Offsets
Sheetfed Unit
Sheetfed unit checks start at feeder pile height, side lay condition, and suckers that hold steady on coated and uncoated stock. On Johannesburg jobs we watch paper edge dryness, gripper timing, and spray powder levels so sheets leave the delivery without marking or set-off.
Perfecting Bay
In the perfecting bay, sheet turn accuracy matters more when lightweight text stock picks up curl through the day. Operators check transfer cylinder cleanliness, anti-setoff powder carry, and back-up registration before a long two-sided run goes back to the guillotine.
Plate Setter
The plate setter routine covers file trapping, punch alignment, and chemistry condition before plates reach press. Around Crown Mines, dust control near loading trays and processor rollers helps keep dot gain consistent and avoids remakes during a tight changeover.
Blanket Set
A blanket set needs correct packing, clean bearer contact, and a quick look for glazing after wash-up. When image areas start to ghost, we note nip pressure, blanket surface condition, and whether the stock grain is adding bounce on repeat work.
Ink Duct
At the ink duct, key settings are logged against substrate, coverage, and the first approved sheet from the console. Winter mornings on the Highveld can stiffen ink, so blade pressure, fountain roller stripes, and duct cleanliness get checked before colour chases begin.
Dryer Stack
The dryer stack is monitored for heat balance, sheet curl, and exhaust build-up on heavier coated work. If power supply shifts during a run, teams record lamp output, pile temperature, and odour at delivery to keep curing notes tied to the job ticket.
Service
Floor paths that match the week
Offset Printers briefs press bays, plate paths, and service visits for South African print floors. We keep makeready honest.
Press notes
Recent notes
First Photo
Start with a first-photo routine that shows feeder, delivery, control side and the latest printed sheet before the shift gets busy.
Cut Off Habits
Set cut-off habits around plate making, paper release, ink checks and dispatch so the press is not waiting on admin at opening time.
Coastal Care
Coastal care on offset kit means watching corrosion, paper curl and damp-store handling before salt air starts affecting registration.
Highveld Dust
Highveld dust gets into rollers, sensors and stacks quickly, so daily wipe-downs and covered stock matter more than most teams expect.
Power Windows
Plan around power windows by grouping makereadies, plate burns and long runs where supply is steadier and restart waste stays lower.
Courier Notes
Courier notes should list parcel count, substrate type, delivery site contact and any flat-pack limits so printed work arrives ready to use.
