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...

Retrieving the ancient colours: Artistic practice as a tool for heritage reconstruction (2020)
Conference Proceeding
Trujillo Vazquez, A., Klein, S., Calvet, X. A., & Parraman, C. (in press). Retrieving the ancient colours: Artistic practice as a tool for heritage reconstruction

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.

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...

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.
