Blue Printing Weekend Fun
Beautiful Blue Print Posters hanging to dry…these were made by our workshop participants
Last weekend a collection of brave souls joined Carla (from Trade Roots) and myself in a Blue Printing Workshop. Everyone made a killer blue printed poster and learned the method so they could make their own at home. I promised to share the details and the steps here on the blog…so here it is.
You will need:
- Photographers Formulary Cyanotype Kit 07-0090 or the pre-mixed liquids. (I bought it on amazon.com)
- Water Colour Paper (the paper will be submerged in a water bath)
- Paint brush or foam brush
- Freezer paper to line your work surface and a board to work on
- Gloves, Apron and no fancy shoes
- Sink or basins to rinse your picture
- Sunny Day (or at least a break in a rainy day:)
Steps to make an 8×10 poster:
- Select an image you want to re-create in blue print. Size the image to 8×10 (the size of transparency sheets) and then change the image to black and white ….once it is B/W then invert the image so the black and white parts are reversed. I used paint.net but there are lots of free programs online that will help you do this. print the inverted image onto a transparency sheet.
- Secure water colour paper to the frezer paper lined surface. (You will be taking your project outside so be sure it is a portable board or tray – we used cardboard lined with freezer paper)
- Mix your cyanotype solution in a dark room per the directions and brush it onto the water colour paper in a cross hatch pattern. Cover it well, but don’t use too much liquid – no pooling. It should appear moist and yellow with no REALLY wet spots. Once covered let it dry. Once dry repeat this step. This is done in a dark room.
- Once your paper is dry place your transparency on top and secure it. You can use tape or place a piece of clean plexi glass or glass on top.
- Take your project outside into the sun and place it quickly and keep it still. More direct sun the better, but on a cloudy day it will work…just stay outside a little longer. On a moderately sunny day it takes about 5 minutes. The paper will turn dark green or blue as it exposes.
- Remove the glass and the transparency and submerge your project into a bath of water, you can give it a good wash until it runs mostly clear. The last dunk should be in a bath of water and peroxide. This appears to deepen the blue.
- Hang to dry.
This poster by participant Ryan turned out particularly well. great job everybody!
