Digital BW, The Print

Hi,

I just received my first roll of Crane's new Silver Rag paper. After 
putting it in the machine (Epson 4800), I discovered the Epson driver 
doesn't allow settings for 3rd party papers. Does anyone know what 
Epson paper to choose for using Silver Rag? Or is there a better way 
to do this?

Thanks,
Steve
