Abstract
A method for printing including disposing a first ink onto a substrate to form a first ink layer on the substrate in an area where a diagnostic image will be printed; disposing a second ink onto the first ink layer to form a second ink diagnostic image, wherein the first ink has a first color density and the second ink has a second color density that is different from the first ink color density, wherein the second ink drops hit and displace areas of the first ink layer creating holes which provide a density contrast; curing or drying after forming the second ink diagnostic image; wherein the second ink diagnostic image is rendered visible by the contrast between the second ink diagnostic image and the substrate as compared to the first ink layer and the substrate.
