The invention discloses a manufacture method of a colorful flexible printing corrugated box, comprising six steps such as corrugated bonding, drying, throwing and cutting, preparing ink, forme and flexible printing. A corrugated cardboard with special standard is taken as a printing material, thus leading no settlement phenomenon between the corrugated peak and corrugated valley of the corrugated cardboard to occur and ensuring clear printed patterns. By adopting no-shaft transmission flexible printing, overprinting precision of each color group can be independently adjusted, thus improving the overprinting precision of the printed products, and greatly improving the printing quality. By adopting knurled rolls in grid shape and ceramic material spayed on the surface of the knurled rolls, the surface performance of the knurled rolls is improved, the flexible printing quality is improved, the service life of the knurled rolls is prolonged, and the printing cost is saved. The content of the connecting material in ink is increased and the consistency of dye is increased, thus reaching required ink film thickness under low ink transmission quantity, and reaching the requirement of stable and full colors, high vividness of the printed product and good glossiness.
