Description

TECHNICAL FIELD

[0001] The present invention relates to a printing control system, more particularly, to a printing control system capable of reducing the number of signal transmission contacts and avoiding signal transmission errors by transmitting electronic signals in time division. BACKGROUND

[0002] Inkjet printing, commonly known as "Inkjet Printing", is a widely used printing technology, which can be traced back to the 1950s when the British HP company (Hewlett-Packard) invented inkjet printing technology. Since then, inkjet printing technology has developed rapidly, making inkjet printers the mainstream technology for home and commercial printing. Inkjet printers have many advantages, including: low cost, especially in terms of economic advantages for home and small business use; high printing quality, which can provide high resolution and high quality images, especially in terms of photos or pictures; easy to use, inkjet printers are easy to install, and most inkjet printers can be printed through a computer or mobile device. In recent years, the rise of multi-function devices (including fax, photocopying, scanning) has rapidly expanded the flexibility of office paperwork.

[0003] The existing inkjet printing technology is increasingly diverse in application, and the printing quality is also increasingly improved. However, at the same time, in order to respond to the improvement of printing quality, the types of electronic signals delivered from the inkjet printer to the inkjet chip on the ink cartridge to control the printing process are increasingly complex, and the size of the information carried is also increasingly complex, so that the inkjet chip needs to increase additional electronic contacts to respond to the above-mentioned electronic signals. Please refer to Figure 1 In the currently known inkjet printer with a printing control module 1, there are a plurality of printing control contacts 1a, each of which transmits identification signals, first clock signals, second clock signals, first data signals, second data signals, control signals and other electronic signals to the inkjet chip 2. The corresponding setting of the ink point control contact 2b allows the ink point control module 2a to coordinate the inkjet chip 2 to perform inkjet printing according to the control signal and the first data signal, the second data signal.

[0004] However, the above-mentioned electronic signal transmission method will make the inkjet chip 2 have to set more ink ejection control contacts 2b in order to receive more and more complex electronic signals, and the greater the number of ink ejection control contacts 2b, the higher the cost of the inkjet chip 2 in the manufacturing and packaging process, and when an error occurs in the manufacturing and packaging process, the corresponding electronic signal cannot be transmitted (or transmitted incorrectly), which will affect the quality of the final printing (or the ink cartridge cannot be used directly). Therefore, in view of the prior art and the market, it is still necessary to improve the signal transmission method of the known inkjet printer or inkjet device having an inkjet control module 1 so that the required electronic signal can be transmitted more efficiently. How to improve the known technology has become the subject of the present application. SUMMARY

[0005] The main purpose of the present application is to provide an inkjet control system arranged in an inkjet device (such as an inkjet printer), which is controlled by a clock signal to transmit electronic signals in time-sharing mode, so that multiple electronic signals can share one transmission contact (IC Pad), so that the transmission contact does not need to be arranged as one electronic signal corresponding to one transmission contact as in the prior art, thereby reducing the number of transmission contacts in the inkjet device and the inkjet chip, reducing the manufacturing and packaging cost, reducing the error opportunity in the manufacturing and packaging process of the inkjet control system and the inkjet chip, increasing the reliability of the inkjet printing technology, and maintaining the high resolution and high quality image performance of the prior art. The purpose of the present application is achieved, and the detailed technical solutions are described as follows.

[0006] A general embodiment of the present application provides an inkjet control system arranged in an inkjet device, comprising: an output module having a plurality of inkjet control contacts; a clock module coupled to the output module to transmit a clock signal; a data module to provide a first data signal and a second data signal; an identification module coupled to the output module and the data module to transmit an identification signal and the first data signal in time-sharing mode according to the clock signal; and a control module coupled to the output module and the data module to transmit a control signal and the second data signal in time-sharing mode according to the clock signal; wherein the output module transmits the clock signal, the first data signal, the second data signal, the identification signal, and the control signal to an external terminal through the inkjet control contacts.

[0007] According to the content of the present application, the external terminal transmitted by the output module is an inkjet chip arranged on an ink cartridge and having an ink ejection control module and a plurality of ink ejection holes. The ink ejection control module is used to control the ink ejection holes of the inkjet chip to eject ink for inkjet printing operation according to the clock signal, the first data signal, the second data signal, the identification signal, and the control signal.

In addition, the present application can be applied and carried out by other embodiments, and each detail described in the specification can be applied based on different requirements, and various modifications or changes can be made without departing from the spirit of the present application. Therefore, the present application will be described with reference to the preferred embodiments and examples, and such description is to explain the structure of the present application, and is used to illustrate but not to limit the scope of the present application. The terms used in the following description will be interpreted in the broadest reasonable manner, and can be used together with the detailed description of a certain embodiment of the present application. Those skilled in the art can adjust the structure of the present application to meet the requirements of actual industry, and the present application is described in advance. In the present application, the clock signal, the first data signal, the second data signal, the identification signal, and the control signal can be collectively referred to as electronic signals. Those skilled in the art can understand the present application after reading the specification and drawings, and the present application is used to illustrate but not to limit the scope of the present application.

[0033] According to an embodiment of the present application, please refer to Figure 2 and Figure 3The present application provides a printing control system 200, which is arranged in a printing device, and comprises an output module 250 having a plurality of printing control contacts 250a; a clock module 210 coupled to the output module 250 for transmitting a clock signal; a data module 230 for providing a first data signal and a second data signal; an identification module 220 coupled to the output module 250 and the data module 230 for transmitting an identification signal and the first data signal in time according to the clock signal; and a control module 240 coupled to the output module 250 and the data module 230 for transmitting a control signal and the second data signal in time according to the clock signal; wherein the output module 250 transmits the clock signal, the first data signal, the second data signal, the identification signal, and the control signal to an external terminal through the printing control contacts 250a. In some embodiments, the external terminal can be an ink chip 300 arranged on an ink cartridge. In addition, according to the embodiments of the present application, the clock module 210 can be selected from a single-phase timer, a two-phase timer, a four-phase timer, or a timing multiplier, thereby generating the clock signal. In one embodiment, the clock module 210 can be a two-phase timer, which transmits a first clock signal and a second clock signal, so that more than two electronic signals or data streams can be transmitted through one communication line according to the phase of the clock signal. The first clock signal, the second clock signal, and the nth clock signal can be collectively referred to as the clock signal, which depends on the selection of the number and form of the phases of the clock module 210.

[0034] According to the present application, the clock signal is used to provide phase information, so that the elements in the system can operate in coordination according to the phase information; the identification signal is used to provide a signal for identifying the elements in the system, so that the inkjet printing devices (such as an inkjet printer and a corresponding ink cartridge) can identify the compatible printing system for cooperative operation (such as the ink cartridge serial number, the ink type, the ink capacity, the ink color, the matching information between the ink cartridge and the inkjet printer, etc.); the first data signal and the second data signal can be collectively referred to as the data signal, which is used to provide the information of the printing pattern or text required for inkjet printing; and the control signal is used to provide the control information of the external terminal. In one embodiment of the present application, if the external terminal is an ink cartridge, the control signal is used to control the ink for printing.

[0035] According to the present application, since the clock signal can provide phase information, the identification module 220 integrates the identification signal and the first data signal, and the control module 240 integrates the control signal and the second data signal, when transmitting the electronic signals, the output module 250 can coordinate the transmission of the identification signal and the first data signal on the same communication line to the external terminal according to the phase information of the clock signal, and the transmission of the control signal and the second data signal is the same, so that the inkjet control system 200 can transmit the first data signal, the second data signal, the identification signal, and the control signal to the external terminal according to the need of electronic signal transmission during inkjet printing. In this way, when the quality of inkjet printing is improved, and the types of electronic signals and the size of information carried are increasingly complex, two or more electronic signals or data streams can be transmitted on one communication line according to the phase of the clock signal, which allows the same inkjet control contact 250a on the output module 250 to transmit the identification signal and the first data signal, or the same inkjet control contact 250a to transmit the control signal and the second data signal, reducing the number of inkjet control contacts 250a in the output module 250, achieving the purpose of the present application by transmitting electronic signals in time-sharing mode, allowing multiple electronic signals to share one transmission contact (IC Pad). In addition to reducing the cost of manufacturing and packaging, it can also reduce the error opportunities in the above process, increase the reliability of the inkjet control system 200, while maintaining high resolution and high-quality image performance, achieving the purpose of the present application.

[0036] In an embodiment of the present application, when the external terminal transmitted by the output module 250 is an inkjet chip 300, the inkjet chip 300 is arranged on the ink cartridge and has a dot control module 310, a plurality of dot control contacts 310a, and a plurality of nozzles 320. The dot control contacts 310a are coupled to the corresponding inkjet control contacts 250a according to the type of electronic signal transmitted, so that the output module 250 can transmit the first data signal, the second data signal, and the identification signal to the dot control contacts 310a through the inkjet control contacts 250a according to the clock signal, so that the dot control module 310 can control the nozzles 320 to perform inkjet printing according to the above-mentioned electronic signals.

[0037] As described above, please refer to Figure 4 、 Figure 5 , and Figure 6 In an embodiment of the present application, the control module 240 in the inkjet control system 200 has different printing modes for controlling the arrangement of the nozzles 320. For example, please refer to Figure 4 In an embodiment of the present application, the control module 240 can control the nozzles 320 arranged in a double-row parallel structure; or, please refer to Figure 5In another embodiment of the present application, the control module 240 can control the nozzles 320 to present a double-row staggered structure; or, please refer to Figure 6 In yet another embodiment of the present application, the control module 240 can control the nozzles 320 to present a single-row structure. According to one aspect of the present application, if the double-row parallel structure and the double-row staggered structure, the printing control system 200 can control the same printing point to have two nozzles 320 to perform inkjet printing, so that in addition to making the color more vivid and detailed when printing, it can also make the pattern after printing present a more layered visual effect according to the needs of the industry; on the other hand, if it is a single-row structure, the same printing point at this time has one nozzle 320, so that in addition to saving the required ink when printing, the printing control system 200 can select the inkjet printing form according to the printing conditions required in the application situation. Among them, the printing range that the printing control system 200 can control is between 23900μm-27000μm, and the corresponding resolution DPI (Dots Per Inch, the number of dots per inch) range is between 150 and 48000DPI.

[0038] According to the embodiment of the present application, the printing control system 200 can control 1-6 colors. In one embodiment of the present application, single-color ink can be controlled, and the single-color ink can be cyan (C: Cyan), magenta (M: Magenta), yellow (Y: Yellow), and black (K: Black) ink, respectively. In other embodiments of the present application, it can be 6 colors, controlling black (K: Black), cyan (C: Cyan), magenta (M: Magenta), yellow (Y: Yellow), light cyan (LC: Light Cyan), and light magenta (LM: Light Magenta) six-color ink, respectively. Of course, in another embodiment, the printing control system 200 can also control 4 colors, providing cyan (C: Cyan), magenta (M: Magenta), yellow (Y: Yellow), and black (K: Black) four-color ink. Among them, the number of colors or color types described above can be replaced or modified according to the actual application design requirements.

[0039] In summary, the present application provides a printing control system, which is arranged in a printing device (such as an inkjet printer), and is controlled by a clock signal to transmit electronic signals in a time-sharing manner, so that multiple electronic signals can share one transmission contact, thereby reducing the number of transmission contacts in the printing device and the inkjet chip. In addition to reducing the packaging cost, the present application can also reduce the error opportunities in the manufacturing and packaging process of the printing control system and the inkjet chip, increase the reliability of the inkjet printing technology, maintain the high resolution and high-quality image performance in the prior art, and have high industrial applicability. The present application can be modified by those skilled in the art, but all modifications shall not deviate from the protection scope defined in the appended claims.
