Abstract: A data grading transmission method includes steps of enabling a transmitting terminal to grade data according to a preset data security rule and to mark the data with labels; designating transmission routes of the data according to levels of the graded data; and enabling the data to be transmitted from the transmitting terminal to the receiving terminal through the designated transmission routes, and cascading the data having the same label according to the labels of the data. Thereby, grading data according to privacy and designating transmission routes of data reduce network establishment cost and effectively regulate data transmission rate through the data grading transmission method.

Abstract: A process for transferring printed information, in the form of printing ink, from a printed paper to a non-porous substrate by the application of a solvent to the surfaces of an adhesive coating on the printed information surface and a surface of the substrate, followed immediately by the application of pressure to unite the adhesive surfaces together and the subsequent dissolution and removal of the paper leaving the printed information attached to the substrate by means of the adhesive.
