Seal prevents bogus to should consider from two respects: Be seal cannot forge a gender; 2 be Yin Wen can differentiate a gender. Solution can forge a problem to need to begin from the respect such as the seal material, craft that make, equipment that make anything but (strengthen management to make special subject additionally discuss) ; And of Yin Wen can differentiate a problem to want from stamp-pad ink, pattern recognition, build the respect such as seal record library to try hard.
Laser technology and computer technology are forward position of contemporary science and technology. The birth of this two old techniques, cause the revolution of print immediately. Laser replaced letter of hundreds of years to presswork according to the platoon. Letter composing is in China earth is almost disappeared. Suffer those who stimulate illumination platoon to inspire, this two old techniques are introduced very quickly also seal is made and prevent bogus domain.
Computer composing raised seal craft water to make the same score greatly with the speed that make, and the method that laser sculpture replaces plate making tool set, handiwork and cutting tool photoelectricity successfully to dog, cause the widespread attention of concerned branch and connoisseur.
The monochromatic sex of laser, tall brightness, directional good good point, be applied extensively at material treatment, like laser heat treatment, cut, solder, mark is engraved etc. In these circumstances, laser is regarded as attend function of aeriform " of " cutting tool in material, make material produces fused, vaporization, fashion all sorts of process. Advanced industry country all includes advanced production technology laser beam machining and popularize energetically. Laser carven principle is: Stimulate beam of light to be transmitted via optical orgnaization be in with focusing material apparently, the surges point of action of beam of light material of high energy density is rapid vaporization, form indentation place. Benefit drives the switch that laser head moves and controls laser according to the requirement with console of computer control X-y, the picture news after classics software is handled already pressed some kind of means to be put in the computer, should read from inside the computer by order when taking news, laser head along scanning contrail from left scan back and forth line by line to right from the top down. Scan every time when a "1" is nodded, your laser open, when scanning is nodded to a "0" , your laser closes. We know, the computer stores news has by the binary system, this as it happens and laser switch conform to of two kinds of condition.
In transforming current and popular seal composing software the special laser that can be used at waiting for composition by workbench of laser, scanning, computer to carve equipment slightly, go. Because this is planted,the laser in equipment has YAG and CO2 commonly two kinds. YAG is used at metallic sign to engrave, achieve ideal deepness not easily. Cannot use Yu Yinzhang to carve here. And CO2 laser is appropriate the sculpture of metalloid material. With respect to seal character, mat of rubber-plastic, ox horn, organic glass, marble, jade, Chu Mo, lumber all can engrave make, achieve better deepness and precision. CO2 laser power chooses 1-20 tile. Quarter make 3-5 of a renown chapter minute, official seal 15-30 minute. Current, the laser of equipment gets together spot is less than 0.1mm. Mechanical resolution 0.025mm repeats 0.1mm of fixed position precision. Engrave the seal that make to accord with the occupation standard of seal completely.
