Gibsons Fully Interlocking Jigsaw Puzzles
Thursday, October 2nd, 2008Like most jigsaw puzzle manufacturers, Gibsons use an image that has been printed onto a piece of standard european greenboard which is a high density carboard.
The puzzle is cut when a steel die is placed over the image and then up to 500 tons of pressure is applied to ensure a clean sharp cut with no material loss. This process combined with the high density board ensures a minimum of curvature on the puzzle piece where the blade actually comes into contact. Puzzle pieces tend to be small and uniform and it takes a keen eye to see the often subtle differences especially where there are large pieces of the puzzle with the same color such as an area of blue sky. When correctly assembled, fully interlocking puzzles are a very tight fit and the puzzle can be lifted vertically by its corners without the jigsaw puzzle falling apart. The typical puzzle piece is a foursided shape with knobs and indentations. There are many permutations possible such as three knobs and one indentation or two of each, etc. Sometimes by turning the puzzle over it is easier to assemble large areas of a single color as the various puzzle piece shapes tend to stand out.
