Long term since, there must be a printing plate printing, the printing ink (or color) only under pressure, can be transferred to the substrate. Therefore, the evolution of people think of printing technology development is a printing plate and pressure. However, in recent decades, especially in the last ten years, due to the application of electronics, laser, computer technology continued to expand printing field and high-tech achievements in printing, a challenge to the traditional analog printing to printing plate and pressure based, emerge in an endless stream of digital printing method does not need a printing plate and pressure. For example: laser printing, electron beam imaging, ink-jet printing, thermal transfer, sublimation transfer, liquid thermal inkjet printing etc.. The printing of the definition of a new concept.
