The invention relates to microsphere foaming printing ink and a printing process and application thereof, the microsphere foaming printing ink comprises the following components in percentage by mass: 16-22% of microcapsules, 20-30% of acrylate copolymer, 20-30% of color paste, 20-30% of urea and 20-30% of auxiliaries, and the sum of the mass percentages of the microcapsules, the acrylate copolymer, the color paste, the urea and the auxiliaries is 100%. The mass percent of the acrylate copolymer in the microsphere foaming ink is 58%-64%. According to the microsphere foaming ink, the printing quality and the printing precision can be well guaranteed, and after drying and foaming of a screen printing machine are combined, the printed ink surface is smooth and flat, and the height and the velvet degree are good. The microsphere foaming ink provided by the invention is higher in inclusiveness to packaging materials, can be widely applied to various materials, is very high in precision, is higher in precision comp
