1. A method of printing on a receiver an image in the form of a page description language (PDL), the method comprising: rasterizing the image in the form of the PDL to produce a digital bitmap including an array of pixels, each pixel having a respective multi-bit digital value representing marking information; identifying pixels in the rasterized digital bitmap that are part of one pixel wide structures; adjusting the respective multi-bit digital values of the pixels so identified to alter the appearance of the image when printed, wherein the respective multi-bit digital values of the identified pixels in the rasterized bitmap are adjusted to multi-bit digital values of decreased value so those pixels appear thinner when printed; and depositing marking material corresponding to the adjusted rasterized bitmap including the adjusted digital pixel values on the receiver using a printer, wherein the rasterizing step includes applying a halftone screen to produce the digital bitmap.
