Disclosed herein are aqueous fountain solutions used in defining an image on a printing plate. The solution comprising a source of a volatile carbonyl compound, an aqueous compound, a water soluble polymer, a pH modifier, a surfactant and a reactive composition capable of reacting with the volatile organic carbonyl compound to substantially reduce the release thereof. Also disclosed are a printing process using the same fountain solution and an overcoat solution to be used as a finish coating in a printed structure.
On dévoile des solutions de mouillage aqueuses destinées à être employées pour la définition d'une image sur une planche d'impression. La solution renferme une source d'un composé carbonylé volatil, un composé aqueux, un polymère hydrosoluble, un régulateur de pH, un agent de surface et une formulation réactive pouvant réagir avec le carbonyle volatil afin de réduire de manière substantielle les rejets de ce composé. On dévoile également un procédé d'impression faisant appel à une solution de mouillage et à une solution de finition employée pour la finition d'une structure imprimée.
