The different values for the currency will be printed in different colors. A one dollar bill, for example, will not be the same color as a five dollar bill. We hope that this will reduce errors that people might make in giving people the wrong amount of cash.
The text must also be large enough to be easily read. While it is important to have text which is easily readable, we also recognize the historic significance of some information on a bill. For these purposes, it would be appropriate to use a more stylized, old-fashioned font.
If, for example, we had a bill colored with light blues and greens, we might want sharp, striking black text to denote the value of the currency, as opposed to white text, which may be too light to be seen, or a blue, which may be too similar to the rest of the bill to be noticed. These two problems relate to intensity and saturation. Intensity is the brightness of a particular color. The difference between dark blue and light blue, for example, is a difference in intensity. The human eye has an easier time distinguishing between two colors of different intensity.
Saturation is the strength of the color. A low-saturated color is dull and grayish, and a high-saturated color is bright and vivid. The human eye has difficulty distinguishing between colors of similar saturation; for example, a very saturated magenta is hard to distinguish from a very saturated red. Even colors which are vastly different in hue, which is the color of the color (for example, blue or red or green) are difficult to distinguish when their saturation is similar; they seem to vibrate against each other.
The next two examples show the colors that are hard to distinguish, or the ones that simply do not go together:
This, however, looks much better:
Color blindness should not be an issue in our currency, since none of the colors we plan to use are absolutely crucial to recognizing a bill. Colored bills are also more difficult to counterfiet, since an additional production process must be used to colorize the bills.
An excessively long bill would be difficult to handle as well. Additional length gives more than can be caught or get stuck to stuff, thereby increasing the likelihood that the bill would be torn.
To make our bills we will use a special type of paper, similar to the one that is currently used for US currency. It is actually a cotton and linen paper blend that is very difficult to reproduce. Also, we will use interwoven red and blue fibers the absence of which in a fake bill will make it esily identifiable. A similar idea is behind the security threads that are used in $100 bills today
Another security feature is the image of the bill itself. Just as the currently used banknotes our bills will have intricate lines and designs that cannot be reproduce by photocopying. In particular, the new bills would have an miniature image of Mikky Mouse's head.
Also the new banknotes will have miniature lettering, that cannot be seen without a magnifying device, and which will look like a simple line when photocopied.
We will also use a special ink, which cannot be manufactured without the proper equipment and the knowledge of the secret formula.
Another feature that is used in banknotes of may countries is watermarks, that can be seen if the bill is held to the light. On our bills we will have a watermark containing the image of the flag of the United States.
The final, and the most "secure" security feature that our bills will contain is a hologram. Holograms are virtually impossible to create without sophisticated equipment.
If any of these features is missing or corrupted, one can safely conclude that the bill is fake.
