  • Patent number: 12214603
    Abstract: A method for enhancing resolution of a radiation sensitive microcapsule-based printer includes generating multiple subpixels in a sub-scan direction. The method further includes mapping multiple grids onto a photosensitive medium, the multiple grids corresponding to the multiple subpixels. The method further includes determining an exposure energy required for each grid of the multiple grids. The method further includes allocating the exposure energy required for each grid into a first exposure level and a second exposure level. The method further includes exposing each grid of the photosensitive medium to the corresponding first exposure level and the corresponding second exposure level sequentially as the photosensitive medium passes through the radiation sensitive microcapsule-based printer in the sub-scan direction.
