Method for printing transparent ink on different printing media

Abstract

A method for printing transparent ink on different printing media is provided. In a one-time printing process, printing with the transparent ink is performed for a plurality of times on a printed product, and a curing process by means of UV light irradiation is then performed once. The method is characterized in that, after performing the printing with the transparent ink for the first time, the curing process by means of UV light irradiation is performed once.

Claims

1. A method for printing transparent ink on different printing media, the method comprising: in a one-time printing process, printing a same printing position of a printed product being performed a plurality of times; and performing a curing process by means of UV light irradiation after said one-time printing process is completed, wherein the curing process by means of UV light irradiation is merely performed after a printing of the transparent ink is performed for the first time and the final time of the plurality of times of printing.

Description

DETAILED DESCRIPTION OF THE INVENTION

(1) A method for printing transparent ink on different printing media according to a preferred embodiment of the present invention is described below.

(2) In the method for, printing transparent ink on different printing media, in a one-time printing process, after performing printing with the transparent ink for a plurality of times on a printed product, a curing process by means of UV light irradiation is performed once.

(3) When performing the printing with the transparent ink for the first time, after a base process is completed, a UV light is turned on to perform a curing process by means of UV light irradiation once on the transparent ink having undergone the base process. As such, the transparent ink having undergone the base process is irradiated and immediately cured, so as to prevent deformation of the transparent ink. After performing the printing with the transparent ink for the 2.sup.nd to the N.sup.th times, a final curing process by means of UV light irradiation is then performed. It should be noted that, the curing process by means of UV light irradiation may also be performed once after the printing with the transparent ink each time, in a way that the transparent ink of the previous time has already cured before the lamination of the transparent ink is stacked each time on the transparent ink of the previous time.

(4) With the above design, the curing process by means of UV light irradiation is activated after the printing of the transparent ink is performed for the first time or even after the printing of the transparent ink is performed each time. Thus, even after several times of printing and stacking, the transparent ink does not incur the issue of gathering or spreading due to the surface tension, so as to provide printing quality that is significantly different from that of the prior art.

(5) In conclusion, based on the disclosure of the application, the method for printing transparent ink on different printing media provided by the present invention indeed meet its anticipated object, and is industrially applicable.

(6) While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures derived based on the disclosure or teaching of the application, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
