' This invention relates toimprovements in the printing art, and more particularly to means and method for producing better and *more perfect printing.
The invention is applicable to type having relatively large, bold printing characters,
such as letters, numerals, and designs, and presenting print ng surfaces of relatively large area to give relatively large, unbroken, solid color areas or effects. It isalso-apph- .cable totype having fine lines, swash swings and portions remotefrom the shank'slot such as the ends of a head-letter'GothicH.' i
mold cavity of the'matrix against which the 1 variety of ways. 'For example,'the same may or granular material.
-; Theinvention relates'more particularly to type bodies cast in matrices, forexample, of brass and the like, the type Iorm1ng c av1tyof which maybe produced by forcing into a matrix blank a punch or die provided with a surface conforming to the form of type to be castin the matrix.
We have found that if the surface of-the metal of the type body is cast, is slightly roughened, the type cast therein willproduce better printing and more free from defects.
The roughening of the surface of the matrix referred to .may be accomplished ma be sand-blasted, or etched, iii-any suitable manner, or there may be deposlted on said surfaces any suitable pulverized, powdered As an example of one way of carrying out our invention, We shall describe more particularly the method of roughing the surface of in perspective of a typeor printing body cast therefrom.
As shown in the drawings, 10 indicates a matrix or mold as'is ordinarily used for casting type or printing bodies, such matrix;
, usually being held in line with, or in associated relation with other matrlces in a su1table holder to permit the simultaneous casting of one or more characters on a single type slug. Such matrix ormold may bemade of brass; I I a I vided with a cavity'll with its bottomsurface provided with the character, letter, ornumer al desired, andhere 'shown as the letter Mo,
:indicated by l2. f The letter: M, as here shown, is ofrelatively large, boldface type, I 1- the surface 12 presenting a relatively large;
unbroke nj, solid" color areaf The counter and shoulder {forming "surfaces 1'1 andil and the I face forming surface 12 of the matrix cavity should all herroughened; andthe oblique arearable-maria,-aa a pro LEE w. ROBINSON nn HENRY JONES, OF CHICAGO, rtni-nors, Ass'IGnoEs ToLUnL ow walls 'of the cavityfa's indicated by 13, which forinIt-he meek or heard l-3 o-f the type should alsobe roughened." fThejalmost vertical'si'de v walls 'l lf'o'f thecavitymay"also be roughened Tl1e=rougheningmay be accomplished in a varietyof .VVe have found, forexaini V pie, that*the surfacejmayfbe etched by suitable etChin -HUid, for'example, oxalic acid, T
whicheifects the desired roughening. We
haveindicated-this roughening on the drawings by a slight 'stippling. As shown in Fig.
2, 15indicates, ingenerahthe' entire type or printing body. Theetching fluid may be applied to the surface tobe roughened, -or theentire matrix etching fluid.
Thestrength and kind of etching fluid, and
method of application maybe varied-to suit individual requirementsfWe have found,
for example, .that'oneteasp'oonful of com.- mercial strength oxalic acid dissolved in may besubmerged in the tory etching fluid; and have obtained satis factory results by subjecting the matrix to from ten to fifteen applications of such fluid three ounces of water will'produce a satisfacwith intervening periods of exposure to the;
air. Obviously, however, the desired-etching 1 or roughening could be produced by the usei of other and stronger or weaker etching fluids,
with fewer or moreapplications'.
While we vhave shown and les' ribed certam embod ments of ourinventicn, it is to be un derstood that it is capable of'many modi fications, Changes therefore, in the 'construction and arrangement maybe made withoutdeparting from the spirit and scope ofthe invention as disclosed inthe appended claim s,in which it is our intention to claim broadly as possible in viewofthe prior art.
;What we claim as new, and desire to secure by Letters Patent, is: V r w l. A matrix for the casting of a type body to print a solid color, said matrix having a cavity it-l1 a vroug tll urfac p en elati ly m nu e p c s ons dis ribu ed over substantially the entire area, of the surface of said cavity.
