Wall map
A large map designed to be displayed on a wall, often for didactic purposes.
Watermark
An integral design in paper. Best seen with transmitted light.
Woodcut (woodblock)
An image printed in relief from a carved wooden block. The block is carved, with knives and gouges, on the side grain and blank areas are cut away, leaving raised lines which hold the ink and provide the image. This is relief printing.
Wood engraving
The technique of printing from a wooden block that was carved on the end grain. Typical engraving tools, such as the burin, are used and the detail is finer than can be achieved with woodblock technique. Wood engraving is a relief process.
Wove paper
A machine-made paper that is cast on a very fine mesh. On casual inspection one does not see the mesh lines as one does with laid paper. Wove paper came into use in the late 18th century.
