Piezography profiles using DTP70 with pro inks

What file image should I use to profile piezography pro inks if I start with the profiles for my epson 9880 printer? (256 step wedge xrite DPT70 colorbrite target?) Starting with the profiles already provided in the piezography profiles folder. I’m printing on hahnemuhle photo rag

If I understand your question you want to know which target file to use but it seems you’re self answering. You can use the dtp 256. It’s in the colorport folder. If I am misunderstanding please ask again. Just rephrase it.

Regards

Jon

Hi Jon
I have made good profiles using the 256 dtp but is it worth it to go up to the next higher step wedge (512 I believe)? Will i be able to improve my tones by doing this?
cheers
