Purpose and description
Enable an AI agent to recognise a printing press, assess its readiness for a specified print job, and identify permitted operation, adjustment and maintenance actions.
A printing press is a machine that repeatedly transfers ink from an image-bearing surface to a substrate, directly or through an intermediate surface, under controlled contact and pressure.
It can be Classify the press by its documented image-transfer and substrate-handling mechanisms.; Check whether a proposed substrate, image area, colour sequence and run requirement fit its capabilities.; Identify required job setup, consumables and proof checks before production.; Compare sampled output with job-specific registration and image-quality tolerances.; Determine whether an adjustment, cleaning task or jam intervention is permitted in the documented operating state.; Route print defects and transport faults to appropriate inspection or maintenance procedures..
Distinguishing features
Check that the machine produces a controlled printed image on a substrate; a mechanical press that only forms, punches or compresses material does not satisfy this function.
For a contact-transfer press, identify the image carrier and the impression interface; record whether transfer reaches the substrate directly or through an intermediate surface.
Locate the substrate presentation mechanism, such as a bed, sheet feeder or web path, and explain how it positions material for image transfer.
Distinguish the press from plate-making and finishing equipment by identifying where the intended image is actually deposited on the production substrate.
Resolve equipment marketed as a digital press against an explicit registry boundary rather than assuming that pressure-based transfer or marketing terminology alone defines membership.

Printing mechanism The physical mechanism that makes the equipment a printing press and determines its process family.
An agent must identify how the press forms and transfers an image before judging compatibility or suggesting adjustments.
Image carrier and transfer
The surfaces or components that define the image and deliver it to the substrate.
Transfer path
Record the image-defining component and each transfer interface, explicitly marking components that do not apply.
- What component defines the printed image, and does it contact the substrate directly or transfer through an intermediate surface? definition
- What observed mechanism or technical documentation supports classification as this printing process? provenance
Impression geometry
The arrangement that brings the image-transfer system and substrate into the required relationship.
Impression setting
Represent the bed, platen, cylinders, screen or other relevant geometry and its process-specific adjustment limits.
- Which geometry establishes image transfer, and which settings govern pressure, clearance or contact? definition
- Which impression settings are permitted for the proposed carrier and substrate, and how are those settings verified? action
Substrate path and job fit How printable material enters, passes through and leaves the press.
A job can fit the nominal format while failing because of feed, thickness, tension or delivery constraints.
Feed and transport
Substrate admission, positioning and movement through the printing units.
Transport envelope
Record feed-format limits and the positioning or tension controls applicable to the press.

- How does the press maintain sheet position or web tension, and what evidence indicates misfeed, slip or loss of tension? definition
Printable format and delivery
The usable printing envelope and the conditions for receiving printed output.
Usable job envelope

- Can the required sides and colour sequence be printed in one pass, and what delivery conditions prevent damage to the fresh image? action
Ink, colour and output quality Ink delivery, image alignment and evidence that printed output meets the job requirements.

Ink-system compatibility
Record ink metering, compatible consumables and any drying or curing dependency.
- How is ink metered and supplied to the image carrier, and which process-specific variables require control? definition

- Which observed defects require adjustment, additional proofing or a production stop under the approved procedure? action
Press control and safe access Operating modes, drive conditions and protection around printing and transport mechanisms.
Plate changes, threading, cleaning and jam clearance place people near mechanisms whose permitted motion depends on the task.
Drive modes and readiness
Available motion modes and prerequisites for moving into production.
Mode-dependent actions
Record how manual or powered motion, utility availability and control status constrain press actions.
- Which setup, inching and production modes exist, and what motion can each initiate? definition
- What documented checks establish readiness to start after setup, a fault or an interrupted run? action

- Does an existing Vercy world model already cover this concept or a process-specific portion that should be referenced?
- Which authoritative sources establish operating envelopes and failure modes for each included press family without generalising across incompatible mechanisms?
