Package files with linked assets

Package 'Brand_Relaunch.ai' with all linked images, fonts and an editable copy. Include a PDF proof at high-res and a folder 'Links' with original image files. Name the package folder 'Brand_Relaunch_Package_2026' and zip it, then upload to the shared drive and confirm fonts are included and no links are missing before I send to the agency.

I need the package to remove blockers for the agency. When packaging, generate a small checklist file inside the folder that lists missing links, font licenses that are not shareable, and any linked EPS/PS files that require conversion. Create both a fully editable package and a flattened 'for-proof' PDF so the agency can review immediately without requesting assets.

I packaged a job and confirmed links were present, but the agency says the images in the package are low resolution. I checked and the source files look fine on my machine. I can't explain whether packaging downgraded anything or if my linked files were proxies. What are the likely causes for a package to end up with low-res assets despite links present, how can I quickly verify the true resolution and color space of the packaged files, and what is the fastest corrective step that won't delay the agency's deadline?

We keep creating separate packages for each vendor and repeatedly gather the same linked assets, which wastes time and risks inconsistent versions of images and fonts. Which process change will stop multiple repackages: how should we centralize master assets, who owns the master package, and what simple naming/versioning rule will prevent duplicate efforts and keep everyone pulling the same, verified package?
