Re: [ARSCLIST] CD markings
There seems a merging of technology problems here. I assumed we were
discussing recordable CDs rather than the manufactured kind. The issue I
was hoping we'd keep going on was that of how the inks may affect the white
inkjet printable surfaces and the gold reinforced ones with a true gold
reflective surface.
If they do affect them, is it only what occurs at the time of printing or
does it get worse as time passes? Testing such discs at the time they are
made and, perhaps, 6 months and a year after that time and comparing results
should give us useful information.
