Nine small collagraphs to experiment with texture by Liz Arnold, September 2015

The Collagraphs

Amongst other things, I made 9 small collagraphs (printing plates) (4.5 x 3 inches) over a period of a few weeks (quite a bit of drying time for various layers). They were experiments to create texture and to see how much depth variation gives a good print when using the press. The answer is “not much”. The plate at top right has circles punched from an old dilapidated paperback and crocheted cotton thread. The circles printed well but the crocheted cotton thread was probably a smidgen too thick as it trapped a lot of ink. I used (hogged?) the press at PAWA during the last Saturday Skill Sharing Session and the other members were really helpful in showing me how to set the press up, and how I should leave it when I’ve finished printing.

The Prints from the Collagraphs

The second photo shows the prints from those 9 plates. The very first print I did was the one with a big splodge! 🙁 I had too much pressure on the press – and possibly too much ink on the plate as well. The pressure was reduced for the remainder of the prints and I like how those came out.

Top row: 1/ cotton yarn, thin card and sand, 2/ watercolour paper strips, 3/ book page circles, the top of a bread mix bag, thin card strips. Second row: 1/ thin card and carborundum, 2/ eggshell (I put all sharp edges pointing down ie outside surface of egg up, and after I glued this the first time I rolled over it with a rolling pin and then applied another 2 layers of glue so there were no sharp bits sticking up), 3/ scrunched tissue paper. Third row: 1/ the top of a bread mix bag and thin card strips, 2/ crochet cotton, paperback page punches, 210gsm card rings, and thinner card strips, 3/ watercolour paper strips.

When I did these prints the plates had all had 8 coats of spray varnish. When I cleaned them they went a bit soft so I put them in the sun to dry for a couple of days to make sure I wasn’t trapping moisture inside and have since given them another 8 coats. Spray varnish doesn’t obscure detail but I don’t like the smell/effects on me even though I’ve been using a mask and spraying outside (staying downwind). I’m going to try brush on varnish which I was avoiding as I thought brush marks might give an unwanted texture. It’s probably just a question of getting the “knack”.

Art Supplies from the Hardware Store

I bought these cords from Bunnings today to experiment with. The brightly coloured Polypropylene string (1mm x 60m) was $4 for the 5 reels, the white Venetian Blind cord (2mm x 30m) was $4 and the Grunt cotton sash cord (5mm x 5m) was $4.  The Dunn braided cotton rope (15m) was $3.50 in Big W.

I’m planning to experiment with netting, knotting and weaving (maybe even *gasp* macramé) and possibly using them to create more collograph plates. Although with my present luck making/using collograph plates I should probably steer clear of those for a week or so 🙂

The blind cord says it is “abrasion resistant” and although it doesn’t say what is made from the end feels like it has been heated to prevent it from unravelling. I will have fun with all of these I am sure.

Collagraph Plate experiment – loom bands

How I made the collagraph plate

To make the collagraph plate I sealed a piece of thick card with Atelier Regular Gloss Gel and used the gel to adhere some loom bands. A big tub of loom bands were bought for $1 in a reject shop (obviously not the “in thing” to do anymore). The bands were adhered to the card with the idea of using it to remove paint from the Gelli® plate and also as a collagraph plate in it’s own right.

Collagraph plate problems

Collagraph plate made from loom bands glued to thick card using Gel Medium. When I used Matisse Block Printing Ink the stickiness of the ink was strong enough to pull the bands off of the board. But there is an interesting texture left in the medium ?

The top half of the photo shows the state of the plate after only a few prints. The lower half shows (l to r) a previously printed sheet overprinted from the cardboard plate, a ghost print from the Gelli® plate, a print from the cardboard plate, a print from the Gelli® plate.

I had applied 3 coats of gel to adhere the bands. This time I decided to experiment with the Matisse Block Printing inks after the disaster with the Shellac/acrylic paint/open medium disaster. The block printing inks are much stickier than the paint mixture. So sticky in fact that they started to pull the loom bands off the gel medium! So this too has turned into a mini-disaster. It’s just not my week 🙁 I will try other glues to stick the loom bands down as I really like the effect of these slightly “off” circles. The block printing inks didn’t really cover very well on the Gelli® plate either so I got lines/patchiness and sometimes the roller picked the ink up again as I rolled. So I probably need to use some other base for mono-printing with the printing inks. The bands that have come off have left an imprint in the gel medium so maybe all is not lost – maybe I can take all the bands off and use the texture of the gel medium as a printing plate. I managed a few prints before the loom bands all started looking a bit loose.

Collagraph Plate experiments – shellac disaster

I used the woven card collagraph plate sealed with shellac to print using Jo Sonja and Atelier artists acrylics mixed with Derivan Matisse Open Medium to extend the drying time of the paints.

Problems with cleaning the collagraph plate

It was ok until I came to clean the plate – at which point it became a disaster. I managed 5 prints. I did notice that the plate had become sticky after the second print but I thought that was the paint. Then I noticed that the smell had changed – not for the better. After 5 prints I decided to clean the plate. I submerged it in water and wiped with a cloth. The paint didn’t move so I scrubbed with a nailbrush. The paint and shellac all came off where the paint was in contact with the shellac – so the card absorbed quite a bit of water.

The shellac coating came off when washing (submerged in cool water and scrubbed). The shellac came off where there was paint. I think the Matisse open medium acted as a solvent for the shellac. It didn't come off where there was no paint.

Where there was shellac only (around the edges and on the back) the shellac remained intact (even when it was scrubbed with the nailbrush). I can only conclude that something in the open medium affected the shellac (or maybe the medium in combination with paints from another brand). I must admit I was not using the Matisse open medium with the Matisse Structure paints for which it was intended so it could be the combination and not the open medium by itself that has caused the problem. I have left the plate in the sun to dry out as I quite like it as it is so it could be sealed once dry and re-used for another purpose.

Lessons Learned

I learnt that I should have tested the shellac as a waterproofing agent on some small pieces of the card rather than using it for the first time on a plate that took me several hours to make. Then I should have tested the painting medium on those samples. My reading had indicated that shellac was the way to go but most of the books I was referring to were pretty old – open medium and paints that can be “unlocked” have been developed since they were written. The information I had would have been written for plates that were intended to be used with printing ink (which at that time would have all been oil based I imagine). Now I do actually have some Derivan Matisse Structure paints and some of their Block Printing inks (water clean up is also a recent development) so I guess there is a whole new area of enquiry right there. The question is – am I ever going to actually produce any artwork or am I going to carry on testing for ever? 🙂

Collagraph plate experiments – thin card + shellac

How I made the collagraph plate

I have finished weaving paper (it took me ages – much longer than I anticipated!) to make another collagraph plate.

I used Selly’s Exterior Aquadhere PVA to glue the finished weaving to a piece of thicker card previously sealed with WestArt Crystal Clear spray varnish (but I forgot about that when I glued the paper weaving on).

Once the glue was dry I sealed both sides with Shellac. I think I did about 6 coats on the weaving because that is going to get a lot of use, and I did 2 on the back because I realised that it wasn’t soaking in as I had previously sealed the thick card with WestArt Crystal Clear varnish. So that indicates to me that the Crystal Clear may be a good enough water-proofing agent by itself.

I really like the appearance (and the feel) of the paper sealed with Shellac and will experiment more with this on different papers/fabrics/threads. I’m also wondering what Shellac would look like over different colours of paper/painted paper. Tissue paper and brown paper could look very interesting.

And I still like the broken lines that look like code too 🙂

Collagraph plate experiments – thin card

Artwork by Liz, Artwork Experiments, Uncategorized

I have been experimenting with making printing plates from various materials I had on hand (some of which I had bought years ago but never got around to trying of course). These can be used to remove paint to create texture on the Gelli plate (if they have some flexibility and no sharp projections) or as printing plates in their own right. I recently did quite a bit of reading about different ways to create collagraph plates. In particular I was interested in ways of waterproofing the plates if they were made from materials which weren’t already waterproof such as paper/card or fabric. This is because I have had experience in the past where some glues become sticky again when wet.

"<yoastmark

I have made one out of thin card (140gsm) and paper shapes glued onto a thicker card (600gsm) which I have sealed with 2 coats of Atelier Regular Gel (Gloss) and 2 coats of WestArt Crystal Clear spray varnish. Concerns are that the edges will not be waterproof as it is difficult to make sure they are coated. I haven’t tried it yet and as they say “the proof of the pudding is in the eating”. I have since read that Shellac waterproofs paper and card because it works by soaking in rather than sitting on the surface. This has 2 benefits: the entire plate is waterproofed rather than just the surface, and fine details are not filled in by the sealant.

I am therefore in the process of making another plate, with the texture of weaving, from the same thin card which I will glue onto thicker card and then seal with Shellac (which I have used before to seal wooden stamp blocks, but not for paper). I am interested to know whether the texture of the weaving will show or whether I will just get dots in a regular grid from the high spots.

These are the marks that were on the scrap paper that I cut into strips to make the woven paper collagraph.

While I was making this I became intrigued with the way the lines that were printed on the thin card were displayed in a completely new way. It looks almost like a code or cipher. So I’ve filed this away in the back of my mind in the “inspiration” category.
