Definitions

  • This invention relates to a method of reproduction of type characters, and more particularly, relates to a method of reproducing a graphic Character or profile identical to that of the original design by deforming to a predetermned degree the original design.
  • the method of the present invention for producing type characters by building up the profile of conventional letters or indicia comprises the step of reshaping only a part of the standard type Character, particularly by changing the Straight edges adjacent the corners of the letter into ntersecting concave edges.
  • the present invention distinguished from the conception in Ormay firstly, because the appearance of the type Character is not changed, secondly because no Shading is added which would alter the appearance, and thirdly because only those erodable portions adjacent the intersections at the corners of the type characters are reformed to concave edges.
  • the Character is further Complicated by the fact that not all portions of a design profile undergo the same degree of erosion during photographic reproduction.
  • Another object of this invention is to provide, -in a photocomposition procedure, a novel process for reproducing eXact reduced duplicates of an original Character or figure design.
  • FIG. 1 is a partial veiw On a blown up Scale of an Patented Jan. 31, 1967 original design of a Character to be photographed and reduced;
  • FIG. 2 shows a view of a conventional photograph of the FIG. l design
  • FIGS. 3 and 4 Show respective views of deformations made to characters to be duplicated in a predetermined manner according to this invention
  • FIG. 5 shows a view of an original graphic profile to be Copied
  • FIG. 6 shows the same profile as FIG. 5 but reversely deformed according to the present invention.
  • FIG. 7 shows a View of the results of photographic reproduction of the reversely deformed Character of FIG. 6.
  • FIG. 1 a view of a portion of a Character 11 having corners 13 which, if photographically reproduced to the Size of type in a conventional manner, will result in a degraded Character 15 having a profile as shown in FIG. 2. It is seen that the Character 15 has rounded corners 17, and that the Character 15 is thus an eroded copy of the original Character 11.
  • FIGS. 3 and 4 show how, according to the present invention, this erosion or degradation is compensated by Selective reverse deformation.
  • an original Character portion 19 has a profile Similar to that of FIG. 2 terminating in original squared-Otf ends 21, indicated by the dashed lines.
  • the original ends 21 are built up in a reverse deforming manner SO that each corner of the ends 21 is fiared out or is extended by concave curved lines 23 in transverse and longitudinal directions to more acutely angled points 25 located distinctly beyond the geometrical confines of the original end 21.
  • the points 25 are connected by a concave curved line 27 having its innermost portion distinctly outside the geometrical confines of the original end 21.
  • An inverted V Character portion 29 shown in FIG. 4 has an original interior acute angle corner 31 and an original eXterior acute angle corner 33.
  • the original corners 31 and 33 are indicated in dashed lines. If reproduced in a conventional manner, the corners 31 and 33 will become rounded as indicated by the respective curved lines 35 and 37. This roundness obviously degrades the sharpness and clarity of the Character 29.
  • the interior acute corner 31 is reversely deformed, so that it will reproduce to its original shape, by means of Slghtly concave cuts 39 and 41 converging to a point 43 located inwardly of the original corner 31. That portion of the original Character between the dashed lines forming corner 31 and the cuts 39 and 41 is thus removed.
  • the eXterior acute angle corner 33 is reversely deformed by building up its profile between concave lines 45 and 47 extending Outwardly of the Corner 33 and converging to a point 49.
  • an original Character 51 is to be photographically reproduced and reduced exactly.
  • the character 51 has protruding corners at 53, 55, 57, 59, 61, 63 and 65 which, if the Original Character 51 were photographically reproduced and reduced without reverse deformation, it would be eroded or rounded off thus resulting in a degraded reproduction thereof.
  • the Character 51 is built up at each of its corners 53-65 with respective shaded portions 53a 65a of greater Curvature and acuteness to form a reshaped Character 51a.
  • the corrected design is then photographed With any suitable equipment so that the image is reduced in height 80 times. Exposure may be made for seconds With an f/22 aperture, The negative thus obtained may be Kodak Super Mince obtained With an Esta-r support.
  • the reduced negative is developed in a Kodalith developing bath, agitating for 30 seconds, and then by letting it rest for about 2.5 minutes.
  • the reduced negative is then removed from the Washing bath and is introduced to a Kodak fiXing bath, then removed and dried.
  • a copy of the reduced negative is made by contact of the negative on a bromograph (contact printer) With a point light source.
  • the negative is placed on the glass of the bromograph, With the sensitive Surface of Ferrani Vega 208 D paper turned toward the negative film and exposed for 10 seconds.
  • a positive photograph is developed by placing said 2 08 D paper in a Gevaert Metinol development bath for about 2.5 minutes, and then fixed in a Kodak bath and dried.
  • the Gevaert Develop autopositive paper and the Ferrani Vega 208 D paper are eXamples of silver chloride and Silver chloride-Silver bromide mixed print papers and may be used for the desired high Contrast of the print. There are available on the market, in Europe, Japan and the U.S.A., many types of Silver chloride and Silver bromide print papers for high contrast hotography.
