What are Newton Rings?
Newton rings are a series of concentric circles centered at the point of contact between a curved (non-flat) and a flat surface (like a touch screen).
There are three common methods to eliminate Newton’s rings in product label overlays:
- Leave an air gap between the product label overlay and the display screen
- Optically bond the product label overlay to the display screen (we typically use adhesive 3M467MPF for this)
- Print very fine clear dots on the back of the window in the graphic overlay
Less Common Methods
There are coated polycarbonates that have a slightly textured back surface considered to be Anti-Newton’s rings coating.
There are also small silicon balls you could spread on top of a display to perform the same function.
Marking Systems prints a pattern of small dots (method number 3 above) to remove Newton Rings.
