Abstract

When printing with conventional UV-curable inkjet printers, it is almost impossible to obtain high-resolution images on the uneven printing media such as molded plastic products with undulations of more 3mm. This study is related to the new digital pad printing technology; which produces high-quality images on such uneven surfaces. The process to produce images is as follows: (1) Inkjet printing is carried out on a heated silicon rubber film with UV curable ink diluted with an organic solvent. This solvent evaporates immediately after the ink droplet reaches the film surface, making the ink viscosity higher: Thus the spread of the printed ink dot stops. This results in sharp printed images. (2) A soft pad is applied to the backside of a silicon rubber film, which can be pressed against an object, thereby transferring the ink image onto the object's surface. (3) Finally the UV irradiation makes the ink hard. Through this process, we can decorate various objects with high-quality images.
