A different and fascinating approach to the term them of Nature. Based on an interest in Brian Nash, Artist, and experience with Linocuts, Jonathan demonstrated how the different parts (bark, cambium, sapwood, heartwood and pith) can produce an image when treated as a printing block.

Using a cross section of a tree (branch or small tree) as the starting point for the “printing block”; in the demo a young cross section of a Kauri was used; the surface was cleared of chainsaw marks. The options to “face off” were sanding, router in a sledge or mounted on the lathe (against a face plate using double sided tape, glue or pressure from the tailstock) and once smooth the surface is burnt using a gas torch. The charred surface is carefully using a Japanese wood brush, Uzukuri. Jonathan had one such brush and had made his own. The brush is firm but soft ensuring only the burnt carbon is removed and the surface is not marked. The “homemade” brushes used cordage wrapped in masking, duct tape to achieve a stiff handle.



The next step was to apply a coat lacquer to stop the absorption of the Block Printing Ink. They are either water based or oil bases. Water based are easier for cleaning up. The ink comes in a range of colours and depending on the colour of the paper being used is the choice of ink colour. Samples printed on white and black paper clearly showed the benefit of choosing the right colour paper. The ink colour, of choice, is extruded onto a tray and spread out with a Brayer, a 20mm roller made of a hard rubber. The ink was roller many times to ensure consistency.



The ink is then rolled onto the surface of the wood you have prepared. The open time is around 20minutes. The paper is carefully laid down in the wood, working from one end. The paper is pressed onto the wood using a baren to ensure that an inked design is transferred to a paper surface evenly and clearly without the need for a printing press. Traditional barens were often bamboo-sheathed flat pads of wood or hardened paper pulp whilst modern ones can be plastic with a more ergonomic handle.


The pad is used to smoothly apply pressure to the back of the paper with a gentle circular motion to increase the contact between the surface and the inked design so that a good, clean print is achieved. You can carefully peel the paper back and if needed more ink can be added.

The quality of the paper affects the result. Paper for block printing, ds on whether you’re printing a final piece or practicing. For practice, lightweight papers like computer paper or newsprint are suitable. For final prints, consider archival papers like those used for fine art prints, with a weight of 170-200gsm for a good balance of durability and print quality.
