8-Color Flexo
Printing Machines

The practical difference is configurability. A 6-color machine gives you four CMYK stations plus two additional stations — enough for white base plus one Pantone spot color, or two Pantone spot colors without white base. An 8-color machine gives you four CMYK stations plus four additional stations. This means you can run white base plus CMYK plus three Pantone spot colors in a single pass, or dual white base plus CMYK plus two spot colors on dark substrates, or a full extended gamut configuration with orange, green, and violet inks alongside CMYK. The value is not "more color" — it is the ability to complete complex multi-color jobs in a single pass that would require two passes on a 6-color machine.

Extended gamut printing (also called ECG or expanded gamut) adds orange, green, and violet inks to the standard CMYK set, expanding the printable color range to cover approximately 85–90% of the Pantone color library from a fixed set of inks — without mixing custom Pantone inks for each job. The LQ-8S has eight independently loaded print stations, which is the hardware requirement for ECG printing (CMYK + O + G + V + white base = 8 stations). However, ECG also requires extended gamut ink sets and color management software (RIP) that are separate from the machine. The LQ-8S supports ECG as a production workflow — but the ink system and color management setup must be confirmed with your ink supplier and prepress team before committing to this production model.

You can run dual white base on a 6-color machine — but it consumes two of your six stations, leaving only four stations for the rest of the job. Four stations gives you CMYK only, with no capacity for any Pantone spot colors. If your job requires dual white base plus CMYK plus at least one spot color, a 6-color machine cannot complete it in a single pass. You would need to run the job twice — first pass for dual white base, second pass for CMYK and spot colors — which doubles production time and introduces registration risk between the two passes. On an 8-color machine, dual white base uses two stations and still leaves six stations for CMYK plus two spot colors, all in a single pass.

Two LQ-6CH machines give you 240 m/min combined throughput, the ability to run two jobs simultaneously, operator redundancy, and machine redundancy — if one machine goes down, the other keeps running. One LQ-8S gives you print capability that two 6-color machines cannot match (white base + CMYK + 3 Pantone in a single pass), up to 1200mm substrate width, and half the floor space of two machines. The decision depends on whether you are capacity-constrained or capability-constrained. If your current 6-color line already satisfies all customer print requirements and you simply need more output, buy a second 6-color machine. If you are losing orders because customers require print complexity that your 6-color line cannot deliver in a single pass, buy the 8-color machine.

A full job changeover on the LQ-8S — replacing all eight plates, cleaning eight ink trays and anilox rollers, loading new inks including Pantone spot colors and white base, and re-calibrating registration across eight stations — typically takes 90–150 minutes depending on operator experience and job complexity. This is approximately 30–40% longer than a comparable 6-color changeover. The practical implication is that 8-color economics are most favorable on long continuous runs of the same design. If your production model involves many different designs in short runs with frequent changeovers, the changeover time per job becomes a significant portion of your total machine time and reduces effective utilization. Discuss your typical job mix — number of designs, run length per design, changeover frequency — with LayerQuestar's team when deciding between the LQ-8S and a 6-color alternative.

The LQ-8S is compatible with PE film, PP film, paper (including kraft paper and coated paper), woven polypropylene bags, and non-woven fabric. The machine is a stack-type flexographic printer — it is designed for these substrate types. It is not a CI (central impression) flexo press and is not designed for thin laminated flexible packaging film that requires the precision tension control of a CI architecture. If you are printing on PE or PP bags, paper bags, woven bags, or non-woven fabric, the LQ-8S is the appropriate machine type.

The LQ-1200S machine body is 6,800mm long × 2,500mm wide × 2,900mm high and weighs 6,500 kg. For practical floor planning: allow a minimum 9–10m floor length (machine 6,800mm plus feed and exit clearance), a minimum 4m floor width (machine 2,500mm plus operator clearance on both sides), and a minimum ceiling height of 3.2m (machine height 2,900mm plus service clearance). Floor load capacity must be verified with your facility engineer — 6,500 kg concentrated load requires structural confirmation before ordering. The 600mm, 800mm, and 1000mm models are narrower (1,800mm, 2,000mm, and 2,200mm machine width respectively) and have lower floor load requirements.

EPC is standard on the LQ-8S. At 8 print stations and 120 m/min, active lateral correction is a requirement, not an option. Lateral substrate drift that accumulates across eight stations produces compounding misregistration on the final spot color stations — the stations where Pantone accuracy is most critical. A 0.5mm uncorrected drift at 120 m/min produces 20 meters of defective print in 10 seconds. The hydraulic EPC system continuously monitors and corrects the substrate edge position throughout the run, maintaining registration accuracy across all eight stations from startup to full production speed.
