Getting IR Heating Right for Silk-Screened Glass

When you’re mixing screen printing with tempering, it’s all about the heat. You’re walking a tightrope: you need to dry the ink and get the glass hot enough to temper, but you can’t let the pattern blur or create stress points that’ll make the glass snap. That’s where shortwave IR lamps come in. They’re the secret to hitting that sweet spot.

Keeping Your Patterns Sharp

Here’s the real headache: ink migration. If you ramp up the heat too slowly, the ink starts to bleed. Your crisp lines turn into a smudge, and that high-gloss finish is gone. But if you just blast it with heat? You risk “skinning.” That’s when the surface looks dry, but the ink underneath is still wet. Not a good look. We use high-power density IR lamps to flash-dry the surface instantly. It locks the design in place before the glass even hits the main tempering zone. You can tweak the wattage and the distance of the lamps to control the heat flow. Higher wattage means you can speed up the conveyor, but you’ve got to make sure your timing is spot on. If the timing is off, everything else is pointless.
