Anybody having problems with their ageing i1Pro2 devices? I’ve got two here that can no longer be used for certifying proofs because they can no longer read the 100 C patch correctly :( The first is a 2012 purchase that has done 5292 strip reads and the lamp lit for 17,771 seconds. The second a 2014 purchase that has done 2070 strip reads and the lamp lit for 5,868 seconds. Another 2014 purchase that has only done 230 strip reads will pass the proofs. So will a 2011 i1 Pro that has done 9,994 strip reads and 31,981 seconds of lamp use! All pass the i1 Diagnostics tests. The proofers are calibrated using an ILS30 but when we are running at high output we can’t afford to waste time pausing and auto reading each proof — so have to switch to the i1s. It looks to me that the older the i1Pro2 gets the worse it gets at measuring 100% cyan — there are no problems with any other patches. Comparing the good and bad devices in ArgyllColorMeter shows that the spectral curve for cyan is an identical shape but offset slightly. Annoying that it only takes 15 months of relatively light use before the these devices become pre-press bricks :( -- Martin Orpen Idea Digital Imaging Ltd
