Magnetic block printing ink

Abstract

A magnetic block ink consists of magnetic pigment, connecting material, solvent, drier, wetting material and filler, connecting material comprises bakelite 1 for improving ink yield value, bakelite 2 for improving ink fluidity, flax-seed oil and tung oil, solvent is mineral oil, drier comprises drier 1 and drier 2with surface oxidation dry, internal dry and complex dry functions, wetting material is long oil alkyd resin, and filler is gum calcium, calcium carbonate or gas-phase silicon dioxide. It achieves low cost, better quality and high efficiency.

Description

technical field [0001] The invention relates to a magnetic ink, in particular to a magnetic embossing ink. Background technique [0002] With the increasing number of social and economic exchanges, the amount of check settlement is increasing, and manual sorting is difficult to meet the growing requirements. It is an inevitable trend to use E13B numbers to realize sorting and machine reading. The magnetic checks widely used in existing bank commercial papers The number is usually printed by magnetic transfer printing. The magnetic transfer printing technology uses the print head to hit the tape to print the E13B number on the ticket below the tape. Since the magnetic transfer machine can only print 3 sheets of products at a time, the production efficiency is low. Magnetic transfer printing equipment is expensive, tape and other consumables are expensive, and manual dialing is required when printing 32-digit E13B numbers, which cannot meet the requirements of mass production....
