The present invention relates to a new technique in security Numbering with the help of specific styles of engraved numbering wheels which have been designed to protect security documents involving currencies, cheques and other Bank Notes. This unique concept is based on numbering with two numbering wheels having partial images of the same numerals in two separate boxes which when printed in register will make each of the numerals appear in two colours (one numeral split into two parts each in one colour) to achieve the intended result. |
