Based on the original wave printing, the new generation printer innovates the intelligent interleaving printing technology-the I² technology. The intelligent interleaving printing technology can effectively improve the Banding and Pass phenomena in the printing process and make the printing quality reach the ideal state. The printing head can print seven kinds of ink droplets of different sizes. According to the different printing materials, customers can choose to use different combinations of ink droplets to meet the requirements of color saturation and printing accuracy. Seven level variable ink drop printing technology to ensure that the output of the image ink point more fine, more delicate screen, more distinct layers. The original two-stage ink bag ink supply technology, using negative pressure ink supply. The interior of the secondary ink bag is sealed to ensure that the ink is free from external air, to provide stable ink supply for the printing head, and to realize high speed printing.
