Definitions

  • the object of this invention is to provide a process of reproducing high grade wood and other natural grain effects on metallic or other bases, which will more faithfully portray the tonal effects of the original wood pattern.
  • a more specific object is to provide a process for faithfully reproducing butt or burl walnut and the like, that is to say, woods which have more or less under-toning between the full tones, half tones, etc. of grain line coloring and the base or ground color.
  • the process is unique in that I use, in addition to the usual grain transfer as from an intaglio plate, an additional under-toning transfer, preferably from a second intaglio plate, prepared as will be hereinafter shown.
  • the pattern to be reproduced, as on a metal panel is first photographed in negative, then a positive plate or film is made photographically, and from this a carbon resist.
  • the carbon resist is then used to form an etched printing plate; the darker portions of the pattern, the grain lines, being reproduced on the plate in the form of cavities of varying depth, making what is known as an intaglio plate.
  • the cavities may be broken up into smaller cavities by the use of a screen in one of the photographic steps. covered with pigment of the desired color and theplate is then scraped clean, except for the cavities, and thereafter the design is transferred, preferably by means of a transfer roll, onto the panel to be grained.
  • intaglio plate produced as just described, and applying the design thereof over a suitable ground color, on say a metal panel, and suitably working the transferred design to blend the more faint grain coloring with the ground color, a comparatively faithful reproduction of origlnal woods may be effected: In the process, the full tones, half tones, etc. are brought out by reason of the fact that certain of the re- Afterward, the plate is.
  • the under-toning plate may be produced, for example, by two methods, substantially similar, but each having variations to suit the subject to be reproduced.
  • the under-toning plate may be made, starting wlth an actual photograph of that portion of the subject which shows the undertonings, or it may be produced, starting with a hand traced pattern of that portion of the subject having the under-tonings.
  • I preferably first lay a suitable transparent sheet of material, such as celluloid, over the original subject or pattern, and trace in a general pattern of the darker grain areas, particularly where the under-tonings appear to be showing past the darker grain lines.
  • the tracing may be by means of an air brush, the color of any nature being thus sprayed onto the sheet of celluloid, making a rough equivalent of a positive photographic film of the pattern or parts thereof.
  • This celluloid sheet is now placed in contact with the usual carbon resist sheet and the sheet is exposed to light through the film.
  • the carbon resist will thus be light treated, except where the design appears.
  • the resist is also exposed to light through a suitable screen, such as the Rembrandt screen having opaque blocks separated by transparent thin lines. This results in breaking up the design into squares.
  • the resist is then used to etch the plate either fiat or on a roll. Preferably, only a light etching is used, since the undertoning color is always faint, and it is therefore desirable to transfer only a small amount of color, corresponding to the under-toning, onto the panel or like base to be grained.
  • under-toning transfer After the under-toning transfer has been applied to the ground color, as through the intermediacy of a gum transfer roll, other under-toning colors may be worked 1 by hand, using the original pattern as a master copy, and using the under-toning transfer as a guide to properly place the additional under-toning colors.
  • the process of obtaining an under-toning plate may be varied, in that, instead of making a tracing, as by hand, of the original design, I may first take a photograph, preferably by a brief exposure, and possibly blocking but those ortions of the origina design w erethe an er-tonin are not apparent to the eye. From this p otograph, a positive image late or film is made, then a carbon resist; a terwards, exposed through a screen, as taught by the Henry patent, and the resist is used to make the under-toning plate.
  • Fig. 1 an enlarged cross sectional view of the grained panel
  • Fig. 2 is an enlarged diagrammatic plan view of a portion of such grained panel, made by using a hand traced design of the full tones of the pattern as a first step in producing the under-toning plate
  • Fig. 3 is a similar plan view showing (again diagrammatically) the result of using an actual photograph as a first step in producing the under-toning plate.
  • l designates the panel body, 2 the coating of ground color, and 3 the pig- -ment applied by the first or under-toning transfer.
  • This pigment appears as disconnected blocks, due to breaking up the design, as by the screen above mentioned.
  • the first transfer may or may not be covered with a locking coat of lacquer or varnish, such as 4, this depending largely on whether or not such coating is warranted by the use which the panel will ultimately serve.
  • the final transfer, appearing as heavier disconnected blocks 5, is now printed over the first transfer, and this is then covered with a coating of protecting lacquer or varnish 6; to be afterward rubbed down and polished to secure the desired finish.
  • the disconnected blocks of pigment, both at 3 and 5 are of varying depth and cross sectional area. This is the natural result of etching the plate through a resist such as previously described. It will be further noted that the blocks at 5 are partially out of registration with the blocks 3, allowin the under-tone color at 3 to be seen alongsi e the full grain coloring 5, as well as through the more or less transparent colorin "at 5.
  • Fig. 3 illustrates, in principle, the manner in which under-tone patches 3a would appear with relation to the grain line patches 5a where both plates are made substantially in the same manner, i. e. starting with a photograph and where both transfers are printed in true registration.
  • Fig. 3 illustrates, in principle, the manner in which under-tone patches 3a would appear with relation to the grain line patches 5a where both plates are made substantially in the same manner, i. e. starting with a photograph and where both transfers are printed in true registration.
  • actual non-registration exists in certain zones, as would naturally result from separately working the transfers, as with a brush, to tone down the sharp outlines.
  • the process of simulating natural grain pattern effects on a base having a hard surface comprising, applying a ground color coating to such surface, preparing a plate or roll, by hand copying a general design from the original pattern corresponding in general to the darker design portions of such pattern, using the copy in the photographic chain of steps necessary to etch the plate or roll, preparing another plate or roll photographically and by etching, but using a photograph taken from the actual pattern design to be reproduced to distinctly copy the darker grain effects, and using said plate or rolls, one after the other, to effect successive imprints over the ground color.
