Membrane switch proofing is the process of bridging between pre-press production and printing, allowing users to anticipate the final membrane switch effect before mass production. It can provide a standard for the whole membrane switch production process and provide a strong guarantee for the improvement of membrane switch quality. Two ways of membrane switch proofing.
Soft proofing is realized on the color monitor, which is undoubtedly the most convenient, fastest and cheapest proofing method, requiring the color monitor to be highly accurate and must be properly calibrated. The obvious shortcomings of the soft proofing method are: low resolution, only 72 dpi; color accuracy depends on the performance of the monitor and calibration, metallic colors can not be accurately reflected; can not provide reference for the membrane switch production process later.
It is necessary to output the film and make the screen plate, and then finish the proofing on the screen printing machine. The production process of traditional proofing sample version and mass production version is the same. The same file data is used for proofing and mass production. Through proofing, potential problems such as tortoise pattern, color and font pattern can be found. The technical content of membrane switch sample making is high, and professional technicians are needed to make accurate and perfect samples, which are labor-intensive, involve many processes, and cost more, and the sample making period is also longer.
