1.Core Advantages of Stacked Structure: Precision and Efficiency in Synchronization
With a modular stacked unit structure, stack printing machine can easily realize double sided printing and four color overprinting. Each printing unit supports independent control over ink supply and registration, and works with a high precision anilox roller ink transfer system. Such a design guarantees even color distribution and natural color transition during production. The overprint accuracy stays stably within ±0.15 mm, which greatly upgrades printing quality and product consistency. It also effectively shortens the debugging cycle and helps achieve fast and stable production capacity release.
2.Double Pneumatic Loading and Unloading System: Stable Material Control for Easier Operation
Upgraded with a double pneumatic loading and unloading device, combined with switchable pneumatic shafts and a fully automatic tension control and deviation correction system, the machine is widely compatible with a wide range of substrates, from thin paper to thick cardboard, and from plastic films to special materials. The system monitors the material status in real time and automatically adjusts tension, significantly reducing issues such as wrinkling and deviation, and guaranteeing continuous and stable material feeding.
3.Integrated Full Surface Coating: Flexible Process Expansion
The Stack Flexo Printing Machine 4 Color integrates a full surface coating unit, enabling primer coating, color enhancement, glazing and scratch resistant treatment without external auxiliary equipment, thus saving equipment investment and workshop space. The coating thickness can be precisely regulated. Combined with eco friendly inks and coatings, it easily achieves diverse surface effects such as matte, glossy and tactile finishes. Printing and post processing are completed in one stop, shortening the production cycle and providing richer texture solutions for the packaging and labeling industries.
4. Enhanced Corona Treatment: Upgraded Ink Adhesion
Built with a high efficiency corona treatment device, Stack type flexo press performs high energy treatment on the surface of substrates such as plastic films, significantly improving their surface tension and thoroughly enhancing the adhesion performance of inks and coatings. It fundamentally solves problems such as ink detachment and fading after printing, making printed products more friction resistant and weather resistant for long lasting performance. This function is especially suitable for common plastic materials including PE, PP and PET, expanding the equipment’s application potential in flexible packaging, film labeling and other fields.
5. Eco-Friendly Design for Low-Carbon Production
Featuring an eco-friendly water-based ink system, Stack Type Flexo Printing Machine releases no harmful solvents whatsoever. It fully complies with national green printing standards and food packaging safety regulations. This makes it perfectly suited for high-environmental-requirement scenarios like plastic packaging, while also protecting the production environment and safeguarding the health of operators.
On top of that, its optimized body structure and power system enable the equipment to run with low energy consumption. The machine is also equipped with an ink circulation and recovery device, which helps cut down on ink waste and reduce pollutant discharge effectively.

Comprehensive Services: Safeguarding Customers’ Production
Adhering to the philosophy of “service oriented”, we have built a full process service system covering pre sales, in sales and after sales stages. In the pre sales stage, we provide one on one consulting services and customize exclusive equipment configuration plans according to customers’ production scenarios and material requirements. During the in sales stage, we arrange technicians to conduct on site installation and debugging, and carry out synchronous operation training to ensure that customers’ teams quickly master the equipment operation skills. For after sales, we have established a 24 hour response mechanism to promptly solve equipment problems during customers’ production, minimize downtime losses and support customers’ efficient production.

We strictly control production quality, implementing standardized management for every procedure from core component processing to complete machine assembly and debugging, ensuring stable performance and reliable quality for each piece of equipment. This stack flexographic printing machine 4 color has obtained multiple authoritative certifications and is widely used by customers in packaging, labeling, paper and other industries. In the future, we will continue to uphold the philosophy of “quality as the foundation and innovation as the soul”, iterate on technologies and products, deepen the ecological construction of the printing industry, and work hand in hand with customers for win-win cooperation to create a new future for the printing industry.
