On Wednesday, I installed the K6 Digital Negative system on a brand new R3000 printer using WN inks. I followed the instructions that accompanied the ink/cartridges and page 32 of the Piezography Manual (updated 6/14). I shook the ink bottles before filling the cartridges. I printed a nozzle check and a QTR calibration. All looked good.
On Saturday, I decided to print 21 step wedges on Cone Type 2, Canson Rag Photo and Hahnemuhle Photo Rag. I used the appropriate P2-X800-X880-SEL-CANragPto.quad profile for each paper. At first I just wanted to see the ink color on each of these papers, but then decided to drag out the densitometer and check linearization. On Sunday, I plotted the densities using the density tab on the linearization Excel spreadsheet. For each paper the black line drifts above the pink line. The black line never drifts below the pink line. I then printed another manual nozzle check and it looks good. I tried to upload pdf files of the linearization graphs/data, but received error messages on the attachment tool. I’d be happy to e-mail you the files.
I’m guessing I may have:
- used the wrong 21 step wedge - I used the one included in the custom profiling kit - 21steps-Eye1.tif
- used the wrong profile to print the step wedge. If this is true, which profile should I use to print on matte paper (Cone 2) on a R3000 using the P2DN Method 3 ink setup?
- both 1 and 2
Any insight is greatly appreciated,
