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
was that "all paper samples were repulpable within normal parameters."
would be glad to share study results with those that are interested,
send me your address or give me a call. Thank you!
