Cl. 161-6 2 Claims ABSTRACT OF THE DISCLOSURE This invention comprises an artboard composed of interfitting matrices of oppositely tapering elements having their bases in one face of the artboard and extending to a sharp point or ridge at substantially the other face, the color of the upper face of this paper material normally beirig white, and the color of the lower matrix material being normally black but may be of any other color, or may be transparent, so that erasure of the white surface of the art-board to different depths in various areas will produce screen tones of different shades of color or degrees of transparency in the corresponding areas of the artboard in accordance with the design desired.
This invention relates to a new type of art paper, which may be called screenboard, since it is adapted primarily for producing various screen-tone compositions by removal of the superposed layers of the paper by erasure to the desired screen-tone layers in selected areas, the layers at successive depths in the face of the paper varying in screen-tone from the surface in a predetermined order bygradual changes through a predetermined range of desired screen-tones.
The main object of this invention is to produce a screenboard art paper composed of paper material having an internally pigmented structure such that the screen-tone and/or color of the successively exposed layers of the paper by erasure of its surface to succeedingly increasing depths will gradually change through a predetermined range of tone and/or color in selected areas of a surface as may be required for a desired composition.
A further object is to produce a screenboard paper of the above type in which the pigmented portion of the structure is black, the remaining portion being either white or transparent, as may be desired, for producing different screen-tones or screens in selected areas of the paper.
A further specific object is to produce such a screenboard paper wherein the black portion extends through the thickness of the paper material from points and/or thin lines arranged in any pattern just under the solid white or transparent surface layer, in diverging cones or ridges to a solid black surface layer on the opposite side of the paper, for use in producing any desired screentones in selected areas on either side of the paper which may have guides or illustrations normally inscribed thereon for indicating said areas, by rubbing off the paper to the cofresponding depths in said areas to produce said desired screen-tones.
Other and more specific objects will appear in the following detailed description of this invention as illustrated in the accompanying drawings, wherein:
r FIGURE 1 is a magnified perspective view of a piece of the novel screenboard art paper with varying screentone areas produced by erasure thereof to correspondingly varying depths in its various portions.
' FIGURE 2 is a perspective view of a sheet of screenboard paper of this type with a magnified detail perspective view of a corner of the black portion of the paper structure.
FIGURES 3 and 4 are similar illustrations of modifications in the black portion of the structure.
The present screenboard may be used primarily by artists and craftsmen in the advertising field.
It provides an artist with a board material on which he can produce an original half-tone illustration, with a full range of tones, ranging from a solid black or a Solid white through all shades of gray to a full white or a full black respectively, depending on which side of the board he selects to work from. The half tones may consist of any dot or line pattern suitable for good printing reproductions. By substituting a transparent material for the white portion of the board, half tone transparencies may be obtained by working from the black side of the board.
Screenboard may be furnished in practical sizes and suitable thicknesses such as are now in general use for art work. It can also be furnished in various screen sizes such as 65 line for newspaper and circular work as well as in the finer screen sizes necessary for magazine illustration.
Internally the screenboard will consist of thousands of very small pyramids 10 or pointed ridges 12 of black and white material extending from opposite surfaces of the board, and intermeshing in a uniform pattern with each other to form a solid sheet. This sheet will thus appear as white on one side 14 and black on the other side 16. The number of pyramids per square inch will be governed by the screen size. Example: 65 line size will contain 65 X65 or 4225 pyramids per square inch.
The material used in making the intermeshed layers in the board may be any paper material suitable for pressing, casting, filling or rolling for production manufacturing. Many such materials may be found to be entirely satisfactory for the artist, which he may use in cutting, pasting, inking, whiting and general handling of this board.
As an artist works on this medium to produce a halftone drawing, he may use a knife, stylus or abrasive tool to scratch away the surface of the board. When working on white side, the more the surface is removed, the larger the black dots or thicker the lines will become, thereby producing a darker shade of gray. By controlling the depth to which the board is removed the artist will gain the desired shade necessary in selected areas of the board to represent any and all portions of a given subject. Conversely, by working on the reverse or black side of the board an opposite effect will be attained in a parallel or cross line pattern Where the thickness of the lines or size of dots are reduced as deeper portions of the surface is removed.
The perspective view in FIG. 1 of a board of the type illustrated in FIG. 2 is shown after its white surface has been rubbed off to varying depths in selected areas forming a contour surface which is darkest at its low areas such as 18 and 20 and lightest at its high areas such as 22 where it has not been rubbed off very much.
The straight ridge forms 12 of black material shown in FIG. 3 are used to produce the straight line pattern screen-tone, and the wavy line pattern screen-tone is produced with a board construction having wavy ridge forms 2 as shown in FIG. 4.
The forms illustrated are used to produce the most common type of screen-tones. However, many other forms of pyramid and line patterns may be made in a similar manner to produce other desired screen or line tones.
The present screenboard may be used in many other ways besides making original screen-tone illustrations.
(1) It provides a means for an artist to prepare a half-tone copy with a full range in size of dots from full white to solid black;
(2) It provides a method of producing a half-tone plate at considerably less cost than conventional methods;
(3) It provides a method whereby an artist can furnish many different effects for reproduction which are now prepared by camera work or extensive art work;
(4) It furnishes a completely new media for printing reproduction;
(5) It makes it possible for the artist in preparing copy, to see exactly how his Work will appear as a halftone reproduction;
(6) It is conducive to use with other artist supplies such as lettering, numbering call outs and such art supply helps as are in general use;
(7) It provides a method whereby a blind person can visually a picture by the touch method, where the depth of depressions may be interpreted as correspondingly dark tone areas in accordance with their depth variations as may be read by touch sensing of the surface of the paper board;
(8) It provides a faster more direct method of producing offset printing plates, etc.; and
(9) It provides a means of producing a variety of colortones by erasure; e.g., green colortones between blue and yellow; orange colortones between yellow and red; purple colortones between red and blue; and many other predetermined mixed colortones and shadings in any desirable ranges.
What is claimed is:
1. A sheet of paper material comprising a layer composed of a series of miniature pyramidal forms of black paper material having their bases joined edge-to-edge across one entire face of said sheet, and having a height substantially equal to the thickness of said sheet, and
a layer composed of a complementary form of white paper material filling the volume between said pyramidal forms within the thickness of said sheet and forming the opposite face of said sheet, whereby different tone screens may be made by removing the white surface of said paper to different depths.
2. A sheet of paper material comprising a layer composed of a series of miniature pyramidal forms of transparent material having their bases joined edge-to-edge across one entire face of said sheet, and having a height substantially equal to the thickness of said sheet, and
a layer composed of a complementary form of opaque paper material filling the volume between said p'yramidal forms within the thickness of said sheet and forming the opposite face of said sheet, whereby different tone screens may be made by removing the opaque surface of said paper to different depths.
