Good test targets to check maximum printer/media/ink resolutions are available on more sites.ment-print.com
Yesterday, I just happen to have added a couple of helpful features to my improved Siemens star type of Resolution Test Target
. To print, one assigns a profile to the target and prints it without additional sharpening. To exclude any influence of the paper profile, one can also assign the paper profile to the target and print it with the same profile, which effectively should result in no profiling taking place.
While the target is ultimately intended for testing camera resolution, it is obviously also important to know that it is printed at high resolution to begin with. As a result of some recent feedback I was confronted with the need to be able and quickly assess whether the print was indeed done at the highest quality.
Now, one cannot only determine the actual resolution (in cycles/mm) capabilities of the printer in virtually all orientations, it will also allow to quickly determine whether it achieves the maximum horizontal/vertical printing resolution (and it proves that also matt paper can resolve in excess of 300/360 PPI). What's more, it also allows to immediately see the effect that the highest resolution has on a reduced tonality accuracy (because fewer dots can be used to dither the intermediate tones) of that highest detail.
