Digital BW, The Print

hi 

i have the 6 tone quadtone set

 earlier i had no problems with brightness and the old workflow from
the mis site worked great ,after i bought new ink with the ( i think
double density black ) my workflow wont work anymore ,coz all prints
are now too much black .Now i search new workflows ,or better new
curves for my  epson 1200 printer ,and the epson archival matte or
maybe the ilford matte paper

i am really sorry for my english ,but i searched for hours now the
internet and i am to tired for more 

i hope somebody can help me 

greetings   fred
