Laser Check Paper for LDI Calibration

Laser Check Paper is a UV-sensitive paper designed for calibrating and testing Laser Direct Imaging (LDI) systems. It produces an immediate visible image after exposure, allowing operators to verify registration, alignment, exposure, and image quality without chemical development.

Why Use Laser Check Paper?

Laser Check Paper is a good choice when you want an opaque, solid background rather than a transparent film. Because the paper is opaque and provides a solid background, the exposed image is easy to view against the white paper surface without seeing equipment, artwork, or other material behind it.

It provides the same fast, chemical-free way to check LDI registration, exposure, and image quality, but in a paper format that may be preferable for routine calibration, visual inspection, and applications where transparency is not needed.

Laser Check Paper FAQ

What is the difference between Laser Check Paper and Laser Check Film?
Laser Check Paper is opaque, while Laser Check Film is transparent. Paper is a good choice when you want to view the exposed image against a solid background. Film is better when transparency is useful for your inspection or calibration process.

Does Laser Check Paper require chemical development?
No. The image appears immediately after UV exposure with no developer, fixer, washing, or other chemical processing.

What wavelength is Laser Check Paper sensitive to?
Laser Check Paper is sensitive to UV wavelengths from approximately 360–395 nm and can be used with LDI systems operating near 405 nm.
