50 Unit exposure vs 25, ‘Bayer MaterialScience’

New photopolymer etching, 420 x 594 mm, named ‘Bayer MaterialScience’ (2016)

I named it ‘Bayer MaterialScience’ due to the text that becomes visualised through the process I use.

I’m using the usual process with static electricity, discharging it onto plastic and then visualising it with toner powder. An interesting development with this process has been the discovery of text. Usually I am just able to visualise the static charge, but I also have been able to visualise the text on the plastic wrapping. As the plastic wrapping is peeled away, I already hear static clicks – and a negative of the writing is left on the plastic. I then visualise the text. Interestingly, through the photopolymer process, the writing finds itself ‘corrected’ – it is no longer back to front in the final etching. This whole process in the etching workshop is a multi-layered deconstruction and play with the printing process.


Below, I also compare the photopolymer etching produced by using a 50 and a 25 unit exposure. I am not entirely sure which look I prefer. I think some of the detail has been burned out for the 50 unit exposure – some of the richness is lacking – but I like the particularly strong contrast for the 50 unit exposure and the way the text has become slightly accentuated.
