In the production process of flexographic printing, binding is one of the important links that affect printing quality. Whether label printing, flexible packaging printing, or corrugated box printing, the accuracy of plate installation will directly affect the overlay effect, color reproduction and production efficiency. Therefore, more and more printing companies adopt flexographic printing plate loading machines instead of the traditional manual loading methods to improve loading accuracy and production stability.
So what exactly is a flexible a flexographic printing plate installation machine installation? And how does it work? This paper will introduce the equipment suppliers in detail.
What is a flexible a flexographic printing plate mounting machine?
Flexographic Plate Mounting Machine is a specially designed device that can accurately install a flexo version on a plate cylinders or plate sleeves.
In flexographic printing, each color usually corresponds to a printing plate. If the printing plate installation position appears to deviate, it is very easy to encounter in the printing process imprecision, ghost image, color deviation, etc. Traditional manual plate installation relies on the experience of operators, which not only reduces efficiency, but also makes it difficult to ensure long-term consistency.
plate installation adopts high precision mechanical structure, optical positioning system and digital measurement technology, which helps operators to locate and install plate quickly and greatly improves the accuracy and production efficiency of plate installation.
Why should we use plate installation?
With the increasing demand of the market for printing quality, customers demand more consistency of color, expression of details, delivery time, etc..
With traditional manual installations, businesses often face the following problems:
Long installation time;
There were multiple overprint adjustment;
Increased waste of materials
High dependence on skilled personnel;
There is not enough quality stability between shifts.
After using a professional typesetting machine, can effectively shorten the typesetting time, reduce the number of trial prints, improve the efficiency of equipment startup, reduce the overall production cost.
For large and medium-sized printing enterprises, board hoist has become one of the important equipment to improve competitiveness.
Main components of flexo typesetting machine
Although different brands and models have different configurations, most flexographic typesetting machines consist mainly of the following components:
1. Rack system
The rack is the basic structure of the whole machine, which is used to support roller, guide rail and positioning system.
The high rigidity frame can reduce vibration and deformation and ensure the accuracy of measurement in long-term use.
2. Steel cylinder support mechanism
Used for installing plate cylinders or sleeve.
Some high-end devices support inflatable shafts and rapid replacement systems that can accommodate printing presses of different specifications.
3. CCD camera positioning system
This is one of the core configurations of modern typesetting machines.
High-definition cameras can zoom in and look at printing plate crosshairs, registration marks and reference points to help operators locate micrometer level.
4. Horizontal and vertical adjustment mechanisms
Accurate movement of the printing plate in the direction of X axis and Y axis is realized by precise precision guide rails and adjustment devices.
Some of the automation equipment is also equipped with electric adjustment function, which further improves positioning efficiency.
V. Control system
Used to display images, record installation parameters, and assist operations.
Some smart devices also support digital management and data storage capabilities that allow users to easily and quickly access historical data to enable repeat orders.
How flexible flexographic printing plate installation machine work
The core objective of a flexographic typesetting machine is to ensure the exact correspondence between the position of the printed text and the centerline of the printing plate cylinder.
The basic workflow is as follows:
Step 1: Install the printing plate cylinder.
The operator first installs the plate cylinder or sleeve on the support system of the plate loader and secures it.
The device will adjust the central position according to the cylinder specifications to ensure accurate positioning reference in the future.
Step 2: Establish a baseline
Install machine to establish reference coordinates by mechanical or laser reference lines.
This benchmark will serve as a uniform standard for all color versions.
Step 3: Identify registered trademarks.
Align the CCD camera system with the cross or positioning marks on the printing plate.
The high-definition image is magnified and displayed on the display, making it easy for operators to calibrate accurately.
Step 4: Adjust.
Based on the image, the operator adjusts the printing plate left and right, front and back.
Accurate adjustment accuracy of high-precision equipment usually reaches 0.01 mm.
Step 5: Complete the pasting process.
After confirming the correct position, attach the double-sided tape to the printing plate.
During the whole bonding process, ensure uniform adhesion and avoid blistering and uneven tension.
Step 6: inspection confirmation
After installation, check the position of the positioning mark again to confirm that the relative relationship between the color plate is in accordance with the process requirements.
Then it goes into print production.
The difference between automatic typesetting machine and manual typesetting?
At present the market the flexographic typesetting machines mainly divided into manual and automatic two categories.
plate installation is a low-cost investment, suitable for small order volumes or limited budget enterprises.
The automatic typesetting machine improves typesetting speed and repeatability through electronic control, automatic positioning and digital measurement system.
Automated assembly equipment typically recoups investment costs in a relatively short period of time for enterprises seeking efficient, high-quality production.
What indicators should an enterprise pay attention to when choosing plate installation?
In selecting a a flexographic installation machine, it is recommended to focus on the following:
Installation accuracy
Accuracy directly determines the quality of the overprint.
It is generally recommended to select equipment with positioning accuracy + -0.01mm or higher.
CCD system resolution
The high resolution camera system can identify small positioning marks more clearly and improve the efficiency of plate installation.
Applicable drum range
Ensure that equipment meets current and future product specification requirements.
Easy operation
A user-friendly interface can reduce training costs and improve usage efficiency.
After-sales service capability
Maintenance support is as important as technical services in the long-term operation of the equipment.
Conclusion:
the flexographic printing plate mounting machine is only one link in the production chain, but it has a great influence on printing quality, production efficiency and material loss control.
With the development flexographic printing to high definition, digitization and automation, high precision printing equipment is becoming standard in more and more printing enterprises. For enterprises that want to improve product quality and reduce production costs, choosing a flexible plate installer suitable for their own production needs can not only improve current production efficiency, but also provide more stable technical support for future business development.
