Claim One:
1. A method for printing clear tagged objects on clear plane, the method being implemented in a multifunctional device (MFD) having processor, the method comprising: receiving a print job at the MFD, wherein the print job comprising a page description language (PDL) file having an input image; performing raster image processing on the input image to generate input raster buffer by converting the input image into a digital bitmap image comprised of an array of pixels, wherein each pixel being assigned with an object tag information and an object definition; determining clear objects based on the object tag information and the object definition present in the PDL file; drawing a bounding box around each block of the clear objects, wherein pixels tagged as clear objects in the bounding box are considered as foreground pixels and rest pixels in the same bounding box are considered as background pixels; for each bounding box, computing occupancy percentage of the foreground pixels representing the clear objects against the background pixels; applying dilation on the pixels representing the clear objects when the computed occupancy percentage is below a threshold value; tagging the pixels, representing the clear objects, which are dilated as dilated pixels of the clear objects; determining an amount of flood clear selected for the application on the input image; for each of the dilated pixels and based on the amount of the flood clear, modifying pixel values of the dilated pixels of the clear objects in the input raster buffer to bring the dilated pixels in the range of visibility of clear ink value; converting the input raster buffer into a ready-to-print (RTP) format; and generating a print document at the MFD based on the RTP format.
