I. Operating principle
When the machine is switched on, the anilox roller will rotate in the ink duct. B y
controlling the clearance between the ink scraper and the anilox roller, you can deliver a
proper amount of ink evenly to the flexographic plate of the circumferential surface of the
printing plate wheel. T he flexographic plate roller carries the ink to the surface of the
material to be printed, which is dried and rolled by the electrically heated drying board to
finish the process. T he printed material is then put into the electric thermostat ventilating
and drying cabinet for about 5 and 6 hours, with the effect of fast color and tolerant laundry.
Environment friendly, the machine is characterized by its speed and efficiency.
Structure
i. Operating principle of photoelectric controlled band-feeder
There are two modes in the setting: ON and OFF. W hen the machine is in the ON mode,
the photoelectric switch must be screened by the material for the machine to start up. When
the material has been printed, the machine stops working.
Ii None Stop Register
First make rough positioning. Press in the printing cylinder. W hen the error of the
printing trace is around 3.5mm, accurate positioning can be made. However, when the
error is greater than 3.5mm, the gear must be withdrawn and turned to the necessary
position. Press in the printing cylinder again to make the error around 3.5mm. Switch on

the machine to make fine adjustment as shown above picture ( None stop register device)
T o save material, the plate cylinder for each color should be installed on approximately
the same position of the corresponding group. If this is done correctly , the position of the
picture to be printed for each color will be very near the register position, which can
minimize the times of register adjustment necessary for the setting and reduce the waste of
the material to be printed. It is recommended that marks be made on the same position of
each plate cylinder or gear, so that the picture on the printing plate adjusted according to
the marks will be very near to the register. When each cylinder is installed on to the printer,
the marks can be used for accurate installation (the accuracy is within a gear). The mark on
the paper belt should be calibrated with the mark on the cylinder and gear of the first group,
and then inch start to move the paper belt to the next color and calibrate with the mark on
the next cylinder. This method can be used for rough peripheral calibration so as to reduce
the waste of trademark belt and the time for setting.

iii. Correct use and maintenance of anilox roller
a. Rules for selecting anilox roller
T he line selection of the anilox roller is determined by the originals duplicated on the
printer. W hen the printing plate is designed, the line of the anilox roller is generally
between 85 and 200. When words or lines are to be printed, it is usually between 180 and
400. To print dense line area, the minimum ratio is 4 to 1 in selecting anilox roller, i.e., to
print 100-line color picture, the minimum line of the anilox roller is 400.
The company standard for the user is 200 lines per inch.
b. Ceramic anilox roller
Each time when the ceramic anilox roller is cleaned, it must be cleaned thoroughly
and checked with a high-powered amplifier. T he cleaning is better to be done when the ink
on the anilox roller is wet. This way, the ink can be effectively stopped from drying in the
roller holes. In general , a special chemical detergent is used to soften and dissolve the ink
in the roller hole. Method: Place the anilox roller in the detergent for a while and then
brush the surface of the roller spirally with a special brush. This is especially effective for
the severely blocked anilox roller with dried ink in the roller holes. After cleaning, pure
alcohol must be used to treat the surface of the roller, including gears and axle. When the
moisture is evaporated, cover the anilox roller with clean paper to prevent dust.

screws, and then encase into anilox roller seat, pressed screw and use hand to rotating
anilox roller and carefully observe both sides of the copper for ink duct and anilox roller
meeting circs , if not, adjus t positioning screws on both sides of copper and let it meeting
better with the anilox roller which is a key factor to ensuring without leak ink . Please let
the masters familiar with . this series machine. And then pressed into the gear and rotati ng
anilox roller, put oil into side hole of copper , and then add ink to regulate the amount of ink.
Ink duct has been mark color group, please installed it with correct mark ink duct.
v. Eccentric labeling roller and central impress roller
Through the rotation of its handle, the eccentric labeling roller makes the left and the
right eccentric covers to rotate synchronously , which uses the eccentric distance to press
the material to be printed onto the circumferential surface of the central impress roller.
W hen this is done, the locking handle of the roller should be tightened clockwise to ensure
that the material to be printed to rotate synchronously at a certain tension with the central
impress roller without slipping or deviating. Thus, the color registering is accurate and the
printing quality is guaranteed.
The central impress roller is the central element of the machine, the material,
processing, and static balance testing of which are very strict. T he accuracy of coaxial ity of
the outer circumferential surface relative to the bearing position at both ends of the main
axle and the vibrating error of the outer circle relative to the rotating center are strictly kept
within the permissible scope of designing and printing. It has also had enough accuracy
reservation to ensure the performance, life and reliability of the whole machine. Besides,
an anti-slippery film is added to the circumferential surface of the central impress roller to
increase the friction factor with the material to be printed during printing process.
