LESLIE J. GOULD AND ROBERT GOULD, O1 TORONTO, ONTARIO, CANADA.-
METHOD FOR OOHPENSA TING FOB UNEVENNESS IN PBINTEBS TYPE.
Application fled lay an,
specification and shown in the accompanying drawings which formpart of the same.
The invention has for its object to produce a new and simple method which will both facilitate and expedite the process of compensatin for unevenness in prmters type, one which will demand very llttle sklll on the part of the operator.
The invention consists mainly of the novel method of performing this work as described in the specification hereinafter following and described in the accompanying drawings, of which Figurel is a vertical sectional view of a make-ready according to the present invention, interposed between the packing and .cylinder, surmounting which is an outline of type. In this view, thepacking, the make ready, and the uneven surface of the typeare for purposes of illustration greatly exaggerated.
Figure 2 is a perspective view of a makeready constructed according to the present invention. i Y
Like numerals of reference indicate corresponding parts in each figure throughout the drawings.
It is customary'after a printers form is compiled to compensate for any unevenness of type by constructing what is known or generally termed a make-ready. This is accomplished by taking a pull oi the form, after which this pull is inspected to ascertain unevenness which will be clearly evident from the faintness and heaviness of portions of the printing. The weak/spots are then bolstered up by pasting one or more pieces of tissue on the back of the pull, the amount of packing for each particular weak spot being more or less a matter of judgevenness O ment and experience.
This pull is then placed upon the cylinder or of pac ing removed from the-cylinder in order to compensate for this padded makeready.
The operation of making-ready will have to be repeated by taking further pulls and similarly atching this" until an absolute type has been arrived'at. In the present invention, the process eonplaten and a corresponding thickness sists of takin a pull of! the form and cutting out the eavy impressions, which are 4926. Serial No. 112,390.
naturally indicative of upstanding or hight pe. fllns pull is placed inregister upon t 1e cylinder and a number of sheets oftissue, waxed upon the underside, placed thereover. Superimposed over these sheets is an .unwaxed tissue in order that when a pull is taken upon this mass this covering tissue may bear the printing and the underlying waxed t ssues take the impression, which impression w ll disturb or break the wax upon the underslde of the tissues causing the typing to show-up white. For the purpose of more clearly examining" this waxed typing, a cardpreferably of dark colouris placed under the tissue sheet. Each sheet is thus examined and, wherever this waxed typing appears, the same is cut out of the sheet; from wh1ch it will be evident that the stronger the impression (caused, of course, by the higher type) the larger the number of sheets from which such impression will be removed, and vice-versawith fainter impresslons.
he waxed sheets to ether with theoriginal pull are then placed beneath the packing on the cylinder, after first having removed a quantity of packing equal to the thickness of this tissue padding.
rom the foregoing it will be evident that this newly devised process of make-ready will most efiiciently, and without requiringskill, judgment or long experience, compensate for any'unevenness which exists in the type of the form.
In Figure 1 of the drawings, the reference numeral 1 designates a make-ready constructed according to the preceding process showing the cut-out portions 2. 3 is the packing and 4 designates the surface of the Figure 2 shows a typical pad of waxed tissues in which 5 are cut-out portions of difierent depths for compensating for type variations.
What we claim is 1. The method of compensating for unevenness in printers type which consists in placinga number of sheets of waxed tissue upon t e cylinder or platen of a press, taking an impression of the set-u type thereupon, cutting out .of the waxe t1ssues ceras a pad beneath the packing to serve as a make-ready.
- 2. The method 0% compensating for untain impressions, and placing these tissues evenness in printers type which consists in placing a number of sheets of waxed tissues together with a superimposed sheet of unwaxed material upon the cylinder or platen of the press, taking a pull upon this mass'so that the uppermost sheet receives the'printing and t e underlying tissue receives the impression; cutting out of the waxed tis sues certain im ressions, and plllacing these tissues as a pad neath the pee 'ng to serve as a make-ready.
3. The method of compensating for unevenness in rinters type which consists in takin a pul oil the set-up form, cutting out o the same the heavy impressions, placin? the mutilated pull in register upon the cy lnder or platen together withe number of superlmposed sheets of tissue of which the uppermost sheet onl is unwaxed; takmg a further pull upon t is mass so that the uppermost sheet receives the printing and the underlying waxed tissue receives the impression; cutting out of the waxed tissues certain impressions, and lacin the pullsand these tissues as a pad neat the paclnng to serve as a make-read Signed at Toronto, Ontario, ganada, this 21st day of May 1926.
