This tool is a device, either physical or software-based, used to determine the optimal duration required to expose a screen printing stencil to a light source. It facilitates accurate replication of the desired image onto the screen. For example, one may input information such as mesh count, emulsion type, and light source intensity into the instrument. The device then processes this data to generate a suggested exposure time.
Precision in stencil creation is paramount to high-quality prints. Over or underexposure can lead to image degradation, loss of fine details, or stencil breakdown during the printing process. Utilizing such a tool mitigates these risks, saves resources by reducing wasted materials, and enhances workflow efficiency. Historically, printers relied on trial-and-error methods, which were time-consuming and often yielded inconsistent results. The advent of these calculators represents a significant advancement, providing a scientific, repeatable approach.
