Concentric screening profile

[gordo]

Thanks all for the Mark Samworth @ Esko contact info. I've since been in touch with him and, very strangely, he does not have a profile for Concentric that he can share. Also, he does not have a profile for a conventional AM screen at standard densities and halftone frequencies - i.e. 175 lpi - GRACoL #1 to compare with the same print condition but using Concentric screening. And, just as strange, it appears that no forum member has such profiles either.

However, he promised that sometime this Fall a GRACoL print condition profile using Concentric will be published.

Hey Gordo, its probably because with concentric we use something called presssync that has all of the profiles embedded into a rip. You should ask him about this, I think you would be very interested in it. Its pretty different then what anybody else is doing with curves.

During the development of Staccato screening when I worked at Creo/Kodak, one of the first things that we did as part of due diligence in product development was to conduct press tests to validate performance that would be the foundation for any marketing claims. One of the first tests involved color gamut differences since it had a clear impact on customer experiences with the product. Here's one example of how useful that type of information is to printers/customers:
Quality In Print: AM and FM gamuts compared - part 1 of 2
I'm just surprised that over the past 5 or so years since the release of Concentric that this sort of basic data is not available either from Esko or its customers (at least those who participate in this forum). So, because I do get questions about it through my blog and in the absence of that information coming from vendors or customers, I tried as best as I could to better understand this screening technology using Esko's published materials. My observations are posted here:
