Varn Regular Fine Powder (uncoated) is a fine, uncoated spray powder for offset printing. It separates freshly printed surfaces and helps reduce ink set-off.
When should you choose this variant?
Match powder to substrate, ink coverage and finishing. Check the stack result instead of increasing powder without control.
- Fine grain: Suitable for lighter-weight substrates when a smooth finish is required.
- No hydrophobic coating: the Regular series suits further printing, coating and lamination.

Selecting particle size based on basis weight
For Regular Fine, start with substrates below 200 g/m² and a 20–30 µm particle range. This does not guarantee suitability for every paper or ink coverage.
Therefore, before switching to a different variant, examine the substrate surface and perform a test run on the actual stock to be used.
How to adjust powdering
- Prepare the equipment according to the manufacturer’s instructions.
- Then, perform a test run using the substrate intended for the job.
- Check powder distribution and sheet protection in the pile.
- Use the lowest dose that effectively limits ink set-off.
Reseal the packaging after use and store it in a dry place. Protect the powder from moisture and contamination.
Questions to consider before purchasing
Does Uncoated refer to uncoated paper?
No. Uncoated describes the powder particles here, not the paper. It does not restrict use to uncoated paper.
Are “Regular Fine” and “CC30” interchangeable?
These are different variants. Regular has uncoated particles; CC30 belongs to the coated series. Test any change under production conditions.
Will powder alone solve every set-off problem?
No. Also check ink drying and stack conditions. Excess powder does not remove the cause of the problem.
Compare anti-set-off powders before changing series. For repeat passes, also consider water-soluble KSL L3.
