A system and method for rendering an image file for outputting a copy of an image represented by the image file. In some embodiments, rendering the image includes generating an output file, such as an output bitmap based on a predetermined halftone. In one embodiment, the system comprises an input module, and a processor. The input module obtains a page description of the image to be output. In some instances, the page description includes one or more level masks designed to impart corresponding transparency levels to one or more objects in the page description. The processor (i) detects the one or more level masks in the page description, (ii) determines the one or more corresponding transparency levels of the one or more detected level masks, (iii) obtains one or more custom masks that correspond to the same one or more transparency levels as the one or more detected level masks, wherein the one or more custom masks are designed based on the predetermined halftone, and (iv) replaces the one or more level masks in the page description with the corresponding one or more custom masks.
