Question
What's the difference between LPI and DPI in lenticular printing?
Answer
Both numbers matter in lenticular printing, but they describe different things: one is the lens, the other is the print.
| Term | What it measures |
|---|---|
| LPI (lenticules per inch) | How many cylindrical lenses fit across an inch of the lens sheet |
| DPI (dots per inch) | The printer's output resolution |
Your interlacing software's LPI setting must match the physical lens exactly, and print DPI should be at least 720 for sharp stripe definition.
