Printing

Next in importance is the preparation of the ink for printing the key-block or any black or grey parts of a design. As a rule the key-block is printed black, more or less diluted with paste; indeed the key-block is often printed very faintly by means of paste only just tinged with a trace of black.

Until one has become quite familiar with the craft of wood-block printing it is not possible to make a satisfactory design for a print, or to understand either the full resources that are available or the limits that are fixed.

The few wood-block prints shown from time to time by the Society of Graver Printers in Colour, and the occasional appearance of a wood-block print in the Graver Section of the International Society's Exhibitions, or in those of the Society of Arts and Crafts, are the outcome of the experiments of a small group of English artists in making prints by the Japanese method, or by methods based on the Japanese practice.

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.

Simple as the process is, there is, from first to last, a long labour involved in planning, cutting and printing, before a satisfactory batch of prints is produced. After several attempts in delegating printing to well-trained pupils I have found it impossible to obtain the best results by that means, but the cutting of the colour-blocks and the clearing of the key-block after the first cutting of the line may well be done by assistant craftsmen.
