Definitions

  • This invention relatesto gravure printing and a portion of a composed page of type matter, in more particularly to typographicalcharacters and the form, of at positive transparency, prepared character bearing"ei'mentsfor iis i'n'the photoin accordance with the invention; 7 graphic m 1 4 Figure 7 is aplanyiewpfe portion of aprintep .f i
  • strokes defining the configuration of the respective typographical characters are thus etched as a network of tiny cells or depressions, with a criss-cross pattern of upstanding ridges separating and isolating the respective cells.
  • This formation is illustrated in Figure 1 wherein the ridges 22 which extend completely across the strokes of the character divide the strokes into the sharp, square-cornered cells 28.
  • the present invention affords for the first time practical methods and means for producing type matter of good quality by gravure.
  • the process of the invention commences with the preparation by drawing (which term is used herein to comprehend drawing, painting and other forms of manual preparation such as composite mock-up) of a master typographical character such as is shown in Figures 3 and 4.
  • One method of preparing such a character is illustrated in Figure 3 and comprises, as a first step, photographically enlarging a conventional gravure screen to provide an opaque negative photographic print 30 of the desired screen pattern.
  • the particular screen pattern illustrated is known as a crossline screen and comprises two sets of equally spaced parallel black lines 32 at right angles to each other on a white background. There are thus formed between the black lines 32 of the screen pattern square, sharp-cornered white spaces 34-.
  • any other form of gravure screen may be used, but preferably the screen should be of the same type or pattern as that used in the preparation of the cylinder for printing pictorial and display matter, so that the etching procedures for both the type matter and the display matter may be equalized in timing, acid concentration,
  • the screens most frequently used in gravure Work have of the order of 120 to 175 lines per inch, with the width of the lines 32 equal to one-half or one-third the width of the inter-line spaces 34. In the particular screen illustrated the ratio of line width to inter-line space is 1:2.
  • the screen is enlarged by photographing to such scale as will render manual drawing of the type character most convenient.
  • the actual scale used may be varied according to individual taste and will frequently depend upon the intricacy of the strokes and serifs or" the particular type face, but a lateral enlargement of the order of 40 times has been found satisfactory.
  • the artist blacks out as by inking, a portion of ing in shape and size to the strokes which define the typographical character to be reproduced. Then the artist whites in a marginal area 40 around the outline of the strokes of the character, this area suitably being of a width of the order of that of the black lines 32 of the screen pattern. This leaves visible within such White marginal outline 40 the pattern of black lines 32 and white spaces 34 of the screen. As apparent, the white margin 40 has the appearance of merging with those w ite spaces 34 of the mate reproduction.
  • the negative character outline 38 while the screen pattern outline 40 is provided.
  • the artist may prepare the positive character shown in Figure 4 directly Without first preparing the negative shown in Figure 3. In doing so, he may either use an enlarged positive photographic a print having groundand White in black out the character defining area 38. he may draw up the character including the screen pattern entirely by hand.
  • the character of Figure 4 is then photographed, this time opaque screen lines 32 but transparent marginal spaces 34'.
  • This transparency may be cut to form a circular plaque 42 for mounting in a matrix generally indicated at 44.
  • the matrix 44 will be recognized as of the form described in Patent No. 2,231,899 to H. R. Freund and used in conventional high-speed photocomposing metchines such as that shown in Patent No. 2,391,021 to E. G. Klingenberg et a1.
  • the matrix may be of the type disclosed in Patent 6 No. 1,543,527 to R. J.
  • each of the characters of the type matter etched on the cylinder has within its outline the depressions 2i) corresponding to the screen spaces 4, and upstanding ridges 22 corresponding to the lines 32 of the screen pattern.
  • a channel or gutter 48 merging with the depressions 2D ridges 22 to tinuous channel 48 after the action of the doctor blade are left filled with ink, which, sreading evenly from such continuous channel 46 around the outline of each character, Will form an impression upon the paper having straight, sharp and even outline defining edges 38, such as shown in Figure 8.
  • Figure 9 An alternative form of character is illustrated in Figure 9. This is formed according to any of the methods described above, but has a singlene screen instead of a cross-line screenthat is, it has only one set of spaced parallel lines 48, whereby elongated, inter-line spaces 59 are formed across the strokes of the characters and merge with the marginal outline 48 formed around the character according to the invention.
  • the lines 48 terminate short of the character defining outline 38, so that the embodiment of Figure 9 affords the advantageous results described above.
  • Figure 9 accordingly illustrates one of the alternative forms of gravure screen which may be utilized in the practice of the present invention.
  • a type character-bearing element for use in the photographic reproduction of type matter by the gravure process, said element bearing, against an opaque background, a typographical character translucent except for an internal pat tern of spaced, opaque lines extending substantially throughout the entirety oi said character but terminating short of the outline thereof to leave a substantially continuous translucent margin extending around said outline.
  • a type character-"nearing matrix for use in the photographic reproduction of type matter for printing by the gravure process, said matrix having an opening through the body thereof, a plaque mounted in said opening having an opaque background and bearing a typographical character translucent except for an internal pattern of spaced, opaque lines extending substantially throughout actor but terminating short of the outline thereof to leave a substantially continuous translucent margin extending around said outline.
  • type characterbearing element bearing in an opaque background, a typographical character translucent except for an lines extending tirety of internal pattern of spaced, opaque substantially throughout the ensaid character but terminating short chine of the type wherein type character-bearing matrices are serially and individually exposed to a photosensitive surface to form a photographic record of composed type matter, the
  • matrix of duction of a type character-bean the photographic reproby the for use in type matter for printing gravure process said matrix having an opening through the body thereof, a plaque mounted in said opening having an opaque background and bearing a typographical character translucent except for an internal pattern of spaced, opaque lines extending substantially throughout the entirety of said character of the outline thereof to but terminating short leave a substantially continuous translucent margin extending around said outline.
