[0045] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects proposed according to the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0046] The present invention provides a method for printing with a flexible photosensitive gravure printing plate, such as Figure 1 As shown, the gravure printing method comprises the following steps:

[0047] S1, making a rough board surface. The plates used for general gravure printmaking are mainly copper plates, zinc plates, aluminum plates, plastic plates, hemp glue plates and resin plate materials, etc., and the acid rot process is often used in combination with the selected copper plates, aluminum plates, zinc plates, steel plates and other metal plates for the production of gravure printmaking. In addition to using the acid rot process in combination with metal alloys to make gravure printmaking, in the present invention, a density board with a certain hardness is selected, and a process combining a flexible photosensitive material with a hard photosensitive material is used to make the printing plate of the gravure printmaking, and the two sides of the rough board surface are horizontal rough board surfaces. For example, in this embodiment of the present invention, a density board is selected, and considering the continuity of the gravure printmaking image and the artistic effect of rendering, this embodiment uses an Ausone board made of natural trees as raw materials as a material to make a horizontal rough board surface. Generally, the Ausone board is a medium-density large core board, and its natural source wood material ensures the continuity of the cellulose in the board. The fiber of the Ausone density board is soft, and has a certain hardness, and the moisture absorption and deformation are controllable, and the internal bonding strength is high. In this embodiment, a suitable thickness of Osson board material is generally selected. Based on the size and printing process of plate making and printing plate, as well as the printing art effect, this embodiment selects a 3mm thick Osson board 1 to ensure that the board surface of the Osson board 1 material is a horizontal board surface. When making a horizontal rough board surface, the board surface of the Osson board 1 is firstly polished to make the board surface of the Osson board 1 have no obvious protrusions, keep it basically flat, and be in a horizontal state. Then the flat board surface is polished and roughened to keep the preset roughness on the flat board surface of the Osson board 1. For example, the surface roughness Ra of the Osson board 1 is between 0.21 and 0.48um through the polishing and roughening process. It can be easy to adhere to the adhesive when the board surface is basically smooth and flat. The Osson board is environmentally friendly and light in color, which meets the requirements for the production and printing of works of art. It is convenient to obtain materials, easy to process and not costly.

[0048] In an embodiment of the present invention, the following steps are also included when making a horizontal rough board surface: first, one side of the rough board surface is fixed, and the other side is polished to the edges of the rough board panel at any angle within the range of 30° to 60° using cutting and grinding equipment, such as the edge 11 of the Osson board at an angle of 45°, and the edge joint 12 of the Osson board, so that when the base plate of the Osson board 1 is used for printing later, it will not damage printing auxiliary materials such as felt, and printing machinery and equipment. After the rough board surface of the Osson board 1 and the edge 11 of the Osson board at an angle of 45° are made, the front and back sides of the rough board surface are continuously coated with protective paint. For example, the protective paint can be selected from environmentally friendly shellac varnish. The lacquer product of shellac varnish, a mixture of shellac, solvent, filler and lubricant, has natural color and good transparency, natural beauty, can effectively protect the surface roughness of Oson board 1, and enhance the hardness and durability of the Oson board surface, avoid fading, decay and moisture, and can solidify the rough board surface of Oson board 1, which is beneficial for waterproofing and anti-ink corrosion.

[0049] like Figure 2 As shown, S2, coating a photosensitive adhesive for gravure printing a target image on the screen, developing the target image on the frequency modulation film to obtain a screen with the target image (see Figures 3 to 5 ). The process of coating the photosensitive adhesive for gravure printing the target image on the screen includes: selecting a 300-mesh screen 22, fixing the screen 22 on a screen frame 21 of a preset size to form a screen 2, wherein the screen 22 can have any mesh number in the range of 250 to 300 meshes. The screen 22 in the screen 2 is a horizontal mesh, and the state when it is erected is shown in FIG. Figures 3 to 5 As shown in , based on the screen coating method, the two plate surfaces on the screen plate 2 of the screen are repeatedly scraped to maintain a preset thickness of flexible photosensitive adhesive 24 for gravure printing of the target image in a dark environment. For example, a coating brush 23 can be used for scraping. After each scraping of a certain thickness of flexible photosensitive adhesive, the flexible photosensitive adhesive to be applied absorbs water and dries to form a solidified photosensitive adhesive 241. The flexible photosensitive adhesive is repeatedly scraped on the surface of the dried photosensitive adhesive again until it is dry. This is repeated for at least 6 times, so that the adhesive film of the dried photosensitive adhesive maintains a certain thickness in the range of 1 to 3 mm, which is convenient for storing a corresponding amount of ink according to the actual ink application amount of the target image when gravure printing the target image. As shown Figures 3 to 5 As shown, the target image is a first target image 31 and / or a second target image 32, wherein the amount of ink in the first target image 31 is not greater than the amount of ink in the second target image 32. For example, the screen 22 has scale lines, and the target image in the screen 2 can be divided into a plurality of regular or irregular screen printing areas 221, which is convenient for calibrating and adjusting the position or area of ​​the target image.

[0050] In the embodiment of the present invention, the target image on the FM film is developed to obtain a screen with the target image, including: the target image designed and rendered by an imaging device such as a camera or a video camera, and a graphics device such as a computer is printed on the FM film 4 through a certain modulation process to obtain the FM film 4 with the target image. The intaglio screen 2 and the positive side of the FM film 4 with the film surface are matched along the two board frame sizes, and then the film surface on the FM film 4 (i.e., the positive side with the image) is made close to the flat surface of the silk screen 2, and the two are seamlessly attached and fixed together to form a bonded whole, and the FM film 4 and the screen 2 are fixed at the edge of the bonded whole with a transparent tape, so that the target image can better retain the accuracy of the FM film 4.

[0051] In an embodiment of the present invention, the bonded whole is placed in an exposure device to expose the photosensitive adhesive 241 solidified in the screen 2 bonded with the frequency modulation film 4. Specifically, the tolerance of the plate exposure machine is adjusted based on the mesh number of the screen 2, the type of photosensitive adhesive (water-based or oily), the coating thickness, and the ink application amount of the target image. For example, when the mesh number of the screen 2 is larger, the type of photosensitive adhesive is oily photosensitive adhesive, the coating thickness is thin, and the ink application amount of the target image is small, the tolerance of the plate exposure machine can be adjusted to a small tolerance range. On the contrary, the tolerance of the plate exposure machine is adjusted to a large tolerance range. Generally, the exposure time under a stronger ultraviolet lamp is between 30 seconds and 2 minutes; while under a weaker ultraviolet lamp, a longer exposure time of about 3 to 5 minutes is required. In addition, the tolerance of the plate exposure machine is finely adjusted according to the specific coating thickness value and / or the ink application amount value of the target image to adapt to the fine exposure and development of the target image. The present invention develops the target image on the frequency modulation film 4 on the screen plate of the silk screen by exposing the photosensitive adhesive coated on the silk screen, thereby obtaining the screen plate 2 of the gravure print with the target image on the frequency modulation film 4.

[0052] In an embodiment of the present invention, as another implementation method, when the screen printing is performed one plate and one color by stencil printing, the adhesive layer of the solidified photosensitive glue 241 is usually thin, and the thickness generally does not exceed 1.5 mm. After the frequency modulation film is exposed or exposed, the fineness of the halftone target image obtained is not high and appears thin. The one-time screen printing does not reflect the fine effect of the screen printing applied to the gravure print. The present invention avoids the complex process of obtaining the gravure printing plate by engraving or acid etching process by combining the frequency modulation film sheet 4 with the screen 2 and exposing and developing the solidified photosensitive glue 241 on the screen 2.

[0053] In an embodiment of the present invention, Figure 5As shown, exposing the photosensitive adhesive coated on the screen includes: exposing the photosensitive adhesive coated on the screen to a first preset time based on the exposure condition; wherein the first preset time includes 1 to 5 minutes. wherein the exposure at the first preset time is determined according to the type of illumination under different illumination environments, and different degrees of exposure intensity at different powers. For example, multiple exposures are generally used to correspond to different thicknesses of the adhesive layer on the gravure print corresponding to the solidified photosensitive adhesive 241. For example, a strong ultraviolet exposure can be performed during the first preset time (such as within the range of 1 to 5 minutes); and then the light type is changed to perform a weaker double U-shaped 70W non-ultraviolet uniform light source exposure with a color temperature of about 4000K during the second preset exposure (such as within the range of 5 to 15 minutes). In an embodiment of the present invention, the layers and fineness of the image on the solidified photosensitive adhesive 241 are obtained through long-term exposure and different degrees of exposure under different illumination environments, such as different screen colors, light source types, light intensity, exposure ambient temperature, thickness of the solidified photosensitive adhesive 241, and exposure distance and angle. The present invention selects a yellow silk screen, adopts ultraviolet irradiation, and adjusts the ambient temperature of the exposure operation within the range of 22 to 28°C. The optimal temperature can be controlled at a constant temperature of 25°C. When the relative humidity is controlled at 50% to 70%, the intensity, distance and angle of the exposure are adjusted to expose the solidified photosensitive resin 241 for the above-mentioned adapted time in a graded exposure manner, so that the thickness of the glue layer on the solidified photosensitive resin 241 presents different thickness height differences based on the different levels and different fineness of the pattern on the target image, thereby overcoming the influence of insufficient exposure or excessive exposure on the target image on the screen 2, and making the solidified photosensitive resin 241 after exposure have the fine artistic beauty of the target image of the gravure print.

[0054] In the embodiment of the present invention, during the process of printing and exposure, the solidified photosensitive glue 241 can be exposed for a long time (such as exposure time of 2 to 9 minutes) in a light source environment of about 5000K using a double U-shaped high-power color temperature, so that the fine details of the target image in the frequency modulation film 4 are completely expressed in the structural form of the gravure print on the solidified photosensitive glue 241, avoiding the influence of the print creator in the environment of ultraviolet light radiation, and improving the safety of the gravure printmaking plate making process. In addition, in the exposure stage, the solidified photosensitive glue 241 smeared on the silk screen can be directly exposed by digital projection amplification, and the diazo photosensitive solution DM-I ratio photosensitive agent is used for development and production, so as to obtain a small and medium-sized picture size that meets the requirements of the fineness of the target image. Among them, developing the target image on the frequency modulation film to obtain the screen with the target image also includes: after obtaining the screen 2 of the gravure print with the target image on the frequency modulation film 4, performing a second preset time exposure process on the screen 2. Before the second preset time exposure, it is emphasized that the frequency modulation film 4 and the screen 2 are in good contact, and the dot change rule is consistent. During exposure, the original plate and the plate material are in close contact and uniform, and the exposure is carried out by a high vacuum suction sealing method, so that the screen 2 and the refined target image on the screen 2 are further reinforced.

[0055] S3, such as Figure 6 As shown, the rough plate surface and the screen are pasted to a fitting state to obtain a target printing plate for gravure printing.

[0056] In an embodiment of the present invention, before pasting the rough plate, the frequency modulated film 4 is first removed to obtain a screen 2 with a solidified photosensitive adhesive 241 of a target image. Among them, pasting the plate surface and the screen to a fitting state to obtain a target printing plate for gravure printing includes: spraying the rough plate surface and the screen surface with the target image with spray glue and then standing for a third preset time; wherein the third preset time can be selected as any time in the range of half a minute to 5 minutes as the standing time. Paste the rough plate surface and the screen 2 with the target image to a fitting state, and keep the compacted state. To keep the above-mentioned bonding structure in a compacted state, a soft cloth can be used to place it, and the air in the bonding part can be gradually squeezed out. The duration of the compacted state can be set according to the actual situation, such as compacting for at least 24 hours, and standing for a treatment in a compacted state at the upper and lower parts.

[0057] In an embodiment of the present invention, pasting the rough plate surface and the screen to a pasted state to obtain a target printing plate for gravure printing further includes: leaving the pressed pasted rough plate surface and the screen to stand for a fourth preset time until they are completely dried. For example, in the compacted and standing state, the fourth preset time is at least 24 hours to wait for them to be completely dried. As a preferred method, it can be carried out at room temperature to avoid the occurrence of flowery or smeared plates.

[0058] In an embodiment of the present invention, Figure 7 As shown, pasting the rough board surface and the screen plate to a pasted state to obtain a target printing plate for gravure printing also includes: when pasting the rough board surface and the screen plate surface with the target image, a preset length of the screen plate surface is reserved around the rough board surface, and after cutting the screen plate surface, the reserved preset length of the screen plate surface is mounted on the back of the rough board surface. Figure 8 As shown, the first target printing plate 41 includes: an Osson plate edge portion 11, an Osson plate edge joint portion 12, a solidified photosensitive adhesive 241 and a first target image 31 (such as Figure 8 The intaglio print "ABC" image in Figure 1). Fig. 9 As shown, the second target printing plate 42 includes: an Osson plate edge portion 11, an Osson plate edge joint portion 12, a solidified photosensitive adhesive 241 and a first target image 32 (such as Fig. 9 Intaglio print images in Figure 7 In the embodiment, the preset length value on the screen 2 corresponding to the screen edge portion 25 can be any length value in the range of 2 cm to 7 cm.

[0059] S4, such as Fig.10 As shown, a target image is printed on a target printing plate based on ink and / or plate wiping methods.

[0060] In an embodiment of the present invention, printing a target image on a target printing plate based on ink and a rubbing plate method includes: rubbing the target image on the target printing plate for at least a fifth preset time by a rubbing plate method based on the ink of the intaglio print, and obtaining an intaglio print of the printed target image after the target printed product presents a delicate and rich layered target image. The intaglio print uses an appropriate amount of ink, and uses a method of gradually applying pressure in different areas and lightly rubbing the plate to print the target image.

[0061] In the embodiment of the present invention, soft fine brushes of different lengths can be used to apply ink in stages with different shades of ink for target images on the solidified photosensitive resin 241 of different thicknesses, so that target image areas at different thicknesses on the gravure printmaking plate are colored with inks of different colors. That is, each time a specific color of ink based on different thicknesses on the solidified photosensitive resin 241 is applied, and pressure is gradually applied and the plate is gently rubbed in each area, and then other specific colors of ink are printed in other areas corresponding to the target image, until all colors and all areas are printed.
