Nova Stack Series: Entry and Mid-Market Bag Production
The Nova stack flexo press series covers two, four, six, and eight color vertical stack configurations for paper bags, courier bags, woven sacks, and light film work. Nova presses prioritize approachable capital cost, compact layout, and maintenance access for converters entering flexo or expanding bag capacity. Typical speeds range from 80 to 150 m/min depending on color count and substrate. The Nova 4-color stack press is the volume seller for shopping bag plants. Nova fits buyers whose register requirements are moderate and job lengths are often short. See stack press buying checklist for specification tips.
Honor Servo Stack: Register Upgrade on Stack Geometry
Honor servo stack presses add electronic line shaft control to stack architecture for faster register recovery and reduced gear maintenance. Available in four, six, and full servo six-color builds, Honor targets plants printing mixed SKUs on bags and film that need better consistency without CI investment. The Honor 6-color full servo stack press suits high-mix operations detailed in full servo stack high-mix jobs. Honor bridges Nova mechanical limits and full CI investment when floor space or budget is not yet ready for a platform change. Servo stack upgrades often pay back within eighteen months for plants running fifteen or more changeovers per shift. Reduced gear maintenance also lowers spare parts spend versus clutch-driven stack lines.
Apex CI Series: Film and Paper Central Impression
Apex CI flexo presses use central impression drums for stable multi-color register on paper, film, and nonwoven. Configurations include four-color paper, six-color film, six-color nonwoven, six-color non-stop film, and eight-color film models. Apex suits flexible packaging converters and paper mills moving from stack or offset outsourcing. The Apex 6-color CI film press anchors most film lamination quotes. Compare CI versus stack trade-offs in CI vs stack guide and film specifics in CI film packaging guide. Apex lines also support dedicated non-stop splicing when converters run extended film campaigns without stopping the impression drum.
King Sleeve CI and Master Gearless Full Servo
King sleeve CI presses combine CI register with sleeve plate change speed for film and paper plants with frequent artwork turnover. Four, six, and eight color film models plus four-color paper configurations are available. Master gearless full servo CI presses represent the top tier: direct servo couples, premium speed up to 500 m/min class, and lowest mechanical backlash for brand packaging. Compare drive philosophies in servo vs gearless article. King fits mid-premium sleeve workflow; Master fits flagship lines audited by global brands.
