1. A method for resolution conversion of Magnetic Ink Character Recognition (MICR) content in an image, the method being implemented in a computer system comprising one or more processors configured to execute one or more computer program modules, the method comprising: receiving, at a processor, image data of the image, the image data having a plurality of image planes in which one plane is a MICR image plane, wherein the plurality of image planes have essentially the same input resolution; and performing pattern-based conversion, using the processor, of the input resolution of the MICR image plane to an output resolution, the output resolution of the MICR image plane being essentially the same as a MICR print engine's resolution that is different from that of the remaining image planes, wherein the remaining image planes have the same input and output resolutions.
