总结具有高效盖印效果的技术要点1 光敏印章的原理The principle of a photosensitive seal 光敏技术指的是利用光敏材料的感光特性进行印章制作的方法。专用的光敏材料是一种超微泡材料，其表面的微孔孔径非常小，平均孔径小于30微米。本身具有储油渗油及光闪熔特性。光敏材料在受到强光照射的时候，可以吸收光能并转换成热能，颜色越暗吸收的能量越多。曝光时，光敏材料表面见光部分瞬间吸收大量的光能后，温度迅速上升并达到熔点，闪光结束后，表面熔体的温度迅速降低，形成一定厚度和强度的薄膜，这层薄膜同时起到封孔闭孔的作用，并隔绝印油的渗透。这就是光敏章成像的原理。利用光敏材料的这一特性，用激光打印机将章稿打印在具有透光特性的硫酸纸或激光胶片上，将其覆盖在光敏材料上后放在曝光机内曝光，由于章稿本身具有黑度不能透光，因而章稿覆盖的光敏材料没有受到光照仍然可以储油渗油，而其他部分则由于受到光照发生凝固不能渗油，从而实现了印章的制作。由于激光打印机的打印精度在1200dpi以上，加之光敏材料本身的超微孔结构，因此，光敏印章的精度比采用激光雕刻的印章或其它技术方式制作的印章的盖印精度高出许多，是目前印章制作精度最高的一种印章。Photosensitive technology refers to the use of photosensitive photosensitive material features of seal engraving method. Dedicated photosensitive material is a kind of ultramicro bubble, the surface of the micro hole diameter is very small, the average pore diameter is less than 30 microns. Itself has a flash light oil reservoir permeability and nature. Photosensitive materials under strong light irradiation, can absorb the light energy is converted into heat energy, the darker color absorbs more energy. Exposure, photosensitive material surface after see light some instantly absorbs a great deal of light energy, temperature rise and melting point is reached quickly, after flashing, surface melt temperature decrease rapidly, forming a certain thickness and strength of the film, the film at the same time have the effect of hole sealing hole closed, and block the penetration of user. This chapter is photosensitive imaging principle. Using the characteristic of the photosensitive materials, using laser printers will draft chapter LiuSuanZhi or laser film on light characteristics, its coverage on the photosensitive material is placed within the exposure machine after exposure, because the draft chapter itself has black can not pervious to light, and therefore draft chapter photosensitive materials are not covered by light can still reserves, oil leakage, and the other part is due to light solidification can not oil leakage occurs, so as to realize the production of the seals. Due to laser printers print accuracy above 1200 dpi, and ultramicro structure of photosensitive material itself, as a result, the precision of the photosensitive seal than laser engraving seals or other technical method to make the sealed with the seal of much higher precision, is by far the highest precision of seal engraving seals. (1)首先使用排版软件将印章排版，目前国内常用的印章排版软件有很多种。由于光敏印章的高清晰性，目前很多光敏印章排版软件都具有编排指纹防伪、边框防伪细条纹等功能，用户可以这些利用随机生成的防伪纹，排版出防伪印章。(1) the first to use typesetting typesetting software will seal, seal typesetting software commonly used at home and abroad, there are many. Due to high-definition photosensitive seal, at present many photosensitive seal typesetting software arrangement are fingerprint security, border security pinstripe, and other functions, the user can use a randomly generated these anti-fake grain, typesetting the anti-fake seal. (2)激光打印机打印章稿。印章排版好以后，需利用激光打印机将章稿打印在硫酸纸或透明胶片上。此时，要求激光打印稿具有足够的黑度及均匀度。否则将严重影响光敏章的制作质量。矿用风机部分用户采用二手激光机或喷墨打印机打印章稿，看似节省了打印成本，其实是拣了芝麻丢了西瓜。(2) laser printer seal. Seal after typesetting, to draft chapter using laser printer to print on LiuSuanZhi or transparent film. At this point, the required laser typescript have enough black degree and evenness. Otherwise will seriously affect the quality of photosensitive chapter production. Some users use seal draft used laser or inkjet printer, seemingly save printing costs, is actually collected sesame lost watermelon. (3)光敏印章机曝光：将打印了章稿的硫酸纸或胶片覆盖上透明曝光膜及光敏印章垫。三者之间的顺序及朝向依次为章稿背面向曝光光源，乳化液泵站章稿打印面贴曝光膜，曝光膜贴印章垫，三者依次平稳紧密接触，中间严禁有间隙式皱折。三者压紧后曝光既可。(3) exposure: photosensitive seal machine will print the draft chapter LiuSuanZhi or film covered with transparent film exposure and photosensitive seal cushion. Between order and toward the manuscript back to the exposure light source, followed by chapter chapter draft print stickers exposure film, exposure film stick a stamp pad, three in turn smooth close contact, it is forbidden to have clearance between buckling. The three pressure after exposure can be. 3 光敏印章机技术研究与分析。3 photosensitive seal machine technology research and analysis. 光敏印章机的技术性能对光敏印章的制作质量起着至关重要的作用。光敏印章机主要包含光敏灯管电源及光敏印垫机械压紧装置两大部分。Photosensitive seal machines technical performance of photosensitive seal quality plays a vital role. Photosensitive seal machine is mainly contain photosensitive lamp power supply and photosensitive seal cushion mechanical clamping device of two parts. 光敏机的电源部分包含电容的充放电部分及光敏灯管的触发电路部分，通常采用倍压充电的方式，充电电压在400v-600v时可以触发光敏灯管导通曝光。充电电路中充电电容一般采用450v，1ooouf电解电容串并联构成。选择高品质、高稳定性的电解电容可以提高光敏机整机的稳定性和可靠性。目前水性油墨光敏印垫的种类繁多，不同印垫要求的曝光能量也千差万别。曝光能量不足会造成印章边界模糊，不清晰，而曝光过度又会造成章面吸油性变差，影响盖章质量。一般要求光敏印章机单根灯管曝光能量最大能达到600焦耳以上，双管光敏机的能量最大能达到1200焦耳以上。同时，根据印垫种类的不同，要求光敏机的曝光能量能够根据印垫的不同要求平滑可调。目前国内光敏机多采用双光敏灯管设计，由于每根管子的导通性不可能完全一样，在进行电路设计时，应该采用两组独立的电容充放回路。这对提高光敏灯管的寿命，提高整机的稳定性是非常重要的。Photosensitive machine power supply section contains capacitance charge-discharge parts and photosensitive lamp trigger circuit, voltage charge way, usually takes times when charging voltage 400 v - 600 - v can trigger photoconductive tube conduction exposure. Charging capacitance in the charging circuit generally use 450 v, 1 ooouf electrolytic capacitor series parallel form. Choose high quality, high stability of the electrolytic capacitor can improve the machine stability and reliability of the machine. At present there are many types of photosensitive seal cushion, different printing pad required exposure energy also differ in thousands ways. Exposure energy deficiency can lead to seal the border fuzzy, not clear, and excessive exposure can result in chapter surface oil absorption, affect the quality of seal. General requirements photosensitive seal machine single bulb exposure energy maximum can reach more than 600 joules, double tube photosensitive machine biggest can reach more than 1200 joules of energy. At the same time, according to the type of the pad printing for photosensitive machine exposure energy can adjustable according to the different requirements of pad printing is smooth. At present domestic photosensitive machine adopts double photosensitive lamp design, because of every tube guide connectivity cannot be exactly the same, in the circuit design, should use two separate groups of capacitor charge circuit. This to improve life of the photosensitive tubes, it is very
