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.
4. Rules for selecting anilox roller
The line selection of the anilox roller is determined by the originals duplicated on the
printer. When 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.
Inking part
There is one principle for the ink duct to be put on the printer, i.e., using the least
pressure to finish the ink scraping. When the ink blade is adjusted too tight, the blade will
bend under pressure and the ink will become dried and stuck on the back of the ink blade
due to friction and the accumulation of heat. When this happens, the dried ink will damage
the anilox roller.
When the ink blade is worn out or damaged, it must be replaced.
5. Folding part
The JR-242 flexographic plate trademark printer is equipped with a fastening axle for
folding paper drum, the maximum folding trademark belt being 400mm (Φ16). The folding
switch is in the middle of the fastening axle and the folding tension is controlled by the
electromagnetic clutch, which keeps the trademark belt at a certain tension.
