We manufacture UV-sensitive film and paper for calibrating Laser Direct Imaging (LDI) systems. Our products are called Laser Check Film and Laser Check Paper.
Expose it directly on your LDI system and see the results instantly. UV exposure produces a visible blue image immediately. No chemical development is required. Available in sheets and rolls.
Choose the Right Laser Check Material
Laser Check Film
Transparent 0.007 in. (7 mil) UV-sensitive film for LDI calibration, registration, alignment, and image verification. UV exposure produces a blue image. Choose film when transparency is useful during inspection or calibration.
Laser Check Paper
Opaque UV-sensitive paper that produces a blue image on a solid background for easy viewing. Choose Laser Check Paper when transparency is not needed.
Why LDI Calibration Matters
Accurate registration is critical in multilayer PCB manufacturing. A small alignment or imaging error can result in wasted panels, lost production time, and unnecessary cost.
Laser Check Film lets you verify LDI registration and imaging before committing production panels.
Fast, Simple LDI Registration and Calibration
NGS, Inc. developed Laser Check Film and Laser Check Paper specifically for PCB manufacturers. It integrates easily into your existing process and provides a fast way to verify registration, calibration, and image quality.

Laser Check Film FAQ
What wavelength does Laser Check Film work with?
Laser Check Film is sensitive to UV wavelengths from approximately 360–395 nm. UV exposure produces an immediate blue image.
How thick is Laser Check Film?
Laser Check Film is 0.007 in. (7 mil) thick, a familiar thickness for PCB manufacturing and LDI applications.
Does Laser Check Film require chemical processing?
No. The blue image appears immediately after UV exposure. No developer, fixer, washing, or other chemical processing is required.
Is Laser Check Film available in sheets and rolls?
Yes. Laser Check Film is available in multiple sheet and roll sizes for different LDI systems and calibration applications.
Should I choose Laser Check Film or Paper?
Choose Laser Check Film when you need transparency to inspect alignment or registration. Choose Laser Check Paper when you prefer an opaque background for viewing the exposed image. Both produce a blue image under UV exposure without chemical processing.
