boasts that its new Logica Cartesio can “pad print the impossible.” It describes the unit as a “numeri- cally controlled pad printing centre for high quality multi-colour printing on sophisticated 3D objects.” All the pads are arranged radially on a drum.
The initial position of the pads is not important, as the machine software makes it possible to freely position the pads on different clichés and on the object. Similarly, engraving of the graphic on the cliché is very flexible. Logica Cartesio is available in three different sizes, in relation to the number of colours, the size of the piece and the number of colours to be printed. It comes equipped
with an interchangeable plate for cliché support, making it possible to freely mix large and small clichés and ink cups. Each spoke can accept different shapes and sizes of pad. Output depends on the number of prints on the
Pad printing advances

Despite all the noise about in-mould decoration and labelling, downstream printing using technolo- gies such as pad printing is still dominant. And pad printing continues to develop. At Plast in May, Italian equipment supplier Comec said the demands of its leading customers are heading essentially in two directions: expanding the possibilities of customising objects, with more colours, maybe different graphics in different points of the same object; and speed and simplic- ity of printing – for example having only one machine to carry out the whole process of decorat- ing a group of objects. Comec says its new XE TECH 16-20 pad printing machine meets both requirements. Comec describes this fully automated system as capable of self-learning the ink pick-up and print points. “In addition, you can make the best suited choice to the work to be carried out between three different pads and six clichés (with hermetic ink cups and ceramic rings).” The on-board computer can store hundreds of programs, which in turn can contain up to 50 printing stages each. The structure encloses one pad printing head movement group on X and Y axes with brushless motors; a second movement group on Z axis, again with brushless motor and magnetic coupling pad; three pads with quick-coupling devices; a motor- ised pieces holder; and a programmable pad cleaning device. The machine is also equipped with Comec’s Hot Wind 200 hot air blower with adjustable tubes to direct the jet of air wherever it is needed; and a vacuum device for holding the piece being printed.

object. Typically, it can range from 150 pieces/hour for 15-20 prints around the object, up to 500 pieces/hour for more simple decoration lay outs.
