A high-performance CI flexo printing platform for converters needing efficient multi-color packaging production, stable register, and strong output. Balances production performance, operating reliability, and capital investment.

Suitable for flexible packaging converters moving into medium- to high-volume industrial production. Relevant when production throughput and stability are important but the project does not necessarily require the flagship gearless platform.

Depending on model and configuration, supports commonly used flexible packaging films and compatible paper-based substrates. Material thickness, tension characteristics, ink, and drying requirements should be confirmed before selection.

Positioned for high-efficiency production, but actual stable speed depends on substrate, artwork, color coverage, ink, drying, and print-quality requirements. Rated speed should be evaluated together with real saleable output.

Confirm substrate, web width, printing width, color number, target speed, repeat range, production volume, and quality requirements. These factors determine the most appropriate model and specification.

Ultra focuses more strongly on practical mid-speed film and paper production with controlled investment. King is more suitable when higher sustained production capacity and higher-volume packaging output are required.

King focuses on production efficiency and investment balance. Master moves further toward full-servo gearless technology, higher automation, and more demanding precision requirements.

Regular maintenance should cover printing units, drive components, tension systems, anilox rollers, ink systems, drying, electrical systems, and web-handling components. Preventive maintenance helps maintain production stability and register performance.

Apex is our high-performance servo CI flexographic printing platform. It is designed for converters that need stronger production performance, precise control, and stable multi-color printing as their production requirements increase.

Apex is suitable when a standard mid-speed CI press is no longer enough for the planned production target. It is a practical step up when higher performance and servo control have become important but a full-servo gearless platform is not necessarily required.

Servo control gives the printing system more precise control of drive synchronization and machine movement. This helps improve repeatability and supports stable registration during production.

Registration depends on the complete printing system. Servo control works together with web tension, the CI structure, printing pressure, and accurate machine setup. Material characteristics and production conditions also need to be taken into account.

Apex is designed as a higher-performance CI platform, with configurations in the higher-speed production range. The appropriate operating speed should always be determined according to the actual material, print design, drying conditions, and required print quality.

Ultra focuses on practical mid-speed CI production and controlled investment. Apex is intended for customers whose production requirements have moved toward higher performance, speed, and more demanding printing control.

King is primarily about high output, production efficiency, and investment balance. Apex focuses more specifically on high-performance servo CI technology. The right choice depends on whether production throughput or overall servo-CI performance is the main requirement.

Apex provides high-performance servo CI printing. Master uses full-servo gearless technology and is intended for projects where precision, high-speed production, and the highest level of drive control are central to the investment decision.

An upgrade makes sense when production demand has increased, and the limitations of a mid-speed machine are beginning to affect output, registration or production efficiency. We recommend comparing actual production data before deciding that a higher specification is necessary.

The main factors are substrate, web width, number of colors, target production speed, print requirements, and expected production volume. If several materials or job types will be produced, we should review the complete range before final configuration.

Regular inspection should cover the servo system, transmission components, printing units, anilox components, tension control, bearings, drying, electrical systems, and safety devices.

Please send the substrate specification, web width, colors, target speed, expected output, printing requirements, and representative samples or artwork where available. These details help us match the machine configuration to the actual production requirement.

Ultra is our mid-speed CI flexographic printing solution for converters looking for dependable everyday production without moving directly to a higher-end press. The series focuses on practical performance and sensible equipment investment.

Ultra is suitable for converters whose production requirements fit a mid-speed CI platform and who want to keep capital investment under control. It can also be a practical step for companies moving toward CI flexographic printing.

Ultra gives you a practical balance between production capability and investment. It is designed for customers who need reliable CI printing but do not need to pay for a specification that their current production cannot fully utilize.

Ultra is generally designed for the 150–200 m/min production range, depending on the selected configuration. Actual production speed depends on the material, print design, drying conditions and required print quality.

Ultra is more focused on practical mid-speed production and controlled investment. King is intended for higher-output production where additional throughput can make a meaningful difference to operating efficiency.

Apex is the higher-performance option when production speed, servo control and overall printing performance become more demanding. Ultra remains a sensible choice when mid-speed production already meets the required output.

Yes, as long as the different materials and products fall within the selected machine configuration. If you plan to run several material types, we recommend providing the full production range before the machine is configured.

Use your actual production schedule rather than rated machine speed. Working hours, shifts, average running speed, job changes, setup time, maintenance and machine utilization should all be included in the calculation.

Routine maintenance should cover printing units, anilox components, ink systems, drive components, tension control, bearings, drying, electrical systems and safety devices.

Please provide the material, thickness, web width, number of colors, target speed, expected production volume and main product requirements. Current production samples are helpful when determining whether Ultra is the right fit.

MIX is designed around the complete napkin production process, combining flexographic printing with downstream folding and converting. The goal is to produce finished printed napkins through an integrated production line.

MIX is suitable for napkin manufacturers that need to combine printing and converting in one production process. It is particularly useful when finished napkin output, rather than printing alone, is the main production target.

Depending on the selected configuration, MIX can combine printing with processes such as embossing, folding and cutting. The exact configuration is determined by the finished napkin specification.

A napkin line is not only a printing machine. Folding, cutting and other converting processes directly affect the number of finished napkins produced. For this reason, we normally evaluate the complete production flow rather than looking at printing speed alone.

Start with the number of finished napkins you need to produce per day or month. We then consider napkin size, number of plies, folding format, operating hours, job changes and the expected stable production rate.

The most useful information includes napkin size, number of plies, printing colors, folding format, required finished output and raw material specifications. Finished samples or drawings are also helpful.

The machine configuration should be selected according to the required finished napkin dimensions and folding arrangement. We recommend confirming the product specifications before finalizing the equipment.

The printing section prepares the printed material, which then moves through the relevant converting stages. The machine is designed so that these processes work as one production flow rather than requiring separate intermediate handling.

Look beyond the purchase price. Consider intermediate handling, labor, floor space, production continuity, changeovers and finished-product output. An integrated process can be valuable when these factors have a significant effect on daily production.

Maintenance covers both the printing and converting sections. Important areas include printing units, anilox components, ink circulation, web transport, folding and cutting mechanisms, bearings, electrical systems, servo components and safety devices.

Yes. The machine is configured according to the finished product and production requirements. Napkin dimensions, plies, printing colors, folding arrangement, cutting requirements and expected output should be confirmed during the technical discussion.

Please provide your tissue specification, napkin size, number of plies, printing colors, folding format, finished output target and available electrical supply. A finished sample or drawing makes the initial evaluation much more accurate.

Honor Classic is our practical stack flexographic printing solution for converters that need double-sided production without moving directly to a higher-specification servo platform.

It is suitable for customers whose production requirements are straightforward and whose main priorities are dependable stack printing, double-sided capability and controlled equipment investment.

The main advantage is practicality. It provides the core stack printing capability needed for double-sided production without adding higher-level features that may not be necessary for every production environment.

Yes. Double-sided printing is one of the main reasons customers choose the Honor Classic platform. The required color arrangement should be determined from the actual product and artwork.

Honor Classic is designed for production around 100 m/min, depending on the machine configuration and production conditions.

Not always. If your production requirements can be met with a practical stack configuration and the register requirements are within the capability of Honor Classic, moving to a servo platform may not provide enough additional value to justify the investment.

Honor Classic emphasizes practical production and controlled CAPEX. Honor Servo adds servo control for customers who need stronger registration performance and greater production consistency.

Honor Servo Sleeve is designed for customers with more demanding changeover requirements and a high number of SKUs. If job changes are relatively infrequent, Honor Classic may be the more sensible investment.

Honor Classic uses a stack configuration and is well suited to double-sided production. A CI press is generally more appropriate when high-speed continuous printing and central-impression web handling are the main priorities.

Start with the required finished output. We consider working hours, shifts, average running speed, job changes, setup time, maintenance and expected utilization to determine whether the selected configuration provides enough practical capacity.

Routine maintenance should cover printing units, anilox components, ink systems, web tension, bearings, drying, drive components, electrical systems and safety devices. Regular inspection helps keep the machine reliable and consistent over time.

Please provide the substrate, material thickness or paper weight, web width, number of colors, double-sided printing requirements, target speed and expected production volume. Finished samples or artwork are useful when we determine the most suitable configuration.

Honor Servo is a servo-controlled stack flexographic printing machine designed for converters that need reliable double-sided production with stronger registration control and production stability.

Honor Servo is suitable when double-sided printing is an important part of production and registration accuracy needs to be more tightly controlled than a conventional stack press can provide.

The servo system gives the printing units more precise and coordinated control. This helps improve repeatability and supports stable registration during production.

Double-sided printing requires the two printing sides to remain accurately aligned throughout production. Servo control, web tension and proper machine setup work together to maintain this alignment and reduce register variation.

Honor Servo configurations are designed for production around 200 m/min, depending on the selected configuration and production conditions. The actual stable speed should be evaluated against the material, print design and required quality.

Honor Classic focuses on practical stack printing and controlled capital investment. Honor Servo is the step up when stronger registration control, servo operation and production consistency become important.

Both are servo stack platforms. Honor Servo focuses on registration and stable double-sided production, while Honor Servo Sleeve adds a sleeve-based changeover solution for high-SKU production and frequent job changes.

The two press structures suit different production requirements. Honor Servo is particularly useful when double-sided printing and flexible stack production are important. A CI press is generally the better direction when the main requirement is high-speed continuous production.

Look at your actual production problems. If increasing speed, tighter registration requirements or more demanding double-sided work are becoming difficult to manage with the existing setup, Honor Servo may be the appropriate next step.

The answer depends on the final machine configuration and material specifications. Different materials can require different tension, printing pressure, drying and web-handling conditions, so we recommend providing the complete material range before configuration.

Regular maintenance should cover servo motors and drives, register-related components, printing stations, anilox components, ink systems, tension control, bearings, drying, electrical systems and safety devices.

Please provide the substrate, width, number of colors, single- or double-sided requirement, target speed, expected output and register requirements. Your typical job mix and production schedule are also helpful.

Honor Servo Sleeve combines servo-controlled stack flexographic printing with a sleeve system designed to make job changes more efficient. It is intended for production where many different jobs or SKUs make changeover time an important part of overall productivity.

It is a strong fit for converters handling a high number of SKUs and frequent job changes. If your production team spends a significant amount of time preparing the press for the next job, the sleeve system can have a meaningful effect on machine utilization.

The main benefit is easier and faster printing-format changeover. Instead of treating every job change as a long mechanical setup, the sleeve system is designed to simplify the change process and reduce non-printing time.

For long runs, changeover time may be relatively small compared with printing time. For short and medium runs, it can become a much larger part of the production day. Reducing that downtime allows more of the available machine time to be used for actual production.

Yes. High-SKU production is one of the situations where the sleeve configuration can provide the most practical value. The more frequently you move between different jobs, the more important efficient changeover becomes.

We recommend looking at your actual job-change frequency. If you change jobs several times per shift, the saved setup time can be significant. If most jobs run for long periods with few changes, the financial benefit may be smaller.

The two systems solve different production problems. Servo control provides precise and repeatable control during printing, while the sleeve system focuses on making job changes easier. Together, they support both printing stability and production flexibility.

Honor Servo focuses on servo-controlled printing, registration and double-sided production. Honor Servo Sleeve adds the sleeve-based changeover advantage for customers whose production involves a higher frequency of job changes.

Honor Classic is designed around practical stack production and controlled investment. Honor Servo Sleeve is a higher-level solution for customers who also need servo control and faster changeover for a high-mix production environment.

Start with your production mix. If registration and double-sided production are the main requirements and job changes are moderate, Honor Servo may be enough. If frequent SKU changes are reducing machine utilization, the sleeve configuration becomes more attractive.

Sleeves and related mounting components should be kept clean and checked regularly for wear, damage or deformation. The servo system, printing units, anilox components, tension control, bearings and electrical components should also be included in routine maintenance.

Please provide your material, web width, number of colors, typical job length, number of job changes, production volume and double-sided requirements. If sleeve changeover is a major reason for the investment, your current changeover process and frequency are particularly useful for us to evaluate.
