Painting Retractable Screens
Yes it is possible to paint a retractable screen!
You have to be able to leave the screen down for at least a week for the paint to fully dry. Ideally you would leave it down long enough for the paint to fully cure.
From my own experiences I do not recommend anything other than a matte exterior paint that is self-priming. Exterior paints are more flexible to withstand temperature changes. They are also very durable and UV resistant. The self-priming allows you to reduce the coats by one. The thinner the paint the better.
I only recommend a matte washable paint because a matte finish will not show the screen waves or imperfections in the image.
IMHO, Behr Premium Plus Ultra™ Exterior Flat #4850
is the best choice for painting a retractable screen. You can paint it white or choose one of the tints presented in the DIY Custom Gray Tints For Behr Ultra Pure White Paint

The first thing you need to do is devise a way to hold the screen with some tension on it.Click image to enlarge.
Here you can see I used weights, bungee cords, and spring clamps to hold the screen in place while I painted it.
Mask off the black border with painter's tape. Having adequate light can make a difference in how well you smooth out the paint.Click image to enlarge.
Then simply paint the screen as you would if you were painting the wall.
You can save paint by bagging the roller between coats.
I recommend two coats to ensure good coverage.
Here are the results that I have enjoyed.
