热升华打印技术及其应用

The Technique and Application of Thermal Dye-sublimation Printing

随着数码照相机逐渐普及,对彩色数码照片打印的需求日益增多,对照片的质量要求越来越高,这为热升华打印转印技术的应用提供了发展空间。热升华技术就是利用升华的原理,使固相彩色颜料经热记录头加热直接升华为气相,进而转印到介质上生成影像。打印出的图像层次分明而丰富,输出效果细腻精美,比喷墨打印机和激光打印机的图像效果好,画质可与银盐照片比美。

With the popularity of digital cameras, the demands on color digital photoprinting are increasing, the people＇s requirements for the quality of photograph are higher and higher, this have provided developing space for application of Thermal dye-sublimation printing technique. The dye-sublimation technology is made use of the principle of sublimation, and heat primary color pigment to sublimate it into gas by THERMAL PRINT HEAD, and then, transfer on media to generate images. The image＇s gradations of color printed out are clear and rich, exporting effect is exquisite and better than the image of the ink printer and the laser printer, and photo quality can match with the silver sensitive photo.
