[0038] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0040] Figure 1 The implementation flow chart of the method for printing hollow graphics provided by the embodiment of the present invention is detailed as follows:

[0041] Step S101 , performing hollow development and pattern development on a blank film plate to obtain a pattern hollow film plate.

[0042] In this embodiment, the hollow developed pattern and the graphic developed pattern are both developed on the same film plate, so that hollow printing and graphic printing of the target green ceramic sheet can be achieved through one subsequent printing.

[0043] Step S102: evenly coating photosensitive adhesive on the screen.

[0044] Step S103 , placing the patterned hollow film plate on the screen for exposure, so that the photosensitive resin in the exposed area of ​​the screen is cured.

[0045] In this embodiment, the exposed photosensitive resin will solidify, while the photosensitive resin blocked by the hollow developing pattern and the graphic developing pattern on the graphic hollow film plate will not change, thereby forming patterns corresponding to the hollow developing pattern and the graphic developing pattern respectively on the screen.

[0046] Step S104: cleaning the exposed screen to obtain a printing screen.

[0047] In this embodiment, the blocked photosensitive resin will not change. By cleaning the exposed screen, the uncured photosensitive resin can be washed away, while the cured photosensitive resin will continue to remain on the screen, thereby forming a printing screen.

[0048] Step S105 , placing printing paste on the printing screen and confining the printing paste in the through groove at the bottom of the printing scraper.

[0049] Step S106 , printing the target green ceramic sheet placed under the printing screen by using a printing scraper.

[0050] In this embodiment, the printing paste is stored in the through groove of the printing scraper, so that when performing hollow printing, there can be sufficient printing paste to ensure that the printing paste can fill the corresponding position on the target raw porcelain sheet, thereby improving the printing quality of the target raw porcelain sheet.

[0051] The embodiment of the present invention performs hollow development and graphic development on a blank film plate to obtain a graphic hollow film plate, and can simultaneously develop a hollow development pattern and a graphic development pattern on the film plate; uniformly coats photosensitive adhesive on the screen, places the graphic hollow film plate on the screen for exposure, solidifies the photosensitive adhesive in the exposed area of ​​the screen, and cleans the exposed screen to obtain a printing screen, and can expose a pattern corresponding to the hollow development pattern and the graphic development pattern on the screen, facilitating subsequent simultaneous hollow printing and graphic printing; places printing paste on the printing screen, and confines the printing paste in the through groove at the bottom of the printing scraper to store enough printing paste, ensuring that the corresponding position of the target raw porcelain piece can be filled during hollow printing, thereby smoothly carrying out subsequent hollow printing and graphic printing, and ensuring the quality of hollow printing and graphic printing; uses the printing scraper to print the target raw porcelain piece placed under the printing screen, and can achieve hollow printing and graphic printing of the target raw porcelain piece in one printing, thereby improving the printing efficiency of the target raw porcelain piece and ensuring the production efficiency of the target raw porcelain piece.

[0052] In one possible implementation, step S101 performs hollow development and pattern development on a blank film plate to obtain a pattern hollow film plate, which can be detailed as: simultaneously performing hollow development at a hollow preset position of the blank film plate, and performing pattern development at a pattern preset position to obtain a pattern hollow film plate; the hollow preset position and the pattern preset position are at different positions on the blank film plate.

[0053] In this embodiment, hollow development and graphic development are performed on a blank film plate at the same time, ensuring that the hollow development pattern and the graphic development pattern can be set on the same film plate, ensuring that only one film plate can be used to complete the hollow printing and graphic printing of the target green ceramic sheet in the future.

[0054] In one possible implementation, step S106 prints the target green ceramic sheet placed under the printing screen by using a printing scraper, specifically: determining a printing direction; moving the printing scraper along the printing direction on the printing screen so that the printing paste passes through the uncured area on the screen and is coated on the target green ceramic sheet.

[0055] In this embodiment, a printing direction is determined, and the printing scraper is moved along the printing direction on the printing screen, so that the printing paste in the through groove can pass through the uncured area on the printing screen and contact the target raw porcelain piece. By moving the printing scraper, the bottom of the printing scraper can scrape off the excess printing paste on the target raw porcelain piece and store it in the through groove; when the hollow printing position is reached, the paste stored in the through groove can fill the position corresponding to the target raw porcelain piece, ensuring the quality and speed of hollow printing, thereby improving printing efficiency.

[0056] Preferably, before printing the target green ceramic sheet placed under the printing screen by the printing scraper in step S106, the method may further include: placing the printing scraper and the printing screen vertically.

[0057] In this embodiment, the printing scraper and the printing screen are placed vertically, which can ensure that the printing scraper can move smoothly so that the printing paste can be evenly coated on the target green ceramic sheet.

[0058] It should be noted that placing the printing scraper and the printing screen vertically is only a preferred method. The printing scraper can also be placed at an angle according to the needs during use.

[0059] The embodiment of the present invention performs hollow development and pattern development on a blank film plate to obtain a pattern hollow film plate, and can simultaneously develop a hollow development pattern and a pattern development pattern on the film plate, ensuring that only one film plate can be used to complete hollow printing and pattern printing of a target green ceramic sheet in the future; uniformly coating a photosensitive adhesive on a screen plate, placing the pattern hollow film plate on the screen plate for exposure, solidifying the photosensitive adhesive in the exposed area of ​​the screen plate, and cleaning the exposed screen plate to obtain a printing screen plate, and can expose a pattern corresponding to the hollow development pattern and the pattern development pattern on the screen plate, facilitating the subsequent simultaneous hollow printing and pattern printing; placing printing paste on the printing screen plate, and confining the printing paste in the through groove at the bottom of the printing scraper so as to store enough The printing paste is used to ensure that the corresponding position of the target raw porcelain piece can be filled during hollow printing, so that the subsequent hollow printing and graphic printing can be carried out smoothly, and the quality of hollow printing and graphic printing can be guaranteed; the target raw porcelain piece placed under the printing screen is printed by a printing scraper, and the printing scraper is moved along the printing direction. The bottom of the printing scraper can scrape off the excess printing paste on the target raw porcelain piece and store it in the through groove; when the hollow printing position is reached, the paste stored in the through groove can fill the corresponding position of the target raw porcelain piece, ensuring the quality and speed of hollow printing, improving printing efficiency, and being able to achieve hollow printing and graphic printing of the target raw porcelain piece in one printing, thereby improving the printing efficiency of the target raw porcelain piece and ensuring the production efficiency of the target raw porcelain piece.
