Crown Mines
Large-format print notes for Crown Mines floors dealing with daily throughput, nozzle issues, and profile matching.
How Crown Mines runs in a normal print week
The Crown Mines page deals with large-format production issues seen on busy Johannesburg floors. It covers profile matching, nozzle-related colour shifts, and the checks needed when throughput is high.
For Crown Mines jobs, note the substrate first, then the press speed and where the machine is standing. Fine dust from the industrial area, winter dryness in Johannesburg, and stop start power conditions can shift colour and head behaviour during a long print day. These notes are aimed at FastJET, Stormjet, and Skywalker operators who need a usable print result on vinyl, banner, and paper stock.
Take the opening machine photo before any purge or wipe. A clear image of the carriage area, ink lines, and the first nozzle test gives a better record when colour drift starts after a restart. That record matters on Crown Mines sites where several operators may touch the same machine across one production cycle.
Crown Mines output pack
You get one working route for the media on hand, plus checks that match the printer condition. The note ties the ICC profile to pass count, heater behaviour, and visible nozzle faults so the next operator can repeat the setup. For a busy Crown Mines line, one stable setting set is worth more than multiple trial combinations.
Before you branch into extra testing, compare Crown Mines results against the nearest press note and one swatch record. Run a final nozzle print and a short colour strip before stock leaves for dispatch across Johannesburg. ICC work starts from a test print on your usual roll, together with the RIP version you run.

Johannesburg production conditions
Crown Mines work often means high daily metre counts, mixed operators, and stock that must move between print and finishing without much pause. An active Johannesburg production site needs notes that fit live queues, not a fresh install. Separate urgent colour faults from routine calibration updates so the machine history stays readable.
Dry inland air can shorten the gap between cleans, especially when dust builds near the capping station and encoder strip. Load-shedding and generator changeovers can also affect when you capture the first acceptable sheet after startup. Record heater values, pass mode, and ink channel behaviour at the time the print turns right, not later from memory.

Crown Mines handover notes
Send Crown Mines job notes with machine photos, printed samples, media specs, and the troubleshooting steps already taken on site. Use a subject line that identifies the printer and fault.
Save the calibration record while the sample prints, RIP settings, and media labels are still next to the printer. Keep the page with the job file so purchasing, production, and the operator can refer to the same settings when colour is questioned later. On Crown Mines work, that written trail helps when repeat runs must match an earlier batch.
