You need the ink to cure perfectly, but you can&rsquo;t mess with the strength of the glass or let the pattern start bleeding. It&rsquo;s a tricky balance. That&rsquo;s why we lean on shortwave infrared (IR) preheaters to do the heavy lifting.</p> <h2 id="keeping-the-pattern-sharp">Keeping the Pattern Sharp</h2> <p>Here&rsquo;s the problem with standard tempering ovens: they&rsquo;re often too slow. If the glass heats up gradually, the ink can migrate, leaving you with a blurry mess. Shortwave IR lamps change that. They hit the surface fast. This creates a sharp temperature jump that sets the ink in place before the rest of the thick glass even realizes it&rsquo;s getting hot. By tweaking the wattage and how you space the lamps, you can nail that curing temperature without pushing the glass to its softening point too early.</p>
