Improvements introduced in wetting systems for offset printing and a mechanism for their application

摘要

The improvements consist in supplying the wetting system with a water based solution including a determined additive. This solution is subjected, through a mechanism forming a part of this invention, to a process of agitation by which it absorbs 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. <IMAGE>
