I got grainy digital negative......

[lzhou1]

i am currently working on Pt/Pd printing. i use inkpress and pictorico film and epson 4880 in photo black. the tonality is excellent after i calibrated the curve. But the image is kinda grainy. Because i also print directly from large format in-camera film, the result i got from the digital negative is far worse than what i got from a large format film. Dose anyone has problem with grain that from negative?

Ps, i use Na2 as contrast agent, so it is because of the negative. Also, i can see grain on negative.

Thanks!!!

Are you only using photo black ink? If so, using all inks improves tonality and density.

Your paper choice may influence this too. Generally pt/pd hides any printer artefacts in paper fibres and diffusion. There is a plethora of methods and information on DPUG.
Best direct your questions and thread there.

A digital negative is just a digital image. It sounds like you have too few pixels in that image.
