The dark blue paper is treated with a chemical that makes it light sensitive and reacts when placed out in the sun. The proper name for this is Cyanotype. Objects are placed on the paper and leave behind a negative image once the treated paper has been exposed to the sun.
I love the look of leaves and flowers, but I wanted to use some items from my craft room. So, initially I made some prints using buttons, lace and a Tim Holz mask backing.
They turned out nicely, but weren't quite what I was looking for. I liked the detail on the lace and wondered if I could somehow make sun prints from detailed rubber stamp images. After some trial and error, here's how I did it.
[Note: The directions below are specific to this kit, but each manufacturer's kit will be slightly different, so be sure to read and follow the directions on the one you purchase.]
- Keep unused sheets of sun paper in the protective bag until you need to use them. They will begin the change color with any exposure to light.
- When laying objects on paper and putting them out in the sun, ensure the sheets remain dry. The tiniest drop of water will mark the paper. This is especially important if using botanicals of any kind.
- Place sheets in water the minute the paper turns white otherwise the image will be come overexposed.
This card, made with an Oxford Impressions stamp, has a plain sun printed image as its focal image.
This final card has a sun print as it's background - the image is from Artistic Outpost.
This was a fun project to do outside on a sunny day - I hope you'll give it a try!
