Computer to Plate

 

A 200 page book

 

A complete guide to the technology of CtP how it has developed over the last 10 years and how the existing plates are formulated.

 

Essential for any company involved in photochemistry at this level.

 

Expensive, but compared to the cost of reports in this field offers significantly better value.
