Abstract: In some examples, a system detects a highlighted area in an image content, the highlighted area including a portion of the image content, and a highlighting mark that highlights the portion of the image content. The system applies a color adjustment process in the highlighted area, wherein the color adjustment process comprises adjusting a color of the highlighted area comprising the portion of the image content highlighted by the highlighting mark, and wherein the adjusting of the color of the highlighted area comprises adjusting color values of plural color components in a first color space.

Abstract: In one example in accordance with the present disclosure, a printing device is described. The printing device includes a print controller with a processor and memory. The print controller generates print instructions. Specifically, the print controller receives print image data representing an image to be printed and identifies enclosed regions in a background print agent plane. The print controller also determines a size of the enclosed regions of background print agent plane and responsive to the size of an enclosed region being smaller than a threshold size, removes the enclosed region from the background print agent plane. The printing device also includes a print agent distribution system to apply the background print agent and the image print agent to a substrate according to the print instructions.
