Abstract
The invention concerns a contactless numerical printing machine for products of average fluidity, such as varnish, glue, and conducting or scratchable ink, onto a substrate of variable thickness and dimensions. The machine includes a special device for printing without contact by projection. The projected materials are materials of average fluidity or composed of large-dimension molecules. The process used includes an electro-acoustic device for control of the projection, and a multiplicity of projection nozzles, each controlled individually.The machine also includes a production chain with different work stations, whose printing devices are controlled by a computer management system. The production chain allows printing with a certain precision in given zones located during the processing by an appropriate work station.
