The freely-programmable PX Ink Jet Printer is intended for industrial applications. The printer's mode of operation is based on the Continuous Ink Jet (CIJ) principle. Possible uses range from the simplest applications, like printing the date, to complex applications in which the printer can be integrated in a system of machines via a network connection. The optimized print head can be installed in any position and produces a 1 to 4-line printed image in consistently good quality – even on uneven or structured surfaces. The use of a wide range of different inks enables the marking of extremely diverse materials like films, glass, metal, plastic, paper etc. virtually regardless of the environment. The choice ranges from different standard inks to special inks that are colorfast, heat resistant and can be read with UV. Example uses are MHD, lot numbers, logos, barcodes, consecutive numbering, production data like the date, time etc.
