Six stages. You are told which one your job is in, and the fourth one does not move without you.
Size, stock, weight, finish, printed sides, quantity, and production speed. Every one of those changes the price, so the figure updates as you choose — and it is always a price the desk stands behind, not one the browser worked out.
Design in Ray Beam Studio, upload a print-ready PDF, reuse a saved design, or reorder past artwork. Studio opens with the trim, bleed, and safe area already set from what you configured.
Resolution at final size, bleed, content in the trim, colour space, fonts, and transparency. Problems come back described in terms of the printed sheet, not in prepress jargon.
A proof is generated and sent to you. It is binding: approving it is what authorises the job to reach a press, and custom print is not returnable afterwards. Nothing moves until you approve.
Commercial offset or digital, depending on the run. Production days are counted from proof approval, not from when the order was placed.
Tracked, with the transit time stated separately from production time — they are different problems and conflating them is how dates get missed.

Preflight is automatic. The judgement call — whether a low-contrast image will hold on uncoated stock, whether a hairline rule will survive the press — is not.
Built to the trim you ordered, with bleed.
Not 300 dpi at thumbnail size.
RGB is converted, and the conversion shifts colour.
Nothing prints until you approve it.
