Some bagpipe music by Gunnar
Print out your photo or illustration from the computer on OH-paper in grey scale and best quality!
Take a Polymer sheet and put your OH-paper on top. Then illuminate for 12 min (the time is changing depending on what kind of lightsourse you are using, but it has to be UV-light)
Illuminate another 12 min with a grained sheet (screen paper?...around 80)
Put in water (20-25C) for 1 minute!
Wipe the polymer with a soft sponge for another minute
Rince it off!
Wipe it of and then either put it in a drying cabinet or use your blow dryer until it is really dry
Cut out your picture
Polish the edges
Illuminate again for another 12 minutes
Now its time to prepare the colour
You have to work the paint until it gets really smooth and nice
If its too thick add some vaseline and some rapeseed oil
Now its time for the printing!!
