View Full Version : Device question - i1pro UV Cut Filter
Through my work, I have access to an EFI ES-1000, which is really nothing more than a re-branded i1pro(Sold as a color printer profiling tool).
Device Information
Device type: i1Pro (UV CUT filter) [ Emission Reflectance Reflectance Scan ]
Serial number: 840968
Firmware version: 202
CPLD version: 2
Will the UV CUT Filter be any kind of a hindrance in using this device to do calibration work on my 32" Sharp Aquos and my new Samsung HL-61A750?
Thanks
I believe the UV Cut version of the I1 Pro is not the one used for video calibration, though I can not give an in depth explanation as to why not? I do know that the the one's that Spectracal sell with CalMan are not the UV Cut Version. Maybe change the title of your thread to be a little more descriptive and Bill or Derek will jump in here.

ZandarKoad 01-30-12, 07:48 AM I know it's a turbo necropost, but this is the exact question I'm faced with. It's just that these things go for less than 1/3rd the price of the i1 Pros.
So what's the difference between an i1 Pro and a EFI ES-1000 eye-one UVcut when it comes to display calibration?
Brian Hampton 01-30-12, 09:55 AM I have read that the UV filter is only engaged during reflective measurements.
Therefore it's only for profiling a printer.
You can read a bit about the UV filter option in google.
Gretag McBeth (sp?) charged a few hundred more for units with the UV Cut filter which was installed as a response to certain phosphors in paper. (Not visible but still able to skew a print profile.
Eventually they decided to correct for that print profiling issue using software controls and they stopped making the i1 pros with the filter.
I do believe the filter is engaged only for reflective measurements and therefore not relevant to emissive readings which is all you would use with display calibration.
(Of course.... I really "WANT" to believe that because I purchased an EFI-ES1000 with the UVcut filter installed.):o :p :cool:
Brian Hampton 01-30-12, 10:04 AM Found this in an even older AVS post...
QUOTED -
This question has been asked a few times, if the UV cut filter on an I1 would affect readings when doing calibration..
Spectra-cal stated it would...
However I posed the question to X-rite and this is the response I recieved from them:
Product: i1Pro
Symptom: Does UV filter affect emissive readings?
Proposed Resolution: No, the UV-cut filter in the i1Pro is specifically designed to allow emissive measurements to pass through. You will get an accurate monitor calibration with or with out the filter.
At this point I do not know who to believe, the manufacturer of the product, or the people selling calibration software.. at the time when I was purchasing calman, I had access to an i1pro with the uv-cut filter.. I had asked spectracal if I could use the meter and was told no, and so I ended up purchasing an i1d2 from them along with the software... was I fed this line just to increase my purchase?
I have since ditched my i1d2 as it always read reds very high, and calibrated using an i1pro wih uv-cut (I have access to several of them, some brand new and some used) and always had good consistent results..

Great, so does this mean the UVcut versions can also be sent in and receive the NIST certification?
Brian Hampton 01-30-12, 05:02 PM Xrite will recertify them.
Spectracal will only recertify fairly new ones but offers discount replacements of older i1's
(that's what I heard, they may comment.)
I have no idea how old my efi es-1000 is though it is rev d. I wonder if it's age can be approximated by serial number.

For the record, a response from Spectracal on this topic:
The EyeOne Pro with UV cut-off cannot be recertified in our labs. The UV cut-off filter is not appropriate for use in video calibration so we do not process them at all in our labs. X-Rite is still able to recertify this meter directly.
So there's a contrary opinion as to the meter's efficacy.

If you've been here for a while you'll understand.

I have and I do. I'm contacting X-Rite...
Edit: Just to clarify, I'm not a cheapskate. I'm just very anxious (excited) to start calibrating as soon as possible with the budget I have as it slowly builds.
Brian Hampton 02-04-12, 07:57 PM When it comes to calibration,... there's always the temptation to go the cheapest possible route. I'm not sure why.
To me, I was never interested in having someone else "perform" a calibration because it was something I wanted to study and learn.
I have used projector's since 1999 and no matter what they are never plug and play. Setting them up is fun.
I bought an EFI ES-1000 and it happens to be UV CUT and I'm very happy with it. Finally I can measure colors with confidence and I can create a XYZ matrix to use with my Display2.
I think, for me, it was a much better route then getting a Display3 or whatever and being pretty much in the same place. (Better meter but still lots of uncertainty.)
