Abstract:
1. A method for printing performed by a printing system, comprising: receiving a dataset corresponding to a printing of the printing system using a darkly pigmented toner, the printing system having an undesirable optical density printing range for the darkly pigmented toner, wherein the undesirable optical density printing range is within a midtone region between an optical density value of 0 and 1; converting the dataset to a first dataset corresponding to a first printing of the printing system using the darkly pigmented toner, and a second dataset corresponding to a second printing of the printing system using a lightly pigmented toner, wherein the first dataset avoids the undesirable optical density printing range for the darkly pigmented toner, and a combination of the first printing and the second printing provides a substantially same printed optical density corresponding to the received dataset, and converting the dataset converts a value in the dataset that is in the undesirable optical density printing range to a first value in the first dataset that is lower than the undesirable optical density printing range, and a second value in the second dataset that is higher than the undesirable optical density printing range.
