9 Questions
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.
What is the main function of the replenishment system in Photothermography (PTG)?
Keep solution tanks full and assure proper solution concentration.
When is solution replenishment initiated in the Photothermography (PTG) system?
As film is introduced into the processor.
What is the role of the sensor in the solution replenishment process in Photothermography (PTG)?
The sensor initiates solution replenishment.
