LeafcastingMethod is inspired by paper manifacturing principles and it is based on the use of a pulp of natural ﬁbers ﬂoa8ng in water. Advantages: Disadvantages: -‐ totally reversible -‐ less control than manual mending -‐ minimum overlapping -‐ not suitable for all kind of materials (never use for -‐ increasing of paper strength parchment or in presence of water-‐soluble inks or -‐ shorter 8me of execu8on pigments) Leafcaster Pulp blender Pulp measuring
