Variable ink technology (gray scale technology) is a technology in the printing industry, refers to  the sprayed drop size can be control, the application of this technology makes the application of UV flatbed printers is more advanced,prospects more wide.
UV flatbed printer's variable ink drop size technology, is because the use of piezoelectric print head, can print with combination of different drops according to different materials to increase the printing speed ,at the same time, to meet the requirements of the pictures on the color density, ensures that the output image accurately, layer clear and transition well-distributed.
