摘要： An image recording apparatus and method performs recording by making an ink adhere to a recording medium according to the blot ratio of a recording medium, when using an ink droplet or heat sensitive ink. Input recording data is discriminated based on a predetermined reference value based on the blot ratio and when the image data is larger than the reference value, the image data is reduced in order to reduce the ink dot size. Reducing the ink dot size at a recording boundary improves the quality of the image recorded at the recording boundary.
