Drypoint: Using cardboard and perspex plates

 

Last week I showed you how I made the covers for the altered book I’m working on for “Books…Beyond Words”. This week I’d like to show you how the next stage is coming. I’ve been doing tests with drypoint using both card and Perspex (acrylic) for the plate.

For the book I need an image of a cocoon. I think I’ve mentioned (just a few times!) how much I want to learn etching, but the trouble is I have a few projects on-the-go, and a personal (exciting!) deadline of mid-May (more later!!!). I can foresee that a number of attempts might be needed before I can etch to my satisfaction!

Then this article from Nontoxic Print.com arrived in my inbox, showing me the way. I made the decision to try drypoint, also an intaglio print method, but a direct one, and therefore rather more straight forward than etching.

In the article Jenny Robinson discusses how she makes her large (e.g. 38” x 23”) drypoint monoprints using illustration board as her plate. She applies a thin coat of wood varnish and then treats the plate as she would any other drypoint.

With the high (and increasing) cost of copper and zinc, I thought this was definitely worth a try. As Robinson notes, cheaper materials provide the artist with more freedom to experiment, because you feel as if you can throw away something that hasn’t worked – and artistic freedom is always good, in my book!

Another cheap material that is often used for drypoint plates is plastic. I’ve heard of people trying virtually any type. Actually my kitchen chopping mat has some interesting lines appearing on it, and I’m thinking of swiping it and inking it up, but first I need to buy a replacement for the kitchen. More common choices are mylar and perspex, so I decided to give perspex a try too.

Tools, ink, paper 

tools

Apart from ink and paper, this photo shows everything I used. For paper I used two different Japanese papers in buff, one a medium kozo and the other with a little more texture.

I compared two inks, an oil-based etching ink from Graphic Chemical and a water-based one from Akua. The second ink was self-mixed using transparent intaglio base and the Akua Kolors, rather than the pre-mixed intaglio inks that are available. It really needed the addition of some thickener, which I didn’t have (but now do).

Tests & Results

1) Initially I began testing with tools that I had on hand – an etching needle (above – yellow handle) which I had used before for this my only previous drypoint (plate: perspex).

I knew I would want some tone as well as line in this print. I don’t own a roulette, the tool often used for achieving tone. In the article, Jenny Robinson talked about using carborundum, but the art store was out of stock. Initially, I decided to test some dry pumice (in the Matisse jar above) applied with acrylic gel.

drypoint 4

The result wasn’t bad, but the tone is more in the style of a collagraph, and that isn’t the look I am after.

2) Next I inked the plate with my self-mixed Akua. The ink was much softer and the textural effect of the pumice is lessened (pardon the shadow that’s come through on the scan).

drypoint 3

I wasn’t happy with the tone alone, and tried sketching in some detail in pencil.

3) I decided to add more line detail to the plate using an engraving attachment on the Dremel. I also tried wiping more lightly, so that more ink would remain on the plate.

I did quite like this result, but I felt the image now had a “man-made/machine” look to it. It’s an interesting effect, but I wasn’t sure it was what I wanted for the book.

collagraph

Here’s the plate (on the right) and the print again, this time using Akua ink. You can see I started experimenting with the Dremel’s mark-making abilities.

4) I wanted to test the Dremel further and decided to use line to achieve tone, a traditional drypoint/engraving technique. The plate here is perspex for the first time.

The result was a very controlled and neat image, almost illustrative.

5) At this stage I made another trip to the art store and decided to splash out on a “proper” drypoint tool (you can see it in the photo under Tools). I was pining for that special soft line that you can achieve when your tool lifts a burr from the plate. It is this that holds the ink and gives the drypoint its characteristic “look”.

And there it is over on the right side. All those lovely lines! I’ve finally worked it out!

tests on card (l) and perspex (r)

Still no carborundum at the art store, so I bought some Golden fine pumice gel, which you can see holds the ink quite beautifully. There are also tests with three different grades of sandpaper (150, 280 and 400 – reversed).

6) So finally I tried with my new scribe on a cardboard plate with the oil-based ink. I’m still working on my wiping technique, but this print is the best result so far.

Solar-powered techniques Part 2: Solarplate printmaking

Thank-you to everyone who has written to me with best wishes for my mother. After 8 days in hospital she is glad to be home. I was able to clear out most other commitments and made it as easy for myself as I could, so that I could be there for her as much as possible. I am pretty tired out now and am trying to take it easy in order to recover. I hope that you will understand if I don't respond to your kind messages personally.


In April I finally made it to a second workshop at Impress Printmakers Studio. My first one was in 2006 and was my introduction to artists books. This recent workshop was on Solarplate Printmaking.

Solar plates are a method of exposing plates either for relief or intaglio printmaking. It's another low toxicity technique that looks pretty simple and that I have been aching to try for about 3 years. Luckily, I purchased the "bible" on the technique around that time, as it is out of print and as time passes, the price is rising in a rather unbelievable fashion. Dan Welden took solar plates from their commercial application and experimented with their use in fine art settings. He wrote the book with an Australian scientist and artist, Pauling Muir and gave it the rather lyrical title "Printmaking in the Sun". I believe that a second edition is currently being written.

The book is amazing. It is wonderfully thorough but if anything, the talk of exposure times and test strips made me feel that I really needed to attend a workshop before I could give this technique a try. Once we went through it at the workshop, I realized that the basic technique is simple, although each print you make will be different and a certain amount of testing and "tweaking" is necessary to get the result you want.

The basic process is:
  • prepare your artwork on e.g. wet media acetate, OHT, drafting film (intaglio images are not reversed while relief ones are)
  • place your art and the plate in a contact frame and expose to UV light (the sun or a lamp/light box will harden the polymer in the areas it reaches)
  • remove and rinse in water, using a soft brush to remove areas that have not hardened (i.e parts of the image where the UV could not pass through to the plate)
  • print!

Personally, my greatest interest is in finding a way to make intaglio prints. I don't really like the idea of working with the acid and other materials necessary for traditional etchings. It seems very daunting. Recently Wim de Vos at Studio West End took me through the hard ground process, together with aquatinting and that has dispelled some of the mystery around the whole thing, but I still feel it could take me years to produce anything I find truly satisfying. I like the idea of working away here at home with solar plates; plus they provide the option of using my photographs as a starting point, which is very appealing to me.

The major drawback I can see with solar plates is cost. The plates themselves are not cheap: $14 for a 15 x 21cm plate against $7.90 for 12.5 x 20cm zinc plate. And while there are no other chemicals to buy for the process, it is quite possible to ruin a plate with the wrong exposure (once you've rinsed the plate, you can't re-expose if you aren't happy with the result). I guess this is where real discipline needs to be exercised to ensure you test your exposure and print your test plates, and keep testing until you have the result you are looking for. That way you are only wasting small pieces of plate, rather than a full plate. According to Dan Welden, it is possible to re-work plates by scratching into them with etching and drypoint tools, but I can imagine this wouldn't always give the result you were seeking.

Well, I suppose you might like to see some results from the day for yourselves. I'm not too sure how impressive they will look online, but they will give you some idea. I plan to re-print them using the old "pasta machine press" to see how the plates respond.

This first test (below) is an intaglio print made with some of my cloud imagery. This was originally part of this photo.

This silhouette (below) comes from the cover of "Resistance" (which by the way I hope to return to soon, now that the weather is cooler). They were both printed in both relief and intaglio. The lovely thing about them is the debossing, which you can't really pick up in these pictures.

Flag Book - maquette

maquette of flag book by Amanda Watson-Will
This is a rough maquette of a flag book I plan to make as part of my masters. The white concertina spine will be blue sky in the finished book, and there will be imagery on the front and back outside covers as well. The next stage is to write the text, which will be on the back of the flags.


The concept for this book is based on the idea from Buddhist meditation that thoughts, feelings, sensations are constantly changing, drifting across the mind like clouds in a sky. To cling on to our states of mind is as futile as expecting the weather to be constant.

From what I have read, it is typical to make a mock-up or maquette of an artists book to help ensure that things like size and materials are consistent with the artists meaning. After constructing the middle section I realized that it would add to the meaning if the flags were attached to "sky". I also discovered my flags are too far apart for my liking.


I would really love to make this book in a large size (A3 or A2) to fit with the idea of an expanse of sky. That would mean having it professionally printed and to achieve the quality I want, I might have to apply for a grant to fund printing. I spoke to a printer yesterday about offset printing and they said they did not know anyone who would do such a small run - so that means I would have to send it interstate. Hhmm!

Inkjet and mixed media tests: Part 2

I have been reading the wonderful "Digital Art Studio" by Schminke et al. As the subtitle indicates, it explores techniques for combining inkjet printing with traditional art materials. I am searching for ways to incorporate my photos into my artwork and this book is a terrific source of technical know-how in this area. With the improvement in the archival qualities of inkjet print now available, there is no reason not to incorporate them into fine art projects.
A product they use in many of their works is InkAid. This is a brush-on medium which allows you to print on any surface which will pass through your printer without the loss of colour intensity or durability that is seen e.g. when inkjet prints are made on fine art papers. Sometimes the softer effect you can get by printing on say watercolour paper may be desirable, but at other times it is not. InkAid is the answer to this. BTW I have no affiliation with InkAid(!) I just think its a handy product.
It also allows you to print over collage or mixed media surfaces. This is the process that I have experimented with. I first printed a very low opacity version of my image onto watercolour paper to use as a positional guide. Then I added gesso and artists pencils to achieve a handworked texture. I then applied two thin coats of semi-gloss clear InkAid (my 1 litre bottle is going to go a long way!). When dry I ran the watercolour paper through my printer again, applying the image at 100% opacity this time. Here's the result - hopefully you can pick up some of the textural effects.



Next I thought I'd try a transfer as my initial layer rather than a low opacity print. I thought this would add more character and texture. Using Petitts method, I made my transfer of the sea over a print of the times. I love the rough effect at the edges but a lot of detail has been lost, as you can see (apart from the poor photo - sorry!)

Next I added gesso and artists pencils (below)


Finally I applied the InkAid and running through the printer to add the final layer. Unfortunately I wasn't happy with the result at all! As you can hopefully see from this detail shot (below), I lost the lovely rough edges (of course!) and the effect of the InkAid over the acrylic gel medium that I used for the transfer is quite plastic-y. It really doesn't work with the textural effects I was trying to achieve with the gesso. So... that isn't a process I will be bothering with again. Nevermind, you have to try these things to know.
