A method for micro-patterning as well as immobilization of dyes upon polymer reactants with help of a low-strength seen laser for dye-excitation. Extracts from an aqueous medium containing the dye may be attached at any favored spot at the substrate definitely through exposing the area to laser mild. The range of beam can be controlled by the spot-length of immobilized dye, inside the variety of 16 - 150 microns. Micro printing is the manufacturing of recognizable patterns or characters in a published medium at a scale that calls for magnification to examine with the naked eye. To the naked eye, the text might also seem as a strong line. Attempts to breed by strategies of photocopy, picture scanning, or pantograph normally translate as a dotted or solid line, until the replica method can identify and recreate styles to such scale. Microprint is predominantly used as an anti-counterfeiting technique, as its inability to be without problems reproduced through virtual techniques. The immobilization technique is represented by micro-printing numerals, alphabets and patterns on polybutadiene reactants with Rhodamine (Rh6G) dye. Adsorption of laser-excited molecules within the polymer seems to be the mechanism for laser-printing method.
