Five-color printing sticky printing solution

My company has commissioned the factory of the outsourcing association to print a batch of four-color, two-sided, five-color printed jobs for us because we need to emboss the black text on the silver ground. Therefore, the arrangement of the color sequence is to print the silver ink (front and back) first, and then Four-ink printing ink. Since the amount of ink on the reverse four-color printing is small, after printing the silver pattern on the front and back sides, the four-color printing on the reverse side is performed first, and the front side pattern with a larger amount of ink is printed after drying for several hours. However, when the front side pattern is printed, the phenomenon of black ink embossed on the solid silver surface sticks off the silver ink (commonly called viscous imprinting).

The outsourcing factory took a variety of treatments and eventually failed to solve the problem. Considering that the outsourced factories have insufficient experience in five-color printing, and the customer requires a more urgent delivery date, and the printed matter does not have enough time to air dry, we have purchased an imported imprinting roller adhesive, commonly known as the back gun. Ointment, give it to the outside association factory to try. The printing press operator of the outside association factory evenly applied this aftertaste to the impression cylinder, which solved the problem of sticking and embossing.

After several trials, it was found that after the special paper printing or the five-color double-sided printing and the like are prone to stick and imprint, the use of the post-gun paste can easily solve the problem.
