10 Claims. (01101-131) My invention relates to an improvementv in reproducing masters, and the method of their formation and use. 1
One purpose is the provision of a master or impression member for use yin duplicating lnvoices, shipping instructions, orders and the like.
Another purpose is the provision of a method of and means for masking out part of such a master when different portions thereof are desired in different reproductions or impressions.
Another purpose is the provision of an improved combined master and mask, Aor primary master and secondary master, in which the mask or secondary master is readily removably secured directly to the primary masterk without the need of intermediary securingmeans, clamps or the like.
Other purposes will appear fromjime to time in the course of the specification and claims.
I illustrate my invention more or less diagrammatically in the accompanying drawing wherein:
Fig. 1 is a plan view illustrating a single mask applied to a reproducing master;
Fig. 2 illustrates the application of a plurality of individual masks to a single master;
Fig.'3 illustrates the application to a master of a mask or supplemental master having reproducible material on its rear face;
Fig, 4 illustrates a master with a coa-ting strip applied to one margin;
Fig. 5 is a section on the line 5-5 of Fig. 1;
Fig. 6 illustrates a mask with a coating strip applied to one margin thereof; and
Fig. y'l is a section on the line 1-1 of Fig. 6.
Like pa-rts are indicated .by like symbols throughout the specification and drawing.
My invention should be considered in-connection with the duplicating process which is performed by making a master of the material which is to be duplicated, by typing with carbon paper, writing, or drawing with proper inks,
crayons or pencils.- The material to be transferred to the finished paper mustappear in reverse on the master, an arrangement which may be effected by putting carbon against the back of the master a-nd thus. by pressure, applying it to the back of the master. When the master is finished, it may be fastened to a cylinder or press, not illustrated herein, and a revolution of the cylinder maybe used to press the master against a sheet 'of impression paper, which may for exainple be mechanically wetted with a suitable solution just before being brought into contact with the master. The pressure of the wetted sheet against the master transfers a part of the pigone or another of the copies.
ment from the master tothe impression paper, and thus makes a copy of whateverimpression or impressions are exposedon the master.
A good material or paper for a master is a paper which is coated with a substance which retains a largedegree of pigment from the carbon, pencil, crayon or ink, and releases it to the wetted impression paper in a thin film. Such a coating may be similar to a dull vsurface enamel coating which picks easily when any tacky substance is broughtinto contact with itand removed. In other words, the characteristics of the paper for the master proper or for the impression receiving surface of the master is a relatively loose or rough or dull finish.
It often happens that a master is used to re produce a plurality of copies where parts of the material on the master should be omitted from `As an example of what my invention avoids or replaces, the following steps may belisted:
(1) When an order that involves several items is received, it should normally be acknowledged as a unit. The order is therefore typed as a unit, and one acknowledgment run off from the master, all of the impression of the master vbeing at that time exposed.
(2) Thereafter, if the order must be handled in several units, the entire order is run off as many times as is necessary, and a hand operation tional hand operations oneach copy are necessary to indicate the important portions of the impression received from the master, or to cross out or cancel the unimportant or undesired items. In addition to the time involved in the above mentioned hand operation and the chance of error, the finished product is unattractivel in appearance, particularly for invoices or other outgoing forms. As a result, many concerns forego invoicingby this process, and thus duplicate the amount of work done by invoicing as a separate operation.
In my invention I provide means readily se-- cured to or removed from the master itself, which are effective to mask out all undesired items, or
to add substitute or additional items. Considering, for ei'rample, Fig. 1, a primary master sheet is indicated at I. Along its margin, as at 2, Is a hardened or treated marginal area. I may, for example, apply a hardeningl agent which will eliminate the "picking usually found in a coated paper such as the paper necessary for the master, or which will eliminate any disturbance or removal of fibers in uncoated papers. A wide variety of hardening .agents is effective, for example cellulose acetate, nitrocellulose lacquer, varnish, starch, glue, rosin, Cellophane, glassine, or any other substance which will prevent loss of loose fibers or of coating by the application and removal of an adhesive.
3 indicates the impressions on the master which are to be reproduced. Assuming that some of the material isto be omitted from any given impression or impressions, I may apply a mask li, which has a marginal or edge portion 5, which may be provided with any suitable pressure adhesive. All that is necessary to apply the mask is to lay the mask in position, as shown in Fig. 1, with the adhesive portion 5 opposed to the hardened marginal portion 2 of the primary master. The mere application of pressure is suicient to hold the mask in position, and the master I may be applied to any suitable printing mechanism, or run on or through any suitable roll or rolls. Only the impression of the exposed portion of the material 3 can be taken.
Thereafter, if the entire impression is again desired, the mask form may be removed by merely jerking it off, as a little tension applied thereto will break the bond between the adhesive and the hardened portion 2 of the master I. However, because of the nature of the hardened portion 2 of the master I, the paper will not be pulled away, and little, if any, of the adhesive will be left on the primary master. On the contrary, it adheres almost entirely to the treated edge portion ofthe mask itself, and the mask can be stored by merely being pressed against a treated or hardened storage strip on a wall, in a drawer, file or the like.
It will be understood that I may employ a single mask, or a plurality of masks, as shown for example in Fig. 2, where it is desirable to blank out a scattered sequence of items. It will be further understood that, whereas my invention may be applied merely to blanking out portions of a primary master, it may equally readily be applied to inserting portions, either to ll blanks in a partially impressed master, or to substitute overlying material for the material blanked out in the primary master. I thus illustrate in Fig. 3 a combined mask and secondary master, indicated at 6, with its adhesive top portion 1. It may be applied to the master I just as in the case of the masks of Figs. 1 and 2, but it also serves as a supplemental or secondary master, the material 8 on the back thereof being reproduced at the same time as is the exposed material '3 on the primary master.
It will be understood that where in my claims I describe the mask or secondary master as carrying an adhesive, or wherein I describe a hardening treatment or area of the primary master, such adhesive material or such primary hardened area may be formed by treatment of the primary and secondary masters or the masks themselves, or may be obtained by superposition of additional layers of material. Thus, it is under some circumstances practical to take an ordinary master of relatively soft or rough surface and apply to the edge thereof a surface coating or tape, or overlay, which may be relatively permanently secured to the primary master, as shown at 8 in Fig. 4, and which has an upper surfacev 9 sufficiently hard or firm or smooth to perform the same function as the treated marginal edge 2 of Fig. l. Similarly, adhesive tape or adhesive coated material may be. applied in strip form to the edge of the mask or secondary masters shown in Figs. 6 and as at Il.
I realize, therefore, that whereas I have described and shown a practical and operative article of manufacture, nevertheless many changes may be made in the size, shape, number and disposition of parts, and in the steps of formation and use without departing from the spirit of my invention. I wish my description and drawing, therefore, to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to the specific showing of my description and drawing.
