Problems solved by technology

As a result, the fixing process will be insufficient for inks of colors that absorb less radiant heat than inks of other colors, resulting in weaker color development and / or color irregularities relative to other colors

Embodiment Construction

[0045] First, refer to figure 1 An example of the recording medium 1 handled by the image forming apparatus of the present invention will be described. The recording medium 1 includes a base sheet 10 made of a film sheet such as PET (polyethylene terephthalate), formed of, for example, urethane resin and covered on the surface of the base sheet 10 for applying ink, i.e. ink pigments. , the fixed layer 11, the surface layer 12 placed on the surface of the fixed layer 11 and used as a permeable layer allowing ink to permeate therethrough. In the case where the surface of the substrate 10 has properties allowing ink pigments to be directly fixed thereon, the fixing layer 11 may be omitted. In use, droplets of sublimation ink are applied to the surface layer 12 of the recording medium 1 by, for example, an inkjet printer to form thereon a printed image consisting of sublimated printed dots, which are then, when heated to a suitable temperature, Ink drops (non-sublimated printed ...

Abstract

An image forming device comprising a printing head (2) controllably driven according to printing data; heater means for applying thermal energy to a recording medium (1) to fix ink applied to a surface layer thereof by the printing head to a fixed layer thereof (HU); and a controller (7) for generating print data from image data. The controller (7) includes a deformation compensating part (9) for compensating the offset between the target image and the fixed image caused by longitudinal and / or lateral direction of the recording medium associated with thermal energy applied thereto Caused by the dimensional change on the surface; the fixed color rendering performance compensation component (92), which performs fixed color rendering performance compensation according to the fixed color rendering performance of the ink determined by thermal energy for the fixed layer during the process of generating printing data from image data; And a thermal absorptivity compensating part (96) for compensating a color-dependent difference in thermal absorptivity to the radiant heat beam in the process of generating printing data from the image data.

Description

technical field [0001] The present invention relates to an image forming apparatus using heat sublimation technology, comprising a printing head controllably driven according to printing data and heating for applying thermal energy to a recording medium to fix ink applied to a surface layer thereof by the printing head to a fixed layer thereof device. Background technique [0002] A typical conventional technique related to the above technical field is disclosed in Japanese Patent Application "Kokai" No. Hei 10-297197. According to this technique, a metal substrate includes a colored underlayer serving as an antirust layer and a transparent resin layer formed on the colored underlayer as a light-transmitting resin layer made of acrylic resin, polyester resin, polyurethane resin, etc., And also includes an ink receiving layer formed on the resin layer, for example, made of porous alumina. After the sublimation ink or pigment is applied on the ink receiving layer by inkjet p...
