Information            

                           Boston inks are available with lightfastness, if required.

 

                           An overlacquer may be required on some gloss and coated papers

                           The heat resistance of Boston inks has been tested to 220 deg. C,

                           ink to foil on non-T/C thermal paper.  However, customers should

                           always satisfy themselves that the ink has sufficient heat

                           resistance for their particular thermal paper, especially on non-T/C.
