In 1991 a Report was issued on "Deinking Trials" conducted by the Beloit
Corporation. The evaluation included printed and coated paper
containing a
variety of UV/EB ink and coating combinations. The abbreviated
conclusion
was that "all paper samples were repulpable within normal parameters."
I
would be glad to share study results with those that are interested,
please
send me your address or give me a call. Thank you!
