ABSTRACT:
A wetting system is supplied with a water based solution including a determined additive. This solution is subjected, through a mechanism, to a process of agitation by which it adsorbs a high oxygen content. As a result of these improvements, the solution which wets the aluminium plate, from which the printing is done, acquires a high free oxygen content, increasing the water-ink interface and improving the quality of the printing.
