       remover—are listed here. This
       information can help you answer
       questions about your own

       substitute products you may wish
       to try.

   Each system was tested (1) in a
controlled laboratory environment and (2)
under actual production conditions in a print
shop (a volunteer demonstration site).  The
opinions of the printers that used the
systems are documented, as are the
results of the specific lab tests.  For each
demonstration site, the type of ink used on
the screens to be reclaimed, as well as the
number and size of screens cleaned by the
facility during the demonstration project,
are listed.
   Comparing the production conditions of
your shop to those of the demonstration
site will help you assess the performance

                                                             Simple tables in each profile show which chemicals in the

                                                             regulations, such as the Clean Water Act and the Clean Air

The cost estimates listed in this section—along with
information on occupational risk and regulatory
concerns—will help you get a picture of what it
might cost to use a particular system. The costs of
each system include the basic purchase price of the
products, as well as the costs of actually using them
in a shop—labor hours required to reclaim a screen,
costs of wipes, and the volume of product needed.
   Remember, however, that these alone may not
be the only indications of what it really costs to use
a reclamation system. Other less obvious factors
can be important, too: How flammable are the
chemicals? —More flammable materials can cost
more in storage requirements and insurance
premiums. Are they regulated materials?—If so,
this can mean added  costs of staying in
compliance.  How hazardous are the chemicals to
worker health or to the environment? —Hazardous
materials can add to the expense of protecting
workers and the  environment.
                                                                              *££•" .
                                             Risk and Exposure
                                             Health risks that printers may face when using different screen reclamation
                                             chemicals are a major concern of all screen printing companies. Designing
                                             Solutions for Screen Printers presents information about specific chemicals that
                                             may be of concern in each system. While you may not be using the exact same
                                             products in your shop, your products may contain some of the same chemicals
                                             that are profiled.
                                               You can use this information to help assess the risks of your own system,
                                             identify recommended safety precautions, and find products that may pose
                                             less risk.

                                               -The Design for the Environment (DfE) Screen Printing Project is a voluntary
                                                collaboration between representatives of the screen printing industry and the U.S.
                                                Environmental Protection Agency. The goal of the Project is to provide screen printers
                                                with information that can help them run their facilities in a way that is more
                                  environmentally sound.'safe for workers, and more cost effective", "the Project focused on screen
                                  reclamation systems, and gathered information on the performance, cost, and health and environmental
                                  risk trade-offs of different reclamation systems (ink removers, emulsion removers, and haze removers).
                                  While the Project specifically examined screen reclamation systems, the partners of the Project encourage
                                  printers-to consider the environmental impact of all the products they use in their shops.
