Involute 01 [mathematical abstract art print, unframed] A4/A3 sizes


Ask a question

Tie a pencil to the end of a piece of string. Now wind the string around a small cylinder one turn and fix the other end. Place the cylinder on a piece of paper and gradually unwind the string, drawing as you go.

You just drew an involute curve. There are an infinite number of such curves, depending on the base shape - in this case a circle.

The curve of an eagle's beak, the dorsal fin of some sharks, some sheep horns and even the tips of some palm fronds display an involute curve. In engineering they are used to shape the teeth of cogs to make gear wheels turn more smoothly.

Try mentally unwinding some shapes for yourself and compare them with the result on paper. Advanced maths with string and pencil!

Designed by David Lawrence, d/dx art prints are created on 315 gsm Canson Infinity Museum Rag produced at the centuries-old Arches paper mill in France. This superb art paper is acid-free and uses no optical brighteners to degrade over time. Ultrachrome K3 inks provide vivid colours which will last without fading for many decades in normal conditions. The robustness of the paper makes DIY framing a simple matter.

The prints are standard European A4 (210*297mm) in size and are unframed. They are packed flat in crystal envelopes with cardboard stiffener and posted in a rigid container via Royal Mail first class.

The colours you are seeing on your monitor are inevitably not precisely the colours you would see if you were looking at the same design in printed form. There is simply no way around that, since the internet places limits on the range of colours that can be displayed and, even if that were not the case, every monitor is subtly (sometimes wildly!) different in the way it displays colours.

But you can be reassured that the quality of our equipment is such that colours and quality are consistent over time and the print you receive will be identical to other prints sold in galleries and art fairs to buyers who have every opportunity to handle and assess them.
