摘要： A print head apparatus capable of temperature sensing is provided. The print head apparatus includes an ink ejector coupled to an enabling signal and a selection signal for selecting the ink ejector. The ink ejector includes a nozzle, a heating module for selectively heating ink in the ink ejector so that ink droplets are ejected from the nozzle, and a temperature sensing module for selectively producing a measured temperature signal indicative of a temperature of the ink in close proximity to the nozzle. When the enabling signal is active, and the selection signal is active and indicates that the ink ejector is selected, the heating module heats up the ink in the ink ejector so that the ink droplets are ejected from the nozzle. When the selection signal is active and indicates that the ink ejector is selected, the temperature sensing module outputs the measured temperature signal indicative of the temperature of the ink in close proximity to the nozzle. By applying the invention to an inkjet print head with a plurality of nozzles, the temperature of each nozzle can be obtained selectively.

摘要： A method and apparatus for use in inkjet printing. The apparatus includes a memory, a heat accumulation calculation device, and an image separating device. The memory is used to store a heat weighting look-up table. When data representative of the image is fed into the heat accumulation calculation device, a heat weighting for the image can be calculated according to the heat weighting look-up table, which can be used to determine the degree of heat accumulation during printing. The image separating device then outputs pieces of image data representing sub-images according to the heat weighting for the image. Finally, the image is formed by printing the sub-images successively according to the pieces of image data. In addition, for some regions where serious heat accumulation is predicted, the densities of the pixels to be printed within the regions can be adjusted to reduce the degrading effect on the printing quality due to the heat accumulation during printing.

The thermal print head includes a plurality of heaters which are used to heat color dye so as to deposit the color dye on a paper to form a line image. The line image contains a plurality of pixels, each formed by one heater. When generating a pixel, a pulse sequence is fed to one heater to control the heater″s heating period. The pulse sequence contains first and second portions. The first portion contains a plurality of consecutive pulses which is used to generate a first gray level. And the second portion contains at least one empty pulse period followed by at least one pulse which is used to generate a second gray level. The combination of the first and second gray levels will determine the gray level of each pixel of the line image.
