PURPOSE: A natural dye pulverizing method for paper dyeing is provided to improve dyeability, workability and preservation property through pulverization and weightening dyes. CONSTITUTION: A natural dye pulverizing method for paper dyeing comprises the steps of: (S1) extracting colorant with 10 times liquid; (S2) filtering the extract; (S3) concentrating the filtrate to 1/10 (v/v); (S4) injecting dyeing materials into the concentrated dyes; and (S5) freezing/drying the dyes and pulverizing the dried materials. The dye is at least one selected from cationic starch, oxidized starch, soybean protein, skimmed milk powder, polyacrylamide(cationic, anionic, amphoteric-PAM), and nano sliver.
