When the scraper is running, the pattern of the page moves in the direction of force, and the pattern on the fabric is partially Or all of them are misaligned to varying degrees.

④ During the running of the printing plate, the printed garment piece or piece of cloth is affected, and the printed pattern is moved on the printing table.
