When the <a href="https://goldisgood.com">press</a> slows, it&rsquo;s almost always the curing step that&rsquo;s the limiter: the UV output just can&rsquo;t keep up with the cylinder speed.</p> <h2 id="what-actually-matters-under-the-hood">What actually matters under the hood</h2> <p>A UV lamp doesn&rsquo;t just fire up and hold steady by itself. The ignition circuit needs a capacitor to deliver a controlled, high-energy pulse to strike the arc. Then that same capacitor helps hold lamp voltage steady when line voltage jumps around. In a high-response UV system, the capacitor has to support fast re-strike and consistent ignition energy. Otherwise you get flicker and dropouts—and incomplete cross-linking right when you can least afford it. Spec the capacitor to match the lamp driver and reflector assembly. Go with a voltage rating that exceeds the lamp operating voltage by a comfortable margin, and size the <a href="https://o-yate.net">current</a> handling for the peak ignition demand. That’s how you keep spectral output stable—whether you’re leaning on 365nm, 385nm, or 405nm—so the ink’s photoinitiators get a predictable dose.</p>
