The water in the middle is small, but the water on both sides will drop, indicating that the two ends of the water stick are big and the middle is thin. The essence is that the pressure adjustment between the two is too large, the colloid in the middle is squeezed to both ends, which makes the two ends expand, and the water in the middle is squeezed out, and no water reaches the printing plate. The bright water at both ends is most of the water that is squeezed by the water stick.

GTO waterway adjustment is simple. The steps are as follows:

1, eliminate the mechanical action fault of the waterway.

2, in addition to the water bar colloid integrity without cracks; The appearance of the water bar velvet sleeve is intact and the packaging is uniform; The bearings at both ends of the water bar are in good condition without clearance, and the rotation is stable and flexible.

3. Adjust the pressure between the waterline lever and the bucket lever. The last step is to adjust the pressure of the back plate. When the feeler gauge is pulled out, the pressure between every two feelers is the best pressure to drive one feeler gauge to rotate, and the feeler gauge of the feeler gauge should be uniform.
