Embodiment Construction

[0017] See figure 1 and Figure 2a-2e , figure 1 is a flowchart of a method for manufacturing a magnetic printing master according to a first embodiment of the present invention, Figure 2a-2e yes figure 1 Schematic representation of the different steps of the fabrication method shown. Such as figure 1 and Figure 2a-2e As shown, the manufacturing method of the magnetic printing master in this embodiment includes the following steps.

[0018] In step 11, as in Figure 2a As shown, the first magnetic field is used to magnetize the magnetizable material layer 10 along the first magnetization direction, and then a magnetic field in the same direction as the first magnetization direction is formed in the magnetizable material layer 10 .

[0019] In step 12, as in Figure 2b As shown, a local region 101 of the magnetizable material layer 10 is heated and demagnetized by a laser beam. Specifically, the local region 101 of the magnetizable material layer 10 is heated to abov...

Abstract

The invention provides a magnetic printing mother set, a preparation method thereof and preparation equipment. The preparation method of the magnetic printing mother set includes magnetizing a magnetizable material layer along a first magnetizing direction by the aid of a first magnetic field; heating and demagnetizing local areas of the magnetizable material layer by the aid of laser beams; and magnetizing the local areas of the magnetizable material layer by a second magnetic field along a second magnetizing direction different from the first magnetizing direction. The magnetic printing mother set, the preparation method thereof and the preparation equipment have the advantages that a preset magnetized area combination can be formed on the magnetic printing mother set, and furthermore, a versatile pattern effect can be realized on the surface of a printing article.

Description

technical field [0001] The invention relates to the field of magnetic orientation printing, in particular to a magnetic printing master plate and its manufacturing method and manufacturing equipment. Background technique [0002] At present, magnetic optically variable pigments are widely used in various anti-counterfeiting fields. In addition to the optically variable effect of traditional optically variable pigments, magnetic optically variable pigments can also be oriented along a magnetic field. Therefore, it is necessary to form an artificially designed specific magnetic field inside the magnetic optically variable ink containing magnetic optically variable pigments during the printing and curing process, so that the magnetic optically variable pigment microchips can have different angular orientations in different regions, thereby making the magnetic optically variable Pigments create unique light-shifting pattern effects in prints. [0003] Orientation of magnetic o...
