I am becoming very frustrated by the lack of response or rationale for a very simple problem we have with the later versions of Photoshop. We are an R&D firm out of Colorado that works with multinational central banks and press companies to supply trial graphics for currency and anti-counterfeiting purposes. Recently we have started using a resolution that exceeds 10,000 DPI to design for their presses, as such resolution is needed and used in currency to give the sharpest images possible (and thus deter counterfeiting).
Given the advances in printing technology, it seems counterintuitive for Adobe to cap resolution settings for the user when before it was never done. Why the change? We legitimately need the extra pixels for mapping and design purposes for machines that support this. Microprinting will lead to resolutions that easily surpass 10,000 DPI in the very near future so I'm not sure why Adobe thinks it's necessary to take a step backwards. If it is not possible to reintroduce a cap more in like with past versions (I believe it's like 170k DPI from CS5 and earlier), we are forced to step backwards to older versions of CS5 and before.
Please make a note of this problem and take action to fix it as I see no detriment to re-introducing a higher resolution cap that has been present on other versions of Photoshop for years.
