Definitions

  • HSWOS heatset web offset
  • Pantone high-light or special color
  • Higher quality sheet offset litho printing normally has at least six or more printing units in series.
  • the offset printing process especially in perfecting presses, has the capability of simultaneously printing both sides of a paper web at speeds as high as 3000 fpm (ft./min.).
  • the "offset printing process” gets its name from the fact that "images” are formed on lithography plates then transferred (offset) to a rubberized printing blanket stretched around a cylinder.
  • the inked part of the lithography plate that is also stretched around a cylinder forms the image that gets transferred to the offset blanket then in turn to the paper.
  • the non-image areas of the lithographic plate are hydrophilic and are protected against ink adherence by fountain solution (water, gum arabic, surfactant, and acid).
  • fountain solution water, gum arabic, surfactant, and acid
  • the image is offset from the top lithography plate to the paper by the offset blanket.
  • an identical unit "perfects" or contacts the moving paper web from the bottom thus printing both sides simultaneously.
  • ink is transferred to the web or wet-trapped onto the paper either to previous inked image areas or to non-image areas.
  • This is called wet trap in that non-image areas of the offset blanket transfer a very thin layer of fountain solution to the paper along with ink in the image areas.
  • the ink forming the image on the paper from the previous printing station (unit) has the possibility to re-split or "back trap” from the paper to the next offset printing blanket and so on. This phenomenon is known as back trap mottle (BTM).
  • Back trap mottle is an undesired result from offset printing because a non-uniform print image is created.
  • Printers desire to reduce or eliminate back trap mottle so uniform ink densities result whether they are "solids”, “quarter tones”, “half-tone” or “ 3 /4-tones” or any ink density range in between or transition points within an image.
  • the invention relates to a paper and paperboard material comprising a paper or paperboard substrate, a basecoat layer on at least one surface of substrate and topcoat on a surface of the basecoat, said topcoat comprising one or more pigments dispersed in one or more binders and said basecoat comprising low density thermoplastic particles low density thermoplastic particles dispersed in one or more binders.
  • This invention also relates to a method of preparing the material of this invention comprising: applying a basecoat composition comprising low density thermoplastic particles dispersed in one or more binders to a paper or paperboard substrate and applying a topcoat composition comprising one or more pigments dispersed in one or more binders over the basecoat.
  • This invention provides one or more advantages that are believed to result from inclusion of the low density thermoplastic particles in the basecoat. These advantages include reduced 2 nd cyan mottle, enhanced sheet gloss and print gloss and/or enhanced Sheffield and Parker Print smoothness as compared to a similar material having the same characteristics except for the presence of low density thermoplastic particles in the basecoat.

  • Scanner mottle is determined using the following procedure: Representative samples are selected from pigment coated paper or paperboard printed under controlled conditions typical of commercial offset litho production with the cyan process ink at a reflection density of 1.35 ⁇ 0.05. A 100 percent solid cyan print reflective image is digitally scanned and transformed through a neural network model to produce a print mottle index number between zero (perfectly uniform ink lay with no mottle) to ten (visually noticeable, objectionable and likely rejectable because of print mottle, a random non-uniformity in the visual reflective density or color of the printed area). Data from this 2 nd Cyan scanner mottle system can be correlated to subjective visual perception (using the zero-to-ten guideline) or can be transformed into equivalent mottle values as measured with a Tobias mottle tester from Tobias Associates using the following equation:
