Superfine carving method of small characters

Abstract

The invention relates to a superfine carving method of small characters, which comprises the following steps of: separately carving a pattern carved by an electric carving machine during makeup; adjusting a carving head of the carving machine, and setting an AC signal on a P card; retracting sliding feet to enable the current to be maintained within a balance range, and trying to carve; detecting whether the width of the highlight slot and a normal highlight value are the same, maintaining the current within the balance range, and if yes, completing carving; retracting to the trial carving position and trying to carve again after carving is completed, measuring whether the width of the highlight slot is changed, and if not, completing carving. In the invention, a DC control signal of the original carving current is used for carving, the pattern carved on a copper layer is formed from slots with different lengths rather than traditional net points, and the edge is neat. The space of the original net wall is also carved into an ink holding slot, so the ink quantity of the same characters is two times of the original ink quantity. Meanwhile, printing resistance can achieve nearly two times of normal carving, the ink quantity is two times of normal value, and the printing effect of characters is clear and real.

Description

technical field [0001] The invention relates to an engraving method, in particular to an ultra-fine engraving method for tiny characters. Background technique [0002] There are small dots of different sizes on the edge of the text engraved by the current electric engraving machine, which makes the lines and text appear faint. When the text line is small to a certain extent (less than 0.2mm), most of the strokes of the text will be composed of non-solid dots, and the printing effect of the text will be very poor. If the substrate is paper, it will be almost impossible to recognize the printed text. The reason for this phenomenon is determined by the working mechanism of the electric engraving machine we use. Usually our solution is to try our best to use high line count technology to ensure the edge effect of the text, but it brings about the reduction of the ink content of the text, and the strokes of the text are not printed realistically, so we can only take into account...
