Happy Valentine’s Day Eve!






Do you remember Valentine's Day when you were a child? Buying a box of cards for your whole class, exchanging them, and coming home with a bunch of heart-shaped greetings? That's the feeling I wanted to convey when I thought about creating a design that I could copy and send out to family and friends. How best to do it? Carve a stamp? Create a painting and then scan and copy it onto cards? No, how about a collagraph! I had good results the first time I tried it which yielded a Celtic Horse.

Looking up collagraph in "An Introduction to Art Techniques (DK Art School)", I read that a collagraph is like a texture stamp, where you build up materials on a base such as sturdy cardboard and then ink up and print. I didn't have a design in mind but started sketching on a piece of thick cardboard that would fit some Strathmore Creative Cards. With a pencil, I marked four corners where the collagraph plate would center on the card but, as it turned out, I didn’t need to do this because I did not use it like a stamp.

Cardboard plate

Once happy with a series of hearts, I traced the design using a squeeze bottle with a fine-tipped stainless steel tip filled with gloss medium. I let it dry overnight.

The next day, I began printing the cards. The only red ink I had on hand was a dried up ink pad, so I experimented dabbing on fluid acrylics with a cosmetic sponge. After using the plate like a stamp, I saw it did not capture any design details so I left the plate right side up and pressed the card into the plate. Using my fingers, a hand baren, and a plastic card, I traced the raised lines into the paper.

The fluid acrylics did not work well because they dried too fast. Adding a little water only smeared the design. Using too much pressure with the baren and plastic card made the card paper stick to the sticky plate when I pulled the card off. After seven prints I tore the cardboard plate. Yikes! This might have happened because I was trying to clean it off after each print and too much water probably weakened the cardboard. Also, I had not sealed the entire cardboard either. But, since I’d used a cheap material—cardboard—I also wasn’t surprised when it did not perform.

Pastelbord plate

So, I rummaged around and found an Ampersand Pastelbord and did the same type of design again, this time reversing the placement of the big and little hearts. Yes, I’d forgotten when designing the plate that the printed image would be reversed. Another day went by waiting for the plate to dry and I decided to try materials better suited. At craft stores I bought a tube of block printing ink as well as a pigment ink pad. As Scotty on Star Trek would say, “the right tool for the right job”!

The new plate and the new supplies were successful. Trying both the ink pad (rubbing the pad over the raised plate) and then the tube ink (squeezing out and dabbing with a sponge), the details came through much better.
Next time, here are other things I plan to try:

Use string instead of gloss medium
Use gesso instead of gloss medium
Use bits textured fabric
Use a larger nozzle, if using gloss medium
Use different card material, such as heavier weight watercolor paper
Use smoother card material instead of the very pebbly paper surface

Ah, well. I wanted that hand-made, imperfect look. And the feeling of getting a special Valentine.

And, I think I got both!

Experimenting with Collagraphs

Have you ever tried making a collagraph? It is a type of printmaking where you build up the surface, rather than subtracting (as in making a stamp). You can use any kind of firm material for the base (cardboard, mat board scraps, canvas board, etc.) with various glued down flat objects (leaves, fabric, coins, etc.). With such a range of ingredients, it can be very creative.

Long wanting to make a collagraph, I could not settle down and decide on a premeditated design so I looked on my shelves, thinking about what size to use and found an unfinished painting on Gessobord. It had been an experiment—the first time I had tried using an acrylic medium called string gel. Dipping a palette knife in the jar, I then lifted it and swirled it over a section of the rigid surface.

Now, I was curious—would it make a good collagraph? Since it already had a raised design on the surface, I wouldn’t have to wait for everything to dry overnight (or longer). Bonus--I could play now!

Trying various papers and full-body acrylic paints on hand, I first tried rolling paint on a brayer and transferring it to the raised design. It didn’t work very well, so I switched, using a brush to put paint on the hardened string gel. This yielded much better results.

Limiting myself to just three colors (blue, teal, brown), I began to see a horse’s eye, a muzzle, and then an abstract body. The swirls reminded me of Celtic knots and spirals. Cool!

I tried other variations, using Cotman 140 lb. w/c paper, inkjet translucent vellum, and beige cardstock. Surprisingly, the plain computer paper showed the most details.
