Description
Technical field
The present invention relates to a kind of printing ink, more specifically to a kind of printing ink special for photographic paper identification printing.
Background technology
Colour paper, be a kind of sensitive materials of coating silver emulsion on the paper substrate that has applied Polyvinyl chloride resin, has easy sensitization that general sensitive materials often has, vulnerable to pollution, easily produces the special photographic chemistry performance such as photographic fog.
Printing-ink is the material that is used to form graph text information in printing process, plays very important effect in printing process, directly determines contrast, color, sharpness of printed matter epigraph etc.The characteristic of printing-ink comprises printing ink fineness, transparency, sticking power, mobility, viscosity, viscosity etc., and the printability of printing ink mainly contains viscosity, tack, thixotropy, drying property etc.
Along with the development of printing technology, the kind of printing-ink is also constantly increasing, and according to mode of printing, can be divided into:
1, letterpress inks: in order to a class printing ink of Printing books and periodicals, newspaper, picture album, document, account book etc.The principal character of letterpress is that the printing surface inking partly protrudes from non-inking part.
2, planographic ink: be applicable to a lithographic class printing ink.Lithographic space of a whole page each several part is basically in a plane, figure line place oleophylic, and blank space is hydrophilic, utilizes the principle that profit repels each other to be printed, therefore planographic ink must possess water repelling property.Difference by typography can be divided into single-sheet offset printing ink, web offset printing ink, flat flexographic ink, waterless offset ink, tin printing ink, plastic printing ink, lithographic printing ink, collotype printing ink, offset printing light resin printing ink, offset rotary ink etc.
3, gravure printing ink: a class printing ink of applicable intaglio printing.Be recessed into during printing in the figure of space of a whole page line part inking, the China ink of non-figure line part is wiped or scraping, then printed.Photogravure ink, plate engraving ink etc. are arranged.
4, stencil printing ink: by the mesh of the forme class printing ink that surface printed of undertaking the printing of of biting.The hole printing ink is divided into again stencil printing ink, silk-screen plate printing ink etc.
5, specialty printing printing ink: the printing ink of special purpose is arranged, as foam ink, magnetic ink, fluorescent ink, electrically conductive ink, heat fixed type ink, quick-setting ink, gloss ink, toughness printing ink, aqueous vapor are solidified printing ink, UV curable ink, anti-forgery ink, glass ink, marking ink, anti-forgery ink, color shifting ink, luminescent ink, aluminum foil ink, spraying printing ink, duplicated the special-purpose printing-inks such as printing ink, spices printing ink.
And printing ink special for photographic paper identification printing belongs to specialty printing printing ink.
Printing-ink is mixed and is adjusted refining to form by 4 parts.
1, pigment.Solids component in printing ink is the substance that show color of printing ink.The performance of the performances such as the saturation ratio of ink colors, tinting strength, transparency and pigment has close relationship.
2, low-melting ink vehicle.The liquid composition of printing ink, be the carrier of pigment, plays a part to link pigment.The printing performances such as the degree of mobilization of printing ink, viscosity, drying property, physical strength all depend on low-melting ink vehicle, are the bases of ink quality.
3, stopping composition.The main packing action that rises, make printing ink increase concentration, have diffusion and lubricating effect concurrently, stopping composition commonly used comprises cornflour, magnesium oxide, calcium carbonate, barium carbonate, aluminum oxide, wax fat and Vaseline etc., both can reduce amount of pigment, reduce costs, again the character of capable of regulating oil China ink, as rare thick, mobility etc., handiness simultaneously that also improved formulating of recipe.
4, auxiliary agent.In order to improve the printability of printing ink, the various materials that add as the performance such as viscosity, tackiness, drying property, kind is quite extensive, and each class printing ink has its distinctive auxiliary agent, and it is much mutually general also having.Siccative, anti-(prevent) siccative, antioxidant, antiskinning agent, anti-peptizing agent arranged usually, remove (punching) light dose, remove stick, thinner, prevent (gluing) dirty dose, (preventing) infusion, softening agent, spices, sanitas, stablizer, tensio-active agent, dispersion agent, wetting agent, thickening material, slip compound, slipproofing agent, anti-pinhole agent, nonscum compound, UV light absorber, photostabilizer etc. disappear.
The colour paper identification printing belongs to the monochromatic intaglio printing of roll type, but makes a big difference with common roll type intaglio printing:
1, the base material difference of printing.The base material of common intaglio printing is all generally paper, and paper surface has certain roughness, and good adsorbed state and wicking action are arranged, and printing-ink is easy to adhere on paper.Colour paper is different, it is to have applied the layer of polyethylene resin coating on paper substrate, its surface smoothness is high, wettability and tack are poor, be difficult for accepting the infiltration of printing ink, Polyvinyl chloride resin itself has antioxygen in addition, and these all can have influence on the drying after printing, affects the bonding of China ink layer.
2, printing ink can not affect the photosensitive property of colour paper, comprises keeping property.Colour paper has all characteristics of sensitive materials, need lucifuge, various components in printing ink used can not have to the performance of colour paper any change, while can not be carried out surface treatment in advance to colour paper before printing, as corona treatment, flame treating, chemical solution are processed, organic solvent is processed, tensio-active agent is processed and be coated with processing etc.
3, because colour paper all needs to have post-processed, so the acidic substance in post-production liquid medicine, the high-temperature technology in treating processes can not exert an influence to the color of printing ink, bonding force etc., and printing ink can not produce and pollute post-production liquid medicine.
Therefore, printing ink special for photographic paper identification printing and other printing-inks have very large difference, can't substitute with the printing-ink on present market.
