Custom kites can be really interesting to be used as a marketing tool and not so expensive as you can imagine.
Using your kites as advertising can be good for those running their own bussiness as it is a way to continue "working" while you are on the water.
In some cases you may be able to claim/reduce the cost of the kite or printing as a tax expense (advertising), as well as you are advertising your business. Check with your accountant first.
Also you can "sponsor" yourself working for a friend/family/local bussiness making their promo while you are kiting. You don't really need to be a PRO-rider to be sponsored if you can find someone interested on promoting his bussiness using a kite.
Check Griffin Kites custom kites website:
http://www.griffinkites.com.au/custom-kite-prints
You can download a template on the website. You can choose your favorite color combinations and/or print your logo on the kite.
To get started, simply email a logo and 3d renders can be provided to see what the finished product will look like.
Screen art is to be provided in illustrator .EPS or .AI format.
Limitations: Avoid printing near the leading edge (top of the kite ) as this area of the kite is very curved and we can not print a flat screen onto it. Screen max size is 2.4 meters, avoid having a screen print larger than this. Custom kite can be quoted when your Illustrator file is received. Solid colors only. Download a flat template here
Once screen prints are made, it is no extra cost to have more kites made using the same screen. You can use the same size logo on different sized kites, or you can make a different size screen per kite size.
