Controlling alumina aggregate particle shape strongly influences production processing and resulting print quality for glossy inkjet. Especially primary particle size and specific surface area influence the paper and film coating processing related features as well as the resulting print result. AEROXIDE® Alu C, AEROXIDE® Alu 65 and the developmental grade VP Alu 3 are examples how to design particles for specific coating and printing needs.
