Abstract
An image forming apparatus capable of reducing a stitch effect, an image forming system including the same, and a printing method thereof. The printing method of the image forming system includes inputting image data to be printed; and, if adjacent first and second objects included in the input image data have different LPIs (Lines Per Inch), emphasizing at least one of boundaries of the first and second objects and printing the image data with an emphasized boundary.
Claims22
A printing method of an image forming system, comprising:
- inputting image data to be printed;
- and
- if adjacent first and second objects included in the input image data are halftone-processed such that the first and second objects have different halftone property, performing an emphasis process on at least one of boundaries of the first and second objects and printing the image data with an emphasized boundary.
A printing method of an image forming system, comprising:
- inputting image data to be printed;
- if adjacent pixels of the input image data belong to first and second objects, respectively, detecting the adjacent pixels as boundaries of the first and second objects;
- performing an emphasis process on the detected boundaries of at least one of the first and second objects;
- and
- printing the image data with emphasized boundaries.
An image forming apparatus comprising:
- a data input unit that receives image data to be printed;
- a printing unit that prints the image data on a print medium;
- and
- a controller that, if first and second objects included in the received image data are halftone-processed such that the first and second objects have different halftone property, performs an emphasis process on at least one of boundaries of the first and second objects and controls the printing unit to print the image data with emphasized boundaries.
An image forming system including a host device and an image forming apparatus operable to communicate with the host device,
- wherein, if first and second objects included in image data to be printed have different LPIs (Lines Per Inch), the host device performs an emphasis process on at least one of boundaries of the first and second objects and transmits the image data with the emphasized boundary to the image forming apparatus, and
- wherein the image forming apparatus prints the image data transmitted from the host device.
