The invention relates to the technical field of resin synthesis, in particular to resin for gravure ink and a preparation method of the resin. The resin is prepared from the following raw materials in parts by weight: 1 to 40 parts of epoxy monomer, 2 to 30 parts of acid and/or acid anhydride, 1 to 25 parts of dihydric alcohol and/or polyhydric alcohol, 0.5 to 10 parts of isocyanate, 0.01 to 8 parts of amine substance and 50 to 100 parts of solvent, the epoxy monomer comprises benzyl glycidyl ether, the dihydric alcohol comprises methyl propylene glycol, and by optimizing the types and dosage of other raw materials, the ink containing the prepared resin can effectively avoid the problems of soluble ink and spots generated after conventional gravure ink and solvent-free glue are compounded; in addition, the ink also has excellent printing performance, drying performance and adhesive force. 本申请涉及树脂合成技术领域，尤其涉及一种用于凹版油墨的树脂及其制备方法；按重量份计，所述树脂的制备原料包括：环氧类单体1-40份、酸和/或酸酐2-30份、二元醇和/或多元醇1-25份、异氰酸酯0.5-10份、胺类物质0.01-8份、溶剂50-1
