3D printing the Woodburytype – Plastic printing the plate or gel printing the image? (2020)
Conference Proceeding
Leech, D., Guy, W., & Klein, S. (in press). 3D printing the Woodburytype – Plastic printing the plate or gel printing the image?

The Woodburytype process is one of the only printing processes capable of producing continuous tone. It is a 2.5D process that produces a textured relief print from a gelatin-based ink that contains no photo-active element and therefore does not degr...

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.

The polychromatic Woodburytype: Colour tracking in translucent, patterned gelatin/pigment films (2020)
Journal Article
Leech, D. J., Guy, W., & Klein, S. (2020). The polychromatic Woodburytype: Colour tracking in translucent, patterned gelatin/pigment films. Molecules, 25(11), Article 2468. https://doi.org/10.3390/molecules25112468

The Woodburytype is a 19th century photomechanical technique capable of producing high-quality continuous-tone prints. It uses pigment dispersed in gelatin to produce a 2.5D print, in which the effect of varying tone is produced by a variation in the...

Woodburytype: A historical process resurrected by modern methods (2020)
Journal Article
Klein, S., Guy, W., Leech, D., & Argyle, J. (2020). Woodburytype: A historical process resurrected by modern methods. IMPACT Printmaking Journal,

One of the technological achievements of the 19th century was the mass reproduction of photographic images. Woodburytype was the first commercially successful photomechanical continuous tone printing method, of unsurpassed quality until today. Along...

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 optical properties of the Woodburytype - An alternative printing technique based on a gelatine/pigment matrix (2020)
Journal Article
Leech, D., Guy, W., & Klein, S. (2020). The optical properties of the Woodburytype - An alternative printing technique based on a gelatine/pigment matrix. Journal of Physics Communications, 4(1), Article 015018. https://doi.org/10.1088/2399-6528/ab6ed4

The Woodburytype is a 19th century photomechanical printing method, producing high-quality continuous-tone images that use a suspension of carbon black in gelatine as a relief print, in which the variation in height of the print produces the grayscal...
