Step up to a serious UV printer and you will encounter three industrial printheads again and again: the Ricoh Gen5i, the Konica KM1024i and the Starfire SG1024. All three are proven, high-performance heads used in quality UV flatbed and roll-to-roll machines, and all three cost real money. So which is best? The honest answer is that it depends on your speed, quality and budget priorities — and this guide compares them head to head so you can decide with confidence.

Each head has a distinct personality: the Gen5i is the quality specialist, the KM1024i is the balanced production workhorse, and the Starfire SG1024 is the heavy-deposition industrial powerhouse.
Ricoh Gen5i: The Quality Specialist
The Ricoh Gen5i has fewer nozzles (360) but fires them with exceptional precision and a fine variable droplet, giving it superb gradation and fine detail. It is the head of choice where image quality matters most — premium display graphics, photographic reproduction, fine text and high-end retail work. Its 300–600 npi-class resolution and refined greyscale make it the “quality” option among the three.
Choose the Gen5i if your UV work competes on image quality and fine detail rather than raw speed.
Konica KM1024i: The Production Workhorse
The Konica KM1024i packs 1,024 nozzles into a wide head, delivering very high throughput with good quality. It is the balanced performer — fast enough for serious production, with variable droplet for respectable image quality. This combination of speed, quality and relative affordability has made it one of the most widely used heads in UV and high-speed solvent machines in India.
Choose the KM1024i if you need high-volume output with solid quality at a competitive price.
Starfire SG1024: The Industrial Powerhouse
The Starfire SG1024 (from Dimatix/Fujifilm) is a 1,024-nozzle head built for high ink deposition and rugged industrial duty. It excels where you need to lay down a lot of ink fast — heavy white coverage, varnish, textured effects and demanding production environments. It is a premium head, priced accordingly, and is often found in industrial UV machines built for heavy, continuous output.
Choose the SG1024 if you need heavy ink deposition, robust industrial reliability and top-tier production throughput.
Speed and Productivity Compared
- Gen5i: high speed with an emphasis on quality; excellent for quality-focused production.
- KM1024i: very high speed across a wide swath; the productivity sweet spot.
- SG1024: very high speed with heavy deposition; built for demanding industrial volume.
All three are fast by any standard. The difference is in how they balance speed against quality and ink load — and therefore which suits your specific output.
Image Quality Compared
For fine detail and smooth gradients, the Gen5i leads, thanks to its fine droplet and high effective resolution. The KM1024i delivers very good quality with excellent speed. The SG1024 prioritises deposition and durability; it produces strong, bold output and excels at heavy coverage, though the Gen5i edges it on delicate photographic gradation. Match the head to the quality your customers actually pay for.
Price in India
| Printhead | Indicative Price (ex-GST) | Value Position |
|---|---|---|
| Konica KM1024i | ₹85,000 – ₹1,40,000 | Best speed-per-rupee |
| Ricoh Gen5i | ₹90,000 – ₹1,50,000 | Quality premium |
| Starfire SG1024 | ₹1,20,000 – ₹2,00,000+ | Industrial premium |
Because UV machines use multiple heads, these prices multiply across the carriage — making the choice a significant part of both machine cost and long-term replacement cost. The KM1024i typically offers the best balance of performance and price; the Gen5i and SG1024 command premiums for their specific strengths.
Which One Should You Choose?
- Premium quality and fine detail: Ricoh Gen5i.
- High-volume production at competitive cost: Konica KM1024i.
- Heavy ink deposition and industrial duty: Starfire SG1024.
- Balanced speed and quality: Konica KM1024i.
- White/varnish-heavy or textured work: Starfire SG1024 or Ricoh Gen5i.
Lifespan and Maintenance
All three are industrial heads built for long service — typically 2 to 4+ years in production with proper ink, filtration and daily maintenance. UV ink cures quickly, so consistent care and correct capping are essential for every one of them. The higher-value heads (Gen5i, SG1024) reward disciplined maintenance most, since replacement is costlier. Whichever you choose, buy genuine and maintain it well to protect the investment.

Ink Deposition and Coverage Compared
A head’s ability to lay down ink defines what it can produce. The Starfire SG1024 excels at heavy deposition — laying down thick, opaque layers fast, which is why it is favoured for heavy white coverage, varnish and textured effects. The Konica KM1024i balances good deposition with speed for general production. The Ricoh Gen5i prioritises fine, controlled droplets for detail rather than sheer volume of ink. If your work demands bold, opaque, heavy-ink output, deposition capability should weigh heavily in your choice.
Which Head for Which UV Application
- Premium display and photographic UV: Ricoh Gen5i — finest detail and gradation.
- High-volume signage and general UV: Konica KM1024i — speed and value.
- Heavy white, varnish and textured effects: Starfire SG1024 — heavy deposition.
- Industrial décor and packaging: KM1024i or SG1024 — production throughput.
- Close-viewed retail and awards: Gen5i — quality that shows up close.
Match the head’s strength to your dominant output, not to brand preference.
Multi-Head Configurations and Carriage Design
UV machines mount multiple heads for colour, white and varnish channels. The head you choose shapes the carriage: the wide KM1024i and SG1024 need fewer heads for coverage, while the compact Gen5i may be used in greater numbers for the same swath. More heads mean more speed and more channels but also higher cost and more maintenance points. When comparing machines, look at the whole head configuration — count, arrangement and channels — because that determines real capability far more than the head model alone.
Maintenance Across the Three Heads
All three are industrial heads that reward disciplined care, but the higher-value heads demand more attention to protect the investment. Use recommended, filtered UV ink on all of them; run daily nozzle checks; cap properly every day; and keep the workshop clean. UV ink cures fast, so an idle or uncapped head clogs quickly regardless of model. The SG1024 and Gen5i, being costlier to replace, make consistent maintenance especially important — a small daily routine protects a large investment.
Total Cost of Ownership Compared
Look beyond the sticker. Over a machine’s life, your costs include the heads themselves (multiplied across the carriage), ink, maintenance consumables, labour and — critically — downtime. The KM1024i typically offers the lowest total cost for balanced production. The Gen5i adds a quality premium that pays back in premium work. The SG1024 carries the highest cost but delivers industrial deposition and durability that demanding operations need. Choose on total cost relative to the revenue each head enables, not on head price alone.
More Industrial Head Questions
Can a machine mix different head brands?
Generally no — machines are engineered around one head family’s electronics and carriage. You choose the head platform when you buy the machine.
Which head is easiest to get spares for in India?
The Konica KM1024i and Ricoh Gen5i are widely used and well supported, so genuine spares are readily available. Confirm SG1024 availability with your supplier.
Which is best for white ink?
The Starfire SG1024 excels at heavy white deposition; the Ricoh Gen5i handles white with fine control. Choose based on whether you need heavy coverage or fine white detail.
Making the Decision: A Practical Framework
Faced with three excellent industrial heads, buyers can overthink the choice. Here is a simple framework. First, identify your dominant output: is it fine-detail premium work, high-volume general production, or heavy-ink industrial applications? Second, identify your real constraint: is it speed, quality, or budget? Third, match the head whose strength addresses that constraint. If quality on close-viewed premium work wins your contracts, the Ricoh Gen5i is your head. If you need maximum throughput at a competitive cost, the Konica KM1024i is the balanced choice. If your work demands heavy white, varnish or textured deposition in an industrial setting, the Starfire SG1024 delivers what the others cannot. Most buyers, once they answer those three questions honestly, find the decision makes itself.
It also helps to remember that all three are genuine, proven industrial heads with good support in India. You are not choosing between good and bad — you are choosing between three strengths. The wrong choice is not picking a lesser head; it is picking a head whose strengths do not match your work, and paying for capability you will never use or falling short on the quality your customers demand.
The Role of the Machine Builder
Even the best printhead underperforms in a poorly built machine. The carriage precision, rail quality, ink delivery system, curing (in UV) and software all determine how well a head actually performs. This is why the machine builder matters as much as the head. A builder who understands the head, tunes the machine properly, and offers genuine spares and responsive support will get far more from a KM1024i than a poor builder gets from an SG1024. When you invest in an industrial UV printer, you are buying the head and the engineering around it together.
For this reason, buy from a manufacturer that builds machines on genuine heads, understands each head’s strengths, and backs the machine with warranty, genuine spare printheads and nationwide technical support. That combination — the right head for your work, in a well-built machine, supported by people who know it — is what turns a significant investment into a reliable, productive asset. Discuss your actual output requirements with an experienced builder, ask to see sample prints on each head option, and let real results on your own work guide the final decision.
Final Word on Choosing Your Industrial UV Head
The Ricoh Gen5i, Konica KM1024i and Starfire SG1024 are all excellent industrial printheads, and choosing between them is about matching strengths to needs rather than finding a single “best” head. The Gen5i rewards quality-focused work with fine detail and smooth gradation. The KM1024i offers the best balance of speed and value for high-volume production. The SG1024 brings heavy industrial deposition for demanding applications. Identify what your business actually produces and what constrains it, and the right head becomes obvious.
Whichever you choose, the machine around it and the support behind it matter just as much as the head itself. A genuine head, in a well-built machine, backed by warranty, spares and responsive technical support, is what turns a major investment into a dependable production asset. Take the decision seriously, look at real sample prints on each option, and buy from a builder who understands these heads and stands behind their machines.
