Benefits of technology

Enables precise and efficient application of medium to high viscosity products onto specific zones of substrates, allowing for customization and secure document preparation by applying layers before or after printing, with improved precision and control over traditional spreading methods.

Problems solved by technology

These systems are however limited to inks or products with a controlled fluidity and a low viscosity as well as molecules of very small dimension.
For example, it is not possible with the existing appliances to apply, without contact with the medium, products such as varnish, scratchable ink, conducting ink or glue, in particular onto a plastic substrate or the plastic face of a substrate.

Embodiment Construction

[0032]Let us first consider FIG. 1. The machine is controlled by a control computer (10) which controls the different work stations, and also which collects the information from the different sensors. For example, the sensors give information on the positions of the substrates (13), on the configuration data of the substrates (13) or on the validation information following an operation, effected correctly or not. The substrates (13) awaiting printing are placed in an input magazine (5) with a capacity specified according to the nature of the substrate (13) and of the printing needs. In one implementation example, the input magazine (5) is designed to accept several thousand substrates (13) of variable nature, of variable thickness up to 800 μm and of variable dimensions (credit-card format up to format AO) and possibly of which at least one face is in plastic. Once the application process has ended, the substrates (13) are stored in an output magazine (8) with generally the same cap...

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.

Description

RELATED APPLICATIONS[0001]The present application is a reissue of U.S. patent application Ser. No. 11 / 423,761, filed Jun. 13, 2006, the disclosure of which is hereby incorporated by reference herein in its entirety.RELATED APPLICATIONS [0002]The present application is based on, and claims priority from, FR Application Number 0505981, filed Jun. 14, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety.BRIEF SUMMARY OF THE INVENTION[0003]The invention concerns the area of printing without physical contact onto a substrate of which at least one face is in plastic, and more particularly a machine, independent from a printing system, which allows, before or after the printing system, the application by jet of a product having a viscosity going up to 1000 centipoises, and described as average to large, such as varnish, glue, conducting or scratchable ink, onto a substrate of variable thickness and dimensions.[0004]There already exist jet printing system...
