What Is Mezzotint ?

What is mezzotint ?


Mezzotint is a printmaking technique where the surface of a copper plate is worked with special tools in order to produce an image. The technique is part of a family of techniques called intaglio, where once the plate (matrix) is ready for printing and ink is applied, the ink will sit in grooves and pits lower than the surface of the plate.


A mezzotint is an original print: this means that the print is not a reproduction of another existing artwork, like a digital print would be a photocopy of a drawing or painting for example, but is an original in itself. Original prints may be part of an edition; in the case of a mezzotint the edition generally is made of only a few dozens as the copperplate degrades after a certain number of impressions. Some mezzotints have larger edition because the artist has had the plate steelfaced ( plated with a thin layer of steel) which makes it harder hence more durable.

The characteristic of mezzotint is that it is a tonal technique ( no lines !): the image is created by producing black, gray and white areas, and it is possible to obtain some very smooth transitions between these different shades. Mezzotint, also called maniera nera in Italian, manière noire in French and manera negra in Spanish, is well known for producing the richest and darkest black of all the intaglio techniques. 


Mezzotint is a very laborious process as it needs a long preparation before the artist can even start working on the image. The plate needs to be roughened up with a special tool, called a rocker, that indents the surface with thousands and thousands of small pits that will later function as receptacles for ink. This preparation takes many hours, depending on the size of the plate. 
Once the surface is ready, in order to produce an image the artist has to scrape with a blade or smooth the metal with a burnisher so that the pits become more shallow (and will produce grays once printed) or disappear altogether ( for whites). This too is a lengthy process. 


Once the artist is happy with the image on the plate, it is time for printing it on paper. The plate is covered in creamy ink, which is then carefully wiped with a gauzy cloth and with the palm of the hand  so that the excess is removed and the ink is only left in the pits. The plate is then placed flat on the bed of a printing press with a sheet of damp paper on top and as they pass under the roll the ink is transferred from the plate to the paper: the image finally appears in black and white. ​

Hortus : an Artist Book

24/2/2020

I am very excited to finally share with you a project that I have been working on these past weeks.
You might already know how, as a EU citizen, I found the UK political situation of the past three years quite upsetting. As the uncertainty was coming to an unescapable end I set out to make my first artist book as a personal response to events.
The book features five of my mezzotint engravings and it's made completely by hand in an edition of 4.
Here below is a short video filmed by Alberto Lais.

Hortus was conceived as a small Herbarium of Mediterranean plants that I collected on my street. They make the street more beautiful and diverse, and particularly the large olive trees have surprised me for how well they adapted to this colder ( less so now perhaps) climate.
The parallel with my own life was obvious and it sparked a series of mezzotint engravings that I titled Immigrant Plants. The idea of collecting these in an artist book came when I learned of a herbarium put together by my ancestor, the pharmacist and botanist Stefano Rosselli, in 1575. I wrote about this extraordinary object here.

I am pretty stubborn and I wanted to make the book on my own, so I set up some sessions with book artist Mark Cockram. He showed me how to bind the pages, set movable types for the letterpress text, and how to make a box, then sent me home to work. 
The books, an edition of 4 completed on the 31st of January,  turned out exactly how I envisioned them !

How to Make a Mezzotint Print

15/12/2019

Recently my Instagram contacts seemed quite interested in how mezzotints are made, so here's a more wordy breakdown of the process. 
Because of the time scale involved in the work, most mezzotints are relatively small. Mezzotint plates can be bought ready made, but I find that the process of preparing a plate very rewarding and ritualistic, and that it ultimately somehow adds to the poignancy of the image.
Picture


At the start the copper plate's surface is completely smooth. Preparing it for a mezzotint means roughening it up so that it will feel like very coarse sandpaper. 

Picture
The tool used for this work is a rocker: a metal blade that looks a bit like a herb chopper, but with tiny teeth, like a comb.
Rockers exist in different sizes and also with different teeth "density": the most commonly used have a "teeth count" from 65 up to 100. I have a 45 and an 85. The lower the count, the more it takes to prepare the plate but also the more shades of gray one can achieve.
The rocker needs to be sharpened regularly while preparing a plate, another skill I had to learn for this technique.
My rockers are mounted on a jig and a pole rocker to help me achieve a regular movement and protect my joints from excessive strain during the lengthy preparation. It is still a repetitive movement that ends up hurting my joints so I can't do more than a couple of hours at the time.

Picture
Here below is the actual rocking of the plate:
The blade is gently rocked sideways and it slowly "advances" on the plate, leaving behind a series of microdotted lines. The plate is then rotated by a few degrees and the process repeated so that after the many passes (I do 40 to 50 passes) required to complete the preparation the surface is completely rough and lines are no longer visible.
The plate is now ready. Should it be inked and printed at this point it would result in a black rectangle. It is time to start scraping the lights out.
I draw the image on the plate in pencil and start working on making the surface smoother in the areas that will be lighter. 
The lights are buildt slowly and the darks are carefully preserved. The scraping movements are short and sharp in details while longer strokes are used for larger areas. Scraping has to produce some thin dust as it effectively removes a thin layer of metal at each stroke.
While I work I use a softbox light to avoid strong refraction on the plate.
Here below is an image of the print obtained from this plate, regrettably the photo does not convey how velvety the print looks on paper !
