What is the Pad Printing and where is used.
Pad printing is an indirect printing process that allows you to easily, with high fidelity and resolution, draw, write, and decorate both on flat surfaces and on concave, convex or otherwise irregular surfaces.
It is a printing technique that "allows you to transfer 2D images and graphics on 3D objects and surfaces".
Pad Printing allows you to print with a higher definition than silk-screen printing.
By using a soft and flexible pad (usually silicone), an indelible ink film is transferred from a steel or photopolymer-coated plate (pad cliché) to the substrate surface.
The printing surface may be non-planar thanks to the soft print pad that can easily be adapted to the different shapes on which it is pressed.
Pad Printing allows you to print with a higher definition than silk-screen printing, enabling the reproduction of slimmer streaks with sharpness, even in multiple colors, and printing "wet on wet".
In fact, it is possible to obtain excellent prints even in quadricromia, using clicks on the clusters (especially those in photopolymer), similar to those used for lithography.
This printing process can also be used to deposit functional materials such as conductive inks, adhesives, lubricants.
