Screen Printing
Wet-on-Wet Printing
Wet-on-wet printing stacks each ink color onto the previous one without flash-curing between hits, speeding production and softening the final hand.
Wet-on-wet printing is exactly what it sounds like: the press lays down one color and the next screen prints directly on top of it while that ink is still wet, skipping the flash-cure dryer that partially gels each layer in "wet-on-dry" runs. Cutting the flash step out of every color saves several seconds per shirt, which adds up fast across a run of a few hundred pieces on an automatic press.
Buyers notice two effects from this method: faster turnaround on simple jobs, and a softer overall hand, since less total ink gets separately baked into a stiff film. A two-color logo run wet-on-wet on a jersey tee tends to feel lighter to the touch than the same design flashed between colors, though ink at the color boundaries can blend slightly where the wet layers touch.
Shops reserve this technique for low-detail spot-color designs, typically two to four colors with clean, separated shapes; anything with halftones, tight registration, or fine linework needs a flash between colors or the wet ink smears instead of stacking cleanly.
A common misconception: buyers who spot slight blending at a color edge think it's a printing defect. For a wet-on-wet job, that soft blend line is expected and normal, not something to reprint over.
