摘要： An image processing method including calculating a density of a character to be recorded based on information of a type, size and line width of the character; adjusting an irradiation energy of a laser beam for recording the character based on the density of the character; and irradiating a recording medium with the laser beam whose irradiation energy is adjusted so as to record the character thereon.
The method finds application in printing of characters on thermoreversible substrates of RFID tags.

摘要： An image processing method comprising at least one of: recording an image on a thermoreversible recording medium by heating the thermoreversible recording medium by application of a laser beam thereon, the image being formed of a plurality of laser beam lines; and erasing an image from a thermoreversible recording medium by heating the thermoreversible recording medium by application of a laser beam, the image being formed of a plurality of laser beam lines, wherein during laser scanning where the laser beams are swept over the medium in parallel at a predetermined distance, the laser beams are sequentially applied in alternating directions, some part of the laser scanning involves a period where laser application is discontinued, and the period where laser application is discontinued involves no laser beam application from a first laser scanning end point to a second laser scanning point, the first laser scanning end point corresponding to the end point of laser scanning started at a first laser scanning starting point, and wherein the thermo-reveisible recording medium offers temperature-dependent reversible changes in transparency or color tone.

摘要： An image processing method including at least one of recording an image onto a thermoreversible recording medium in which transparency or color tone reversibly changes depending upon temperature, by applying a laser beam with the use of a CO 2 laser device so as to heat the thermoreversible recording medium, and erasing an image recorded on the thermoreversible recording medium, by heating the thermoreversible recording medium, wherein the intensity distribution of the laser beam applied in the image recording step satisfies the relationship represented by Expression 1, 1.59 I 1 / I 2 ≤ 2.00
where I 1 denotes an irradiation intensity of the applied laser beam in a central position of the applied laser beam, and I 2 denotes an irradiation intensity of the applied laser beam on a plane corresponding to 80% of the total irradiation energy of the applied laser beam.
