If you want to know how to print on shadenet, here's how easy it is.  Using shadenet ink which is a water-based ink specifically designed for printing on shadenet, you can use your normal screenprinting or spraypainting methods.   There are some simple instructions available at this web address http://www.shadenetink.com/product.htm on how to print on shadenet.

The clear base shadenet ink is easy to apply.  The only important thing is that it must be dry enough between coats.  You can decide how many coats you want to do, depending on what kind of finish you want.  Less coats leaves the holes of the knitted HDPE shadenet open so that the wind goes through it and it retains all of its stretchy qualities.  It also saves you money.

For a better finish, apply a few coats of shadenet ink to cover the holes and give you a flat surface and then your colour coat.  This will give you a nice high quality finish.  By applying two coats of the clear base ink it means that the ink doesn't show through the back so you can't see the image on the reverse side of the shadenet. 

You can use your own outdoor pigments and thickener with shadenet ink when working out how to print on shadenet.  Mix them as you would for any other water based inks.  Ideally you want long table about 1.5m wide.  You can roll up the shadenet in between the prints and it can hang over the sides if it's too wide.  There are some more comprehensive technical instructions if you are keen to learn how to print on shadenet.
