If it is not too far off-topic, do the DTP20 and/or DTP22 have a UV filter or not? Thanks. -------------------------------------------- On Mon, 9/15/14, Jason J.

The comment was driven based on conversation with xrite at which time I was told "don't assume that every i1pro2 is the same, you should still check for the uv-cut-only situation as with the i1pro original." Note I do development work with the device so came into that discussion some time ago. Never saw the older 'best color' models. You say Rev.A which is pretty early. Most I've dealt with are later Rev.D. Bottomline I had wanted to answer the standing question -- no one cannot remove the filter off a uv-cut-only device.

There's no mention on their website, and all the reviews I've seen say that there is no UV filter version. > For general purpose use, you should > be able to survive with a uv-cut instrument, Only if it matches your viewing environment (UV poor), or you are using FWA free paper, or you are merely measuring to a UV excluded standard, rather than for viewing. > EFI was a big supplier of the OEM'ed > uv-cut i1's -- if you look on ebay, you will see most uv-cut units > have the EFI mark on the body. Strangely, one of the i1pro Rev A instruments I've acquired is branded "best.eye", and is UV included (no filter). Graeme Gill.
