METHQD FOR REGISTERING CUTS FOR COLOR-PRINTING.

Application filed March 31, 1909. Serial No. 486,848.

Specification of Letters Patent.

Patented July 6, i909.

To all whom it may (-0 acem: Be it known that 1, CHARLES B. .llown, a citizen ol the United States, residing; at New arh, in the couru'y of Essex and State of New erscy, have invented certain new and useful improvements n ltlethods 'l'or Registering Cuts lor Colm'drrinting; and I do hereby declare the following to he a lull, clear, and.

exact description of the invention, such as "will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconuianying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in color printing, and particularly in a method of insuring the dillferent colors being printed. on the same sheet so that they will register and cause the production ole sainple of the typographical art that is symmetrical. The method is quick and positive, and sheets an he printed successively fromcuts or electros so that the dilierent colors .will he in their proper places on the sheet and not overlap each other. i

[is heretol'ore made the cuts for the ditl'erent colors have been placed in blocks and adjusted by means of screws, and at great deal of adjustment is usually necessary to finally get the cuts in place so that they will print at exactly the rightpoint, since the out should hecxactly in register to produce agood copy, and. the slightest variation causes an overlapping of the colors and blank spaces to appear hotweeutlu-mi, which gives an uneven. eii'ect. The invention illustrated in panying drawing, in which- Figure l is a plan of a transparent sheet used in the process, and Fig. is the same sheet with an impression thereon ol' the device or einhleni to he printed, the print being made oi the nsseiuhled cut. Fig. 3 is a view of the cut from which the impression on Fig. 2 is made. lfi l, :3 and U are lace views of electros user lor dill'crenl'. colors on the same dcign to Form lhc'uhole figure. 7 is :1. hi iew oi ll lined up sheet used in the incthoo. Fig.3. H is a face \'l(\\' of u. lilock or panel z'tlso utilimd in this process. Fig. 9 i. saznplc ol the result ol printing); in dill'crent colors from the (ills shown in Figs. 4, and. (S. Fig. i0 is a view illustrating; one stop in the prorrss, and Fig. ll is :1 section showing one the accom- Fig.

of the cuts as in Fig. 4- securcd to the panel shown in Fig. 8.

The electros used in this process are similar to those use]. in the ordinary color printing and there is nothing newiu the productiol'i of the cuts, and the method of using them is the same, that is, they are impressed successively on the same sheet, each being printed. with adillerent color so that after all the inipressions have been made an ornamental and artistic impression is the result.

In Fig. .1 is illustrated a transparentsheet 10 which is made the same dimensions as the cuts and can be used as shown in Fig. l, or it can be printed as in Fig. 2 with the design 11 which is struck up from the printing portion 12 of the cut 13, which cut is the assembled out, and the design 12 is printed in onecolor on the transparent sheet. The transparenfi sheet is provided with periorations 1.4, t iese being shown symmetrically arranged in the figure, hut in an odd shape the perforations can be placed at any point where there is a blank space and it would. not interfere with the printing. The cuts 15, 16 and 17, shown in Figs. 4, 5 and 6, are then. taken, these cuts being provided by an electrotyper end being: ads ted to print the different colors successively. Eu. in its turn has the tr parent she thereon, if the sheet is plain with tn: cages in register, or if the sheet print d as in Fig. 2, with the design or the portion of the design corresponding therewith in register with the cut. Any suitable tool 18, shown in Fig. 10, with a handle 19 is then used and holes 20 are punched in the cuts in register with the holes 14 of the transparent plate. This is done on all of tho elcctros 15, 115 and 17 so that they all have the holes in register. 'lhe cuts are usually made of copper or simi lztr sol'tinz'l-rcriul and are casilv perforated. .i then take a slu-etZl, lquoun in printing olli'ces as a lined up sheet and used at present to lay out the work, and this sheet is lined.

up with the lines so as '1o"p|o].-erly indicatowhcre thoeut to hlythc lined up sheet usuzllly being the size ol' the sheet to he printed, Quads or similar articles :23}, are pasted to the lined up short 21 to form the edges ol the space inv which the out is to he placed to term hearings against which the tra'i-nspurent sheet, can he .hiid so thet it will he held in piece. although these unis or guiding pieces are not ahsolulelx' essential. ill) t The transparent sheet, with its holes 14, is then laid on the lined u sheet and the holes 24 are punched throng. the lined up sheet so that the location of the cut is fixed on the sheet. A block of wood or similar material, known in the printing trade as a panel to which the cuts are to be attached, is then placed under the lined up sheet 21 and the holes in the lined up sheet will then be over the spot where the holes in the cuts 15, 16 and 17 are to come when they are in place. The edges of the lined up sheet 21 and the panel 25 are in register, and while held that way, the tool 18 is used to punch holes through the perforations 24 in the lined up sheet, and the panel is thus provided with I the perforations 26 shown in Fig. 8. There is a panel provided for each of the cuts 15, 16 and 17, that is, there are as many panels as there are going to be impressions or colors printed.

After the perforations, which can be very slight'if desired, have been made, register pegs or pins 27 are driven into the panel 25, these pins-,hein r shown in Fig. 11. Each of the panels is t ius provided with pins and has its out 15, 16 or 17 placed thereon, the holes 20 in the cut fitting over the pins 27 and placing the cut absolutely in its place so that the panels can be successively inserted or used in the same or different presses, preferably flat bed presses, and impressions thereon made on the same sheet, and if the sheets are fed properly, the impressions are bound to he in register. This lining up is quickly done, because more than one out can be fastened to its panel at a time and it is not necessary to wait and use the same bloclr or panel for different cuts, although, if' desired, the same pins can he used for different successive cuts, because the holes in the cuts are in the same place, and when fitted over the same pins, would print in line or register. If a cut ha pens to he insecure on its pins, a small hear ed hrad or tack can be driven through a blank space inthc cut to fixedly secure it to the panel. As a result of the printing steps from the different colors, the design 28 on the sheet 20 is shown, and there is no overlapping or misplacing of any of the different im )ressions.

Having thus (l isci'ibed my invention, what I claim is:

1. The improved method of registering cuts for color-printing which consists in providing a sheet with perforations, )roviding a series of cuts with perforations t n'ough the perforations in the sheet so that they register with the perforations in the sheet, then providing a series of panels with. perforations in register with the perforations in the sheet, 1 placing register pins in the perforations in means for placing the sheet and each cut in register and providing the cuts with perforations through the perforations in the sheet, providing a series of panels with perforations through the perforations in the sheet, placing register pins in the perforations in the panels,

and placing the cuts on the pins.

The improved method of registering cuts for color-printing consisting in providing a transparent sheet, providing a series of cuts adapted to be registered, and a lined-up sheet, placing the transparent sheet on each cut and perforating through the trz'rnspareut sheet and each cut, perforating through the transparm'rt sheet on and in the lined-1n sheet, providing a set of panels, perforating each panel through the lined-up sheet, and securing a cutto each panel through the perforations in each,

4. The improved method of registering cuts for color-printing which consists in providing a transparent sheet of material, providing the sheet with an impression of a cut, ierforating the transparent sheet at poiuls that will not interfere with the prinl ing surface, providing a series of color cuts, placing the transparent sheet on the color cuts with the designs or innairessions in register, perforating tho coloreuts in register with the perforations in the, transparent sheet, providing a lined-u -rshcet, perforating the lincdup sheet to register with the perforated. sheet, providing a set of panclsone for each color out, perforating each panel from the lined-up sheet, the panels and the lined-up sheet having co-acting means for placing them in register, placing register pins in the perforations in the panels, and securing a color cut on the pins on each panel.

5. The improved method of registering cuts for color-printing which consists in pro-.

viding a transparent sheet, and color cuts, perforating the transparent sh et and the color cuts so that their perforations are in register, using the transparent sheet for per forating supports for the color cuts, and

seeming the color cuts on the supports through the perforations in'each.

in testimony, that 1 claim the foregoihg, l. have hereunto set my hand this 27th day of March 1901).
