BUYER GUIDE · FLEXOGRAPHIC PRINTING

How Do You Choose the Right Flexographic Printing Machine?

The right flexographic printing machine should be selected from your actual production requirements—not simply from the highest machine speed. Substrate, printing width, color count, usable production speed, press structure, drying and automation determine whether a machine will deliver stable commercial output.

AT A GLANCE

Check These 6 Parameters First

  • Substrate and material thickness

  • Printing width and color count

  • Required usable production speed

  • CI, gearless or stack structure

  • Drying and web-tension requirements

  • Automation and future production growth

SHORT ANSWER

What Should You Look at When Buying a Flexographic Printing Machine?

Start with the production job rather than the machine model. Define the substrate, thickness, printing width, colors, ink system and target usable speed. Then compare CI, gearless CI and stack configurations according to the production environment.

The key distinction is between maximum mechanical speed and actual production speed. A press rated for a higher speed is not automatically the better investment if the substrate, drying system or web tension cannot support that speed. LISHG develops flexographic printing solutions across Gearless CI, CI Flexo and Stack Flexo configurations, with machine specifications and configurations customized according to substrate, production requirements and finished-product applications.

BUYING DECISION

What Are the Six Main Factors in Flexo Machine Selection?

01 · SUBSTRATE

Does the Press Match Your Material?

Start with the actual substrate range. Film, paper, nonwoven and woven materials do not behave identically during unwinding, printing and rewinding. Thin films can be more sensitive to tension and web stability, while paper applications require a configuration suited to their stiffness and surface characteristics. Choosing a press without validating the substrate can lead to unstable web handling, lower usable speed and inconsistent print quality.

02 · WIDTH & COLORS

How Wide and How Many Colors Do You Need?

Printing width and color count should come from the actual packaging artwork and finished product. Selecting excessive width or unnecessary printing units can increase investment and operating requirements without creating additional value. LISHG therefore configures printing width and color arrangement around the buyer's actual production requirements rather than forcing every customer into a fixed machine specification.

03 · USABLE SPEED

What Production Speed Can You Actually Sustain?

Do not select a press only by maximum mechanical speed. Actual production speed is affected by substrate stability, ink coverage, drying capacity, tension and register. LISHG provides different machine platforms for different production requirements, allowing the target operating speed to be matched with the press structure, drive system and application rather than treating maximum speed as the only selection criterion.

04 · PRESS STRUCTURE

Should You Choose CI, Gearless CI or Stack?

Press architecture must be tailored to your specific applications and production goals. LISHG’s comprehensive product lineup includes Gearless CI, CI Flexo, and Stack‑Flexo configurations. The Master Series serves as our flagship gearless CI platform, while the King Series delivers gear‑sleeve CI solutions. The Apex and Ultra lines cater to diverse CI production demands, and the Honor Series offers stack‑flexo configurations for applications requiring a stack‑style setup.

05 · DRYING & TENSION

Can the Machine Hold Quality at Your Target Speed?

Drying and web tension can become practical limits before the mechanical speed of the press is reached. Higher web speed reduces drying residence time, while unstable tension can cause register drift, wrinkles or film flutter. Selecting the machine therefore requires evaluation of drying, web handling and target production speed as one integrated system.

06 · AUTOMATION

Will Automation Improve Your Actual Production?

Automation should solve a measurable production problem. Automatic register, servo control, sleeve systems, tension control and other functions can reduce setup time and improve repeatability. The right configuration depends on job-change frequency, production mix and quality requirements rather than simply adding every available option.

SPEED MATCHING

How Do You Match Production Speed to the LISHG Machine Series?

Speed should be treated as a production requirement rather than a standalone machine specification. LISHG's different series are positioned for different operating requirements, and the final machine configuration can be customized according to substrate, printing width, colors, ink system, production target and application.

QUICK SELECTION

What Is the Fastest Way to Choose the Right Flexo Machine?

STEP 01

Define the Production Job

Confirm substrate, thickness, printing width, colors, ink system, finished product and target usable production speed.

STEP 02

Match the Press Architecture

Compare Gearless CI, gear-sleeve CI, and Stack Flexo options, then narrow the selection using speed, application, automation, drying, and investment requirements. The King Series should be considered when a gear-sleeve CI structure production positioning fits the application.

STEP 03

Submit Your Parameters for a Solution

Send the complete production profile to LISHG so the engineering team can evaluate the appropriate series, configuration and optional functions for your application.

FAQ

Flexographic Printing Machine Selection FAQ

What is the most important factor when choosing a flexographic printing machine?

The most important factor is matching the machine configuration to the actual production job. Substrate, width, colors, usable speed, drying, and automation should be evaluated together rather than selecting the machine from one parameter.

Is a higher-speed flexographic printing machine always better?

No. Maximum mechanical speed is only the machine's upper capability. Actual production speed depends on substrate behavior, drying, ink coverage, tension and print-quality requirements. A properly matched machine can provide better production economics than a higher-speed machine that cannot operate efficiently on the actual job.

What is the difference between the Master and King Series?

The Master Series is LISHG's flagship gearless CI platform, while the King Series is a gear-sleeve CI solution. The appropriate choice depends on the required press architecture, production target, substrate, automation requirements, and overall machine configuration.

How many colors should I choose?

Select the color count from the actual artwork and finished product. LISHG can configure the printing solution around the required color arrangement instead of forcing every production application into one fixed configuration.

Can one flexographic printing machine print every substrate?

A machine may support multiple substrates, but the complete material range must be validated before purchase. Different materials can require different tension, drying and web-handling conditions.

Can LISHG recommend a machine based on my production requirements?

Yes. Providing the substrate, thickness, printing width, colors, ink type, target usable speed, finished product and automation requirements allows the engineering team to evaluate the appropriate machine platform and configuration.
