Confirm the machine’s supported thermal film type, roll width, core size, film thickness, temperature range, speed control, and pressure settings. A roll can use a low-temperature adhesive and still be unsuitable if its core or width does not fit the machine. The laminator must provide enough controlled heat to activate the adhesive evenly without damaging the print. Review the equipment manual and film specifications, then run a small sample at the recommended settings. Look for clear bonding, flat output, clean edges, and consistent texture. Cloudiness, silvering, curling, weak adhesion, or surface distortion may indicate incorrect heat, speed, pressure, or material compatibility. Adjust only within the approved operating range rather than assuming a lower temperature always produces a safer result.
