Grainy edges, reduction

Note. Forming fabrics too narrow for width of sheet being attempted will accentuate many of the causes of grainy edges. See Feathered and jagged edges.
1. Maintain an even basis weight and use edge bleeds correctly.
2. Check deckles to reduce rollback of flow at the edge.
3. Maintain proper load-to-crown relationship at presses.
4. Keep dryer felts tight and tension even.
5. Dry sheet slowly (gradient drying).
— avoid having early cylinders too hot.
6. Ensure that calender stack is not punching at edges.
