4Ink systems3Dampening modesAvailableExchange
Inking rollers · 4 types
Inking rollers for every ink system.
Choose the roller that matches the ink on your press. Each has its own compound.
Conventional
For oil-based inks
- Short washing times on colour changes
- Constant ink transport, stable colour incl. spot colours
- Dimensionally stable — set once
- Low spoilage, faster to colour at start-up
Combi / mixed mode
Conventional + UV on one press
- One roller set for conventional and UV inks
- Swell-resistant across ink and wash chemistries
- Stable settings after switching
- Less roller inventory, faster changeover
UV
For UV inks and washes
- Resistant to UV inks and washes, minimal swelling
- Long life cycles, fewer roller changes
- Stable on board, plastics and metallised
- Low spoilage, less adjustment
LED-UV / LE-UV
For highly reactive inks
- Built for LED, LE-UV and H-UV inks
- Instant drying, short makeready
- Clean, fast wash-up
- Lower cost per sheet with LED curing
Each inking roller type can have its own page (e.g. /sheet-fed-offset/uv-inking-rollers) for SEO at development stage.
Dampening rollers · 3 modes
IPA, reduced IPA or IPA-free.
A matched dampening set keeps the printing window open when you cut alcohol.
Standard IPA
Printer's challenge
Keeping ink-water balance stable at speed
What our rollers do
- Even water film
- Fast, stable ink-water balance
- Low start-up waste
Reduced IPA
Printer's challenge
Poorer wetting, ink feedback into the pan
What our rollers do
- Water-friendly surface at lower IPA
- Less ink feedback
- Less cleaning
IPA-free
Printer's challenge
Narrow window, emulsification, scumming
What our rollers do
- Matched pan, metering and form rollers
- Wider printing window
- Stable dampening without alcohol
Why cut IPA?Lower consumable cost · safer pressroom (IPA is flammable and harmful to breathe) · lower VOC for brand-owner and food-packaging audits.

Need rollers this week?

FAQ
Sheet-fed questions.
Can't find your answer?
What do you need from me for a quotation?
Your press model, roller positions and quantity, and your ink system. Share a drawing or the old roller's dimensions if you have them. We clarify the rest on a call.
Can one roller set run conventional and UV inks?
Yes. Combi rollers are made for presses that switch between conventional and UV inks, and hold their settings after switching.
Should I re-rubberise or buy press-ready rollers?
It depends on your spindle's condition and how fast you need the press back. We check the spindle first and recommend the right option.

Answers before you ask.
Short answers to what printers and OEMs ask us most.
Ordering & quotes
What do you need for a quotation?
The roller type or machine, dimensions, application and urgency. A drawing, photo or press model helps. We clarify the rest on a call.
Do you supply outside India?
Yes. Sigma supplies across India and has a global presence.
Can you work from a sample instead of a drawing?
Yes — from a drawing, a sample or the press model and roller position.
Exchange programme
Which presses are covered?
Heidelberg, Komori and Ryobi sheet-fed presses, covering the major models.
Is exchange available for other industries?
No. It is for sheet-fed offset presses only. Other industries get new rollers and re-rubberisation.
Re-rubberisation
Re-rubberisation vs press-ready — what's the difference?
Re-rubberisation puts a new cover on your spindle. Press-ready rollers are built new — new spindle, new cover — and arrive fully assembled.
Will you repair my spindle without asking?
No. We check it first and share a report. Repairs only with your approval.
How do you protect the spindle?
SPM rubber removal keeps the metal intact — up to 60% longer spindle life over time than usual industry practice.
Technical support
How does technical support work?
Fill the form, call or WhatsApp us. Our team calls you back to discuss your drawing, then sends a quotation.
Can you identify an unknown roller?
Yes. Share photos, dimensions and the machine, and we help identify it and pick a compound.
