The only information I am able to find on this topic is under the assumption that the duplication would be in print format:
Some of the most common conditions are (not all apply to every country):
- Size - smaller or larger than original, the amount varies by country
- Color - black & white reproductions only or the use of distinctly different colors from original
- One-side - reproductions cannot be double-sided
- Surface Area - only a certain percentage of the overall surface of one side of the bill may be depicted
- Orientation - currency must be at an angle within the illustration
- Labeling - placing the word "Specimen" or "Sample" across the illustration
- Material - some types of reproductions can only be placed on materials that are not paper or paper-like
- Permission - in some countries you must request permission in writing before reproducing banknotes in advertising or for educational purposes
- Creative Materials - disposal of scans, negatives, plates, or other materials used in creating the currency reproductions
I'm just looking to use elements of currency as part of a mobile website theme; there's a very obvious lack of the possibility of mistaking anything as counterfeit. But, I'm aware of the sensitivity of this, so I want to make sure I'm not taking any chances on getting caught up on a technicality; the prison industrial complex is booming business now.
I suppose just using portions of a US dollar bill might be the safest route, but I just need to know what my limitations are before heading down this path.
Lastly, where's a great place to find this type of information without risking a tour of Guantanamo?
