Don't worry about the paste print. Just omit it from the stencil. Mask over all the SMT components after reflow with water washable WSOL masking. Then run it thru the wave to deposit the solder. Then wash to remove masking. Or you could manually run

(Hey Cal how you doing?) I can't resist this. You can sort of do what you're hoping for but you have to be very careful. Let the component run out and let the machine get as far as it's going to go. Then go to "Software Options", "Test commands" then
