Definitions

  • Printing inks generally include one or more vehicles and one or more colorants as principal components.
  • the printing ink vehicles must meet a number of performance requirements that include both requirements related to the particular printing process being employed, such as suitable consistency and tack for sharp, clean images, suitable length to avoid fly or mist, or proper drying characteristics, and requirements related to the printed image, such as gloss, chemical resistance, durability or color.
  • the ink vehicles include one or more materials such as vegetable oils or fatty acids, resins, and polymers that contribute to the end product properties, and may include other components such as organic solvents, water, rheology modifiers, and so on, that may affect body, tack, or drying characteristics.
  • lithographic printing use is made of plates having hydrophobic image areas and hydrophilic non-image areas.
  • the plate cylinder first comes in contact with dampening rollers that transfer an aqueous fountain formulation to the hydrophilic non-image areas of the plate.
  • dampening rollers that transfer an aqueous fountain formulation to the hydrophilic non-image areas of the plate.
  • Typical damping processes utilizing a water or aqueous fountain solution are described in U.S. Pat. Nos. 3,877,372; 4,278,467; and 4,854,969.
  • water forms a film on the hydrophilic areas (the non-image areas) of the printing plate, but contracts into tiny droplets on the oleophilic areas (the image areas) of the plate.
  • the dampened plate contacts an inking roller to apply an the oil based ink.
  • the inked roller containing the oil based ink When the inked roller containing the oil based ink is passed over the damped plate, it is unable to ink the areas covered by the water film (the non-image areas), but will emulsify the droplets on the water repellant areas (the image areas), causing such area to accept the ink.
  • the inked plate is then contacted with the substrate to be printed in order to transfer the desired image to that substrate.
  • offset lithography the inked image on the plate does not directly print onto the paper or other substrate, but is first "offset” onto a rubber blanket, and then transferred from the blanket onto the paper substrate.
  • the lithographic printing process has always presented unique challenges to ink formulators, since such process utilizes a planographic printing plate in which the image and non-image areas are in the same plane on the image carrier, and two fluids are concurrently utilized to insure that ink adheres only to the image area, and not to the non-image area. Establishing and maintaining a correct ink/water balance during the printing process is critical, and requires a high level of skill.
  • lithographic printing inks A large variety of lithographic printing inks are known.
  • the requisite properties for such lithographic inks include sufficient adherence to the image areas, non- adherence to the non-image areas, and, in addition to these obviously fundamental properties, suitable levels of properties which relate to flow, interfacial behavior, and drying.
  • the greasy ink is required to maintain an adequate balance between the ink-water interfacial tension and the surface tensions of both phases, because otherwise there will occur gradual enlargement or, conversely, disappearance of the image areas, emulsification of the ink, and a phenomenon of scumming during the printing of thousands or tens of thousands of copies with the alternate feeding of a greasy ink and water which is repeated for each copy.
  • the lithographic ink generally contains colorant and a vehicle, and may include one or more additives such as, for example, plasticizers, stabilizers, driers, thickeners, dispersants, and fillers.
  • a lithographic printing process using UV/EB curable inks is not as robust as the process using conventional sheetfed and heat set lithographic inks.
  • materials which will enhance the viscosity and emulsified ink characteristics of UV/EB inks closer to that of a heatset or sheetfed ink are useful for that purpose.
  • a gel-like additive such as a gel containing cellulose acetate butyrate or polyvinyl butyral or related materials is useful for that purpose.
  • the use of a relatively small amount of the gel-like additive in the ink can produce a significant change in the ink's press performance, rheology and/or emulsified ink viscosity. It can also be used in conventional sheetfed and heat set lithographic inks.
  • Cellulose acetate butyrate resins are known as dispersing materials for many ink and coating applications, particularly for color concentrates.
  • Cellulose ester resins are also used in the furniture industry in base coat formulations as they provide good holdout and adhere well to many surfaces.
  • CAB resins are used with urea formaldehyde resins, polyurethanes and acrylics as seal coatings.
  • Paper coatings derived from alcohol soluble solutions of CAB and urea formaldehyde resins yield films that exhibit scuff resistance, flexibility and ultraviolet light stabilization.
  • Cellulose ester resins are noted to be useful in printing inks. Eastman Chemicals, technical data sheet, CAB-553-0.4 and CAP-482-0.5.
  • a gel-like additive is used as a component in lithographic inks to provide improved lithographic performance as reflected in the change in emulsion capacity (%EC) and frequently also by the lithographic performance index (LPI).

  • the inks of the invention generally have a LPI of at least 0.5, preferably at least 0.6, and most preferably at least 0.8.
  • the LPI is not greater than 1.
  • the LPI is dependent on the hydroxyl content of the hydroxyl-containing organic resin used to make the gel and the higher the content, the higher the LPI and the ink viscosity. Also, the presence of the gel also decreases the misting of the ink, which allows for wider operating conditions on a printing press.

Abstract

Lorsqu'on l'utilise dans les encres lithographiques, un gel contenant une résine organique dure à base d'hydroxyle et un (méth)acrylate alcoxylé améliore les performances lithographiques. Avec ces encres, on obtient une plus grande capacité d'émulsion, un meilleur transfert d'impression et une voltige réduite. En général, l'encre lithographique contient un colorant, un véhicule, le gel précité, et, le cas échéant, d'autres additifs classiques.
