Abstract: The disclosure discloses methods and systems for handling drifting of colors in printing. The method includes receiving a document including the image for printing, the image includes one or more gray and non-gray portions. An input from a user to selectively adjust the color of the gray portions of the image is received. The gray portions of the image are identified. Then, color values associated with the identified gray portions of the image are determined. Based on the user input, the determined color values associated with the gray portions of the image are selectively adjusted, without affecting non-gray color portions of the image to generate an updated image. The updated image is printed and the printed image includes adjusted color for the gray portions of the image such that gray color in the printed image is consistent with gray color of the image in the document.
