Understanding Linocut Prints

Linocut printing, a variant of woodcutting, is a captivating form of fine art printmaking that utilizes a sheet of linoleum (or ‘lino’) as the relief surface. It traces its origins to the early 20th century, precisely used during the German Expressionist period. Over the years, linocut prints have steadily grown in popularity to become a staple in the realm of graphic arts, primarily due to their distinctive aesthetic and relatively simple learning curve.

The creation process in linocut printing entails cutting into the surface of the lino with a sharp instrument, where the uncarved areas will reveal an inverse (reversed) relief of the intended print. Once the cutting is finalized, ink gets applied to this surface using a roller, and then impressing it onto paper or fabric. The result? You’re gifted with a stunning print that comes off as a mirror image of the carved lino surface.

Essential Equipment for Linocut Prints

Having the right tools at your disposal can utterly transform your linocut printmaking experience. These are some of the core instruments you’d need to venture into linocut printing:

1. Carving Tools: An array of gouges and blades are available, each offering different carving effects. For starters, a basic linocutting set with an assortment of small V-shaped tools, larger U-shaped gouges, and a flat chisel is recommended.

2. Inking Plate: This flat, smooth surface is essential for rolling out your ink before application onto the lino. Glass or perspex plates are most favored due to their easy cleanup.

3. Lino Sheets: The lino is your canvas in the printmaking process. These sheets come in various types, including traditional hessian-backed linoleum and softer, easier to carve substitutes.

4. Printing Press: While linocut printing can be done by hand, a printing press gives you more consistent results, especially for editioning. However, a barren or spoon can also suffice for pressing the paper onto the inked lino.
