technical field

The invention relates to the technical field of printing, in particular to an inkjet printing method and device.

Background technique

Inkjet printing is a non-contact, pressure-free, and plate-free printing technology. The information stored in the electronic computer can be input to the inkjet printing machine to realize printing.

Inkjet printing machine is composed of system controller, inkjet controller, nozzle, substrate and driver.

detailed description

The technical solution of the present invention will be described in further detail below through specific embodiments and accompanying drawings.

Fig. 1 is a schematic flow chart of an embodiment of the inkjet printing method provided by the present invention. As shown in Figure 1, the method may specifically include:

S101. Obtain an electronic file to be printed.

Specifically, the electronic file in this embodiment may specifically be a Portable Document Format (Portable Document Format, PDF for short) file, a DOC file, a PS file, and the like. Among them, the PDF file is based on the PostScript language image model, which can encapsulate text, font, format, color, and graphic images independent of equipment and resolution in one file, and can ensure accurate printing no matter what kind of printing machine it is on. Color and accurate printing, that is, the PDF faithfully reproduces every character, color, and image of the original. Therefore, the specific implementation process of this step can include the following two methods: for electronic files whose data source files are PDF files, they can be processed directly; for electronic files whose data source files are other formats, such as DOC files and PS files, etc. , you need to convert it to a PDF file first, and then process the converted PDF file.

S102. Divide each data in the electronic file into at least two groups of data according to types, and the number of data groups is the same as the number of nozzle groups in the inkjet printer.

Specifically, this step is used to divide different types of data in the electronic file, and in order to make different types of data printed and output by different nozzle groups of the inkjet printer, the number of divided data groups should be the same as the number of nozzle groups . The inkjet printing machine in this embodiment needs to be configured with at least two nozzle groups according to the actual situation. Each nozzle group generally includes four nozzles of cyan, magenta, yellow and black to accurately describe a color image.

In this step, the process of dividing different types of data in the electronic file may specifically be: dividing each data in the electronic file according to data format and/or color coverage area.

Wherein, dividing each data in the electronic file according to the data format may specifically include: dividing each data in the electronic file into image data, text data and/or graphic data, and marking them. Specifically, the following two methods can be used to add logos: one is to directly add the logo information "image", "text" and "graphics" in the electronic file; the other is to convert the electronic file into an intermediate file, Add identification information "image", "text" and "graphics" to the file.

Dividing each data in the electronic file according to the color coverage area may specifically be: dividing each data in the electronic file into large-area solid color data and general object data, and marking them. Specifically, the following two methods can be used to add logos: one is to directly add the logo information "large-area solid color" and "general object" to the electronic file; the other is to convert the electronic file into an intermediate file and add Add identification information "Large Area Solid Color" and "General Object".

In practical applications, it is necessary to determine the appropriate division method according to the number of nozzle groups in the inkjet printer. For example, if the number of nozzle groups is 2, each data in the electronic file can be divided only according to the color coverage area to obtain 2 sets of data: a set of "large-area solid color" data and a set of "general object" data. For example, if the number of nozzle groups is 3, each data in the electronic file can be divided only according to the data format to obtain 3 sets of data: a set of "image" data, a set of "text" data and a set of "graphic" data. For example, if the number of nozzle groups is 6, each data in the electronic file can be divided into two according to the data format and color coverage area to obtain 6 groups of data: a group of "image" and "large-area solid color" data, a group of " Image" and "general object" data, a set of "text" and "large area solid color" data, a set of "text" and "general object" data, a set of "graphics" and "large area solid color" data, a set of " Graphics" and "General Objects" data. For example, if the number of nozzle groups is 4, the data in the electronic file can be divided into two according to the data format and color coverage area to obtain the above 6 groups of data, and the data of similar types can be combined into a group of data, for example, " Image" and "large-area solid color" data, "text" and "large-area solid color" data, and "graphics" and "large-area solid color" data are combined into one group, and the remaining three groups are used as four groups to be processed later data.

S103. Carry out lattice processing on each set of data to obtain a one-bit lattice file group whose number is the same as that of the sprinkler head group.

Specifically, since the inkjet printing machine cannot directly process each data in the electronic file, it is necessary to perform dot matrix processing on each group of divided data, that is, to convert the electronic file described by the vector into the data that the inkjet printing machine can receive. One-bit dot matrix file group, each set of data corresponds to one one-bit dot matrix file group, that is, the number of one-bit dot matrix file groups is the same as the number of nozzle groups. Correspondingly, each one-bit dot matrix file group generally includes four dot matrix files of cyan, magenta, yellow and black, which are used to accurately describe a color image.

S104, sequentially transmitting the one-bit dot matrix file groups whose number is the same as the number of nozzle groups to the corresponding nozzle groups for printing.

Specifically, at least two one-bit dot matrix file groups after dot matrix processing are sequentially transmitted to the corresponding nozzle groups for printing, so that different types of data can be printed and output by different nozzle groups of the inkjet printing machine, improving Printing speed and print quality.

In the inkjet printing method provided in this embodiment, by dividing each data in the electronic file to be printed, and printing and outputting the divided data of different types through different nozzle groups, it realizes the concurrent operation of multiple workflows and improves the printing speed and printing quality.
