This series of printing machines are suitable for flat printing of medium and large size ceramic tile billets fired in the first and second time. The printing speed, brick feeding speed and lifting supporting bricks are all controlled by imported brand frequency converters, so as to achieve the effect of accurate positioning and fast printing. The relative error is less than (+0.5%) and the absolute error is less than 1 mm for bricks below dry meters. This machine has the advantages of simple operation, stable operation, less failure rate, bidirectional printing and eliminating Yin and Yang color. It can print in the range of 250x300 to 1200 * 1200, and can also be customized according to user's requirements. Humanized man-machine interface, simple operation, can make the operator easy to use, common printing quantity, printing speed and various parameters have been set in the instrument, are directly displayed on the screen without manual conversion. At present, it is an ideal equipment for flat printing of medium and large size bricks.
