Abstract:

According to the production practice of digital printing, the current situation of technology application of reactive dyes direct injection printing was analyzed, the problems which existed in application of reactive dyes direct injection printing were summarized, these problems were that such as the method of mixing color was not suitable, color reproducibility was poor, color brilliance was not high, the size of the ink drops couldn’t be adjusted according to pattern, and the sizing system was imperfection and etc, the reasons of the existence of these problems were analyzed, and the corresponding suggestion for solving these questions were put forward. Through these problems being put forward, It was hoped that these problems would be paid close attention to by these people who are engaged in reactive dyes direct injection printing and its related technology, the production of digital printing equipment and technology of the digital printing were guided to improve, and the quality and grade of the digital printing product were realized to enhance overall.

Key words: reactive dye, digital printing, direct injection of printing, method of mixing color
