Description

Printing system and printing method Technical Field One or more embodiments relate to a printing system and a printing method in which the accuracy of a printing process is improved. Background Industrial inkjet printers use not only common dyes but also metallic materials (such as copper, gold, and silver), ceramics, and polymers as printing solutions. Industrial inkjet printers may be used for industrial graphics, displays, and solar cells by printing (e.g., direct printing) on various objects such as substrates, films, fabrics, and displays. In particular, in the field of displays, processes using inkjet printers may be applied to color filter fabrication, liquid crystal alignment processes, organic emission layer fabrication, and quantum dot emission layer fabrication. A printing system configured to perform an inkjet printing operation includes an inkjet printhead including at least one ink delivery path (or nozzle). In the case where a printing system configured to perform an inkjet printing operation uses a universal inkjet driver, a uniform and consistent jetting waveform may be generated. Because a uniform and consistent jetting waveform can be used, the accuracy of the printing process may be reduced due to changes in the viscosity of the ink or expansion of the material according to temperature.

In the case where the second control command is the first signal, the driving signal may be the first driving signal including the same information as the print data. In the case where the second control command is the second signal, the driving signal may be the second driving signal including one piece of waveform information loaded from the memory based on the modulation data from among the waveform information of the prestored pieces. The print data may include position data regarding the position at which ink may be ejected from the printing device, and volume data regarding the volume of ink ejected from each nozzle included in the printing device. The modulation data may include address information that may be stored in a memory with respect to a plurality of pieces of waveform information. In the case where the second control command is a second signal, the driving signal may be a second driving signal including waveform information allocated to address information in the memory.

The spray assembly may further include a piezoelectric element layer disposed below the chamber, and a nozzle plate disposed below the piezoelectric element layer and having a bottom surface that is a bottom surface of the spray assembly. The first control command, the second control command, and the modulation data may be implemented as digital signals. The second control command may be generated based on user input that may be input to the user device. According to one or more embodiments, a printing method may include receiving print data from a controller, receiving a first control command from a user device, receiving modulated data from the user device and storing the modulated data based on the first control command, receiving a second control command from the user device, generating a drive signal based on the second control command, and transmitting the drive signal to the printing device.
