That layer alignment trick I picked up from an old blueprint set

I was struggling with layers getting out of sync on a big commercial job in Phoenix until I noticed this one drafter always put a small crosshair mark at the same coordinates on every sheet. Turns out that made it super easy to spot when a layer shifted a tiny bit between revisions. Has anyone else tried something simple like that to catch misalignments early?

Question sounds a bit dramatic doesn't it... I mean crosshairs on every sheet is fine but misalignments that tiny usually get caught in QA anyway unless you're working with a bunch of rookies who don't check their own work. Been doing this for years and honestly a 1/32 shift here or there never caused a whole job to fail. Maybe if you're doing super precision stuff like aerospace but for typical commercial work it feels like overkill.

I read a piece in a trade magazine last month that actually covered this exact issue. They did a study on a few hundred commercial print jobs and found that misalignments under 1/16 inch hardly ever caused reprints, but the real problems came from cumulative errors across multiple passes. The article mentioned that press operators who trusted their eye over crosshairs ended up with more issues down the line, not fewer. Gavin, I hear what you're saying about rookies not checking, but even experienced guys can miss a hairline shift when they're running three jobs at once. Crosshairs on every sheet take two seconds and save a lot of headache when you're stacking up colors. For my money, it's just cheap insurance that keeps the QC team from having to catch everything after the fact.

Has anyone else run into the same issue with cumulative errors across multiple passes? I feel you on this one, @gavin_reed might think it's overkill but I've seen a whole run get trashed because a shift nobody caught just kept adding up. A couple seconds per sheet is nothing if it keeps you from reprinting a 5000 sheet job.
