lithographic press signs are: high-speed smooth, efficient multi-color,
high-quality and flexible, human harmony, digital network centralization,
operation and management integration, intelligent automatic control, safety and
environmental protection standardization. We know that the printing pressure is
very important in terms of lithography, which requires modern offset press
printing pressure adjustment mechanism fast, convenient, safe and accurate.
When using a
printer of a particular type of blanket, printing advanced coating paper requires the
printing pressure of two blanket cylinders between 0.6Mpa, under blankets and
sheets if you do not change the conditions of thickness, printing when the
substrate is converted into a relatively coarse newsprint, it requires three
times the size of the printing pressure, when this happens in practice, few
commercial or semi-commercial press operator will go to replace the blanket or
liner, he is more likely to put this as a minor quality damage typically occurs
when you run different substrates and accept it. If you increase the pressure
in accordance with the requirements, installing a new blanket or thick lining,
so of course, will change the pressure between the blanket and plate, while
also automatically for dot gain and plate wear impact. When the thickness of
the printing when changes occur in the substrate, for example, in
semi-commercial print production from 40g / m2 converted to 85g / m2, there is
the same problem. The blanket will make the problem a different speed with
different surface (allowing transfer of ink is different), blanket different
characteristics and those used for too long sink (lose their elasticity) more
complicated. According to the different types of blankets, the blanket is
reduced in thickness only 0.03mm ~ 0.05mm, when the printing pressure that is
halved. Previously the face of this situation can only honestly to change the
center distance of two cylinders reaches a predetermined printing pressure, in
order to ensure print quality, but it takes a long time to adjust the press, in
today's society and the constant pursuit of printing quality Typographic
efficiency, the operator on the console and gently press the button you can
quickly and accurately adjust the printing pressure to become a reality
born--NipTronic technology.
After the adoption
of the new NipTronic technology, you can systematically eliminate the entire
lithographic work order a weakest link, and with greater precision and faster
speed to control the print quality.
NipTronic
techniques are available through best console between the remote adjustment of
printing pressure plate cylinder and blanket cylinder and blanket cylinder
between the two.
NipTronic
technology is designed and manufactured presses a key innovation in the range
of substrates that can be printed and processing aspects, will bring great
benefits to the user.
NipTronic
sectional view of a bearing apparatus of art, bearing means comprises a proven
conventional roller bearing which is mounted but do not have the slightest
shifting of pre-stretched rail linear movement, the bearing can only be on a
plane movement.
Accurate
impression force is in accordance with the parameters set by a predetermined
value, and the printing blanket cylinder with electric hydraulically pressed
together, after combined pressure of the roller against the locking wedge. When
the pressure off the system is released, the roller wear spring returns to its
original position, this compact integrated system working in a oil-tight
housing. Wallboard printing units are oil-free.
Plate cylinder and
blanket cylinder can leave pressure alone or together from the press. In the
BB-type printing press, the optimum printing pressure between the plate
cylinder and blanket cylinder and blanket cylinder between the two, also can be
used alone or together with remote control settings. BB-type printing press in
the four printing cylinders arranged in a line slightly inclined screw device
mounted on the bearing wall, close to the cylinder body. When working with a
wide tape, this structure there are more advantages: the vibration-related
streaks minimized, eliminating the need for maintenance work shoulder iron and
thus caused.
