At present, the mainstream S3200 print head solution in the market is the four-head S3200, and the mainstream 4720 print head solution is the eight-head 4720. We will analyze the differences between the two print head solutions in detail from the aspects of printing speed and printing accuracy. Printing speed At present, the normal production mode 2PASS printing speed of the four-head S3200 machine in the market is about 190 square meters per hour, while the 2PASS production mode printing speed of the 8-head 4720 machines is about 270 square meters per hour, which is highly competitive, and the entire program has passed the market. Verification, relatively mature. There is a big gap between the printing speed of the four-head S3200 machine and the eight-head 4720 machines. In order to increase the production printing speed, a 1PASS printing solution is needed, so that the entire production printing speed can be up to about 300 square meters per hour, which is a significant increa...
