Trying to export images but get "noise" where it should be transparent?

[andyp]

Hi there!

I've just started using ArtRage Lite, which I got as a free download with my purchase of a Wacom Intuos Creative Pen Tablet. Its on my Windows 10 laptop.

I've managed to create some simple images so far which i did with the "cell" special paper type as I only wanted a simple graphic on a transparent background. It looks just as I want within the ArtRage software (with the white/grey checked background) however when I try to export to a JPG, GIF etc. the resulting images all seem to have noise in the background - like bands of speckled shading - which weren't there in ArtRage.

I've tried filling the empty spaces with white but it still does the same?

I'm literally just trying to create a simple black image. Here is an example:

Please can anyone suggest what the problem is and how I get a nice, crisp black image with transparent background exported?

Thanks
