The ink scratches off, smears, or won't stay cured on vinyl, film, textile, or rigid board, how do I get proper adhesion?

Cured or dried ink rubs, scratches, cracks, or peels off, or the ink beads up and won't wet out on the surface. UV prints feel tacky when undercured or crack and flake when the sheet flexes if overcured. Most often caused by substrate surface energy too low for the ink (uncoated/untreated plastics, glass, metal) so ink beads and won't wet out, among other possible causes — a full step-by-step diagnostic and fix follows below.
