On aquatint using hair spray

by Debora Ando

 

I would like to introduce this method as an easier and more practical alternative to aquatint materials already in use in print studios and schools. Hair spray is a chemical product and therefore may cause allergies or reactions. For precaution wear adequate gear and designate an enclosed space where the hair spray can be handled avoiding spreading of the particles.

Hockney Printmaker at the Dulwich Picture Gallery

I saw a superb exhibition today; David Hockney’s prints at the Dulwich Picture Gallery. I am a big admirer of all of Hockney’s work; I admire his strong original drawing skills, sense of balance and rhythm, and use of colour; most of all I love the way he tells stories with image. I have longed to see his print work exhibited and this show did not disappoint, I came away marveling at Hockney’s range of image making in print, from the spare, pared down line work in etching through to the exuberant large scale colour lithographs.

Photography into Etching – Hand Colouring

I have finished a 3 day course on photo etching at City Lit taken over 3 weekends.

You can read about it here.

A couple of the prints with chine-collé weren’t working well, so I added some hand inking to see if I could get a more harmonious image. Have a look at the before and after photographs below.

Photography into Etching Day 3

I have finished a 3 day course on photo etching at City Lit taken over 3 weekends.

It was a fantastic course; a great group to work within and an excellent teacher Anne-Marie Foster.

On Day 1 we were introduced to the principles of photo etching; the three different techniques to get source material onto transparent acetate in readiness to expose to a prepared photopolymer plate. We produced a test plate and printed it to understand the process and how to get tones to print successfully. You can read about Day 1 here.

On Day 2 I prepared one of my own artworks in Photoshop for tonal photo etching; and printed test plates. You can read about Day 2 here.

On Day 3 I wanted to try different ink colours, different paper, chine-collé, and maybe colour rolls. I didn’t have enough time to get to try all I wanted. Below are the various experiments and results. I intend to work further on some of the prints with inks; so more to come on that.

Photography into Etching Day 2

I am attending a 3 day course on photo etching at City Lit over 3 weekends.

On Day 1 we were introduced to the principles of photo etching; the three different techniques to get source material onto transparent acetate in readiness to expose to a prepared photopolymer plate. We produced a test plate and printed it to understand the process and how to get tones to print successfully. You can read about Day 1 here.

To photo-etch and print a tonal image successfully from my source photographs or original artwork, I have to introduce digitally texture, like ‘dots’ to the image (like a newspaper image is made up of dots), so that the image photo-exposes and acid etches these ‘dots’ as ‘pits’ to hold ink and so print a tonal image.

Photo into Etching Day 2: Source Image

First of all I wanted to find a really good tonal image so that I could fully get to grips with the Photoshop techniques required for adding texture to the different areas of tone. I found a tonal colour image that worked well in grayscale, but I felt it was a little boring, so I combined it with a line drawing I made of the same subject. Combined in Photoshop using ‘clone stamp’ tool, and ‘multiply’ option on new layers.

Adding Texture to Tones in Source Image

The next step was to separate onto different layers the dark tones, midtones, light tones and white areas of my source image. Using the ‘magic wand’ tool I could make these specific selections of tonal values and copy to a new layer. To add texture to the tonal areas we would simply be applying the filter ‘noise’ to each tonal layer; the darker tones would require a higher value of ‘noise’ than the lighter tones. As I wanted areas to remain as white paper, I did not apply the ‘noise’ filter to my ‘white areas’ layer. See below for a close up of a section of my image for before and after ‘noise’ filter is added. It is a bit difficult to see the ‘texture’ below; in Photoshop when you view ‘actual pixels’ you can really see a difference.

Once I was happy with my filter application I printed out the source image onto acetate and printed a test plate to see how the tones would print.

It is hard to see in the images below but after my first print I felt I could add more ‘noise’ to the darker tones in my image and lessen the amount of ‘noise’ on the midtones i.e to make dark areas darker and midtones area lighter.

I adjusted my image; printed onto acetate and printed a second test plate; which I think printed better than the first – though admittedly hard to see the difference on here.

Anyway I managed to prepare a final printing plate from the 2nd acetate I prepared, so Day 3 will be spent in final proofing of the image; trying different ink colours, trying different paper, trying areas of chine-collé, and maybe trying colour rolls.
