Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] In this embodiment, the process of using the hollow backing paper for partial oiling is as follows:

[0029] Step 1) as in figure 2 As shown, a large version is formed according to the specifications of the lining paper. The box ɑ in the figure indicates the line of the lining paper, and ɑ1 indicates the layout of the carton. figure 2 The medium and large version includes the layout of 4 cartons ɑ1, ɑ2 indicates the reserved white area, and then releases the large version PDF and puts it into AI (abbreviation of Adobe Illustrator) software to be processed (easy to process).

[0030] Step 2) Determine the coordinates of the reserved white area ɑ2 on the large version:

[0031] Step 2-1) Set the starting point of the horizontal coordinate, that is, the X coordinate, at the position where the positioning line is 0, namely fi...

Abstract

The invention discloses a method for partial oiling by using hollowed-outlining paper. The method comprises the following steps that according to a reserved white area, lining paper of the inner side of rubber blanket rolled around a rubber roller is hollowed out, and then by using squeezing action between the rubber roller and an impression cylinder, gloss oil on the rubber blanket is transferred to a printing stock between the rubber roller and the impression cylinder. A traditional partial oiling method is difficult to overcome the problem of high cost, according to the method for partial oiling by using the hollowed-out lining paper, by hollowing-out the lining paper on the inner side of the rubber blanket, in the reserved white area, because pressure is reduced when the rubber blanket and the impression cylinder are in contact, the gloss oil cannot be transferred, so that partial oiling is realized, the cost of the lining paper is only about 1 yuan, therefore, the method for partial oiling by using the hollowed-out lining paper greatly reduces the cost of partial oiling, is simple and convenient to operate, and cannot delay production.

Description

technical field [0001] The invention relates to the technical field of lithographic offset printing, in particular to a local oiling method. Background technique [0002] In the printing process of packaging materials, in order to increase the brightness and surface protection of the pattern, it is often necessary to oil the ink after printing. Packaging materials such as packaging boxes need to be pasted into boxes in the post-production process, and the surface after oiling is not conducive to pasting. Therefore, in the early oiling process, it is necessary to consider the needs of the post-press process and carry out retention White, that is, local oiling. [0003] In order to facilitate the understanding of the content of the next part of this article, first introduce the lithographic offset printing process. figure 1 Schematic diagram of the principle of the lithographic offset printing process. Offset lithography is a mainstream printing process today, such as figu...
