Printing

A set of blocks consists of a key-block and several colour blocks. The block that must be cut first is that which prints the line or "key" of the design. By means of impressions from this key-block the various other blocks for printing the coloured portions of the design are cut. The key-block is the most important of the set of blocks and contains the essential part of the design.

Any colour that can be obtained in a fine dry powder may be used in wood-block printing. Some artists have succeeded in using ordinary water colours sold in tubes, by mixing the colour with the rice paste before printing; but the best results are obtained by the use of pure, finely ground dry colour mixed only with water, the rice paste being added actually on the block.

A print is shown at the end of this book (page 95) as an example of a first experiment in co-operative printing. An actual print was needed to illustrate the method of block printing, and the number required was too great for a single printer to undertake. So the work was divided between four printers (of whom the writer was one), working together. Each of us had been accustomed to print our own prints in small batches of a dozen or two at a time, giving individual care to each print.
