Introduction:

The GWF Aqueous Coater is built for performance, reliability and precise lay down of high quality spot or flood aqueous coating. It is designed for installation between the last print unit and the press dryer. Aqueous coatings is water base coating scuff-resistant and used to protect print mailed pieces as they go through the mail, it provides better rub protection than varnish and dries quickly. In addition, It is used to provide a high-gloss or matte surface that deters dirt and fingerprints and enhance the look of brochures, catalog covers and direct mail pieces.


Application:

The GWF 38” Aqueous Coater incorporates three cylinders design and a motorized pan roller semi-submerged in a coating fountain pan. The coating flow into the pan via a closed loop circulation pump,  as the pan roller comes in contact with the transfer anilox roll, a thick layer of  viscous coating is deposited on the roll.

 A doctor blade is used to scrape the excess coating from the surface leaving just the measured amount of coating in the cells. A Flexo plate mounted on the plate cylinder, receives the coating from the cells and transfer it to the printed paper.

It is important to note that the characteristics of an anilox roll determine the amount of coating that will be transferred to the plate. Although, there are  few times where  smooth transfer cylinder along with the metering roll were used and the lay down quality was equally good.
