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), 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...

How to print a rainbow (2020)
Presentation / Conference
Klein, S., & Menger, F. (2020, January). How to print a rainbow. Presented at Dana Research Centre Seminar Series, London

In the 17th century Isaac Newton demonstrated that white light consists of the superposition of different wavelengths visible as colour on a screen. How colour was perceived by a human observer was explained by the work of Thomas Young and Hermann vo... Read More about How to print a rainbow.

The Canadians: a collective effort to fulfill a naive promise (2019)
Other
Klein, S., Menger, F., & Argyle, J. (2019). The Canadians: a collective effort to fulfill a naive promise

The project came about to fulfill a naively given promise. In May 2019 Susanne and her friend Marianne visited Canada to attend Marianne’s great niece’s wedding. They stayed with Marianne’s family. As a thank you for their hospitality Susanne, took p... Read More about The Canadians: a collective effort to fulfill a naive promise.

The optical properties of the Woodburytype - An alternative printing technique based on a gelatine/pigment matrix (2019)
Conference Proceeding
Klein, S., Leech, D., & Guy, W. (2019). The optical properties of the Woodburytype - An alternative printing technique based on a gelatine/pigment matrix. https://doi.org/10.2352/ISSN.2169-4451.2019.35.42

The Woodburytype is a 19th century photomechanical technique, producing high-quality continuous-tone prints that use a mixture of pigment and gelatine as a relief print, in which the variation in height of the print produces the tone and contrast. We... Read More about The optical properties of the Woodburytype - An alternative printing technique based on a gelatine/pigment matrix.

RTI for RGB: Photographing mica based inks on black paper using reflectance transform imaging (2019)
Presentation / Conference
Parraman, C., & Klein, S. (2019, April). RTI for RGB: Photographing mica based inks on black paper using reflectance transform imaging. Paper presented at Transactions: Imaging/Art/Science: Image Quality, Content & Aesthetics

Over the last century printers rely on the combination of halftones and subtractive CMYK ink primaries to translate an image on screen into a colour print on paper. This is certainly commercially expedient for many industrial applications. However, t...

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

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...

Collective dynamics in dispersions of anisometric pigment particles (2018)
Journal Article
May, K., Stannarius, R., Kang, K., Challa, P. K., Sprunt, S., Jakli, A., …Eremin, A. (2018). Collective dynamics in dispersions of anisometric pigment particles. Journal of Molecular Liquids, 267, 322-329. https://doi.org/10.1016/j.molliq.2018.01.172

© 2018 Elsevier B.V. Dynamics of suspensions of solid rodlike pigment particles in a non-polar solvent were studied in a concentration range from the isotropic up to the orientationally ordered nematic-like phase. Using dynamic light scattering and g... Read More about Collective dynamics in dispersions of anisometric pigment particles.

Optical and X-ray scattering studies of the electric field-induced orientational order in colloidal suspensions of pigment nanorods (2018)
Journal Article
Dozov, I., Buluy, O., Aryasova, N., Tereshchenko, O., Kurioz, Y., Nazarenko, V., …Reznikov, Y. (2018).

Liquid crystalline phases in suspensions of pigments in non-polar solvents (2017)
Book Chapter
Klein, S., Richardson, R. M., & Eremin, A. (2017). Liquid crystalline phases in suspensions of pigments in non-polar solvents. In J. P. Lagerwall, & G. Scalia (Eds.), Liquid crystals with nano- and microparticles, 845-869. World Scientific Publishing Company

We will discuss colloid suspensions of pigments and compare their electro-optic properties with those of traditional dyed low molecular weight liquid crystal systems. There are several potential advantages of colloidal suspensions over low molecular... Read More about Liquid crystalline phases in suspensions of pigments in non-polar solvents.
