Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
Making sure that the base white really prints to look gray, helps to make the gray in the white cars/parts. Doing this, enables you to use less black. Less is more.Typically, you might want to use a 230 on base...but print it light by passing the stroke semi fast, and not heavy on the print pressure. Heavy pressure just drives it in. Use a semi hard squeegee 70 or even a 70/90/70 if you got one on the base and top colors.Gray or a light application of the base white provides just enough white to support the top colors. Yellow for example, does not need 100% solid bright white to support it. It may only need 80-90% tint. This is why halftone underbases provide for a softer hand. Requires slightly higher mesh and not a heavy ink landown.

We are using Unimatch from Union which is almost as translucent as the four color process inks and it will not work with anything but white ubase. So white vs gray will depend on your ink system!pierre
The only tiny part I would throw in is when you start printing, do not even think you have a problem in a setup until you have printed at least 6 - 8 images. I feel that wet on wet takes a few prints for the colors to settle in for the long haul.Anyone else agree?
