Scale Up
A working route for flexo scale-up on South African packaging floors, planned for teams moving beyond a single steady press line.
How Scale Up looks in an active flexo week
The Scale Up page is for packaging teams moving beyond one steady flexo line and planning for more output. It focuses on the consumables, print control and floor discipline needed when production starts expanding.
Scale Up starts with what changes when one line becomes two or three. Plate repeat, anilox volumes, ink draw-downs and drying capacity need to match across every press that will carry the same pack. Gauteng dust, Durban moisture and planned outages all shift the control points for a South African flexo job.
Capture the current setup before extra capacity is added to the schedule. A simple sheet at the machine should note tape build, impression setting, viscosity range and the approved first-off sample. That record helps operators repeat colour and dot gain when work is split across more than one press.
Multi-press control points
Expansion still needs to be measured and repeated. Set out the checks that matter when new SKUs, longer runs or shared plate sets start moving through production. Good scale-up in flexo depends on fixed standards for consumables, wash-up, registration and handover between shifts.
Use Scale Up alongside the relevant Press paths guidance and the matching Ink notes entry when a job is moving onto additional equipment. Confirm plate IDs, ink batch references and delivery paperwork before dispatch leaves with plates or consumables. Name your press and the job on it, and we will put together the consumables for the run.

South African scale-up variables
Expansion plans in South Africa often run into transport cut-offs, mixed-age press fleets and packaging plants carrying both retail and export work. A job leaving Johannesburg for coastal conversion or dispatch needs tighter labelling and batch control than a single-line repeat. Older gear in areas such as Crown Mines may also need different wash-up timing and more frequent register checks during long runs.
Humidity near the coast can alter ink behaviour and drying, especially on film work. Inland sites usually spend more time managing dust around webs, sensors and plate mounting areas. Load-shedding also changes when teams approve start-up samples, because restart conditions can shift impression and colour balance.

Information needed before expansion
Send the intended monthly volume, substrate type, print width, number of colours and the presses expected to share the work. Add any trial failures such as dirty reverse text, weak solids, misting or inconsistent lamination bond. That gives Scale Up a proper production context instead of a generic request.
Log the change on the day the job moves beyond a single line. Keep the page reference with the job record, approval sample and any buyer documentation linked to the SKU. Traceable notes matter when plates, inks and machine settings must be matched again on the next repeat order.
