Cure log
Power Windows
Check your power window before a long run: stable supply matters for flash cure times, element life, and controller behaviour.
Not every factory feed is steady across the day. Power Windows looks at when your line can run heaters hard, when loads need staggering, and how print shops in South Africa plan around supply constraints.
Power Windows is about timing heater load around the power your plant actually sees. On a screen-print line, that means noting when supply is steady enough for repeatable flash dwell and when heavy users in the building start pulling voltage down. If this matches your shop, use the contact form and give the press and heater type.
Checks before a long heater run
- Best supply period written down
- Voltage reading logged at the press
- Flash unit or bank identified clearly
- Shift lead and site named
Read this note alongside the heater pages that match your setup. Power Windows deals with plant supply behaviour, while the catalogue covers the ScreenMaster-style flash cells, ceramic IR options, or quartz banks fitted on the line. Using both helps separate an electrical issue from a curing setting problem.
Where Power Windows affects a production week
Power Windows looks at supply stability before a long production run. If voltage is drifting, flash cure times can move, elements can take strain, and the controller may behave differently from the last job. A simple power check before loading the press helps keep the flash unit predictable.
Start with the print format, the heater type, and the hours when the line is busiest. In South African plants, supply can change between morning startup, lunch production, and late-afternoon load on the property. That shift shows up in flash cure time, recovery between pallets, and how hard operators push the controller to compensate.
A first reading near the press is worth keeping with the job notes. Record the voltage, the heater setting, and the result on the first test print before the run gets busy. That gives the next shift a baseline instead of a guess.
What the power note should show
The useful record is simple: when supply was steady, what the flash was set to, and whether cure behaviour changed across the shift. For garment and packaging lines, one dependable operating window matters more than chasing settings every hour. The aim is to keep heater load, dwell, and production pace in step with the available power.
Link Power Windows to the relevant Cure log entry before you change controller values across the whole line. If a ceramic IR head or quartz bank behaves differently from the previous job, check the incoming supply first.

SA supply patterns that change cure
Power planning in South Africa is rarely the same from one site to the next. A print room in Johannesburg can see different line behaviour from a coastal plant in Durban or Cape Town, especially when other factory equipment comes online. For long runs, it helps to map heater use around known pressure points on the property feed rather than treating the day as one fixed condition.
Coastal air changes cleaning intervals around reflectors, shields and sensor faces. Inland dust settles differently, so first prints after a stop need another look at cure consistency. After a power cut, many shops recheck flash dwell and controller behaviour before restarting the run.

Power window notes worth recording

Write down the time block, the measured supply, the heater setting, and what changed on press. That short record helps the buyer, operator, and maintenance side speak about the same event when a job is reviewed later.
