Patent ID: 7903881

Claim:
An image processing device, comprising: a user interface including first and second display regions, the first display region configured to receive from a user a first numerical value corresponding to a first line width at which a finishing image output device will output an image that disappears or becomes blurred at the first line width, the second display region configured to receive from the user a second numerical value corresponding to a second line width, which is thicker than the first line width; an extracting section that extracts a first line image having the first line width or less from a page layout generated by an application program in reference to the first line width specified by the first display region; and an image converting section that converts the first line image extracted by the extracting section to a second line image having the second line width, the second line width being output to an image proof forming device to provide an image proof of the page layout prior to outputting to the finishing image output device, the second line image being at the second line width in the image proof.
