Abstract:
1. A method for printing raised text and/or graphics on a single sheet of substrate; wherein said method is carried out on a home-based and/or office based ink jet printer; wherein said method comprises steps of: a controlled amount of two or more reactive materials; each prepared with different formulations, and comprising water soluble metal salts having very low viscosity of less than 10 centipoise, preferably in a range of 1.9 to 3.5 Cps; from at least two common cartridges attached to a single print head are sprayed simultaneously on said substrate combining and mixing with each other; wherein said controlled amount produces a new nano particle mixture during a chemical reaction; wherein all the steps above including preparation, spraying and mixing of said reactive materials are carried out in room temperature, and wherein said chemical reaction gradually creates a raised printed area of less than 10 microns when left stand alone; wherein a content of said reactive materials in said prepared inks is more than 5%, preferably from 5 to 25% and more preferably form 10 to 25% by weight of total weight of said prepared inks.
