Abstract: The present invention pertains to the field of ink-jet printers used for color printing of large format articles This invention is used for improving quality and for increasing the yield of printers and comprises successively applying primary colors, suppressing color aberrations when printing a semi-transparent material on both sides, precisely positioning the head when printing an image on the substrate and eliminating the lines connecting the carriage to the systems supplying control signals, air and inks. To this end, the carriage with the jet heads is moved in one direction along a closed guiding rail which is fitted with a hatched ruler for precise positioning, wherein the heads will thus bypass the substrate on both sides while information is transmitted from the device control unit to the carriage using a radio transceiver. The printer can further be equipped with two independent and parallel substrate feeding systems for performing a one-sided printing on two substrates at the same time.
