Wenzhou Wenxin Printing Technology Co., Ltd.  produces and operates automatic high-end equipment such as hot foil stamping machine, paper embossing machine, screen printing machine, aluminum laminated cardboard (primer coating) machine, register sheet cutter machine, laser embossing machines, etc. It is also an agent for the distribution of digital printing machines and offset printing machines such as Heidelberg, Komori, Roland, Kodak and Hewlett-Packard. The company provides excellent, professional pre-sales and after-sales teams to ensure that users receive professional and efficient team services, and to provide a variety of printing processes on innovation and technical training. With a number of doctoral and master's degree students to provide the team with strong technical support and innovation guarantee.

Then,screen printing machines are devices used to apply ink or other materials onto various surfaces, such as textiles, paper, plastics, and more. The machine uses a screen or a mesh stencil to transfer the ink onto the surface. The screen printing process involves the use of a mesh screen that is stretched over a frame. The design or pattern to be printed is then exposed onto the screen using a light-sensitive emulsion.Once the screen is exposed, the areas that are not part of the design are washed away, leaving behind the stencil. The stencil is then placed onto the surface to be printed, and ink is applied onto the stencil. A squeegee is then used to push the ink through the open areas of the stencil onto the surface below, creating the printed design.Screen printing machines come in various sizes and types, from manual hand-operated machines to fully automatic machines that can produce thousands of prints per hour. They are widely used in the textile industry for printing designs onto t-shirts, sweatshirts, and other clothing items, as well as for printing posters, decals, and other promotional items.

Meanwhile,Screen printing, also known as silk screening, is a printing technique that involves the use of a mesh stencil (called a screen) to transfer ink onto a substrate. Screen printing machines are designed to automate this process, making it more efficient and accurate.

The working principle of screen printing machines involves several steps:Preparation of the stencil: The first step in screen printing is to create the stencil or screen. This is typically done by coating a mesh screen with a light-sensitive emulsion and then exposing it to a film positive image of the design. The exposed emulsion is then washed out, leaving a stencil of the design on the screen.Setup of the machine: Once the stencil is ready, it is mounted onto the screen printing machine. The machine consists of a flat table or platen where the substrate to be printed is placed, and a screen carriage that holds the screen in place.Ink preparation: The ink is prepared by mixing the desired color with a solvent or medium to achieve the desired consistency and viscosity.Printing process: The substrate is placed onto the table, and the screen carriage is lowered onto the substrate. The ink is then poured onto the screen, and a squeegee is used to push the ink through the open areas of the stencil and onto the substrate. The screen is then lifted, and the substrate is removed from the machine.Drying and curing: The printed substrate is then dried and cured to set the ink and ensure that it adheres to the substrate properly.Cleanup: Once the printing process is complete, the screen is cleaned thoroughly to remove any ink residue and prepare it for the next print run.

Overall, screen printing machines automate the process of transferring ink onto a substrate using a mesh stencil. By doing so, they increase the speed, accuracy, and consistency of the printing process, making it an ideal choice for producing high-quality prints in large quantities.
