Virtually any artwork can be used for puzzle[puzzle?:jigsaw puzzle] making but most major manufactures use lithographic prints because they are high quality, inexpensive, and easily mass produced. Many of the pictures used in puzzles are based on famous photographs or paintings, but some custom puzzle makers let the customer supply their own photographs or pictures.
Backing material of jigsaw puzzle[jigsaw puzzle?:Jigsaw puzzle cutting machine]
Mass market puzzle manufacturers use card-board (also known as chipboard) as a backing material because it is cheap and easy to cut. Higher quality custom-made puzzles still use wood, usually in 5-ply birch. In both cases, adhesive is used to bond the artwork to the backing material.
Cutting equipment[Cutting equipment?:cnc cutting system sample maker] of jigsaw puzzle
The original wood puzzles were cut with jigsaws, also known as scroll saws, and customized wooden puzzles are still made that way today. These saws have a vertical blade that goes up and down through a fixed horizontal table. The puzzle sheet is guided through the blade by hand to cut the desired pieces. The blades used today are very fine, about 0.016 in (0.041 cm) thick. This allows intricate cuts to be made, which take out very little wood, so the puzzles fit together well. It also leaves a very smooth edge surface, with only a minimum of chipping and fuzzing on the back, which can be sanded off. The majority of puzzles today, however, are the cardboard-backed types and these are mass-produced with die cutting equipment.
