Method and apparatus for forming an image on a recording medium with contraction and expansion properties |
摘要 |
The invention provides an image forming method and apparatus capable of forming an image with a desired shape at a correct position on a recording medium having expansion and contraction properties. Boundary lines formed on the recording medium being conveyed are detected by a sensor. Distortion of the recording medium is evaluated on the basis of the detected boundary lines. Image data is corrected in accordance with the result of the evaluation and an image is formed in accordance with the corrected image data. In the above process, image data within the respective areas surrounded by the boundary lines is deformed such that the image is printed at a correct location even when the recording medium has distortion due to expansion/contraction.
