Abstract:
A heating apparatus includes an emitter that emits light to a thermal expansion sheet that expands according to a heating amount absorbed, the light being converted into heat by the thermal expansion sheet; a relative mover that causes the thermal expansion sheet to move relative to the emitter in a predetermined direction or that causes the emitter to move relative to the thermal expansion sheet in the predetermined direction; and a controller that gradually changes an amount of the light emitted by the emitter according to a rise in temperature in the emitter, the rise in temperature being caused by the emission of light by the emitter, when the relative mover causes the thermal expansion sheet to move relative to the emitter in the predetermined direction or causes the emitter to move relative to the thermal expansion sheet in the predetermined direction while the light is being emitted by the emitter.
Abstract:
A printing method includes the steps of: printing a predetermined pattern on a distendable sheet before distending; distending the distendable sheet printed the predetermined pattern; calculating a displacement amount of the predetermined pattern between before and after the distending of the distendable sheet; deforming an original image by a deformation amount determined based on the calculated displacement amount; and printing the deformed original image as an image for printing on the distendable sheet.
Abstract:
When a heat capacity of a recording medium having a base material coated with a foamable resin layer is larger than a normal heat capacity, to form a raised amount equal to that with the normal case with a normal heating quantity, a turned mirror image of the image is generated. The image is transferred onto the front face of the recording medium and fixed. The recording medium is reversed, and conveyed again to the transfer part. The turned mirror image is transferred onto the rear face of the recording medium and fixed. The recording medium is heated with the heat quantity equal to that in the normal case, and combination of heat absorbed by the turned minor image and heat absorbed by the image is transmitted to the foamable resin layer to expand the foamable resin layer.

Abstract:
An ink is used for forming a photothermal conversion layer used for causing expansion of at least a portion of a thermal expansion layer of a thermal expansion sheet. The ink includes (i) an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum, and (ii) a base that is transparent to visible light.
