A method for controlling luminance of a transmissive board at the moment of transmissive illumination, in a short time, at a low cost. The luminance of a control object is made the target luminance by a rough control step of printing ink having a constant light transmittance on a front side or a back side of the control object in a transmissive board. The rough control step is repeated a number times within a range such that the luminance does not exceed the target luminance. The ink is printed on the front side or the back side by controlling the amount of the ink to be printed to a unit area in accordance with a luminance difference between the target luminance and the control luminance which is not eliminated in the rough control step.

There are provided a method for image formation which can produce an image formed object possessing excellent fastness or resistance properties such as excellent abrasion resistance, lightfastness, and alteration preventive properties, is less likely to cause damage to an object, is free from a deterioration in image quality, and does not incur an increase in production cost, and an image formed object. In the method for image formation, an intermediate transfer recording medium comprising a substrate and a light transparent protective layer provided on the substrate, and a first thermal transfer recording medium comprising a substrate and a light transparent ink layer provided on the substrate are first provided. The intermediate transfer recording medium and the first thermal transfer recording medium are put on top of each other. The assembly is imagewise heated to form a light transparent image on the light transparent protective layer in the intermediate transfer recording medium. The intermediate transfer recording medium with the light transparent image formed thereon is put on top of a second thermal transfer recording medium comprising a substrate and a color ink layer provided on one side of the substrate. The assembly is imagewise heated to transfer the color ink layer onto the light transparent protective layer on its light transparent image-formed side, whereby a color image is formed on the light transparent protective layer. An object is then put on top of the intermediate transfer recording medium with the images formed on its light transparent protective layer. The whole assembly is heated to form a color image, a light transparent image, and a light transparent protective layer on the object.

A control section 9 of a thermal printer 1 performs CMYK/RGB-gray conversion, gradation conversion, halftone conversion for an input image data 3, and performs shift processing and rotation processing in accordance with the resolution and the number of lines of the thermal printer 1. The control section 9 performs heat-accumulation correction processing for the image data subjected to the halftone processing, and the image data subjected to the shift processing and the rotation processing, and then prints a hairline image. When a circular hairline is printed, the control section 9 defines a pattern of circular hairlines, and produces a horizontal hairline pattern. Further, the control section 9 shifts the produced horizontal hairline pattern downward to thereby produce another horizontal hairline pattern, performs polar coordinate conversion for the produced horizontal hairline patterns to thereby produce two circular hairlines, performs the heat-accumulation correction processing for the two produced circular hairlines, and prints them.

摘要:
A method of controlling the luminance of a transmissive board at the moment of transmissive illumination by providing the steps of determining a criterion number of ink transfers by roughly controlling the luminance of the highest luminance at the moment of transmissive illumination to closely reflect the lowest transmissive luminance on the board, determining the criterion area-ratio by the minor control of the luminance on the board so that the higher luminance most closely reflects the luminance of the lowest luminance on the board, and equalizing the luminance of all luminance on the board so that all luminance is controlled to be the lowest luminance of the transmissive board at the time of transmissive illumination by a light source by the transfer of ink according to a prepared processing number. Also provided is the transmissive board wherein the transmissive luminance is controlled by the method of the invention.
