When we talk about "green" printing processes, we usually talk first about paper, then ink. At the same time, we pretty much assume that a printer has moved - or is in the process of moving - from film to CTP, avoiding the cost and chemicals of film processing. Now is a good time to take a close look at those printing plates and understand the environmental impact they may have. John Zarwan, J Zarwan Partners, has released a report that looks at the impact of conventional CTP and reduced chemistry, chemistry-free, and "processless" plates. He notes:

While environmental considerations are only one factor in choice of a plate, it is important to be aware of the differences and the amount of chemistry and other waste involved. Even if the result is not a change in plates used, an awareness of and improvement in processes and procedures is possible. It is important to remember that virtually all plates work well in the correct application, and no single solution is appropriate for every printer. Plates have different characteristics on press, different run length capabilities, and are not suitable for all applications.

Printers should be concerned about the environmental effects of their operations. They can use this document to make better purchasing and use decisions by comparing the chemistry, water, and energy requirements of each type of plate.
