Continuous tone relief prints in gelatin – The Woodburytype (2020)
Presentation / Conference
Leech, D., Guy, W., & Klein, S. (2020, July). Continuous tone relief prints in gelatin – The Woodburytype

Since its inception, halftoning has provided us methods of print that have high throughput and are easily reproducible. However, as the complexity of our printing methods increase, we can instead turn our attention to continuous tone methods, where t...

Sources of Pigmentless Colour in Nature – Seashells, Butterflies and Beetles (2020)
Presentation / Conference
Leech, D. (2020, June). Sources of Pigmentless Colour in Nature – Seashells, Butterflies and Beetles

Colour arises most prominently in the world from subtractive processes, such as pigmentation. When light is shone upon a painted wall, for instance, pigment absorbs portions of the electromagnetic spectrum that the material underneath did not and we...

Origins of Colouration in Invertebrates – Pigment and Structure (2020)
Presentation / Conference
Leech, D. (2020, June). Origins of Colouration in Invertebrates – Pigment and Structure. Presented at Field Studies Council Virtual Meet Ups

Colour/pattern recognition is a common cornerstone of animal identification, however, the processes by which animals actually display colour is incredibly complex. Beyond the simple pigmented systems, that also form the basis of our paints and inks,... Read More about Origins of Colouration in Invertebrates – Pigment and Structure.

Continuous Tone Printing from Gel Matrices - The Woodburytype (2020)
Presentation / Conference
Leech, D., Guy, W., & Klein, S. (2020, March). Continuous Tone Printing from Gel Matrices - The Woodburytype

Prevailing print techniques such as inkjet rely on halftoning, a process whereby image tone is approximated by a matrix of droplets varying in density. This, while useful in many applications, ensures a direct link between the resolution and the drop... Read More about Continuous Tone Printing from Gel Matrices - The Woodburytype.

The Physics of Print (2020)
Presentation / Conference
Leech, D. (2020, January). The Physics of Print

And now for something completely different: Woodburytype (2019)
Presentation / Conference
Klein, S., & Leech, D. (2019, April). And now for something completely different: Woodburytype. Presented at British Liquid Crystal Society 2019 Annual Conference, Leeds, England

Woodburytype, invented by Walter B. Woodbury and patented in 1863, was the first commercially successful mechanical printing process for the permanent reproduction of photographic quality pictures and today is still unsurpassed in producing continuou...
