In label printing industry, market for product quality, speed of delivery, production costs of more and more stringent requirements. Whether it is daily labeling, food labels, drug labeling, or anti-counterfeiting labeling, printing enterprises need to maintain stable registration accuracy and efficient production capacity.
the flexographic plate mounting machine as an important auxiliary equipment of flexographic printing directly affects the installation quality, registration accuracy and start-up time of flexo printing. Therefore, for label printing house, choosing a plate assembly machine suitable for its own production needs affects not only the current production efficiency, but also the future development potential of the company.
So what factors do label printing companies need to look out for when buying a flexographic plate mounting machine?
Why is label printing more demanding for board cranes?
Compared with corrugated cardboard box printing and other fields, label printing products generally have the following characteristics:
High graphic details; rich Rich color gradation; strict multicolor registration requirements; frequent order batches and changes; high customer quality consistency requirements.
Especially in areas such as cosmetics labels, wine labels and high-end packaging labels, even small registration errors can lead to the scrapping of entire batches of products. Therefore, label printing companies often have higher requirements for the installation accuracy and efficiency of sheet metal.
First: pay attention to Plate Mounting Accuracy
The key index of plate loader is positioning accuracy.
If the location is deviated during installation, subsequent printing will require additional time for registration adjustments, increasing material waste and affecting delivery cycles.
In general:
Normal label printing, recommended accuracy ± 0.05mm; high-end label printing, recommended ± 0.02mm; precision labels and security label, recommended ± 0.01mm.
For enterprises that consistently take on high value-added orders, high precision equipment can significantly improve product stability.
From the point of view of practical application, the higher the installation accuracy, the less registration adjustments is required after starting.
Second: Choose a CCD Vision Positioning System
Modern flexographic plate mounting machines widely uses CCD vision positioning technology.
By using a high-definition camera to zoom in on the crosshairs and positioning marks on the printing plate, operators can more accurately install the plates.
When choosing a device, focus on:
Camera resolution;
Image magnification;
Image display clarity;
Autofocus function;
Image measurement function.
For label printing companies, the performance of the CCD system often directly determines the efficiency and user experience.
Especially when printing small text, QR codes, and high-line-count halftone dots, the advantages of a high-quality visual system are even more pronounced.
Third: Select equipment specification according to printing width.
Label printing companies have different Equipment configurations.
Before purchasing a typesetting machine, please confirm the maximum width of your printing press and the size of the cylinder.
Common label printing widths include:
330mm
370mm
420mm
520mm
670mm
In the event of future expansion plans, it is recommended that some capacity be reserved for equipment of different specifications in order to avoid excessive investment in subsequent equipment upgrades.
The wider the scope of applicability of the equipment, the more flexible future production arrangements will be.
Fourth: Assess the Level of Automation
The current market flexographic plate-loading machines is segmented into:
Manual Plate-Loading Machines
Features:
Low investment costs;
Simple structure;
Convenience of maintenance
Applicable to:
Establishment of label printing companies;
Small-batch manufacturers;
Users with limited budgets.
Semi-Automatic Plate-Loading Machines
Features:
Balancing costs and efficiency;
Positioning fast;
Easy to operate.
Applicable to:
Medium label printing plant;
Multi-variety order production companies.
Fully Automatic Plate-Loading Machines
Features:
Automatic positioning;
Automatic data recording;
Quick recall of recurring orders;
Plate loading is more efficient.
Applicable to:
Large label printing enterprises;
High-end label production factories;
The company has a long-term need for automation upgrades.
As labor costs continue to rise, more and more companies are turning to automation as an important factor in procurement.
Focus on operational agility.
An excellent board loader requires not only high accuracy but also ease of operation.
If the operation of the equipment is complex and new employees require lengthy training, this can have a negative impact on productivity. When shopping, it is recommended to focus on the following:
Is the user interface intuitive?
Is parameter setting simple?
How fast is the slab changeover?
Does it support data saving?
Do you support historical order retrieval?
For label printers with a wide range of orders, a good user experience can improve productivity.
Sixth: Evaluate equipment stability.
Plate installers are long-used devices.
Many enterprises focus on price and neglect the stability of equipment when purchasing.
In fact, a stable operating machine can reduce downtime and maintenance costs.
It is recommended to focus on:
Is the frame strong?
Is the guide rail system made up of high-precision components?
Camera system branding and longevity?
How reliable is the electrical system?
Continuity of operation capability equipment.
For label printing companies with large annual output, equipment stability is often more important than the initial purchase price.
Seventh: Emphasis on after-sales service capability.
Plate mounting machine is a kind of special equipment.
The ability of suppliers to provide technical support in a timely manner following the delivery of equipment is equally important.
In selecting suppliers, it is recommended that the following be considered:
Are on-site installation trainings available?
Do they provide remote technical support?
Do they have spare parts in stock?
Do they have a professional after-sales service team?
Is their response time timely?
A complete aftermarket system can help enterprises to quickly resume production and reduce losses caused by equipment failures.
Tips for Tag Printers to Buy a Sticker
Based on our experience serving a wide range of label printing customers, devices should be selected based on the company's actual needs, rather than simply seeking the highest possible configuration.
General Recommendations:
Start-ups should prioritise cost-effective equipment;
Medium enterprises should give priority to CCD vision positioning systems;
High-end label manufacturers should give priority to the selection of high precision automatic veneers;
Companies with future expansion plans should opt for upgradeable platforms.
Only equipment that meets production needs can truly achieve investment value.
Conclusion:
For label printing houses, flexographic printing plate mounting machines is not only an auxiliary equipment, but also an important tool to ensure printing quality and improve production efficiency.
In the purchasing process, enterprises should pay attention to key factors such as plate installation accuracy, vision positioning system, automation degree, equipment stability and after-sales service. By scientifically assessing their own production needs and selecting suitable plate assembly machines, enterprises can effectively reduce material waste, shorten changeover time and create higher production efficiency and market competitiveness.
