Flexographic Printing Press Selection Guide: A Scientific Decision-Making Path for Equipment Selection in Packaging Printing Plants
Practical Guide for Multi-Dimensional Equipment Screening Based on Substrate, Orders, and Operating
Introduction
When packaging printing factories select flexographic printing machines, common‑occurring problems include mismatched machine structures and printing substrates, redundant color‑group configurations, and incompatible transmission modes with order batch‑sizes. Following a standardized decision‑making procedure, this article assists processing plants in selecting suitable models according to raw materials, orders and workshop conditions.
Step 1: Quantify basic production requirements
Before equipment selection, convert business indicators into configuration requirements for the flexographic printing machine.
‑ Statistics of printing substrates: Sort out daily processed materials, record the grammage range of paper, and classify materials such as kraft paper, cardboard, coated paper, non‑woven fabric, composite paper and special‑purpose medical‑grade paper.‑ Statistics of printing parameters: Collect commonly‑used printing width, repeat length of printing plates, number of printing color groups and mainstream operating‑speed range from orders.‑ Production‑capacity calculationTheoretical hourly output = Material‑feeding meters per minute × 60. Work out the required material‑speed range of the machine based on total monthly order volume.‑ Workshop‑condition statistics: Record the length, width, height and power‑supply specifications of the factory building. Reserve space for equipment maintenance and disassembly, and check the overall outer dimensions. Confirm ink types and the proportion of water‑based ink and UV ink.Step 2: Technical classification based on machine structures
Sleeve‑type flexographic printing machine (FM‑TS): Equipped with sleeve‑type plate rollers for quick plate replacement. Full‑servo drive removes pitch‑limit restrictions. Compatible with water‑based and UV inks, it supports online full‑image inspection and pre‑register printing for frequently‑switched multi‑specification orders.
‑ Full‑servo push‑type flexographic printing machine (FM‑FS): Servo‑driven automatic printing‑pressure adjustment and plate‑roller position memory. The turret‑type non‑stop roll‑changing and unloading system adapts to wide‑range coils with grammage from 30‑400 g/m².‑ Petal‑type flexographic printing machine (FM‑CS / FM‑C): Quick‑change petal‑shaped plate‑mounting structure and full‑servo shaft‑less transmission maintain stable over‑printing accuracy during speed adjustment. Ideal for pre‑printing jobs for paper bags, paper cups and carton boxes.‑ Wide‑web pre‑printing flexographic printing machine (FM‑S): Thick cast‑iron frame enables high‑speed operation. Servo‑assisted pre‑registration suits large‑batch carton pre‑printing and milk packaging production.‑ Unit‑type flexographic printing machine (FM‑A / FM‑B): Expandable with online functions including dust removal, corona treatment, die‑cutting and slitting. Closed‑loop tension control and electronic deviation correction adapt to various paper materials and non‑woven fabrics.‑ Frame‑coating flexographic printing machine for medical‑grade packaging (FM‑YL): Integrates printing and reverse‑side frame gluing. It features automatic glue‑concentration control and zone‑based air‑duct temperature control, designed for special‑purpose products such as medical‑glove packages.‑ High‑speed stack‑type flexographic printing machine (FM‑VSP): Space‑saving footprint, independent servo drives and unified drying systems cut energy consumption. It works with paper, film and composite materials.Step 3: Inspection and matching of key parameters
‑ Width inspection: The maximum printing width of orders shall never exceed the maximum allowable feeding width of the machine.
‑ Transmission‑system inspection: For frequent specification‑switching work‑flows, prioritize full‑servo shaft‑less transmission models that break the pitch restriction on printing‑plate repeat lengths.‑ Color‑group configuration inspection: Configure enough color groups to meet the maximum color‑count requirement of orders.‑ Drying‑unit inspection: Deploy suitable drying combinations including hot‑air, infrared or UV drying according to ink categories.‑ Special‑process inspection: Choose dedicated models with frame‑coating functions if reverse‑side gluing for medical packages is required.Step 4: Equipment screening based on‑order composition and production‑site environment
Follow the conditional matching rules below:
‑ Frequent specification changes and high plate‑replacement frequency → Prioritize sleeve‑type or push‑type series of flexographic printing machines;‑ High‑proportion pre‑printing orders for paper bags, paper cups and cartons → Choose petal‑type models;‑ Large‑batch carton pre‑printing and high‑speed‑output demands → Adopt wide‑web pre‑printing models;‑ Integrated online post‑processing such as die‑cutting and slitting is required → Select unit‑type machines;‑ Medical‑packaging jobs with back‑coating procedures → Use the dedicated frame‑coating flexographic printing machine for medical‑grade packaging;‑ Limited workshop space and diverse raw‑material types → Go for compact high‑speed stack‑type models.Conclusion: Quick checklist for equipment selection
Complete four self‑check items before finalizing your machine choice:
The grammage and categories of printing substrates fall within the machine’s material‑adaptable range;
Printing width, plate repeat length and color‑group quantity satisfy peak‑order demands;
The theoretical feeding speed matches production‑capacity requirements;
Overall machine dimensions and power‑supply conditions are compatible with the factory.
If your business covers multiple substrate types, calculate the proportion of each order category and prioritize the machine suited for your dominant business. For orders with boundary‑limit parameters, evaluate optional customized configurations in combination with long‑term business plans.
