This is the result of a test to see how well my Epson P400 printer delineates the one pixel wide light-color striping in certain instances with some a7III cameras and its closely related sensor kin.
Given that these thin 'white' lines are created by defining/printing the areas to each side, I find it fairly remarkable that an inkjet can portray this lighter ultra-thin line at all, much less with accuracy

The digital original on the left is subsequently printed with my P400 at highest quality on Ultra Premium Glossy Photo Paper and then scanned and processed for analysis on the right side.
