  • Method for forming image by thermal transfer
    Patent number: 6504560
    Abstract: A method for forming an image by thermal transfer: comprising forming a multi-color image using two chromatic color thermal transfer ink ribbons A and B, the thermal transfer ink ribbons A and B having respective chromatic colors which satisfy the following relations: YA+YB≧1.0 MA+MB≧1.0 CA+CB≧1.0 wherein YA, MA, and CA are defined respectively as values obtained by color separation of the optical reflection density of the thermal transfer ink ribbon A into Y, M, and C components, and YB, MB, and CB are defined respectively as values obtained by color separation of the optical reflection density of the thermal transfer ink ribbon B into Y, M, and C components.

  • Ribbon for smoothing print image and method for smoothing print image using the same
    Patent number: 6180173
    Abstract: A ribbon for smoothing a print image is disclosed which is used in a method which comprises bringing the ribbon into contact with a print image formed on a receptor by thermal transfer and heating the print image from the opposite side of the ribbon with respect to the side contacting the print image under pressure by means of a thermal head, thereby smoothing the print image. The ribbon has a kinetic friction coefficient, &mgr;A, on the side A thereof contacting the thermal head and a kinetic friction coefficient, &mgr;B, on the side B thereof contacting the print image, the values &mgr;A and &mgr;B satisfying the following equations: &mgr;B>1.67 &mgr;A 0.10<&mgr;B<0.
