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.
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.
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.
