ELONGATED FLEXIBLE RECORDING MEDIUM, AND IMAGE RENDERING METHOD AND IMAGE RENDERING APPARATUS THEREWITH

摘要

An image rendering apparatus method in which an image can be rendered on a flexible recording medium by correcting for an expanded/contracted state of the recording medium, the method comprising: detecting at least two marks serving as a feature for detection in a state in which the flexible recording medium is tensioned for conveying and image rendering purposes, the marks being provided on the flexible recording medium placed in a reference state and spaced apart from each other with a predetermined spacing in at least one of a conveying direction and/or a direction perpendicular to the conveying direction; comparing a distance value between the marks measured when the flexible recording medium is tensioned and a distance value between the marks in the reference state thereby determining longitudinal and/or lateral expansion/contraction factors when the flexible recording medium is in a tensioned state; and rendering an image in accordance with a rendering pattern subjected to a deforming process so as to offset a deformation of the flexible recording medium due to the tension based on the longitudinal and/or lateral expansion/contraction factors.
