  • Pattern printing system and data processing method thereof
    Patent number: 8248656
    Abstract: A pattern printing system and data processing method thereof are disclosed, which are suitable for printing patterns on printed circuit boards or data format rearrangement printing used in displays. The pattern printing method includes a process for interpreting scription data into matrix data, a procedure for modulating the print head resolution and the printing resolution, a procedure for interpreting and transmitting data commands, a procedure for rearranging memory data, and a procedure for firing data synchronously so as to achieve high-resolution printing and to continuously modulate any print data.

  • INK-JET SYSTEM AND INK-JET CONTROL METHOD
    Publication number: 20080018681
    Abstract: An ink-jet system and an ink-jet control method are provided. The ink-jet system mainly includes an ink-jet head, a feedback unit and a frequency eliminator. The feedback unit provides a feedback signal to the ink-jet head as the ink-jet head performs jet printing. Next, the frequency of the feedback signal is eliminated by the frequency eliminator to produce a driving signal. Then, the ink-jet head is controlled to perform ink-jetting according to the driving signal. The frequency of the feedback signal is higher than that of the driving signal, and the frequency of the feedback signal is divisible by that of the driving signal. The ink-jet system and the ink-jet control method meets high precision and high speed ink-jet requirements and are capable of fabricating patterns with different resolutions.
