Getting bad results with profiling on durst Rho P10-250

[krystof]

Hi, I am using Caldera EasyMedia with Barbieri Spectropad and I can't achieve a good result with the gamut on regular vinyl sticker on durst Rho P10-250, where could be the culprit?

On Vutek LX3 Pro the profile turned out miles better and it was done the same way, same measuring target, same material. Even on an old Anapurna M2050 the profiles have much a larger gamut and pass a Fogra PSD A. Anyone some tips?

We are using INX LCF inks.

The shape of the gamut looks really strange. Could you compare it with Fogra39 and show us the result? I've done many profiles on with Easymedia for a Rho P10-250 but did never have this issue. Are you using a third party ink?

Sure, here it is, thanks a lot. Also it seems I did not measure a lot of colors correctly, that is really weird. Because during the measuring process there were no faults from the Barbieri. I thought it would tell me if something is wrong. Like it wants to double or even triple measure some samples especially on worse media like PVC banner.

Yeah, something looks off with the chart or the measurement. I would retry the process and maybe choose another chart. Also if you have another measurement device to try with, like a i X-rite 1 Pro or similar. Best of luck!

So I tried to create a new profile, this time on a paper board, enabled double reading and measured colors again only 86 %, might there be a problem with the Barbieri device? That would be weird, because on Vutek and Anapurna the profiles turned out great. I am really clueless now. We are using INX inks on all printers.

Could you share a screenshot of the linearization as well? Also could you maybe attach the icc-profile here? (You can save it on the desktop in Easymedia).

Here you go, thanks a lot.

ICC profile was too large to attach to this message so I uploaded it on wetransfer.

Hi, the linearization looks good. And when viewing the profile in ColorThink Pro and compare it to other standard CMYK-profiles the gamut of your profile looks quite good. I don't see any bumps or other strange phenomenons. When converting from RGB (relative and perceptual) I can see some minor anomalies in the shadows (marked in yellow). But all in all the profile looks fine. It's very strange that it looks so bad in Easy Profile Gamut viewer (is it really the same profile?).
