The problems that should be paid attention to in the printing process of balloons because the surface pressure of balloons will make the screen concave.
300 mesh screen is generally recommended for latex balloon printing. Other special balloons, such as vacuum balloons and advertising balloons, can be adjusted properly when the pattern printing effect is not affected. The screen frame of silk screen is generally made of aluminum, and the screen is bonded and fixed on the frame. The size of the inner ring of the frame depends on the size of the printed pattern. The front and back direction or left and right ends of the rubber scraper in the frame are generally 30mm-35mm away from the pattern, so that when the ink and rubber scraper are placed on the screen, the screen can have sufficient elasticity.
During printing, the balloon shall be fully inflated until the printing frame is pressed down to the lowest point and the balloon does not break. In order to achieve a good printing effect, the position of the pattern in the screen frame should be in safe contact with the surface of the balloon after pressing down. Because when the balloon is printed, the surface pressure will make the screen concave. The printing knife and ink returning knife can be adjusted to contact with the screen, and the screen is easy to break when the pressure of the printing knife is too large.
Printing ink is usually latex ink. If the ink is too thick, you can add 10% - 20% open oil (diluent) to make the printed pattern clear without stickiness between the screen frame.
