Latest ISO-12647-2 Tone Value Increase specifications

While reviewing the latest ISO-12647-2 standard, I was stumped by the absence of an explicit specification for each process color "dot gain"? I have read and re-read and re-re-read each relevant sections of the standard to no avail? All there "seems" to be are references to the shape of the curves and the polynomial used to determine the TVIs (shown in Table 9) but nothing to the effect that there ought to be different aim values for each process colors? I am tempted to conclude that the specified TVI numbers are "common" to all four colors? But I hate to come up to that conclusion on my own. Best / Roger Breton www.graxx.ca

Xrite i1Pro3+ review
by Scott Martin 15 Oct '19

15 Oct '19

Hey Colorsyncers. I’ve been testing the i1Pro3+ and i1iO3 table in a variety of situations for a good while now. I have a review of XRite’s i1Pro3+ you can find at: http://www.on-sight.com/xrite-i1pro3-review/ <https://www.on-sight.com/?p=71755&preview=true> I think you’ll find it addresses of some of questions I would imagine this group has: 1) When should I consider making polarized measurements? 2) What print quality differences can I expect to see with profiles made from polarized M3 measurements? 3) What print quality differences can I expect to see with the new transmissive profiling mode? 4) What's different about i1Profiler’s transmissive profiling mode that we haven’t seen before? 5) How consistent will print quality be relative to other measurement modes? 6) How consistent will print quality be if I made some profiles with the i1Pro3+, some with an iSis, and others with an i1Pro2? I’ve included some color gamut renderings and, IMO, some really important dialog about interpreting such renderings. I’ve also included some M2 and M3 profiles of the same glossy canvas media that you can download and compare for yourself. Let me know if you have any thoughts or questions about the i1Pro3+ and i1iO3 Table. Scott Martin www.on-sight.com Precise color science for printmaking professionals

Please excuse my ignorance, guys, but does that mean that the i1pro3 supports a different "instructions set" than the 2? / Roger -----Original Message----- From: colorsync-users <colorsync-users-bounces+graxx=videotron.ca(a)lists.apple.com> On Behalf Of Graeme Gill via colorsync-users Sent: Monday, October 14, 2019 1:01 AM To: colorsync-users(a)lists.apple.com >> ColorSync <ColorSync-Users(a)lists.apple.com> Cc: Graeme Gill <graeme2(a)argyllcms.com> Subject: Re: Xrite i1Pro3+ review Scott Martin wrote: > Hey Graeme!

Hi, sorry, I don't understand what the aperture has to do with it. As you know, the i1pro2 has an i1pro1 fallback compatibility mode, so it would seem a reasonable possibility that the i1pro3+ has an i1pro2 fallback mode. The change in aperture would only seem to be relevant in printing test charts. Cheers, Graeme Gill. _______________________________________________ Do not post admin requests to the list.
