This report describes R2T2, a dynamic thermal printing process. Print quality is dependent on many printing parameters interacting with each other during ink transfer. The entire transfer process can be divided into five stages: heat, melt, adhesion, separation, and solidification. The report deals with the ink and printing parameters most pertinent to print quality. The ink transfer temperature determines the printing power as well as the ribbon stability. The viscoelasticity and adhesive property of the ink-melt influences the actual print quality. Contact pressure, heat transfer, ink adhesion, and separation also play important roles. The effects of all these factors and the limitations of print speed arc discussed as well.
