Print Checklist and script

I don't have a PDF or list of things I look for to submit to this post because any time I receive artwork, it is usually subjective of what will and won't work on a job by job basis. I can recommend using InDesign's own preflight panel, but make sure to make your own custom preflights as the ones that ship with InDesign don't check for much. VIGC used to have some very vigorous preflight preferences available via their website (it is in dutch): https://www.vigc.be/vigc-live-preflight-profielen/

There is an InDesign plugin called Greenlight from circular flow that I think is along the lines of what you're after. Link is here: https://www.circularsoftware.com/apps/greenlight.html but a video explaining how it works is here: https://youtu.be/lhNBsxdPrdY?si=gFRgPTc-TPNaS1J2

I did write my own "preflight enforcer" scripts so that users couldn't print or export a PDF unless their artwork passed the preflight checklists, but the script never gained much interest so I've shelved the project for now - DM me if you want to try them out. A link to the scripts in action is here: https://youtu.be/hffI_rHR9g8?si=zARke4vMWZw5hiSl&t=12 and apologies in advance for the attempts at humour in the video.
