Embodiment Construction

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

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

[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 first ...

Abstract

The invention discloses a printing technology which comprises the following steps: (1) printing a printed material with ultraviolet curing printing ink by a printing device; (2) irradiating an ultraviolet curing printing ink printed layer by ultraviolet rays emitted by a first group of ultraviolet curing lamps to generate crosslinking reaction on the ultraviolet curing printing ink printed layer; (3) irradiating the ultraviolet curing printing ink printed layer by ultraviolet rays emitted by a second group of ultraviolet curing lamps to cure and dry the ultraviolet curing printing ink printed layer to finish printing. According to the printing technology, the printed surface of an obtained printed product is smooth, and the handfeel is fine and close to the slide sensitivity of a silk; therefore, the printed product is better in vision effect and handfeel and is more suitable for outer packaging of top-grade products.

Description

technical field [0001] The invention relates to a printing technology, in particular to a printing technology capable of making the printed layer of the ultraviolet curable printing ink of the printed matter smooth and delicate. It belongs to the field of printing technology. Background technique [0002] At present, when using ultraviolet curable ink for printing, 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 using the above-mentioned technology has a relatively rough printing layer of the ultraviolet curable printing ink, and the visual effect and feel are not good. Therefore, the printing industry is looking forward to the emergence ...
