Printed pins have colorful designs printed on their entire surface. There are two kinds of printing processes used in producing printed lapel pins according to different designs. One is called silk screen printing and another is called offset printing. Silk screen is generally used to print the simple designs with solid colors like company logos; Offset printing is used to print the designs with complex structures and gradational patterns like real photos. There will be an epoxy dome added on the printed side of the lapel pin, to provide protection for the printing.
