740mm Multi-Color Sheet-Fed Offset Printing Machine

740mm Multi-Color Sheet-Fed Offset Printing Machine

Product Introduction:

Ecoo JY 744 has built a new generation of four-open multi-color offset press, which adopts pneumatic automatic plate clamping system, three-axis automatic plate adjusting system controlled by DC permanent magnet, accurate automatic pressure regulating system and bus electric control system of Mitsubishi CC-LINK communication mode, perfectly showing the characteristics of dexterity, intelligence and high efficiency of four-open heavy-duty printing press.
Stainless steel spraying embossing and printing plate cylinders greatly prolong the service life of the whole machine.
CIP4 can easily form a digital workflow with pre-press CTP and post-press and preset ink quantity and color, thus greatly reducing the dependence of printing enterprises on the experience of printing technicians.
Under certain conditions, through INTERNET monitoring and control of the printing press operating conditions and various parameter changes, the popular UV printing, glazing and other printing processes, as well as the automatic washing of the blanket cylinder, ink roller, etc. can be easily installed, greatly improving The scalability of product functions.
 

Specification:

Structural Features:

1. Semi-automatic plate loading device, convenient for the operator to quickly and accurately plate, reducing the auxiliary time of printing plate loading.

2. Paper thickness preset function enables the operator to automatically, quickly and synchronously adjust the printing pressure of each color group when printing paper of different thickness.

3. When the paper on the machine is not stopped to meet the printing requirements of the machine, replace the new paper pile; Reduce the printing of thick paper, long version of the live downtime to change paper time.

4. Electrical use Mitsubishi mature process bus module CC-LINKffl line control, with communication between units to achieve contact.

5. The printing system composed of double-diameter impression cylinder and double-diameter paper transfer cylinder is conducive to the printing of thick paper and cardboard. At the same time, it reduces the number of paper handovers and is conducive to accurate overprinting.

6. Centralized control of the DC electric pull plate control of the three directions (circumferential, axial, oblique) of the plate loading error, can be convenient and quick calibration of the four-color printing plate, reduce the printing auxiliary time.

7. Five-roller structure and moving intermediate rollers can effectively reduce ghost generation, fast ink balance and reduce the amount of over-plate paper.

8. The remote control ink fountain composed of 23 partitions is adjusted through the touch screen of the main console. It has the functions of ink quantity preset and job storage. It can easily retrieve relevant printing data and quickly enter the printing state.
