Flexographic printing and machines help the user to print on any type of substrate, including metallic films, plastic, cellophane, and paper. Previously similar to the old letterpress printing techniques, flexographic printing is a form of printing process which utilizes a flexible relief plate. Some applications for flexography are milk cartons, disposable cups,
paper/plastic bags, and sweet wrappers. Flexography printing may also be used for envelopes, labels, and newspapers. Other printing procedures and machines include foil printing, print screening, pad printing, custom label printing, flexo presses, digital printing and label printers.
