form dismantling layer 210. In conjunction with shown in Figure 4, dismantling material 200 can be superimposed on the upper surface and / or lower surface of screen 100, and can form dismantling layer 210 on the upper surface and / or lower surface of screen 100. Specifically, dismantling layer 210 can be stacked on the upper surface (as shown in Figure 3) of screen 100. Or, dismantling layer 210 can be stacked on the lower surface of screen 100. Or, dismantling layer 210 can be stacked on the upper surface and lower surface (as shown in Figure 4) of screen 100. Owing to forming dismantling layer 210 on screen 100 surfaces, dismantling layer 210 has played the effect of protecting screen 100, therefore improved the intensity of printing mesh 10 to a certain extent.

[0074] In this example, when the removable material 200 is superimposed on the surface of the screen 100, it is possible that the removable material 200 partially penetrates and fills the meshes 110 of the screen 100. In this case, the removable material 200 has a portion covering the screen 100 and a portion filling the meshes 110. In other words, while the removable material 200 is superimposed on the surface of the screen 100 to form the removable layer 210, it can also partially fill the meshes of the screen 100. In this case, the removable material 200 can be filled in some of the meshes 110 of the screen 100, and / or the removable material 200 can be filled in a portion of the meshes 110 of the screen 100.

[0075] 5 and 6 , in some embodiments of the printing mesh 10, the removable material 200 fully fills each mesh 110 of the screen 100. The removable material 200 also covers the upper and / or lower surfaces of the screen 100 to form a removable layer 210. The addition of the removable layer 210 to the screen 100 protects the screen 100, thereby improving the strength of the printing mesh 10 to a certain extent.

[0076] In the present application, the removable material 200 should be able to adhere tightly to the screen 100. In actual use, the removable material 200 should be able to withstand the friction of a scraper that can transfer liquid (such as ink) to the screen 100 without being damaged.

[0077] As shown in Figure 7, some embodiments of the present application also provide a printing mesh 10, including a screen 100, a first material 400 and a second material 500. The second material 500 covers the surface of the screen 100. The first material 400 is superimposed on the surface of the layer structure formed by the second material 500. The first material 400 is a material that can be eliminated by electromagnetic energy (such as laser). It can also be understood that the first material 400 in this embodiment is the above-mentioned eliminating material 200. The second material 500 is a material that can be eliminated by dissolving in water or other solvents. Specifically, when making a plate, a laser can be used to remove the first material 400 on a predetermined path on the screen, and then a solvent such as water can be used to remove the second material 500 on the path, thereby exposing the screen 100.

[0078] One embodiment of the present application further provides a printing mesh 10, which is a single-layer structure made of a material that can be eliminated by electromagnetic energy (such as the aforementioned eliminateable material 200). During platemaking, laser energy or other energy can be used to directly form the desired pattern on the mesh by locally penetrating the mesh (e.g., punching holes).

[0079] The printing mesh 10 in each embodiment of the present application can be in the form of a single sheet of mesh, or can be made into a roll.

[0080] In some implementations, the edges of the printing mesh 10 may be provided with a hemming structure 300. The hemming structure 300 can wrap around the edges of the printing mesh 10 to prevent them from cutting or puncturing the user. The hemming structure 300 can be formed in a variety of ways. As shown in FIG8 , the hemming structure 300 can be formed by directly folding the edges of the screen 100 inward.

[0081] 9 , the edge wrapping structure 300 may also be formed by wrapping other materials around the edge of the screen 100. In this example, the other materials wrapped around the edge of the screen 100 may be plastic, varnish, cloth, or the like.

[0082] The printing mesh 10 in the embodiment of the present application can be manufactured by the following steps:

[0083] First, a wire mesh 100 is provided, such as a stainless steel wire mesh.

[0084] The screen 100 is then coated with glue. For example, the removable material 200 is a material that can be applied to the screen 100. The removable material 200 is applied to the screen 100 from one side. The removable material 200 can completely or partially fill the mesh 110 of the screen 100. The coating method in this step includes, but is not limited to, preparing the removable material 200 into a semi-fluid state and applying it to the screen 100 by scraping. Alternatively, the coating method can be spraying.

[0085] At this point, there are two situations: When the removable material 200 completely fills the mesh 110 of the screen 100, the screen 100 can be coated without further coating, and a single-layer mesh structure can be directly obtained. Of course, the removable material 200 can also be further coated on the screen 100, so that the removable material 200 covers the surface of the screen 100 to form a removable layer 210. In this case, the printing mesh 10 has a two-layer structure consisting of the screen 100 and the removable layer 210.

[0086] When the removable material 200 partially fills the mesh 110 of the screen 100, the removable material 200 is continuously coated on the screen 100 to form a removable layer 210 on the surface of the screen 100. At this point, the printing mesh 10 has a two-layer structure comprising the screen 100 and the removable layer 210.

[0087] Furthermore, the removable material 200 can be applied to the surface of the screen 100 from the other side of the screen 100 to form a removable layer 210 on the other surface of the screen 100. In this case, the printing mesh 10 has a three-layer structure including the screen 100 and two removable layers 210 disposed on both sides of the screen 100.

[0088] Of course, if necessary, the removable material 200 may be further stacked on each of the removable layers 210 .

[0089] Alternatively, other washable materials or materials that can be removed by other means may be superimposed as needed.

[0090] Furthermore, the printing mesh 10 can be irradiated with a laser as needed to form a printing mesh 10 with a predetermined pattern. This allows users to print desired patterns on various substrates using the printing mesh 10. Of course, the patterns mentioned here are not limited to graphics or images, but also include text, lines, designs combining text and graphics, and other expressive forms of expression.

[0091] When using the printing mesh 10 of the present application for laser plate making, the printing mesh 10 can be irradiated with a laser along a predetermined path, so that the laser can ablate and remove all removable materials 200 on the screen 100 along the predetermined path, thereby forming a printing mesh 10 with a predetermined pattern ready for printing. The predetermined pattern can be uploaded or copied by the user to the laser engraver / cutter, or can be drawn in real time by the user on a terminal device connected to the laser engraver / cutter, such as a computer, tablet, or mobile phone.

[0092] The predetermined path may be a motion path of the laser processing head generated according to the predetermined pattern. The motion path may be generated in a terminal device connected to the laser engraving / cutting machine, or in a processing unit within the laser engraving / cutting machine.

[0093] For users who own a laser engraver / cutter, they only need to place the printed mesh 10 in the processing area of ​​the laser engraver, select the desired pattern on the computer terminal connected to the laser engraver, and start the laser engraver to engrave the printed mesh 10 according to the user's selected pattern. At this time, the trajectory engraved by the laser engraver corresponds to the user's selected pattern. In this way, a screen with the user's desired pattern can be produced. The user can then use this screen to print the desired pattern on various carriers. For example, the user can use a screen printer and a scraper to apply ink on the screen with the desired pattern to print the pattern on a designated object.

[0094] Of course, before this, the printing mesh 10 can be tightened and fixed in a mesh frame to facilitate the user to perform laser engraving operations.

[0095] As shown in FIG. 10 , the present application further proposes a printing screen 20 , comprising a screen frame 201 and the printing mesh 10 of any of the above embodiments, wherein the printing mesh 10 is tautly arranged in the screen frame 201 .

[0096] The mesh frame 201 may be a metal mesh frame, a wooden mesh frame, a plastic mesh frame, etc. The shape of the mesh frame 201 may be rectangular, circular, oval, etc., which is not limited in the embodiment of the present application.

[0097] The circumferential edge of the printing mesh 10 is connected to the inner side of the screen frame 201, so that the printing mesh 10 can be tightened and fixed in the screen frame 201. The printing mesh 10 can be fixed in the screen frame 201 by gluing, or the printing mesh 10 can be detachably connected to the screen frame 201 by screws or other means.

[0098] Referring to FIG11 , a screen printing plate-making method according to an embodiment of the present application includes:

[0099] Step S10: Provide a printing mesh 10. In this step, the printing mesh 10 is any of the printing meshes 10 described in the above embodiments. The printing mesh 10 includes a screen 200 and an erasable material 102 attached to the screen 200. The erasable material 102 can be removed by electromagnetic wave energy, while the screen 200 can remain intact or partially intact under the electromagnetic wave energy.

[0100] Referring to FIG. 11 , the screen printing platemaking method further includes step S20 of providing an energy device 30. The energy device 30 in this step includes an energy head 301 capable of emitting electromagnetic wave energy. The electromagnetic wave energy may be a laser, which is used to irradiate the removable material 102 to remove the removable material 102 from the screen 200.

[0101] In this embodiment, the laser can be of any desired wavelength, including, for example, microwaves, infrared lasers, visible light lasers, UV lasers, X-ray lasers, gamma-ray lasers, and the like.

[0102] Of course, in other embodiments, the method for removing the erasable material 200 is not limited to laser irradiation. Other methods may also be used, such as using a computer numerical control machine to generate electromagnetic energy to act on the erasable material 102. Such a computer numerical control machine can achieve the purpose of removing the erasable material 102 by generating high temperatures or light beams (visible or invisible light) to transmit electromagnetic energy to the erasable material 102 on the screen 200. For example, the computer numerical control machine can control a needle-shaped heating rod, a beam cutting knife, etc. to act on the erasable material 102.

[0103] As shown in FIG13 , in one embodiment, the energy device 30 is a laser engraving machine. Preferably, it is a consumer-grade laser engraving machine, which has a power lower than that of an industrial-grade laser engraving machine. For example, the laser engraving machine is preferably a portable laser engraving machine with a power of less than 100W.

[0104] The laser engraving machine may use a laser with a wavelength of 400 nm to 10.6 μm to engrave the printing mesh 10 .

[0105] When the energy device 30 is a laser engraving machine, the energy head 301 is a movable laser processing head. In one embodiment, the laser engraving machine includes at least processing modes of laser plane processing, laser curved surface processing, and laser screen printing.

[0106] Before moving the energy head 301 along a predetermined motion path on the surface of the printing mesh 10 , the process further includes: selecting a laser processing mode, specifically, selecting a laser plane processing mode or a laser screen making processing mode to operate the printing mesh 10 .

[0107] In the screen printing platemaking method of this embodiment, it is necessary to select a processing mode of laser screen printing or laser plane processing to process the printing mesh 10 .

[0108] Furthermore, before the printing mesh 10 is processed and plate-made, a parameter setting step is also included. Specifically, after the step of selecting the laser processing mode, the step further includes: configuring the power and speed of the laser processing according to the laser processing mode.

[0109] In this embodiment, before using a laser to engrave the printing mesh 10, the engraving parameters of the laser engraving machine must first be determined. The engraving parameters include the power and speed of the laser processing. The engraving parameters can be manually input by the user, for example, by entering specified parameters according to the product manual. The engraving parameters can also be pre-configured with recommended parameters in the laser engraving machine, and the user can directly select the recommended parameters. For example, after the user selects the laser screen platemaking processing mode, the laser engraving machine automatically configures the parameters suitable for engraving mesh platemaking. Alternatively, the laser engraving machine can pre-set the recommended parameters corresponding to different materials, and the user can automatically match the recommended parameters by selecting different materials.

[0110] Since different printing meshes 10 may use different erasable materials 102 or different thicknesses of erasable materials 102, and different erasable materials 102 may have different light absorption, melting points, ignition points, sublimation points, etc., different processing parameters, such as different power and speed, are required for different erasable materials 102 or different thicknesses of the printing meshes 10.

[0111] The power of the laser engraving machine can be below 100W. For example, the laser power of the laser engraving machine can be controlled within a range of 5W-95W. The movable laser processing head can have a moving processing speed greater than 80mm / s. For example, speeds of 100mm / s, 150mm / s, 200mm / s, 500mm / s, or even faster can be achieved. Furthermore, processing speed is generally positively correlated with laser power: higher laser power increases the moving processing speed. Higher power also shortens the time required for the laser head to remain at the processing point on the mesh surface.

[0112] When the laser is engraving the printing mesh 10, the size of the light spot on the surface of the printing mesh 10 is controlled within 0.08 mm2. Preferably, the size of the light spot is smaller than the size of the mesh holes on the printing mesh 10 to achieve a more refined pattern engraving effect and ultimately a more accurate printing effect.

[0113] In one embodiment, the movable laser processing head can have a motion accuracy of less than 0.1 mm. Preferably, the movable laser processing head has a motion accuracy of less than 0.05 mm, for example, 0.01 mm. In this embodiment, high-precision laser platemaking ensures that every detail in the platemaking process is perfectly captured, accurately reproducing everything from tiny text to complex patterns. This provides users with unparalleled detail reproduction capabilities, allowing complex and intricate designs to be perfectly transformed into physical objects. Even under a microscope, every corner of the template is guaranteed to be sharp and every edge is clear and continuous.

[0114] The processing area of ​​the energy device 30 can be located on the workbench of a laser engraving machine, below the laser processing head. Alternatively, the processing area can be located above the laser processing head, in which case the laser beam is directed upward. Alternatively, the processing area can be located to the side of the laser processing head, in which case the laser beam is directed horizontally. Preferably, the processing area is located below the laser processing head on the workbench of the laser engraving machine, with the laser beam directed vertically downward.

[0115] Of course, in other embodiments, the energy device 30 may also be a portable laser marker or other portable laser processing equipment. Alternatively, the energy device 30 includes a bracket and a laser head, with the laser head detachably connected to the bracket. The bracket includes an X-axis track and a Y-axis track, with the X-axis track sliding on the Y-axis track, and the laser head sliding on the X-axis track. During printing, the laser head is moved along the X and Y axes, allowing it to move along a predetermined motion path across the surface of the printing mesh 10.

[0116] Referring to Figure 11 , the screen printing platemaking method further includes step S30: operating the printing mesh 10 using the energy device 30. In this step, the printing mesh 10 is first placed within the processing area of ​​the energy device 30, and then the energy head is moved along a predetermined motion path across the surface of the printing mesh 10 to remove at least a portion of the removable material 102 attached to the screen 10, thereby forming a predetermined pattern on the printing mesh 10.

[0117] Specifically, the energy head moves along a motion path across the surface of the printing mesh 10, transmitting electromagnetic energy to the surface of the printing mesh 10, thereby allowing the electromagnetic energy to act on the removable material 102 of the printing mesh 10. The removable material 102 in the areas of the printing mesh 10 corresponding to the motion path is removed, thereby exposing the screen 200 in these areas, ultimately resulting in a printing mesh 10 with a predetermined pattern.

[0118] The patterns mentioned in the embodiment method of the present application are not limited to graphic images, but also include text, lines, designs combining text and graphics, and other forms of expression with a strong sense of design.

[0119] 11 , in one embodiment, before the step of operating the printing mesh 10 using the energy device 30 , the method further includes step S11 : providing a screen frame, and tightening and fixing the printing mesh 10 in the screen frame.

[0120] In this embodiment, before processing the printing mesh 10, the mesh 10 is first tightened and secured within a tensioning frame. The tensioning frame, holding the stretched printing mesh 10 (or mesh), is then placed within the processing area of ​​the energy device 30. Because the energy device 30 includes an energy head 301 capable of generating electromagnetic wave energy, the electromagnetic wave energy generated by the energy head 301 is transmitted to the surface of the printing mesh 10, thereby processing the printing mesh 10.

[0121] It should be noted that there is no strict order between step S11 and step S20, and the two steps can be performed simultaneously.

[0122] Please refer to FIG12 , in step S30, before the step of moving the energy head along a predetermined motion path on the surface of the printing mesh 10, the process further includes step S31:

[0123] The predetermined pattern is obtained through the terminal device 40 connected to the energy device 30 or the storage unit within the energy device 30. The predetermined pattern can be uploaded or copied by the user to the terminal device 40 or the energy device 30, or can be drawn in real time by the user on the terminal device 40 connected to the energy device 30, such as a computer, tablet, or mobile phone.

[0124] Furthermore, the method further includes step S32: generating a motion plan for the energy head 301 according to the predetermined pattern, wherein the motion plan includes a motion path of the energy head 301. The motion path may be generated in a terminal device 40 connected to the energy device 30, or in a processing unit within the energy device 30.

[0125] This motion path can be used as the motion path of the energy head in the energy device 30 on the X-axis and the Y-axis.

[0126] In one embodiment, in the above step S30, before the energy head is moved along the predetermined motion path on the surface of the printing mesh 10, step S33 is further included:

[0127] The point of action of the electromagnetic wave energy is adjusted according to the distance between the energy head and the printing mesh 10 and / or the thickness of the printing mesh 10 and the thickness of the surface material of the printing mesh 10 .

[0128] For example, the energy device 30 can adjust the focal position of the laser beam based on parameters such as the distance between the energy head and the printing mesh 10 and / or the thickness of the printing mesh 10, the thickness of the surface material of the printing mesh 10, etc. This allows the laser beam to be focused at a predetermined height, allowing it to act at the most appropriate location on the printing mesh 10, achieving the desired removal effect, i.e., removing the removable material 102 without damaging the mesh.

[0129] In this example, the energy device 30 may further include a detection unit capable of measuring parameters such as the distance between the energy head and the printing mesh 10, and / or the thickness of the printing mesh 10, the thickness of the surface material of the printing mesh 10, etc. The detection unit includes, but is not limited to, a laser detection sensor, an X-ray detection sensor, a gamma-ray detection sensor, an ultrasonic detection sensor, and the like.

[0130] It can be understood that there is no strict order between the aforementioned steps S32 and S33, and the two steps can be performed simultaneously.

[0131] The method for screen printing platemaking provided in the embodiment of the present application is that for users who have a laser engraving machine / cutting machine, they only need to place the printing mesh 10 in the processing area of ​​the laser engraving machine, select the desired pattern in the terminal device 40 connected to the laser engraving machine, and start the laser engraving machine to engrave the printing mesh 10 according to the pattern selected by the user. At this time, the trajectory engraved by the laser engraving machine corresponds to the pattern selected by the user. In this way, a printing mesh 10 with the user's expected pattern can be produced, and then the user can use the printing mesh 10 to print the required pattern on various carriers. For example, the user can use a screen printing machine and a scraper to print the pattern on the specified object by scraping ink on the printing mesh 10 with the expected pattern. The method for screen printing platemaking of the present application can realize automated screen printing platemaking, and the platemaking process is simple and fast, and the platemaking time is short. Users can complete it independently at any place, with low platemaking cost, high platemaking efficiency and high precision.
