inkjet still has dotgain. Like you said 2 printers, same picoliters, but the "splats per inch" could be different. only thing that'll change that is dotgain.No. I’m talking about picoliters since the OP is referring to inkjet printers.
I have 2 sample prints on my desk from 2 different UV printers Printer A & B are printed with the same image & resolution/DPI. same Picoliters. one looks more grainy vs the other looks more sharp.
fundamentally, that's how the canon colorado works with gloss and matte mode. ink takes longer to cure, ink droplets spread out a little more and flattens out. ever so slightly larger dots, but creates a gloss finish. VS instant curing, dots dont get time to flatten and smooth out producing a matte finish.
