Definition
Lines per inch on anilox engraving; higher LPI typically supports finer detail with lower ink volume per cell.
Applications
- Selecting anilox for process vs solids
- Balancing dot gain and coverage
- Fine text reproduction
Benefits
- Enables sharper detail
- Improves highlight control
- Helps manage ink laydown
Industry Examples
- Medical: higher LPI to keep small text crisp for UDI readability.
- Industrial: lower LPI and higher volume for bold solids and dense coverage.
- Electronics: selected to balance opacity and detail when printing high-density warning graphics on ESD films.
FAQ
Q: Does higher LPI always mean better?
A: Not if you need heavy coverage—cell volume must match ink demand.
Q: How do LPI and BCM interact?
A: Higher LPI often pairs with lower BCM for finer prints.
