Rivet binding is also used in our printing jobs. For example, a mood barometer consists of two stamped, round discs made of 350g/m2 glossy offset paper. The offset paper is printed with CMYK colors on both sides and processed with printing varnish. The stamping contour is a circle for the outer dimension, plus two cutouts. Small round cutouts in the middle of the discs are needed for the rivet which connects both different discs to one mood barometer.
