Specialty printing, as the name suggests, refers to special types of printing methods, that is, different types of printing methods compared to ordinary printing methods. Specialty printing technology mainly studies the printing processes, printing materials, printing equipment, and printability issues in specific situations. Specific situations mainly include: special uses, special printing principles, printing methods, and special printing effects. The unique technologies of specialty printing are mainly in the following aspects:
Diverse Substrates
Specialty printing emerged because ordinary printing cannot handle certain special materials. Therefore, the most prominent advantage of specialty printing is its ability to print on various types of substrates. First, the shapes of the substrates are diverse, whether flat or three-dimensional, regular or irregular; specialty printing can handle them all. Second, the materials of the substrates are diverse, including not only paper but also sheet metal, plastic, cellophane, cardboard, wood, ceramics, glass, and metals. Third, the surface properties of the substrates are diverse, including smooth, rough, uneven, and uniform, etc. Fourth, the sizes of printing substrates are diverse, ranging from large to small formats. Specialty printing has extremely high compatibility with printing substrates, enabling it to perform many tasks that ordinary printing cannot.
