Water marked paper (often referring to watermark paper) is a kind of ancient and effective traditional anti-counterfeiting technology, and watermark is a water mark method that is easy to identification with the naked eye most, uses till today after coming out certainly always, and develops with the continuous development of correlation technique.Water marked paper is in the forming process of paper web, utilizes the web forming technology, and just having interweaved at page forms when also having certain moisture, uses the watermark hydraulic pressure seal paper of engraving lines, makes the displacement of l Water Paper page or leaf portion of tissue form various marks or pattern.Because the watermark picture and text are different with the thickness of blank space, make density and the light transmission difference thereof of paper, like this, the back side demonstrates Clear ﹠ Transparent watermark picture and text under the irradiation of normal optical.The paper watermark will not produce strong deformation because of look, light, variation of temperature after being shaped as paper, it does not separate with the page one integrated mass; Be easy to large-scale production, and can under equal production process equipment condition, keep the consistent relatively of front and back product; Again because of the watermark recovery level summarize terse, profile is soft and moist, complex process, be difficult to accurately copy, so the difficulty that copies is very big, extremely strong security feature is arranged.
The watermark lines mostly is customization, and the special watermark that represents a company is in order to ensure that the ticket that the said firm prints can not copied or forge.And paper plant be in order to ensure its specific user, can be again in order to not make other special objects paper yet, and this measure has promoted the manufacturing cost of paper and has contained the false proof factor of cost.For example, the banknote that first cover has special watermark has been issued in Stockholm in 1666.
The description of paper watermark has following several according to the difference of sorting technique: dividing from purposes has artistic watermark and anti-counterfei waterprint, and the former is mainly used in invitation card, greeting card, lampshade etc., and the latter is mainly used in various certificates, security, certificate, tax reciept, banknote etc.
Itself divide from the watermark making, according to the difference of technology or product, watermark can be divided into fixedly mixed watermark of the watermark of full version, watermark continuously, fixedly watermark, full version again.Fixedly the typography of watermark and technical difficulty are bigger, are used for banknote, passport more.Fixedly watermark is fixed on the certain position at main position of stocks such as bank note, passport, certificate usually, and will cooperate accurately with macroscopic printing figure message or other false proof measures usually.At the watermark window position Mao Zedong, workman, the fixedly watermark of peasant's head portrait are arranged respectively as China 100 yuan, 50 yuan, 10 yuans of version in 1999.Distance, position between every group of watermark of semifixed watermark are fixed, and each group is arranged on paper continuously, so claim continuous watermark, are used for special-purpose paper more.The watermark of fixed position is not distributed in the whole space of a whole page of paper, so claim the watermark of full version yet.5 yuan of coin of China print with full version ancient money water marked paper.
As one of a kind of traditional false proof mode, watermark is one of requisite false proof mode in various countries' bank-note paper or the senior cheque paper always.Its antifalse effect can only be embodied by visual form, therefore is referred to as " one dimension watermark ".
Along with progress and the expanding economy of science and technology, marketable securities, certificate, classified document etc. have been subjected to lawless person's madness and have forged, and have seriously upset normal financial order and civil order.As one of tradition and effective false proof mode, watermark is one of requisite false proof mode in various countries' bank-note paper or the senior cheque paper always.Because its antifalse effect can only be embodied by visual form, therefore reduced its false proof effect.Particularly, the fake producer has reached the purpose of rudimentary fraud by technological means such as printings, and the popular recognition capability that does not possess specialty.These give the fake producer with opportunity.
