Abstract:
1. A method comprising: analyzing an image to obtain a density profile of the image, the image to be printed using an inkjet-printing device, the image not being a completely blacked out image; after analyzing the image to obtain the density profile of the image, estimating a greatest amount of current expected to be drawn by an inkjet printhead of the inkjet-printing device while printing the image, the greatest amount of current estimated based on the density profile of the image and based on a current model of the inkjet printhead, the greatest amount of current expected to be drawn by the inkjet printhead while printing the image being lower than a greatest amount of current expected to be drawn by the inkjet printhead while printing a completely blacked out image; after estimating the greatest amount of current expected to be drawn by the inkjet printhead while printing the image, and while printing the image by the inkjet printhead of the inkjet-printing device,
