摘要： A dye transfer ribbon (1) comprises a supporting substrate (2) and a relatively thick dye layer (3) consisting of a dye dispersed within a dye binder. A modulated scanning laser beam (7) heats selected pixel regions of the ribbon (1) and causes dye to diffuse from these regions to the receiver sheet (5) and print a number of pixels thereon which build up to form an image (sublimation transfer is also possible). In order to allow the ribbon (1) to be reused, and so not waste the ribbon or the untransferred dye, the ribbon (1) is passed between a pair of heated rollers (8a, 8b) to cause dye in the dye layer (3) to diffuse to an even density, so that the regions depleted of dye during the print process are replenished, and so that the ribbon may be reused. Instead of the replenishment dye coming from the body of the ribbon (1), it may come from a separate source. The ribbon (1) may be replaced by a dye sheet or a pad, such as a roller, and provision may be made for colour printing.

摘要： A scanning laser beam (5) heats selected regions of a dye donor ribbon (4) to transfer dye to a receiver sheet (2) to form an image therein. The beam scan rate and delay time between the start of successive pulses is set so that adjacent heated pixel regions overlap and so that a significant amount of residual heat from a first printed pixel is still present when heat is applied to the next adjacent pixel. The use of this residual heat improves the printing efficiency. An elliptical beam may have its major axis in the scan direction to facilitate overlap. Printing may be effected to a non-square grid with more information (and a repetition of information) a set number of times in the scan direction. The power applied to a pixel may be adjusted depending on the darkness of previous adjacent printed pixels.
摘要翻译：扫描激光束（5）加热染料供体带（4）的选定区域以将染料转移到接收片（2）以在其中形成图像。设置连续脉冲开始之间的光束扫描速率和延迟时间，使得相邻的加热像素区域重叠，并且当向下一个相邻像素施加热时，来自第一印刷像素的大量剩余热量仍然存在。使用这种残留热量可以提高打印效率。椭圆形光束可以在扫描方向上具有其长轴以便于重叠。打印可以在扫描方向上具有更多信息（和信息重复）设定次数的非方格网格。可以根据先前相邻印刷像素的暗度来调整施加到像素的功率。

摘要： The use of materials having a moisture absorption of less than 1%, in particular the use of a dye diffusion thermal transfer receiver sheet, for 35 mm format transparencies prevents the fogging of the projected image which can occur with conventional transparencies based on a cellulose triacetate/gelatin/silver halide combination and which is caused by moisture from this combination condensing out at the interface with the protective mount.

摘要： In a thermal transfer printing apparatus, a receiver sheet or ribbon (2) and a donor sheet or ribbon (3) are held adjacent one another and printing is effected by heating the donor (3) so that dye passes to the receiver (2). Heating of the donor (3) is effected through the receiver (2), preferably by a laser beam (6). Preferably, the receiver (2) is held stationary on a convex surface of a support plate (10). No flat field optics are then required when using a scanning laser beam, and the donor ribbon (3) may be easily replaced or wound on to allow for colour printing from differently coloured dye donor regions, without needing to re-register the receiver (2) each time.

摘要： In light-induced thermal printing of images on to transparent receiver sheets, e.g. for 35mm transparencies, an improvement in sensitivity (i.e. the Optical Density of the final image that can be achieved for a given energy input) is improved by providing the dye sheet with a reflective layer positioned such that laser light projected through the receiver sheet and not absorbed on the first pass through the dye sheet is reflected back so as to be absorbed on a second pass. Alternatively, a sensitivity improvement may be achieved by positioning the transparent receiver sheet against a surface having a reflective layer.
摘要翻译：将图像的光感应热印刷到透明接收片上，例如对于35mm透明胶片，提高灵敏度（即，对于给定的能量输入可以实现的最终图像的光密度）通过为染料片提供反射层而改进，所述反射层定位成使得激光通过接收片投射，而不是在通过染料片的第一次通过时吸收被反射回以在第二次通过时被吸收。或者，可以通过将透明接收片放置在具有反射层的表面上来实现灵敏度提高。

摘要： An image printed onto a receiver sheet (6) by dye sublimation transfer printing is fixed in the receiver sheet (6) by a flash of infrared rich light from e.g. xenon or krypton flash tubes (2). The receiver sheet (6) is mounted on a glass support plate (4). A reflector (3) directs the light towards the receiver sheet (6), and a reflector (5) reflects back infrared light which has passed through the receiver sheet (6). Instead of or in addition to using infrared light, a flash of ultraviolet and/or any other invisible electromagnetic radiation could be used.

摘要： A scanning laser beam (7) heats selected pixel regions of a dye donor ribbon (3) to cause dye to transfer to a receiver ribbon (2) to form an image therein. The beam (7) heats each selected pixel region for less than about 15 microseconds. This increases the efficiency of the printing, as the short heating times produce heated regions of about 2 microns in the dye transfer direction, which is all that is required in order to transfer dye from the dye layer (3a) to the dye receiver layer (2a).
摘要翻译：扫描激光束（7）加热染料供体色带（3）的选定像素区域以使染料转移到接收器色带（2）以在其中形成图像。光束（7）将每个选定的像素区域加热小于约15微秒。这增加了印刷的效率，因为短的加热时间在染料转移方向上产生约2微米的加热区域，这就是为了将染料从染料层（3a）转移到染料接收层图2a）。
