Reading ink density
« on: February 27, 2018, 04:11:51 AM »

Hi everyone

Can anyone tell me how to read the ink density using i1profiler and the i1pro2 and what I should be looking for?

I'm trying to create a profile for my large format printer, i'm told I need to get the max ink density while trying to lower the amount of ink being used. i.e. if cyan is 0-100% it will currently be set at 100%, ideally, i want to lower this as much as possible while not losing anything, I believe i should be around the 70-95% mark but how do I know?

I'm told i1profiler does this and I believe there is an option but I just don't know how to determine what is correct.

Thanks

Use Measure Chart and after scanning click twice on a patch to read density values

@Czornyj

Apologies but that was as far as I got, how do I know what density value is correct for c, m, y and k?

Wait a minute - what printer, RIP, software, and what exactly are you planning to do?

Hi

I'm using a Roland Versacamm large format printer with it's own versaworks rip.

Now as standard it prints ok but trying to match your screen is a different matter and the screen is calibrated using i1profiler.

Now the guides I have found tell me I have to first limit the ink amount, to do this i'm either told to look by eye and work out when I think the colours stop changing or check the density and work it out that way.

Now I know i1profiler can measure the density but it's all just numbers to me, nothing actually makes sense and I can't seem to find any clarification.

Thanks

Scan the linearization target and check when the density/saturation
curve reach highest value, then use the patch % value for ink limiting:
