Abstract: Methods and systems for printing clear tagged objects on clear plane are described herein. In an example, the system draws a bounding box for each block of text/graphic objects. Within each bounding box, an occupancy percentage of foreground pixels (tagged as clear objects) is computed against background pixels. If the computed occupancy percentage falls below a defined threshold value, then that text/graphic object is considered for application of dilation. Thus, the device described herein doesn't check the size of the text/graphic objects; rather checks for the occupancy percentage of the text/graphic objects within a bounding box. While constructing the clear plane to support flood clear, the clear values corresponding to the dilated pixels (pixels considered for dilation) will be intelligently modified. In this way, only intended and logically desired text/graphic objects undergo for dilation.
