At a time when the advertising industry is booming, digital advertising photo machines have become an indispensable device in the production of advertising images with their excellent printing effects. Among them, high-precision print heads play a core role in helping advertising images achieve accurate reproduction and delicate presentation of colors.The high-precision print heads of digital advertising photo machines use advanced piezoelectric technology. The piezoelectric print head contains many tiny piezoelectric ceramics. When voltage is applied, the piezoelectric ceramics will deform slightly at high speed. This deformation can accurately control the ejection of ink in the nozzle, so that the ink droplets are ejected from the nozzle with a very small volume and uniform speed. Compared with traditional thermal foaming print heads, piezoelectric print heads do not need to heat the ink, avoiding chemical changes in the ink due to heat, thereby ensuring the stability of the ink. Stable ink performance is the basis for achieving accurate color reproduction, because any change in the ink composition may cause deviations in the printed color.High-precision print heads have extremely high resolution. Resolution refers to the number of ink dots per inch. The higher the resolution of the print head, the more ink dots can be sprayed per unit area, and the richer the details of the picture. High-precision print heads achieve dense and uniform nozzle distribution by optimizing the arrangement and design of nozzles. During the printing process, these nozzles can accurately spray ink on paper or other media according to the preset program to form a delicate image. Whether it is the facial expression of a person, the texture details of a product, or the light and shadow changes in the advertising background, they can all be presented clearly and realistically with the support of high-precision print heads.In order to achieve accurate color reproduction, high-precision print heads usually support multi-color printing. Common digital advertising photo machine print heads use a six-color or even more color ink system. In addition to the basic cyan, magenta, yellow and black, auxiliary colors such as light cyan and light magenta are also added. These rich color combinations can cover a wider color gamut, making the printed advertising images more vivid and full. During the printing process, the print head can accurately control the amount and position of each color ink according to the color information of the image, thereby achieving accurate color mixing. For example, when printing a colorful landscape advertising picture, the high-precision print head can accurately restore the blue sky, the green grass and the brilliant colors of the flowers, making the audience feel as if they are there.The high-precision print head also has excellent ink drop control capabilities. The size of the ink drop directly affects the delicateness and color level of the printed picture. The high-precision print head can accurately control the size of the ink drop according to different printing needs. When printing delicate parts, the print head will spray extremely small ink droplets to make the picture smoother and more natural; when printing parts that need to highlight the contrast, the print head can appropriately increase the size of the ink droplets to enhance the color saturation and contrast. This flexible ink drop control capability makes the advertising picture more outstanding in color transition and level performance, avoiding the phenomenon of color fault or mottled.In addition, the high-precision print head of the digital advertising photo machine is combined with advanced image processing technology to further improve the printing quality of the advertising picture. Image processing technology can optimize and process the original image, remove noise and defects in the image, and adjust the color balance and contrast of the image to make it more in line with printing requirements. The print head accurately prints according to the processed image data, ensuring that the final output advertising image is highly consistent with the original design.The high-precision print head of the digital advertising photo machine achieves accurate reproduction and delicate presentation of the color of the advertising image through advanced piezoelectric technology, high-resolution design, multi-color printing system, excellent ink drop control ability and perfect combination with image processing technology. It brings higher quality and more creative possibilities to the advertising industry, becoming an indispensable tool in advertising production.
