總結(jié)具有高效蓋印效果的技術(shù)要點1 光敏印章的原理The principle of a photosensitive seal 光敏技術(shù)指的是利用光敏材料的感光特性進行印章制作的方法。專用的光敏材料是一種超微泡材料，其表面的微孔孔徑非常小，平均孔徑小于30微米。本身具有儲油滲油及光閃熔特性。光敏材料在受到強光照射的時候，可以吸收光能并轉(zhuǎn)換成熱能，顏色越暗吸收的能量越多。曝光時，光敏材料表面見光部分瞬間吸收大量的光能后，溫度迅速上升并達到熔點，閃光結(jié)束后，表面熔體的溫度迅速降低，形成一定厚度和強度的薄膜，這層薄膜同時起到封孔閉孔的作用，并隔絕印油的滲透。這就是光敏章成像的原理。利用光敏材料的這一特性，用激光打印機將章稿打印在具有透光特性的硫酸紙或激光膠片上，將其覆蓋在光敏材料上后放在曝光機內(nèi)曝光，由于章稿本身具有黑度不能透光，因而章稿覆蓋的光敏材料沒有受到光照仍然可以儲油滲油，而其他部分則由于受到光照發(fā)生凝固不能滲油，從而實現(xiàn)了印章的制作。由于激光打印機的打印精度在1200dpi以上，加之光敏材料本身的超微孔結(jié)構(gòu)，因此，光敏印章的精度比采用激光雕刻的印章或其它技術(shù)方式制作的印章的蓋印精度高出許多，是目前印章制作精度最高的一種印章。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)首先使用排版軟件將印章排版，目前國內(nèi)常用的印章排版軟件有很多種。由于光敏印章的高清晰性，目前很多光敏印章排版軟件都具有編排指紋防偽、邊框防偽細(xì)條紋等功能，用戶可以這些利用隨機生成的防偽紋，排版出防偽印章。(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)激光打印機打印章稿。印章排版好以后，需利用激光打印機將章稿打印在硫酸紙或透明膠片上。此時，要求激光打印稿具有足夠的黑度及均勻度。否則將嚴(yán)重影響光敏章的制作質(zhì)量。礦用風(fēng)機部分用戶采用二手激光機或噴墨打印機打印章稿，看似節(jié)省了打印成本，其實是揀了芝麻丟了西瓜。(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)光敏印章機曝光：將打印了章稿的硫酸紙或膠片覆蓋上透明曝光膜及光敏印章墊。三者之間的順序及朝向依次為章稿背面向曝光光源，乳化液泵站章稿打印面貼曝光膜，曝光膜貼印章墊，三者依次平穩(wěn)緊密接觸，中間嚴(yán)禁有間隙式皺折。三者壓緊后曝光既可。(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 光敏印章機技術(shù)研究與分析。3 photosensitive seal machine technology research and analysis. 光敏印章機的技術(shù)性能對光敏印章的制作質(zhì)量起著至關(guān)重要的作用。光敏印章機主要包含光敏燈管電源及光敏印墊機械壓緊裝置兩大部分。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. 光敏機的電源部分包含電容的充放電部分及光敏燈管的觸發(fā)電路部分，通常采用倍壓充電的方式，充電電壓在400v-600v時可以觸發(fā)光敏燈管導(dǎo)通曝光。充電電路中充電電容一般采用450v，1ooouf電解電容串并聯(lián)構(gòu)成。選擇高品質(zhì)、高穩(wěn)定性的電解電容可以提高光敏機整機的穩(wěn)定性和可靠性。目前水性油墨光敏印墊的種類繁多，不同印墊要求的曝光能量也千差萬別。曝光能量不足會造成印章邊界模糊，不清晰，而曝光過度又會造成章面吸油性變差，影響蓋章質(zhì)量。一般要求光敏印章機單根燈管曝光能量最大能達到600焦耳以上，雙管光敏機的能量最大能達到1200焦耳以上。同時，根據(jù)印墊種類的不同，要求光敏機的曝光能量能夠根據(jù)印墊的不同要求平滑可調(diào)。目前國內(nèi)光敏機多采用雙光敏燈管設(shè)計，由于每根管子的導(dǎo)通性不可能完全一樣，在進行電路設(shè)計時，應(yīng)該采用兩組獨立的電容充放回路。這對提高光敏燈管的壽命，提高整機的穩(wěn)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
