Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
An embodiment of the present invention provides a printing control method for a PCB character, as shown in fig. 1, the method includes:
s1, dividing the data to be printed into character data and color block data;
the print data of the PCB character printer is generally Gerber file, the Gerber file is ASCII code file, the data is firstly analyzed after the Gerber file is read, and the analyzed data can be classified into a plurality of designated primitives, such as points, straight lines, rectangles, circles, circular arcs, outlines (any polygons), round-head rectangles, any outlines (including ellipses) and the like. The primitives are color blocks if filled and characters if unfilled, so that color block data and character data can be separated according to primitive types.
In this embodiment, the character data may be print data in which the ink discharge amount of the nozzle is smaller than a first preset value during printing, so as to ensure that the printing effect of the character data is fine and smooth ink discharge and clear handwriting; the color block data can be printing data of which the ink output amount of the nozzle is greater than a second preset value during printing, so that the full ink amount of the color block or logo is ensured to be printed. The first preset value and the second preset value can be set according to actual needs.
The primitive types comprise any polygons such as points, straight lines, rectangles, circles, arcs, round-head rectangles, ellipses and the like and any outline graphs. Wherein characters, irregular figures and the like are classified into primitive types of any outlines. Each primitive type has a specified primitive data structure and is stored in a respective memory space. Any polygon such as a point, a straight line, a rectangle, a circle, a circular arc, a round-head rectangle, an ellipse and the like and any outline graph have filled images, and the filled images are color lump images. In particular, the color block images to be filled are provided with corresponding image filling marks.
In this embodiment, different primitive information may be obtained according to different obtaining conditions, for example, fig. 2a, and if a first obtaining condition is set to obtain a complete target bitmap of an image to be printed, first primitive information of a Gerber file is obtained; and in fig. 2b, setting the second obtaining condition as that the line width information is set to be less than or equal to 2mm, and extracting the primitive into a storage space corresponding to the second primitive information as long as the line width information of the primitive is within the range of the first obtaining condition.

Further, for the printing ink of different manufacturers, to ensure good printing effect of the character data and the color block data, it is necessary to establish a mapping relationship between the printing ink, the character data and the printing waveform, and a mapping relationship between the printing ink, the color block data and the printing waveform.

Specifically, the character data can be controlled to be output in the first printing direction of the nozzle, and the first printing waveform is loaded to the first printing direction of the nozzle, so that the character data can be printed in the first printing direction by adopting the first printing waveform.
Meanwhile, the color lump data can be controlled to be output in the second printing direction of the nozzle, and the second printing waveform is loaded in the second printing direction of the nozzle, so that the color lump data can be printed by adopting the second printing waveform in the second printing direction.
