Maximum printing speed: 16,000 sheets/hour (the same as UV version) Maximum paper size: 1050×740mm Thickness of substrate: 0.04-1.0mm Supported processes: four-color offset printing, spot color printing, spot glazing, bronzing and priming Applicable products: card boxes, hangtags, instruction manuals, tote bags, ordinary gift boxes, and other large-scale conventional printed materials
Key Takeaways (TL;DR)
- The KBA 6+1 conventional sheet-fed press prints 6 colours plus a coating unit at 16,000 sheets/hour — the workhorse of mainstream carton and commercial work.
- Runs conventional (non-UV) inks on substrates from 0.04 mm to 1.0 mm, including card boxes, hangtags, manuals and tote bags.
- Supports four-colour process, spot colour, spot glazing, bronzing and priming in a single pass.
- It pairs with the UV 8+1 line to give Donghe Industrial both standard-economy and premium-effect capacity.

Conventional offset remains the economic engine of folding-carton and commercial printing: UV is a premium option, but the majority of cartons, tags and manuals still run on conventional inks. In our curated 2026 corpus, folding-carton strategy and label-printers pivoting into cartons were recurring stories, and print automation was a top-ten theme (11 tagged items) — consistent with the push to make mainstream offset lines faster and less labour-intensive.
Editorial Perspective
Our editorial view: a well-maintained conventional 6+1 press is the lowest total-cost route for high-volume, specification-driven work such as pharmaceutical leaflets, instruction manuals and standard gift boxes. It is also the best complement to a UV premium line, letting converters match the finish to the margin.
More FAQ
What does 6+1 mean on a printing press?
6+1 refers to six printing units plus one additional unit used for coating (varnishing or priming). The KBA 6+1 runs conventional inks at 16,000 sheets/hour on folio-format stock.
Conventional ink vs UV ink: what is the difference?
Conventional inks dry by oxidation and absorption, are cheaper and easier to recycle in de-inking, but need drying time or IR/air drying. UV inks cure instantly under UV light, giving faster finishing and scratch resistance at a higher ink and energy cost.
What substrates can a conventional offset press handle?
Typically paper and board from 0.04 mm up to about 1.0 mm on this configuration — coated and uncoated paper, card, folding-carton board and label stock within the 1050×740 mm format.
