Printing Techniques
Block printing is a complex technique. Typically six different blocks were used to build up a coloured pattern. Block cutters drew up the design in lamp black on stout wooden blocks. These were up to 3” thick and 18” square. Areas were cut away to leave the design for a particular colour standing in relief and a printing surface formed by hammering in fine flattened brass of copper wires into the grooves in the wood. Pins at the edges of the blocks acted as a register to guide the printer. The pattern repeats had to be skilfully combined to produce the final pattern. In essence, the block was charged on a dye-impregnated blanket, positioned on the cloth, struck with a printer’s mallet of maul, and left to dry. Each colour was applied separately, so the production of a whole cloth or shawl was complicated, requiring great precision. Finally the colours were developed by fixing or steaming, followed by a series of cold and then hot washes.
