Dear Mr Engqvist, there is no new standard introduced by us. The situation is as follows: Non-periodical screenings do produce higher tone value increase than AM-Screenings. That could be compensated by RIP-curves. Although we do not recommend compensations of 10% or more (because of former researches) this would be possible. The ISO 12647-2 CIELAB values for the solids can be reached in both, Am and NP screenings. But NP screenings do show different CIELAB- values between 0% and solids which cannot be corrected by Rip-curves. Therefore NP is a different printing condition than AM. That means that the separation for products printed with NP-screening has to take that fact into account. As we absolutely agree that standards have to be limited to few changing parameters we decided to choose a TVI-curve ( ISO F curve for CMY and K) that is already standardized in the ISO 12647-2. What does that mean in practice? If you know that you will use NP screening: Choose an ICC-profile based on the pertinent characterization data for your RGB-CMYK transformation. The ECI will publish such a profile. If you do use NP screening but you do not have RGB or pertinent CMYK- data: By giving the industry standardized characterization data including aim values for the press-calibration you have the chance using standardized device-links. We are sure to help the industry by establishing characterization- data for NP screenings and hope that the adoption of these will make life much easier in use of NP-screening.
