Embodiment Construction

[0011] The following examples illustrate the present invention further.

[0012] The printing process in the present embodiment comprises the following steps in turn:

[0013] (1) Printing the UV-curable printing ink onto the substrate through the printing device;

[0014] (2) Utilize the ultraviolet rays that the first group of ultraviolet curing lamps emit to irradiate the printing layer of the ultraviolet curing printing ink to make the printing layer of the ultraviolet curing printing ink cross-linking reaction; the first group of ultraviolet curing lamps used in this step is an ultraviolet curing The power of the lamp is 8000-10000 watts (it can be divided into three levels of 8000 watts, 8600 watts and 10000 watts, one of which can be selected during printing); the irradiation time is 1-2 seconds. The first group of ultraviolet curing lamps is arranged in the first oven, the bottom of the first oven is open, the substrate passes under the opening at the bottom of the fi...

Abstract

A printing process, comprising the following steps in turn: (1) printing an ultraviolet-curable printing ink on a substrate by a printing device; (2) irradiating a printed layer of the ultraviolet-curable printing ink with ultraviolet rays emitted by a first group of ultraviolet curing lamps, The UV-curable printing ink printing layer is made to undergo cross-linking reaction; (3) the UV-curable printing ink printing layer is irradiated with ultraviolet rays emitted by the second set of UV curing lamps, so that the UV-curing printing ink printing layer is cured and dried to complete the printing. The invention can make the printing surface of the obtained printed matter smooth, the hand feeling is fine, the smoothness is close to that of silk, and has better visual effect and hand feeling, and is more suitable for the outer packaging of high-end products.

Description

technical field [0001] The invention relates to a printing process. Background technique [0002] At present, when printing with ultraviolet curable ink, the usual method is to first print the ultraviolet curable printing ink on the substrate through the printing device, and then use the ultraviolet rays emitted by the ultraviolet curing lamp to irradiate the printed layer of the ultraviolet curable printing ink. The printing layer of the UV-curable printing ink is cured and dried to complete the printing. The printed matter obtained by the above-mentioned process has a relatively rough printing layer of the ultraviolet curable printing ink, and the visual effect and hand feel are not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a printing process that can make the printing layer of the ultraviolet curable printing ink of the printed matter smooth and delicate. The technical scheme adopted is as follow...
