: Does resolution matter even for vectors? In InDesign, I used the preflight panel to mark pics with resolution lesser than 300dpi to light up as errors. In the process, it also selected some

While it is true that vectors have no resolution because they have not yet been rasterized, it is possible that there are rasterized textures stored in the file as a component. One can make a perfectly valid SVG that only contains a JPEG image encoded as base-64 for example. This would be a vector file in name, but not in spirit. Less extreme examples would be drop-shadow effects and the like that are "baked in" rather than calculated. These are quite often used and can be poor quality when scaled.

So it is plausible any preflight software might flag such a file for some arbitrary threshold for effective resolution.
