On The Ink Composition And The Relationship With The Printing Quality
Print Ink Is Pigment , Link material, Filler Uniform mixture of ingredients such as colloidal slurry composition. As a viscous fluid ink, because of its variety of different properties have also been poor <, that is thick with thin divided between strong and weak viscosity, fast drying and slow drying of the other and so the situation. Therefore, the correct understanding and knowledge of the composition of ink in the ink in the role, for accurate adjustment of ink properties to meet the conditions for making a variety of printing, and improve product quality printing Measuring Tools Are of great significance.
First, the role of pigment in the ink
Pigment including Pigment And Dye . Used in printing ink materials are usually colored pigment, it also uses a number of dyes, which are very fine particles of colored material. Pigments generally do not dissolve in water, not soluble binders, most of the solution into the suspension, and dyes are generally soluble compound link. Pigment ink has a great impact on the performance of the role of the relative density of ink, transparency, heat resistance, light resistance and chemical resistance, have with the paint. The role of pigment in the ink is obvious, its color determines the hue of ink; its size determines the amount of ink concentration; its use to the ink to a certain degree of consistency and other physical properties; its use under the influence to some extent drying of ink, Oxidation Polymer-based ink drying was particularly prominent. In addition, the ink is in the durability of various aspects of the decision by the pigment. Therefore, because ink variety, use different pigments is also equipped with the difference, which requires the printing shall be based on product use, technology use compatible ink characteristics, such as high-speed Multi-color printing press Print Package Products should be selected light, fast-curing, and wear properties of ink to ensure print quality.
2, links the role of material in the ink
Link material is a certain viscosity, the fluid, its role is multifaceted. As a pigment carrier, play the Powder Shape of the pigment mixture of solid particles such as link up, and to eventually phase adhesion of paint products on the attached print. Link materials and decisions that affect the speed of the solid ink, the drying rate and drying same type, but also to the ink to a certain degree of gloss, abrasion resistance, yellowing resistance and impact resistance and other physical properties, and to a large extent determine the viscosity of the ink, viscosity, yield value and mobility, so, high-quality ink from high quality materials link. If the link does not apply to material preparation or production process, after the printing ink is not only a lack of bright, shiny and good color, but also lead to paste version, rub dirty, through print, pull hair and no less than ink on paper chains such as the quality of fault, to the normal printing bring some obstacles. Therefore, the link is expected to ink a great influence on the quality factor.
3, filling the role of material in the ink
Filler is evenly dispersed in the link has a better compound, white solid material is fine powder. Filler compound in the link after mixing and Grind When later turned into paste, some transparent, some are opaque. Commonly used as filler with hydrogen Alumina , Sulfuric acid Potassium, magnesium and Calcium carbonate And so on. Filler in the ink in the ink on the one hand can play adjust consistency, viscosity, viscosity, mobility and yield value of such ink, on the other hand can play the role of adjusting the concentration of ink, that is, when the ink concentration of big hue deep cases, after adding filler to dilute the role of energy. Filler in the ink though play a supporting role in the side, but its performance has many of the requirements is consistent with the paint, mainly in order to oxidative polymerization drying ink dry in the impact it has played the same role.
IV Additives Role in the ink
Printing operator, the ink Printability Well, one can put to use to open lid, of course, is trouble in the most convenient. However, due to the printing environment temperature and humidity differences, printing material properties and different printing conditions, such as the PH value of water content in paper and printer speed, trapping methods different, and despite the ink variety is diverse, but each ink used in paints, fillers, binders, and the ratio is almost constant and often can not meet the requirements of various conditions of printability. Therefore, to improve work efficiency and quality of the printing point of view, according to a great variety of printing conditions, the inks used in the appropriate add some additives to ensure the normal printing is useful.
