The invention discloses a method for enabling high light fastness of ink of a digital printer to reach the standard. The method comprises the following steps: step 1, weighing 50-60 parts by weight of matrix dye, 15-20 parts by weight of an anti-ultraviolet agent, 5-8 parts by weight of a light stabilizer and 10-20 parts by weight of a leveling agent; step 2, opening a file to be printed in Photoshop software, copying a cyan channel in the file, adding a curve below 40% of the original cyan channel to reduce the cyan channel to be shallow, and adding the curve to the copied channel to deepen the level of the channel; and step 3, opening Ajet software, carrying out channel setting in the Ajet software, importing the file, and printing the file. According to the invention, the high-light-fastness ink is prepared from the matrix dye, the anti-ultraviolet agent, the light stabilizer and the leveling agent, the printed file is processed through the Photoshop software, and meanwhile, the high-light-fastness standard of the digital printer is realized through multi-channel printing arranged in Ajet software, so that the light fastness of printing of the digital printer reaches the fourth level or above, and then the light fastness of the digital printer is improved.
