The invention provides a method of preparing a hard copy by forming a transparent coating layer on a recording medium in areas where image has been recorded. The invention has the first step of causing clear droplets to fly from a recording head toward the areas where image has been recorded and the second step of curing the droplets while they are in flight and the third step of depositing the cured droplets in the image-recorded areas of the recording medium so as to form the coating layer. According to the invention, a clear coating layer over color layer can reproduce an even more accurate gloss than in the prior art and presents the desired surface properties in the absence of steps even if there is unevenness in image recording density, whereby the image has a sufficiently improved texture to look more real.

An exposure head is provided in which a deterioration in image quality, due to density non-uniformity or the like, of an image formed by using plural light beams can be suppressed. A microlens array is provided at a light-exiting side of a LED chip which has plural LED elements. The microlens array has microlenses of the same number as a number of LED elements. The microlenses are arranged in an array form at uniform intervals. The microlens array is lenses of an illumination system which, for example, limit spreading of light beams emitted from the LED chip. Light beams of homogeneous configurations and homogeneous profiles are illuminated onto a theoretical object plane at a time of focusing the light beams onto an exposure drum. In this way, the light beams emitted from the LED elements are illuminated with homogeneous configurations and at homogeneous light amount distributions onto illumination regions by the microlenses which function independently.

Respective light-emitting elements are caused to emit light at the maximum rated outputs and densities of three colors developed by a photosensitive material are made substantially uniform. The maximum rated outputs at light-emitting central wavelengths, of the three-color light-emitting elements are respectively 2.4 mW, 0.04 mW and 1.2 mW. The ratio between the outputs is represented as R:G:B=60:1:30. On the other hand, the ratio between spectral sensitivities of the most-frequently used photosensitive material is represented as R:G:B=1:30:2. An exposure-value ratio on the photosensitive material, which is synthetically obtained from these, reaches R:G:B=2:1:2. Thus, the numerical ratio among the light-emitting elements, for making exposure values uniform becomes R:G:B=1:2:1. The numbers of the respective light-emitting elements are defined so as to reach the least numbers from the numerical ratio (i.e., one R-light-emitting element, two G-light-emitting elements and one B-light-emitting element). Further, a repetition of R-G-B-G, R-G-G-B or the like is most suitable as the sequence of arrangement of the light-emitting elements.

The inkjet recording apparatus comprises: a light emitting device which illuminates filled ink with light; a measuring device which measures a spectral characteristic of one of the light transmitted through the filled ink and the light reflected by the filled ink; and a determining device which determines whether the filled ink is a specific ink according to the spectral characteristic measured by the measuring device.

In the transfer apparatus, accumulated maximum transmittance of the color filters in each of ranges, in which respective spectral transmittance curves of the color filters overlap each other, is set smaller than a predetermined value. Alternatively, a light source is produced so that a light emission peak exceeding a predetermined size does not exist in each range in which at least two of red, green, and blue spectral sensitivities of a photosensitive recording medium overlap each other. Still alternatively, at least one of wavelength and light quantity of light passing through the image display device is controlled to thereby control gray tone to be recorded on the photosensitive recording medium.
摘要:
An optical recording medium and a recording method therefor in which a recording layer group and a light-absorbing and heat-generating layer for absorbing radiated light to convert the absorbed light into heat are formed on a substrate. The recording layer group is formed of thermo-sensitive recording layers capable of recording thereon information in the form of a light signal stacked alternatingly with heat insulating layers. Laser light emitted from a luminous source in a recording apparatus is condensed through an objective lens so as to be focused on the light-absorbing and heat-generating layer, so that when heat of a predetermined quantity or more is generated by the light-absorbing and heat-generating layer, the heat reaches the recording layers successively stepwise due to the heat insulating functions of the respective heat insulating layers.
