  • Patent number: 6634743
    Abstract: A method for increasing the diameter of an ink jet ink dot resulting from the application of an ink jet ink drop applied to the surface of an inkjet recording medium having a support having thereon an image-receiving layer and an overcoat layer, the ink penetration rate of the overcoat layer being faster than the ink penetration rate of the image-receiving layer; having the steps of: a) applying the overcoat layer on top of the image-receiving layer at a thickness less than the maximum thickness, the maximum thickness being that thickness whereby an ink jet ink drop applied to the surface of the overcoat layer will not substantially penetrate the surface of the image-receiving layer; and b) applying the ink jet ink drop on the surface of the overcoat layer whereby the diameter of the ink jet ink dot is increased relative to that which would have been obtained if the overcoat layer had been coated at a thickness of at least the maximum thickness.
