Abstract
The invention relates to colorized transparent anti-counterfeit watermark paper and a manufacturing method thereof. The colorized transparent anti-counterfeit watermark paper comprises body paper; a colorized thin film is arranged in the body paper; the using amount of the colorized thin film is 0.1 to 10 percent of the area of the paper; and the colorized thin film is colorized polyvinyl acetate (PVA) or a gelatin thin film, and comprises 0.01 to 0.3weight percent of water-soluble dye. The colorized thin film is processed into a desired shape as required; the colorized thin film is added into paper pulp through an orientated releasing device so that the colorized thin film is directionally distributed on a certain part of the paper or uniformly distributed in the paper. The colorized transparent anti-counterfeit watermark paper manufactured by the method has high light resistance, acid resistance, alkali resistance, oxidant resistance, reductant resistance, organic solvent resistance, heat resistance and the like, so the material can be well applicable to anti-counterfeit and encrypting technical field of securities, tickets, currency paper and the like.
Description
Technical field
The present invention relates to a kind of Colorized transparent anti-counterfeit watermark paper and preparation method thereof, the technical field such as this anti-counterfeiting technology can be applicable to false proof, encryption, also can be used for the field of papermaking such as security, bill, bank-note paper.
Background technology
Water marked paper (often referring to swim printing paper) is a kind of ancient and effective traditional anti-counterfeiting technology, and watermark is a water mark method that is easy to the naked eye identification most, uses till today always, and develop with the development of correlation technique after certainly coming out.Water marked paper is in the forming process of paper web, utilizes web forming technology, at page, has just interweaved while forming also with certain moisture, uses the watermark hydraulic pressure printing paper face of engraving lines, makes the displacement of l Water Paper page portion of tissue form various marks or pattern.Different from the thickness of blank space due to watermark picture and text, make the density of paper and light transmission thereof different, thereby the back side is under the irradiation of normal optical, demonstrates Clear & Transparent watermark picture and text.Paper watermark, after being shaped as paper, will not produce strong deformation because of the variation of look, light, temperature, and it is not separated with page one integrated mass; Be easy to large-scale production, and can under equal production process equipment condition, keep the relatively consistent of front and back product; Again because of watermark recovery level summarize terse, profile is soft and moist, complex process, be difficult to accurately copy, so the difficulty copying is very big, has extremely strong security feature.
Watermark lines mostly is customization, and the special watermark representing a company, in order to ensure that the ticket that the said firm prints can not copied or forge.And paper plant is in order to ensure its specific user, can be again in order to manufacture other special object paper usings yet, this measure has promoted the manufacturing cost of paper and has contained the false proof factor of cost.For example, the banknote of first set with special watermark issued in Stockholm in 1666.
The description of paper watermark, according to the difference of sorting technique, has following several: from purposes, divide and have artistic watermark and anti-counterfei waterprint, 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.
From watermark making, itself divide, according to the difference of technique or product, watermark can be divided into again fixedly mixed watermark of the watermark of full version, watermark continuously, fixedly watermark, full version.Fixedly the typography of watermark and technical difficulty are larger, are used for banknote, passport.Fixedly watermark is fixed on the certain position at main position of the stocks such as bank note, passport, certificate conventionally, and conventionally will coordinate accurately with macroscopic printing figure message or other false proof measures.As 100 of China in 1999 version yuan, 50 yuan, 10 yuans, at watermark window position, there are respectively Mao Zedong, workman, the fixedly watermark of peasant's head portrait.Distance, position between every group of watermark of semifixed watermark are fixed, and each organizes continuous arrangement on paper, so claim continuous watermark, are used for special-purpose paper.The watermark of fixed position is not distributed in the whole space of a whole page of paper, therefore claim the watermark of full version yet.Full version ancient money water marked paper printing for 5 yuan of coin of China.
The method of making water marked paper is a lot, as water marked paper, paper that moulding machine is made are carved water marked paper, chemical water printing paper etc.
1. mold water marked paper
The paper of the bar code with embossment shape that application moulding machine is made etc.In paper-making process, the watermark picture and text forme designing is in advance installed on silk screen, or is suppressed and form by printing cylinder.Because picture and text height is different, make paper pulp form the different corresponding density of thickness.After one-tenth paper, the density of Yin Tuwen place paper pulp is different, and its light transmittance is variant, therefore when printing opacity is observed, can show intrinsic picture and text, these picture and text are referred to as watermark.
2. paper is carved water marked paper
" paper carving " anti-counterfeiting technology, can be used for the false proof printing of stamp." paper carving " technology is that engraving is combined with digital watermark, and, on very thin stamp dedicated paper, the pattern forming with the simple indenture of special means carve is observed under light, and pattern also can present a kind of effect of watermark." paper carving " false proof level of technology is high, easily detects identification.Can be widely used in the anti-counterfeit printing of stamp and other marketable securities.
3. chemical water printing paper
Chemical water printing paper is that chemical substance is printed on to watermark version made on paper.For example, by the method for printing, the homogeneous mixture of thermosetting resin and curing agent is printed onto on page, solvent wherein starts volatilization, before solvent is removed not yet completely, applying glue solution on double exposure, two-layer print film is carried out slaking in contact process, and printing figure message becomes the opaque film of a kind of hard gradually.Adopt heating means to promote thermosetting resin cured, printing figure message becomes opaque watermark quickly, and the watermark solvent resistance of formation is good.
Above digital watermark has various shortcomings: as the uneven distribution of fiber makes paper regional area fibre weight less, cause paper local strength on the low side, and watermark recovery readability is not high.
Summary of the invention
