Setup notes and briefing numbers for Label Web.
Label web line fitment points
The Label Web specs page sets out the practical details for fitting a flash dryer into a label and narrow web setup. Check the layout, power and heater information here before matching the unit to your line.
Label and narrow web presses need dryer data that matches web width, substrate type and available press-side space. Key checks are heater face size, stand or bracket position, supply voltage, and the distance from the print station to the flash zone. PET, coated paper and pressure-sensitive stock all react differently when heat is held too long over a moving web.
Include a clear photo of the print head, the current dryer position and the path of the web before any unit is matched to the line. A quick note on line speed, ink system and repeat print length helps prevent overheat on labels with small gaps. If the line has guarding, extractor ducting or a rewind restriction, note that with the image.
Details to check before fitting
The goal is a tighter match between the dryer and the label press, not a generic heater selection. Power draw, mounting clearance and lamp or ceramic coverage need to be read together with the actual web path. Where packaging work changes from short label runs to longer web jobs, settings should be logged against the stock and ink used.
Align the details with the matching line notes and add the relevant cure log entry before widening the scope. Confirm the line details again before any unit or spare leaves for site. Dryer sizing depends on belt width, ink type and the pieces you run per hour, so list those in your message.
- Heater width matched to web width
- Mounting height checked above moving stock
- Power supply noted for the press bay
SA operating conditions on web lines
In Gauteng, dust build-up on reflectors and guards can reduce heater efficiency on narrow web equipment over time. Coastal sites around Durban and Cape Town should watch for corrosion on exposed fittings and more frequent cleaning around electrical enclosures. Older press rooms may also have limited distribution capacity, so the rated load of the flash unit must be checked against the existing board.
Frequent power interruptions matter on label work because restart heat can affect the first few metres of printed stock. Operators should recheck cure, web tracking and substrate temperature after a shutdown before the run continues. Ventilation also matters where adhesives, liners and coated stocks are processed in a smaller print room.

Information needed for Label Web
Send the press model, printable web width, stock description and the ink or coating being cured. Add the available voltage, phase, and a photo that shows space around the print station and any guarding. If a previous heater scorched liners, warped film or left under-cured ink, mention that fault clearly.
Record the heater style, output and mounting method against the correct setup with the matching line notes. Before any unit or spare is released for site, the line details should be checked again against the cure log entry and the current press layout. That avoids fitting a ceramic IR or quartz bank that does not suit the label web arrangement.
