Pad Printing

Pad Printing

Pad printing is an indirect printing process (gravure printing principle), which has become the most important process for printing plastic bodies & components and is especially used in the advertising material industry. KSI uses this method to print corporate logos on coated surfaces, for example.

The printing plate carries in its surface to be printed, lower-lying print image. The squeegee presses the ink into the lower printed image and cleans the excess paint cleanly. Simultaneously with the squeegee process, a tampon made of silicone rubber moves from the print material to the mold. The tampon is lowered over the cliché and thus takes over the printed image. The pad printing is therefore an indirect printing process.

Then the pad lifts off and moves to the workpiece to be printed. There, the tampon lowers and adapts to the shape. The advantage of this pressure transmission is the deformability of the tampon, by which the printing of curved surfaces (convex, concave or irregular) is possible. Due to its elasticity, the tampon adopts the shape of the body to be printed and can thus ideally transfer the motif to the workpiece to be printed. The print image is transferred to the print body. The ink transfer to the workpiece is approximately 100%.

The size of the pad printing depends here on the size of the pot, currently can print images up to a diameter of max. 130 mm to be printed. However, this varies greatly according to the shape of the printed image.

Different colors are possible, in RAL, HKS and Pantone.
