How to create a White Base on Illustrator CSI have always
I have always created easy designs on Illustrator, and ALWAYS converted to Photoshop to create the White Base. I know White base can be done on Illustrator but I don't know how to do it.
Usually, a White base is a grayscale of image.....so how to do it? If I do select Filters/Colors/Convert to Grayscale I get a message saying that gradients won't be converted......

To create a white underbase in Illustrator I select everything that needs an underbase, change it to a white spot color, then use the pathfinder tool to combine and expand all objects. Then put a small stroke around the white to create a choke. This way the registration has a mm or so of flexibility so the white underbase won't peak out from the edges.

If you just need a 100% base under all colors, you can merge all color swatches and change it to 100% Black. Print it as a composite. Otherwise, you can turn each color swatch into grayscale at whatever % you want underneath that color. If you need to get trickier than that, then you can select individual objects and assign them whatever tone you require.

Issue is, supposing I have an image with gradients.... A white underbase is a grayscale inverted. HOw to convert these gradients into a grayscale and then inverte it?

"A white underbase is a grayscale inverted."
Not necessarily. Graphic programs grayscale conversion are weighted towards a result that is generally acceptable but not always optimal for a particular image. Specifically Reds, IMO, go way too dark. Always use your eyes for final judgement.
If you've created the artwork using SPOT colors and the blends as a gradients of Spot colors then changing the spot colors in the color palette to a grayscale tone will automatically change the gradients. The problem is that between SPOT colors of a blend, Illustrator will spec a 50/50 transition. If you need 100% base underneath the blend, you'd be better off, selecting that object and turning it solid black.
