Definitions

  • This invention relates to the art of printing, and pertains more particularly to improvements in methods of preparing a plate for color printing and in the construction of the finished plate.
  • the principal purpose of the invention is to provide a simple and practical method and eflicient apparatus for producing a colored print in which the various colors exhibit the full tone values, pleasing tonal shadingsand other technical effects heretofore characteristic of hand work.
  • My invention may be suitably used with either intaglio or letter press printing processes, and is adapted to produce either water color of varnish color prints, it being understood that the finished prints are produced by utilizing the improved plates prepared 'in accordance with my methods and thence following the usual processes of printing from such plates upon suitable paper.
  • the color prints are characterizedby the absence of sharply defined dots or prominent lines (which are characteristic of prints produced by the so-called three or four color processes through the utilization of halftone plates), by gradual color shading, or by faint outlines, wherever such effects are desired.
  • the resulting pr'mt simulates very closely the full color tones and technical shadings of a hand colored picture, and so far as I am aware such a result has 'not heretofore been attained by mechanical printing processes.
  • Fig. 1 is a plan view of the improved plate
  • the medium 5 may be a viscous solution, for
  • Fig. 2 is an enlarged section on line 2-2 of Fig. 1 showing one mode of preparingthe printing surface
  • Fig. 3 is a similar view illustrating a modified treatment of the printing'surface.
  • I may employ a base 4 of, metal, wood, fibre board or other suitable sheet material which, when treated in accordance with my invention, is adapted to provide a printing plate.
  • the surface which is to be treated may be flat and smooth, rough and irregular, or regularly uneven in the manner of an engraved plate or electrotype; for the ultimate printing surface may consist of the hardened coating medium which is applied upon one face of the base material or plate (either as a complete covering or at selected areas) and which will fill any depressions or irregularities in said face if so desired.
  • I may partially or completely fill selected valleys or hollows or coat other portions of the plate with my coating medium,
  • the coating medium consists essentially of a resinous substance which will adhere in the form of a hardened coating to the surface of the base plate.
  • varnish lacquer or shellac which may be flowed, sprayed, wiped, brushed, or moulded upon the base plate and which dries hard upon its surface upon evaporation of its solvent; in another aspect (Fig. 3) the medium 6 may be applied in a dry state, for example in the form of powdered resin, and fused upon the base plate by heating it with a blow torch or in any other suitable manner which results in the melting and adhesion of the dry particles to each other and rto theplate surface.
  • a blow torch or in any other suitable manner which results in the melting and adhesion of the dry particles to each other and rto theplate surface.
  • primary coats of the medium may be applied before such final treatment, and it will be understood that each coating of the viscous shellac or varnish is allowed to dry and harden before the next coat or further local applications are applied. If portions of such coats are to be removed, the material may be wiped or brushed away before hardening, if desired; or the hardened coat may be scraped or ground off locally or treated with a suitable solvent to furnish the valleys which are desired.
  • the brushing or wriping operations may be performed before the coating has completely hardened or while the surface of the hard coating is temporarily softened by the application of a suitable solvent, and that the use of a stiff brush or a piece of coarse textile fabric, or even the finger, produces definite but irregular lines or rough surface areas when the coating re-hardens after brushing or wiping in this manner.
  • These irregular variations in the printing surface enhance rather than impair the' apperance of the resulting print for they further assist in imparting the desired brush-tone values which are intended to represent the hand work of the artist.
  • the slopes 9 of the hills or raised portions thus created may be abrupt or gradual according to the effect desired, and the resulting print will exhibit color intensities and tonal shadings corresponding to the level variations and the degree of slope of the graduated printing surface.
  • the water colors or varnish inks which are applied to the printing surface of the improved plate and impressed upon the paper in accordance with usual printing practice, exhibit the characteristic and effective features of hand paintings, particularly the full tone values and soft shadings of actual brush work.
  • a further characteristic of hand work is particularly noticeable when the coating medium is applied in a dry state and fused as aforesaid.
  • the heat applied to the shellac powder is not too intense or is applied only a short time, the powder does not completely melt and run together, but adheres to the base material or plate in the form of finely divided granules, as shown at 10, Fig. 3.
  • a printed impression of such a surface (suitably colored in printing) closely simulates hand pastel or crayon effects; and the print is therefore peculiarly attractive and unique.
  • the heat treatment of the dry medium may be regulated to emphasize or subdue this characteristic feature, either locally or over the entire printing surface. .It is also apparent that the crayon effect may be associated with the brush-tone values produced by the completely fused dry medium or by complemental 'coatings of the viscous shellac, as indicatedat 11.
  • my toning medium may be applied either in a dry or viscous state as a coating upon a base pla.'.e or printing plate of any suitable material, and it is apparent that the printing plate may be flat or curved according to the type of press employed for .printing.
  • the particular design which is to be printed I may be initially outlined upon the plate, in
  • the coating may be applied to the outlined areas of the plate; or, after applying one or two coats of the medium, the surplus ground of the hardened primary coat may be routed out or tooled away in the usual manner, after the desired image is impressed of proofed thereon. Thereafter, the brush tone values may be provided by building up or removing local areas of the printing surface; and it is apparent that portions of the coating medium may be completely removed to expose the surface of the base plate, if desired.
  • a process of preparing a printing plate which consists in coating the surface of the plate at predetermined areas with a viscous, hard-drying medium to produce variations in the level of the printing surface, whereby the resulting print exhibits tonal values corresponding to said level variations.
  • a process of preparing a printing plate which consists of applying and adhering coating to the surface of the plate, and producing variations in the thickness of said coating, whereby the resulting print exhibits tonal values corresponding to said variations in thickness.
  • a process of preparing a printing plate for color printing which consists in applying a coating of adhering medium to the surface of the plate, and building up said coating by additional local applications of said medium to produce variations in the level of the printing surface, whereby the resulting print exhibits gradations in color intensity corresponding to said level variations.
  • a process of preparing a printing plate for color printing which consists in applying a coating of an adhering medium to the surface of the plate, and removing portions of said coating to produce variations in the level of the printing surface, whereby the resulting print exhibits gradations in color intensity corresponding to said level variations.
  • a process of preparing a printing plate for color printing which consists in coating the surface of the plate with a viscous, hard-drying medium, and building up portions of said coating by local applications of the mediums to produce hills and valleys in the printing surface, whereby the resulting print exhibits tonal values corresponding in shading and intensity to said hills and valleys.
  • a process of preparing a printing plate for color printing which consists in coating the surface of the plate with a viscous, hard-drying medium, removing portions of the coating while soft, and building up other portions of the hardened coating by local applications of the me-' dium, to produce hills and valleys in the printing surface, whereby the resulting print exhibits tonal values corresponding in shading and intensity to said hills and valleys.
  • a process of preparing a printing plate for. color printing which consists in fusing a granular coating medium upon the surface of the plate, and producing variations in the thickness of the fused coating, whereby the resulting print exhibits tonal values corresponding to said variations in thickness.
  • a process of preparing a printing plate which consists in applying a granular, resinous medium to the surface of the plate, fusing the medium to the plate by the application of directed heat effective with varying intensity at different portions of the medium, thereby to cause variations in the degree of fusion of the particles, whereby the resulting print exhibits tonal effects corresponding to said variations.
  • a process of preparing a printing plate for color printing which consists in applying an adhering coating to selected areas of the printing surface of the plate, and varying the surface level of the coating by brushing it while the coating is soft, so that a print taken from such uneven surfaces exhibits tonal values correresponding to said level variations.
  • a process of preparing a printing plate for color printing which consists in applying an adhering coating to selected areas of the printing surface of the plate, and varying the surface level of the coating by wiping it while the coating is soft, so that a print taken from such uneven surfaces exhibits tonal values corresponding to-said level variations.
  • a process of preparing a printing plate for color printing which consists in app y a granular coating medium to selected areas of the printing surface of the plate, and fusing said granular mediums to the plate by applying heat with varying intensity at predetermined portions of said medium, thereby to vary the character of the printing surface so that the resulting print exhibits tonaleffects corresponding to said variations in the printing sm'face.
  • a printing plate for color printing comprising a base member and local coatings of a hardened resinous material applied to selected areas of the hue member, certain of said coatings having a thickness differing appreciably from that of other coatings and the surface of certain of the individual coatings having irregular depressions therein, said coatings constituting the printing surface of the plate and being deformable, and removable from the base member.
