METHOD OF APPLYING PROTECTIVE COLORING IN THE PRINTING OF DOCUMENTS REPRESENTING VALUE Filed Aug. 2, 1954 l Il. muni;
Patented July 28, 1936 UNITED stars FFE@ METHOD OF APPLYING PROTECTIVE COLORING IN THE PRINTING 0F DOCU- Y MENTS i REPRESENTING VALUE Application August 2, 1934,' Serial' No.v 738,137 In Great Britain August 9, 1933V 9 Claims.
This invention relates: to an improved method of applying protective coloring in the printing of documents representing, or intended-to represent, value, such, for example, as bonds,- share warrants, bills, notes, cheques and the like and has for its object to render same as difficult of fraudulent reproduction asl possible. y
It: has been. customary to employ for this purpose one, or a combination ot'two or more colors, chosen to produce protective antiphotographic tints, that is' to sayV tints whichunderlie th'e main printing of the document andare oi such a color or Anature that they cannot be photographically separated from the main printing for the purpose of making afraudulent imitation of the document. n*
As an additional safeguard a somewhat intricate pattern has been employed, which is applied in a succession of`two or more printingsin close register, each printing, being preferably a dier'- ent color.
In multi-*color printing work, where the ink in the duct, leading tothe roll which feeds ther inking roller, isv divided into'- separa-te colors, a merg-- ing of the bands of colorscan 'be-produced, regu-Y lated anddetermined by the amount of lateral. oscillating movement of the inking mechanism, the result being to produce a rainbow eiiect.
According to this invention there is employed in the printing of a document, which is to be rendered as fraud-proof as possible the method of applying a protective anti-photographic pattern to a part (or parts) of the document by a rst printing operation employing two or more bands of colors and subsequently applying, by means of a second printing operation, a further pattern to another part or parts of said document, the two printings being in close register in such a way as to form a substantially continuous pattern, whilst the bands of colors are discontinuous.
The invention moreover embraces the method of applying protective colorings to documents consisting in subjecting the sheet of paper to two successive printing operations, whereby a substantially continuous pattern is applied to the paper by the two impressions, each impression comprising two or more bands of color merging at their edges, the bands of colors of the rst impression being substantially discontinuous with respect to the bands of colors of the second impression.
One method of printing a document in accordance with the invention consists in applying a close register pattern to a sheet in two impressions, each formed by a printing block inked with two or; more bands of colors merging at their One embodiment of this invention is illustrated,
merely by way of example, in the accompanying drawing:-
. Figs. l and 2 show the separate impressions obtained from two printing plates A and B respectively and Fig. 3 illustrates the combined impressions produced by the' two plates A and B.
In order to make the description clear, the anti- L photographic tint or pattern is; represented by aV series of circles, it being understood however that the pattern would bean intricate one composed of ne and numerous characters or lines, same underlying the main printing of the document,
which is not shownv in the drawing. It will be assumed that the desired pattern is obtained by two printings produced by the plates A and B, but ifl desired more than two printing operations may be employed.
The plate A produces an impression on a part of the document, the ink in the duct being divided into three bands namely, blue, red and blue. By giving an oscillating movement to the rollers feeding the ink to the inking roller, a merging of the colors is brought about in such a way as to produce a rainbow effect, which operation is commonly known as rainbowing The colors in the drawing are shown according to the heraldic convention, and as it is not possible to illustrate the rainbow effect in black and white, this is diagrammatically illustrated by the brackets a a and by b. It is pointed out however that the merging or rainbow eiect is a gradual one, and that there is no hard and fast line of division between the bands of colors.
Fig. 2 shows the impression produced on a sheet of paper by plate B using three bands of colors, namely green, purple, and green, which are rainbowed as shown diagrammatically by the brackets c c and d d.
It will be observed that in Figs 1 and 2 certain portions 2 of the impression have no pattern, same being merely stippled with an appropriate color in order to constitute a background for that part of the main printing of the document, such for example as a portrait, which could not suitably be applied on top of the anti-photographic pattern. This stippling however forms no part of the present invention.
Assuming now that a sheet of paper shown in Fig. 1, which is produced by plate A, is subjected to a second printing operation by plate B in close register with the rst impression, the result.
shown in Fig. 3 will be obtained. It will be seen that the pattern produced by the two impressions is substantially continuous, the two meeting one another in close register along the lines 3 Whilst the rainbowing eect or bands of color are substantially discontinuous.
Thus in effect it will be seen that the sheet of paper is subjected to successive printing operations, each impression producing per se a relatively spaced or disjointed pattern with twoor more merging bands of colors, whilst the sum vof the two or more impressions results in the production of a substantially composite pattern in close register without overlapping in such a way that the bands of colors of one impression are discontinuous with respect to the bands of colors of the other impression or impressions,
A document printed in accordance with this invention presents an attractive appearance, `and moreover makes it very diiicult to produce a fraudulent reproduction.
What I claim and desire to secure by Letters Patent is:-
1. The method which comprises printing a v background pattern upon a portion of a paper in a plurality of bands of diversified colors, and printing a background pattern upon an adjacent portion of the paper in close register with the pattern of the rst printed portion and in bands of diversified colors contrasting with the bands of color of the first printing along at least a portion of adjacent edges of the respective printed portions.
2. In the printing of a backgroundcoloring upon paper, the process which comprises printing a pattern upon a portion of the paper in a plurality of bands of diversified colors, and printing a pattern upon adjacent portions of the paper in close register with the pattern of the first-printed portions and in a plurality of color bands which each contrast with the contiguous portions of the color bands of the first printed portions.
3. In the printing of a fraud-preventing background pattern upon paper, the process which comprises printing a pattern upon portions of the paper in a.p1urality of bands of color, and printing a pattern upon other portions of the paper in close register with the pattern of the rst printed portion and in a plurality of bands of color that are discontinuous with the bands of color of the rst printed portions.
4. A printing process as claimed in claim 3, wherein the bands oflcolor of at least one of said printings merge at their edges.
5. The process of printing a close register background pattern upon paper in two impressions which comprises printing the pattern upon spaced portions of the paper in bands of color, and printing the pattern upon adjacent non-overlapping f portions of the paper in bands of color contrasting with the pattern color at the adjacent edges of the rst printed portions.
6. A process asrclaimed in claim 5, wherein the bands of color of both-printings are all parallel to each other. Y
7. A process as claimed in claim 5, wherein the bands of color of at least one of theprintings merge into each other,
8. A process as claimed in claim 5, wherein t each band of color of one printing contrasts withv tern elements are arranged in bands of different" colors, the pattern elements of each two adjacent portions being in closeregister to f orrn com-'- ponent parts of a single substantially continuous background design and the coloring of the pattern elements being discontinuous along at least a part of the junction of the said adjacent portions.
