Ink jet printing control method and device
View Patent ↗An ink jet printing control method and device, the method comprising: judging whether the interval distance between a detected current color code on a print stock and the previous color code of the current color code is smaller than a time delay distance; if yes, then recording the interval distance, and printing the content corresponding to the current color code after the print stock has moved for a period of time required for the interval distance from the time when the content corresponding to the previous color code is completely printed. With the solution of the present invention, within the time when the device is waiting for the previous color code of the print stock to move for the time delay distance, recording the interval distance between the current color code and the previous color code after the current color code is detected, and printing the content corresponding to the current color code after the content corresponding to the previous color code is completely printed and the print stock has moved for the interval distance, thus avoiding the occurrence of defective prints because the current color code is not processed.
1. A method for controlling ink-jet printing, comprising:
determining whether a separation distance between a current color label detected on a print carrier and a preceding color label of the current color label is below a delay distance;
recording the separation distance if it is below the delay distance, and triggering to print, with a first print module, contents corresponding to the current color label when the print carrier moves over the separation distance starting from the end of printing contents corresponding to the preceding color label;
recording the delay distance if the separation distance is not below the delay distance, and
triggering to print, with a second print module, the contents corresponding to the current color label when the print carrier moves over the delay distance starting from the end of the printing contents corresponding to the preceding color label.
2. The method according to claim 1 , wherein the separation distance or the delay distance is recorded in the form of a First Input First Output, FIFO, queue.
3. The method according to claim 1 , further comprising:
recording an identifier of the current color label correspondingly together with the delay distance or the separation distance.
4. The method according to claim 1 , further comprising:
discarding the current color label as an interference signal upon determining that the separation distance is below a guard distance.
5. The method according to claim 1 , wherein the separation distance or the delay distance over which the print carrier moves is determined by the number of signals of an encoder.
6. An apparatus for controlling ink-jet printing, comprising:
a determining module configured to determine whether a separation distance between a current color label detected on a print carrier and a preceding color label of the current color label is below a delay distance;
a first storing module configured to record the separation distance and trigger a first printing module when a result of determination by the determining module is being below the delay distance; and
the first printing module configured to print contents corresponding to the current color label when the print carrier moves over the separation distance starting from the end of printing contents corresponding to the preceding color label;
a second storing module configured to record the delay distance and trigger a second printing module when the result of determination by the determining module is not being below the delay distance; and
the second printing module configured to print the contents corresponding to the current color label when the print carrier moves over the delay distance starting from the end of the printing contents corresponding to the preceding color label.
7. The apparatus according to claim 6 , further comprising:
a protecting module configured to discard the current color label as an interference signal when it is determined that the separation distance is below a guard distance.
