Now you see it, and Now you don’t: Illusive colour (2020)
Presentation / Conference
Klein, S. (2020, November). Now you see it, and Now you don’t: Illusive colour. Presented at Twenty-eighth Color and Imaging Conference, Online

Colour, as beauty, lies in the eye of the beholder. In 1861, based on the RGB model of colour perception, James Clerk Maxwell produced the first colour photographs by exposing black and white film through red, green and blue filters, thus recording i...

The frieze of the Palace of the stuccoes, dated between the 5 th and 6 th century BC, was a polychrome Maya relief discovered in the 1907 in Yucatán, Mexico. It was documented in watercolours and hand tinted photographs by Adela Breton. After years o...

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...

The reconstruction of the appearance of the Acancéh frieze by 2.5D printing (2020)
Conference Proceeding
Klein, S., Trujillo Vazquez, A., Calvet, X. A., & Parraman, C. (in press). The reconstruction of the appearance of the Acancéh frieze by 2.5D printing

The aim of the project is to reconstruct the appearance of the Maya frieze of the Palace of the Stuccoes in Acancéh Yucatán, dating from c. 350 BC to AD 850. The frieze itself is destroyed by now but was documented by Adela Breton in 1907. Her waterc... Read More about The reconstruction of the appearance of the Acancéh frieze by 2.5D printing.

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...

Woodburytype: a forgotten 19th century photomechanical process and its 21st century resurrection (2020)
Presentation / Conference
Klein, S. (2020, June). Woodburytype: a forgotten 19th century photomechanical process and its 21st century resurrection

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...

Rheological and flow birefringence studies of rod-shaped pigment nanoparticle dispersions (2020)
Journal Article
Salamon, P., Geng, Y., Eremin, A., Stannarius, R., Klein, S., & Börzsönyi, T. (2020). Rheological and flow birefringence studies of rod-shaped pigment nanoparticle dispersions. Journal of Molecular Liquids, 313, Article 113401. https://doi.org/10.1016/j.molliq.2020.113401

We study rheological and rheo-optical properties of suspensions of anisometric pigment particles in a non-polar fluid. Different rheological regimes from the dilute regime to an orientationally arrested gel state were characterized and compared with...

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...

Under pressure: An exhibition of printmaking by staff at the University of the West of England, Bristol. (2020)
Exhibition / Performance
Klein, S., Buxton, A., & Menger, F. Under pressure: An exhibition of printmaking by staff at the University of the West of England, Bristol. [Print]. Exhibited at Bristol. 26 March 2020 - 21 April 2020. (Unpublished)

According to The New Oxford Shorter English Dictionary print is ‘an impressed mark or image’. Print cannot exist without pressure. Letter press, the cradle of modern printing, even has the word press, pressure in it. Whether it is an ink jet dropl...

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)
