Abstract
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.
