丝印网版晒版流程
Screen printing mesh is an essential tool in the process of screen printing. It plays a crucial role in transferring the ink onto the printing substrate to create the desired design. However, before this can happen, the screen printing mesh needs to go through a process called mesh exposure or screen exposure, also known as 晒版. This process involves exposing the mesh to a UV light source to harden the emulsion and create the stencil for the printing.
在丝网印刷流程中，晒版是一个非常重要的步骤。通过这个步骤，可以将图案转移到印刷基材上，从而实现设计的目的。然而，在将油墨转移到印刷基材之前，丝网印刷网版需要经过一系列处理，其中包括网版曝光。这个过程会将网版暴露在紫外光源下，从而硬化乳胶并形成印刷的模板。
The first step in the screen exposure process is to prepare the artwork or design that will be transferred onto the mesh. This design is usually printed on a transparent film or created digitally, depending on the complexity of the design. The transparency of the film is crucial as it allows the UV light to pass through and create a clear stencil on the mesh.
在晒版流程中的第一步是准备要转移到网版上的图案或设计。这个设计通常会印在透明薄膜上，或者根据设计的复杂程度进行数字化处理。薄膜的透明度至关重要，因为它可以让紫外光穿透，并在网版上形成清晰的模板。
Once the design is ready, the next step is to coat the screen printing mesh with a light-sensitive emulsion. This emulsion is usually applied to both sides of the mesh using a scoop coater to ensure even coverage. After coating, the mesh is left to dry in a dark room to prevent premature exposure to light.
一旦设计准备好，下一步是用感光乳胶涂抹丝网印刷网版。通常会使用刮涂器将这种乳胶涂抹在丝网的两侧，以确保覆盖均匀。涂抹完毕后，将网版放在黑暗的房间中晾干，以防止过早暴露在光下。
After the emulsion has dried, the next step is to place the transparent film with the design on top of the coated mesh. This is done in a special exposure unit that emits UV light to transfer the design onto the emulsion. The exposure time may vary depending on the complexity of the design and the type of emulsion used.
在乳胶干燥后，下一步是将带有设计的透明膜放在涂抹的网版上方。这一步骤通常在专门的曝光设备中进行，该设备会发出紫外光以将设计转移到乳胶上。曝光时间可能会因设计的复杂程度和所使用的乳胶而有所不同。
Once the exposure is complete, the mesh is then washed with water to remove the unexposed emulsion and reveal the stencil. This process requires careful handling to ensure that the stencil is not damaged during the washing process. After washing, the mesh is dried and can be used for screen printing.
当曝光完成后，网版会被用水冲洗，以去除未暴露在光下的乳胶，并显示出模板。这个过程需要仔细处理，以确保在清洗过程中不损坏模板。冲洗后，网版会被晾干，并可以用于丝网印刷。
xposedIn conclusion, the screen exposure process is a critical step in screen printing that requires attention to detail and careful handling. From preparing the design to coating the mesh with emulsion and exposing it to UV light, each step plays a crucial role in creating a successful stencil for printing. Properly executed, the 晒版 process can result in high-quality prints that
meet the desired specifications and designs. It is a combination of art and science that requires skill, precision, and creativity to achieve the desired results.
