1. Wet press dry method, that is, wait for the printing ink on the tinplate print to dry, and then glaze on the tinplate surface. This glazing method does not cause problems such as ink penetration and fading, but since a glazing process needs to be passed through after printing, it is not conducive to improving production efficiency and increasing production costs.
2. Wet press wet method, that is, glazing is performed on the surface of the tinplate before the printing ink of the tinplate prints is dried, which shortens the time between printing and glazing processes, saves energy and production time, and reduces consumption. However, since the printing of the latter color is followed by glazing on the wet ink, it is easy for the pigment of the latter color to penetrate into the glazing oil, causing the color of the printed graphic ink to lose color, and the gloss of the printed matter is not enough. , The appearance quality is seriously degraded.https://www.fhpails.com/
