12. Temperature control and display of the lower drying board: The 6 positive 2
negative types is used for the temperature control of two-color group, and the 3 positive 1
negative type is used for the temperature control of single-color group.
13. Electric switch of the lower drying board: When the 6 positive 2 negative type is
used only for the temperature control of six-color group arranged in satellite form, or the 3
positive 1 negative type is used for the temperature control of two-color group, the lower
drying board can be switched off.
Make sure that the machine is in OFF position. Thread the material to be printed
along the threading line according to the sketch diagram of the purchased type of the
machine.
Loosen screw, take out screw cover, and place the roller wheel threaded with the
flexographic plate and the accessory gear with the confirmed correct number of gears into
the bearing holes at both ends of the corresponding printing color position.
Mesh the accessory gear of the plate roller wheel with the central impression roller
gear, and then lock tightly the locknut.
Run the machine slowly and adjust every adjustable handles of the adjustable plate
assembly. Adjust the ink between the printing plate wheel and the anilox roller and the
contact pressure and accuracy on the impression roller till satisfactory. In printing practice,
the contact pressure between the plate roller and the material to be printed is generally very
small, sometimes approaching “zero”, i.e., the “zero pressure” contact in flexographic plate
printing terms. In short, adjust the machine till the printed pictures, words and lines are
clear and satisfactory. Needless to say, practice makes perfect. Everyone can learn and
improve his skills with time going by.
In normal printing, adjust the speed knob until the rotation or the ink amount
corresponds with the electric drying speed of the machine.
The maximum printing speed can reach 60 meters per minute.
14. The switch-off procedure is as follows: Turn off all the electric drying knobs →
turn off the stop knob → switch off the power switch of the main control box → switch off
the external power source.
