Abstract: The present invention relates to a lithographic printing method that uses inks selected from amongst yellow, magenta, cyan and black inks, the method comprising using yellow, magenta, cyan and black inks for which the number of representable colors obtained when printing the yellow, magenta, cyan and black inks with the density values for the yellow, magenta and cyan inks set to standard density values is at least 1.1 times the number of representable colors obtained when printing yellow, magenta, cyan and black Japan Color standard inks with the density values for the yellow, magenta and cyan Japan Color standard inks set to standard density values, and printing the yellow, magenta, cyan and black inks with the density values for the yellow, magenta and cyan inks set to 1.0 to 1.5 times the standard density values. The standard density values are from 1.40 to 1.44 for yellow, from 1.52 to 1.56 for magenta, and from 1.63 to 1.

Abstract: An image-transfer apparatus equipped with a smoothing device (roller), which device, when an image-forming material is attached to a platen, prevents the formation of a crinkle in the image-forming material thereby to remove a deviation in registering (positioning) the image-forming material, and an image-transfer method using the above imge-transfer apparatus.

Abstract: A method of forming an image which comprises subjecting an image-forming material comprised of a substrate and a photosensitive layer containing a dye and/or a pigment and a photopolymerizable compound and disposed on the substrate to an image-exposure, thereby to allow the exposure to cause a difference of adhesion between an exposed portion and non-exposed portion in the photosensitive layer, and transferring the image to an image receptor on the basis of the difference of adhesion; wherein the photosensitive layer of the exposed image-forming material and the image receptor are allowed to face each other and directed into the nip between two rollers consisting of an elastic roller and a metallic roller having a surface temperature of between 50.degree. C. and 150.degree. C.
