Printing

These are used for removing the wood between the cut lines or colour masses, and should be ordinary carvers' chisels of the following sizes:

Fig 4

When the register marks corresponding to these colour forms have also been cut, and the paper washed off the blocks, the clear spaces may be used for pasting down new key impressions for the smaller colour patches and their corresponding register marks. In this way one side of a colour plank may contain several different colour forms and sets of register marks. As a rule the different colour patches would be printed separately, though in some cases two colours may be printed at one impression if they are small and have the same register marks.

Particular attention must be given to the careful placing of the paper home in the register notches, and to holding it there until the rubber has gripped the paper on the block.

except those under No. 9, which are short-handled chisels for small work.

The Japanese toolmakers fit these small chisels into a split handle as shown in fig. 5. The blade is held tightly in its place by the tapered ferrule when the handle is closed, or can be lengthened by opening the handle and pulling forward the blade in its slot. In this way the blade can be used down to its last inch.

However exactly the register marks may be cut in a new set of blocks, very puzzling errors occasionally arise while printing, especially if the planks are of thin wood.

When the block has been printed on the whole batch, the sheets should be replaced at once between the boards before one prepares for the colour impressions. Usually the paper will be too dry for colour by this time: if this is so, the damping sheets should be moistened and put in again as before; one to each three printing sheets. In a minute or two they will have damped the paper sufficiently and must be taken out, leaving the printing sheets to stand, between the boards, ready for the first colour-block.

This is needed for driving the larger chisels.
