Today I printed from my perspex etchings and achieved some nice results!
To do this yourself you will need access to a laser cutter and a printing press.
To achieve the depth of etch on my perspex,
Here are the settings I used:
- First convert your images to black and white and up the contrast on photoshop.
- On the laser cutter, set your images to the size you want (mine are 13.5 x 15.5 cm).
- Posturize your images.
- Use the rectangle tool to draw around your images.
- Change this rectangle to hairline and colour red (this indicates the laser to cut all the way through the perspex)
- Go to printing preferences
- Advanced – set the etch cut to 3mm
- General – resolution – 300 DPI
- General – engrave direction – bottom up
- General – image dithering – Floyd Steinberg
- Colour mapping – black – speed 60, power 100
Feel free to play around with these settings further to achieve different results.
Today I have been etching my collection of photographed textural matter onto perspex with the laser cutter.
At a later stage I would like to experiment with printing from these perspex etchings.
To see the results of my perspex printing experiments, please see Perspex etchings and prints.
Here are some of the photographs of textural matter I have been capturing and collecting since the start of the semester.
I have been incorporating my photographs into a range of different materials and processes, including cyanotype, screen printing and perspex etchings.
I will be using a number of my collected images in my degree show pieces, along with a variety of opposing disciplines.
Today I am experimenting with latex.
I have used my collagraph plaques to create these latex reliefs.
What you will need:
What to do:
- First you will need to apply a layer of vaseline to protect your textural surface and ensure that the latex can be easily removed once set.
- Follow the instructions on the latex bottle & latex hardener and mix accordingly (usually 1 : 10).
- Give the mixture a stir until you feel the latex stiffening.
- Apply the latex to your surface in thin layers.
- Wait for each layer to dry before applying the next.
- Build to the desired thickness (I used about 4 layers).
- When all the latex is set you can peel it way from your surface.
