Description

The invention relates to a carbon paper for transferring Characters on a paper laid underneath when applying the characters on a paper laid over it or on the Front of the carbon paper and / or for transferring characters to the back of a paper placed over it Applying characters to the paper laid over it. The format of the carbon paper can be of international standard size, shape size, or any other suitable size be. The carbon paper can be used individually or inserted into a glued stack.

The purpose of the invention is to move characters that are written on a paper onto a paper placed underneath transferred so that the characters on the paper underneath depending on the color of the carbon paper on the The place where the character is transmitted have different colors.

The invention is characterized in that the carbon paper has a number of fields of different colors, which are ordered according to a certain scheme in order to receive transmitted characters that are within a certain field or certain fields have the same color, which is different from the color of the characters in a second field or second fields.

In the following the invention is explained in detail with reference to the drawing.

Show it:

Fig. 1 is a plan view of the front sheet

of three carbon papers glued together with the first two sheets are folded in the lower right corner so that the backs of these sheets are partially visible;

Fig. 2 shows the upper part of three carbon papers Fig. 1, the carbon papers having characters or letters printed in certain fields;

Fig. 3a and 3b carbon paper in the form of a film, which is on the front with different colors is carbon-coated and has the same fields and colors on the back (the film should used for copying with transmitted light) or a film on which characters can be applied (the film is intended to be used in light projectors).

Fig. 1 shows three carbon papers glued together to form a stack. It can be seen that the fronts of the Carbon papers are divided into different fields in which characters or letters can be attached. The color of the Fields is different according to any particular system. Optionally, the front of the carbon paper can be black and white and some of the fields can be printed with letters. The backs of the carbon papers are in the same way as that Front of each carbon paper divided into fields. Optionally, the back can be divided into fields, their arrangement differs from that on the front, with the front, for example, fields according to a standard shape or any type of books used by office workers. Both sides of every carbon paper are so divided into fields according to some system and the fields have different colors. Thus all fields have A. different colors A (B), A (P), A (F) and A (G) on the back of the carbon paper. The fields are coated with coal, while the fields on the front are waxed.

Figure 1 specifically shows three carbon papers in standard form. OB (Y) means a field on the front of the carbon

809828/0735

paper that is waxed and white in color / and what for example, has a red or blue color on the back. OB (Z) means a box that is on the front contains printed text and is colorless or white on the reverse. QB means a field that is coated with carbon. CS means a field of a third form. EA means a field on the back that is partially white. OP means one Diagram field on the front of the carbon paper. C denotes guide numbers.

A (B) means a field on the back of the carbon paper, which colors according to a spectrum or an imitation of which has. A (D) means a field on the back of the carbon paper which has different colors with lines or printed text; A (F) means a field on the back of carbon paper, which has a color different from that of other fields, and the same is true of the fields that are denoted by A (E).

As mentioned above, the fields can be of the same size and in the same way on the front as well as on be arranged on the back. Fig. 1 shows, however, that the fields of different sizes and also of different colors could be. In summary it can be said that the fields on the front are waxed or coated with carbon or with are provided with printed text. Those fields which are coated with carbon produce an inverted picture on the Back of a paper, if characters are written on the front of this paper, if the carbon paper underneath is laid.

The fields can also be distributed in the same way for all three carbon papers shown, while the carbon papers can have different colors on the back. This means that when characters are written on the first carbon paper or a white paper over the carbon paper and if there are white papers between the carbon papers, the characters on the white paper under the first carbon paper

809828/0735

in a particular field are of red color, while the characters within the corresponding field are on the following For example, white paper is blue in color. The characters within the appropriate field on the following white Paper can be blue or a third color. The aim is that the copy characters should have a color, which characterizes the character or characters or draws the reader's attention to this or these characters because of their color. on the other hand all fields in a rubric of all carbon papers can have the same color, which means that all characters that inside those fields are printed in the same color on white paper placed underneath, so that a person then, when she has to notice or pay attention to these signs, know that to look for the signs in blue color so that it is easier for them to notice the correct signs and no other signs exactly. It should be noted that the fields are distributed due to many systems and be of any size within the paper format but the colors of the fields should be of such a nature that they are easily noticed.

Nowadays it often happens that certain parts of a written text or other characters are in a certain Are reproduced in color so that these characters are noticed by the reader. The carbon paper according to the invention gives the characters automatically any desired color so that it is not necessary to color these characters after copying.

According to a second embodiment of the invention, certain parts of a film paper can be within a specified range Field be coated with a certain color carbon. Such a film can be used as carbon paper as well be used to demonstrate the characters with a light projector or the like.

Fig. 3a shows such a film paper, with certain fields A (B), A (E) and A (F) on the back with different colors are coated.

Fig. 3b shows a film paper on which characters or images can be applied and the reverse side has fields in different colors * This film can be used as carbon paper or used in a light projector.

From the foregoing discussion of the invention it can be seen that the fields are distributed in many different ways and can be of different colors, according to a number of differing systems, and that the face of both carbon paper is waxed, carbon-coated or coated with can be provided with a printed text. In the context of the invention, the carbon paper according to the invention can therefore be configured in a variety of ways.
