Hahnemühle Photo Rag 308 and Dmax


SC P-600
Hahnemühle Photo Rag 308

Print Target: Piezography-129step-Spyder.tif
SpyderPRINT in spot-mode.

Measurements of L*;

  • Black is with P2-NU-UHD-MASTER.quad
  • Red is after linearization with PPE 2.2.1 (see screenshot) and at least 24 hours drying.

  • L* 13,93 and D(max) of 1,76 seems OK?
  • What can I do to increase the D(max)?



The 2 picoliter drop size on the P600s does limit dmax a bit

1.83 for 3880 style printers and maybe 1.78 for P600s.

You can increase the amount of K ink a bit if you want. Open the .quad in text edit and replace the last K channel row # with 65535.
