Makes it possible to easily carry out printing on curved surfaces (convex or concave)
Tampon printing is an indirect method of printing which has been developed into one of the most important processes for printing onto polymer pieces.
Printing process:
First of all, a print block is prepared. This carries on its surface the printed image which is deeply embedded. A blade squeezes the ink into the deep indentations of the image and then sweeps the excess ink off the block. After this process, an elastic tampon printer comes into operation. This lands on top of the print block and becomes impregnated with the ink lying in the indentations of the image, which it then transfers to the plastic part (indirect printing process).
The advantage of this process consists, above all, in the ability of the tampon, which is made from silicon cautschuk (India rubber), to alter its shape. The tampon is made from material which is very elastic, so that it can adapt to almost any surface formation, and therefor makes it possible to easily carry out printing on curved surfaces (convex or concave). Also the tampon printer cleans itself after every operation, and can therefor be used many times over.
Single or multicoloured printing machines, manufactured by Teca-Print, are used by CREAVAC for tampon printing. The technical details of these machines are outlined as follows:
