In the field of flexographic printing, CI flexo printing machines and stack type flexo printing machines have formed unique application advantages through differentiated structural designs. With years of experience in R&D and manufacturing of printing equipment, we provide customers with printing solutions that balance stability and innovation by accurately matching diverse production needs. Below is a comprehensive analysis of the characteristics and applicable scenarios of the two types of equipment from dimensions such as material adaptability, process expansion, and core technologies, helping you make a choice more in line with production requirements.
● Video Introduction
1.Core Structural Differences: The Underlying Logic Determining Adaptability and Expansion
● CI flexo printing machines:Adopts a central impression cylinder design, with all printing units arranged in a ring around the core cylinder. The substrate is tightly wrapped around the surface of the central impression cylinder to complete sequential color overprinting. The transmission system ensures operational coordination through precise Gear drive technology, featuring a rigid overall structure and short paper path. This fundamentally reduces unstable factors during printing and guarantees printing stability.
● Machine Details
● stack type flexo printing machines:Centered on independent printing units arranged in upper and lower stacks, each printing unit is linked through gear transmission. The equipment has a compact structure, and printing units can be flexibly configured on one or both sides of the wallboard. The substrate changes its transmission path through guide rollers, inherently offering double-sided printing advantages.

2.Material Adaptability: Covering Diverse Production Needs
CI Flexo Printing Machines:High-precision adaptation to multiple materials, especially overcoming difficult-to-print materials.
● Wide adaptation range, capable of stably printing paper, plastic films (PE, PP, etc.), aluminum foil, woven bags, kraft paper, and other materials, with low requirements for material surface smoothness.
● Excellent performance in handling thin materials with high flexibility (such as PE films). The central impression cylinder design controls substrate tension fluctuation within an extremely small range, avoiding material stretching and deformation.
● Supports printing of 20–400 gsm paper and cardboard, demonstrating strong material compatibility in wide-width corrugated pre-printing and flexible packaging film printing.

Stack Flexo Press: Convenient, Flexible for Diversified Production
The Stack Type Flexographic Printing Press offers ease of use and flexibility, adapting to diverse production requirements:
● It delivers overprinting precision of around ±0.15mm, suitable for medium to low-precision single-sided multi-color printing.
● Through humanized design and intelligent control systems, equipment operation becomes more user-friendly. Operators can easily complete startup, shutdown, parameter adjustment, and other operations via a concise interface, enabling quick mastery even for novices and significantly reducing enterprise operational thresholds and training costs.
● Supports quick plate changing and color unit adjustment. During production, operators can complete plate replacement or color unit adjustment in a short time, reducing downtime and improving production efficiency.

3.Process Expandability: From Basic Printing to Composite Processing Capabilities
CI Flexo Press: High-Speed, Precision-Driven Efficient Production
The CI Flexographic Printing press stands out for its speed and precision, enabling streamlined, high-efficiency production:
● It reaches printing speeds of 200–350 meters per minute, with overprinting accuracy of up to ±0.1mm. This meets the needs of printing large-area, wide-width color blocks and fine text/graphics.
● Equipped with an intelligent temperature control module and automatic tension control system. During operation, it automatically adjusts substrate tension accurately based on material properties and printing speed, keeping material transfer stable.
● Even during high-speed printing or when handling different materials, it maintains consistent tension. This avoids problems like material stretching, deformation, or overprinting errors caused by tension fluctuations—ensuring reliable high precision and stable printing results.
Stack Type flexo printing machines: Flexible for Conventional Materials, Focused on Double-Sided Printing
● It works well with mainstream substrates like paper, aluminum foil, and films. It’s particularly suited for high-volume printing of conventional materials with fixed patterns.
● Double-sided printing is achievable by adjusting the material transfer path. This makes it ideal for packaging materials that need graphics or text on both sides—such as handbags and food packaging boxes.
● For non-absorbent materials (like films and aluminum foil), special water-based inks are required to ensure ink adhesion. The machine is more suitable for processing materials with medium to low precision demands.
4.Full-Process Technical Support to Take the Stress Out of Production
In addition to the performance advantages of the flexo printing equipment itself, we provide customers with comprehensive service support and integrate environmental protection concepts into the entire production process to help customers achieve sustainable development.
