An image forming system and an image forming method thereof are provided to offer a printed matter transparently processed in a part overlapped in one page by automatically assigning weight according to a concentration value of a histogram. A controller(116) processes information for transparency change received through a user interface(110). A document storing part(114) stores a plurality of objects printed to be overlapped. An image processor(120) changes the transparency of at least one object based on information for the transparency change by the weight and composes each object into page printing data. A printer driver(130) converts the composed page printing data into printing image data. The image processor includes a histogram analyzer finding a concentration histogram of each object of the printed page, a weight calculator calculating the weight according to the concentration histogram of each object, a converter converting the transparency of each object according to the calculated weight, and a composer composing each changed object into the page printing data. |
