Need Help Vutek QS2000 - multilayer white not printing under 4/c areas

Have you been able to print a multi layer file in the past without issue? If so, has anything changed on the prepress/caldera side?

since the press is printing white without issue, and I’m assuming color, without issue, this indicates a rip issue. White files should be a separate layer named White_Ink.
So in illustrator you have your art layer, a layer for white ink, named appropriately
In your queue, select your 8mage file (color) select create multilayer, your second layer will be the white layer(which should still be in your input queue) select white layer in the pull down.

it sounds kind of confusing, but honestly problems printing white typically start in illustrator. The name is very specific White_Ink

 

Is the spot color showing up in the rip? In Onyx, we have it set to a light blue at 50% opacity so you know it's working.
Also, we have to have overprint fill on to make sure it doesn't omit anything underneath your spot color.
Good Luck!
