Zusammenfassung:	Methods and systems for generating a mixed raster content (MRC) format file are disclosed. The method includes receiving an input document. The input document is segmented into an image layer and a text layer with a color mask information. A determination is made whether a text group in the text layer has a color different than the color mask information. Upon an affirmative determination, an ascertainment is made whether the color mask is above a threshold value. An average of the color mask is calculated and based on the calculation, a new color is applied to the text group to modify the text layer. Then, the modified text layer is compressed using a first compression scheme, the image layer is compressed using a second compression scheme, the compressed the modified text layer and the image layer are integrated to generate an image data in an MRC file format.
