[0055] In an exemplary embodiment, the position of the intaglio cursor mold on the surface of the printing plate cylinder 102 can be set according to the position of the cursor 105 to be printed on the printing substrate 103. For example, the intaglio cursor mold is set on the arc surface of the printing plate cylinder 102 near the end region.

[0056] In an exemplary embodiment, an ink tank is provided below the printing plate cylinder 102.

[0057] In an exemplary embodiment, the ink tank is provided with ink for printing the cursor 105, and the color of the ink can be configured accordingly according to the color of the cursor 105.

[0058] In an exemplary embodiment, the ink in the ink tank is liquid ink.

[0059] In an exemplary embodiment, when the printing plate cylinder 102 rotates, the intaglio cursor mold is immersed in the ink tank, that is, through the rotation of the printing plate cylinder 102, the intaglio cursor mold on the surface of the printing plate cylinder 102 is immersed in the ink in the ink tank, and then the intaglio cursor mold continues to rotate with the printing plate cylinder 102 and disengages from the contact with the ink in the ink tank.

[0060] In an exemplary embodiment, a scraper is further provided below the side of the printing plate cylinder 102.

[0061] In an exemplary embodiment, the scraper is used to scrape off the ink on the surface of the printing plate cylinder 102 in the area other than the intaglio cursor mold.
