This is a configuration decision page for converters writing an RFQ — not a definition blog. One-line rule: CI = architecture (web support); gearless = drive (how stations sync). You pick both. Full buying path: CI Flexo Buying Guide. Cost drivers (no list USD): price guide.
| Your constraint | Typical recommendation |
|---|---|
| Thin PE / BOPP multi-color film | CI architecture first — then choose gear / servo / gearless by budget & SKU mix |
| CapEx-tight · long stable SKUs | Gear-driven CI (often 6-color) — do not buy gearless “instead of” CI |
| Frequent changeovers · higher usable speed | Servo or full gearless CI — architecture + drive together |
| White / varnish / spots weekly | 8-color CI + drive class matched to mix — see 6 vs 8 |

Stop Asking “Gearless or CI?” — Ask This Instead
Sales language treats them as rival products. Engineering treats them as two RFQ lines:
| RFQ line | Options | Decides |
|---|---|---|
| 1. Architecture | CI · Stack · Inline | Film register / web support — CI vs stack |
| 2. Drive | Gear-driven · Servo · Full gearless | CapEx band, changeover agility, register automation headroom |
Correct RFQ question: “For our substrate and SKU mix, do we need CI? If yes, which drive band — gear, servo, or full gearless — fits budget and changeover frequency?” Beginner definitions: what is a CI flexo press.
Budget — CapEx Bands That Actually Change the Spec
There is no universal list price. Drive class is one CapEx lever among width, colors, usable-speed class, drying and register automation. Use bands — not catalog USD — to keep quotes comparable.
| Budget posture | What to specify | What not to do |
|---|---|---|
| Low CapEx · film still required | CI architecture + gear-driven (or entry servo) · fewer colors · honest usable-speed band | Do not drop CI for a “cheap gearless stack” if thin PE register is the job |
| Medium CapEx · mainstream film converter | 6-color CI + servo (or gearless if changeovers dominate) · dryers sized to usable m/min | Do not pay for full gearless while under-sizing drying — waste moves to solvent / blocking |
| High CapEx · short–medium runs + speed | Full gearless CI · auto-register · matched tunnel / interstation · 6 or 8 by artwork reality | Do not compare sticker prices across unlike drive + drying scopes |
TCO note: Gearless raises CapEx; it can cut OpEx on plants that change jobs often (startup waste, register time). Gear-driven CI often wins TCO when SKUs stay stable for long runs. Model both — do not default to the highest brochure drive.
RFQ cost factors: CI flexo printing machine price.
Materials — Substrate Decides Architecture First
Drive class cannot fix the wrong web path. For stretchy film, CI is the architecture decision; gearless is optional after that.
| Material | Architecture | Drive tendency |
|---|---|---|
| PE (stretchy) | CI strongly preferred for multi-color | Gear OK if long runs; servo/gearless when SKUs change often + tension/register automation matter — PE guide |
| BOPP (thin retail/snack) | CI default for production film | Heat + drying + tension set usable speed; drive upgrades help changeovers — BOPP guide |
| PET / more stable film | CI still common; stack may appear on simpler jobs | Drive class follows run-length mix more than stretch physics |
| Paper / board / opportunistic | Stack or inline may fit; CI not automatic | “Gearless” alone is not a reason to skip architecture fit |
Buyer trap: Buying a gearless non-CI press hoping it will “register like CI” on thin PE. Gearless helps sync; it does not replace continuous drum support.
Color Count — How 4 / 6 / 8 Interacts with Drive
Color stations are a separate CapEx lever from drive. More colors ≠ automatic need for gearless — but more stations raise changeover minutes and dryer load, which is when electronic drive starts to pay back.
| Colors | When it fits | Drive pairing (on CI film work) |
|---|---|---|
| 4-color CI | Simple process / limited spots; CapEx-first entry film line | Usually gear-driven CI; gearless rarely justified unless plant standardizes on one drive platform |
| 6-color CI | Mainstream flexible packaging — process + limited spots | Gear for stable long runs; servo or gearless when weekly SKU swaps / usable-speed targets rise |
| 8-color CI | White / varnish / extra spots are weekly — not idle headroom | Servo / full gearless more often justified — more stations to wash, sleeve and register each changeover |
Decision depth for station count: 6 color vs 8 color CI how to choose. Count separations on the worst recurring SKU, then pick drive.
Use Scenarios — Parameter → Recommendation
Industry-style patterns for RFQs — not a claim that one brand wins every plant. Match your mix, then open product pages.
Scenario A — CapEx-first PE bags
Inputs: PE film · multi-color · longish runs · tight CapEx · changeovers not frantic.
Recommend: Gear-driven (or entry servo) CI, typically 6-color. Architecture solves register; skip full gearless until SKU churn rises. Example explore: 6-color CI.
Scenario B — BOPP snack / retail · mixed SKUs
Inputs: Thin BOPP · process + spots · weekly artwork changes · usable target in a mid speed band (e.g. around 300–350 maps inside King ≤350 — never treat 300 as the King ceiling).
Recommend: CI + servo or gearless, 6-color unless white/varnish is weekly. Size drying with usable m/min — see speed bands.
Scenario C — Premium film · white / varnish weekly
Inputs: Film packaging · 7–8 separations routine · short–medium runs · register waste hurts margin.
Recommend: Full servo gearless 8-color CI — architecture + drive + stations together. Explore: 8-color full servo gearless CI. Confirm dryer capacity before chasing brochure max.
Scenario D — “We were quoted a gearless press” (architecture unclear)
Inputs: Vendor says gearless; substrate is thin PE; quote omits CI / stack / inline.
Recommend: Force the architecture line on the RFQ. For stretchy multi-color film, require CI, then negotiate gear vs gearless. A gearless stack is not a substitute for CI on that job mix.
Scenario E — Ultra-long stable SKUs (process compare)
Inputs: Few SKUs · very high volume · cylinder economics may dominate.
Recommend: Re-check CI flexo vs rotogravure before over-specifying gearless CI. Drive class is secondary to process choice here.
Config Matrix — Architecture × Drive (Film Focus)
| Configuration | Best-fit use | Budget signal |
|---|---|---|
| Gear-driven CI | Film register needed; stable SKUs; CapEx discipline | Lower drive band |
| Servo CI | Film CI + stronger auto-register without max gearless CapEx | Mid drive band |
| Full gearless CI | Film CI + frequent repeats / higher usable-speed ambition | Higher drive band |
| Gearless stack / non-CI | Only if architecture fits substrate — not a PE multi-color shortcut | May look cheaper; wrong web path costs waste |
RFQ Checklist — Force Both Lines
- Substrate family + gauge range (PE / BOPP / PET / …)
- Architecture required: CI / stack / inline — written explicitly
- Drive band: gear-driven / servo / full gearless
- Color count from worst recurring SKU (not aspiration)
- Target usable m/min + ink system (solvent / water) — not brochure max alone
- Changeover frequency (SKU/day or jobs/week)
- Web width and drying / register package scope
- Like-for-like quote rule: same architecture + drive + dryer scope before comparing stickers

Buyer FAQ
For PE film on a limited budget, should I buy gearless or CI?
Buy CI first. On a limited budget, specify gear-driven (or entry servo) CI — not gearless instead of CI. Gearless is a later CapEx step when changeovers and usable-speed targets justify it.
Does 8-color always need gearless?
No. 8-color is about separations (white/varnish/spots). Gearless is about drive. They often travel together on high-mix film lines because changeover load rises with stations — but long, stable 8-color work can still run on a lower drive band if CapEx demands it.
Is gearless CI worth it for long-run BOPP?
Often not as the first upgrade. If SKUs are stable, prioritize CI + drying/tension for usable meters. Gearless pays more when repeats and changeovers dominate the week.
Can a CI press be gearless?
Yes — full servo gearless CI is a standard high-performance film configuration. Architecture and drive are combined, not swapped.
What do I send for a configuration quote?
Substrate, width, colors, usable-speed target, ink type, changeover frequency, and whether you require CI + which drive band. Then use the buying guide and configuration quotation form.
Next Step — Lock Specs, Then Quote
You should now be able to write: architecture = CI (or not) · drive = gear / servo / gearless · colors = 4 / 6 / 8 · substrate and usable speed. That is enough to compare like-for-like quotes.

King Series
Based on your profile: Flexible packaging · Film, BOPP, PET, PE · 1000–1300mm · 350m/min
King Series is the strongest fit for Flexible packaging because Best fit when the plant runs high-speed film jobs and needs reliable register control, fast ramp-up, and strong production stability. At your target speed of 350m/min, this platform keeps register stable, startup waste low, and changeovers practical for repeat jobs.
You selected Film, BOPP, PET, PE. King Series is engineered for thin film, BOPP, PET, PE. Core substrate window: thin film, BOPP, PET, PE. This reduces tension surprises and ink-transfer issues on your primary material.
Width target 1000–1300mm and speed 350m/min sit inside the King Series envelope (1000-1300mm, 300m/min). Budget Mid to high range and High automation align with very high-automation workflows at this output level.
Key advantages: Servo gear precision; low startup waste; strong register at speed. Tradeoff to confirm: Higher initial investment than Master or Honor, and not the primary choice for FFS heavy-duty sacks. If your mix shifts toward ultra-thin film at 400–500 m/min, compare with another LISHG line before finalizing.
