Abstract
A magnetizable ink contains at least 65% of magnetizable particles having a modal diameter between 3 μm and 10 μm. The particles may have a size distribution with 0% above 18 micron and not greater than 20% under 0.5 micron. The particles may have a surface area less than 50,000 cmper cm, and/or the ink may have a viscosity less than 16,000 cps when ready to print. Where the particles are rounded, magnetically soft iron particles, the surface area may be less than 12,000 cmper cmand the viscosity may be less than 1,500 cps.
