Questions and Answers

What are the two types of dry processing?

Photothermography (PTG) and Thermography (TG)

What is the process involved in forming an image in Photothermography (PTG)?

A laser is used to record the image signal (latent image), and then the film is heated to produce the manifest image.

How does Photothermography (PTG) differ from Thermography (TG)?

PTG uses a laser to record the image signal and then film is heated, while TG uses a modulated heat source to produce the image directly.
