RGB colour printing and halftoning for the reproduction of structural colour images (2023)
Presentation / Conference Contribution

Commercial CMYK halftone printing involves additive and subtractive colour mixing that requires the optical mixing of primary colour hues using different-sized dots to obtain variations in reflected colour.
Structural colour, as seen in nature, such... Read More about RGB colour printing and halftoning for the reproduction of structural colour images.

Maxwell's disappointment and Sutton's accident (2022)

One and many: Wet-Collodion and Woodburytype (2021)
Presentation / Conference Contribution

The invention of photography in the 19 th century changed our perception of reality for ever. Without the interpretation of an artist, an image could be recorded within minutes representing 'unfiltered' reality. Besides the scientific challenge how t...

Recreating the relief of the temple of the Jaguars: Exploring digital and analogue 2.5D printing of Mesoamerican imagery (2021)
Presentation / Conference Contribution

Digital and analogue printing methods are studied for reconstructing a Mayan decorative relief from the ancient temple of the Jaguars. Height maps, image files encoding height information as intensity values, were produced in commercial image editing...

Fast and furious: Photolithography (2021)
Presentation / Conference Contribution

A short history Photolithography, as we know it today in printmaking, has many origins. All were invented with speed of production in mind. It all started with a missed deadline. Alois Senefelder, a trained layer with more love for the theatre than f... Read More about Fast and furious: Photolithography.

Adventures in lithography (2021)
Presentation / Conference Contribution

Lithography is the most important industrial printing process for non-textile printing. Liquid crystal is ubiquitous in display technology. What happens when the two are combined? The adventure begins.
Lithography was invented in 1796 by Alois Sene... Read More about Adventures in lithography.

Colour deceives continually (2021)
Presentation / Conference Contribution

This paper explores the relationship between additive and subtractive mixing for printing colour. Using mica pigments that are based on additive colour mixing principles, that when combined, create white. Although currently used for decorative effect... Read More about Colour deceives continually.

Now you see it, and Now you don’t: Illusive colour (2020)
Presentation / Conference Contribution

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)
Presentation / Conference Contribution

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)
Presentation / Conference Contribution

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)
Presentation / Conference Contribution

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 Contribution

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 Contribution

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.

Syntax and desire in early landscape photography (2020)
