1. A method for producing a hard copy using a hard copy producing device by recording an image on a recording medium according to an image signal which represents an image density of the image to be recorded, comprising the steps of: recording the image on said recording medium according to the image signal using an image recorder; applying a surface roughness control, using a surface roughness control device, to an image area on said recording medium on which the image is recorded; and correcting, using a correcting device, before recording the image on said recording medium, the image signal used for the recording so that a viewed image density provided after the surface roughness control equals the image density of the image to be recorded, said correcting using information on a density difference between an image density before the surface roughness control and a viewed image density after the surface roughness control.
