Fabricators mixing panels cut from different color batches on the same building elevation can produce visible color variation only apparent after installation, requiring removal and re-fabrication.
Why Color Consistency Requires Tracking Beyond Visual Matching
ACP coil material can exhibit subtle color variation between different production batches, even when nominally the same color specification — a variation that may not be visually apparent when comparing individual sheets in isolation, but becomes noticeable once panels from different batches are installed adjacent to each other on the same facade elevation.
Where Batch Mixing Enters the Fabrication Process
Without explicit batch tracking during nesting and cutting, panels destined for the same elevation can be cut from whatever sheet stock happens to be available at the time, without verification that all panels for that specific elevation originate from the same color batch — creating the conditions for visible inconsistency once installed.
Why This Problem Is Discovered Only After Installation
Color batch variation is typically subtle enough that it does not register as an obvious problem when panels are handled individually in the shop — the inconsistency only becomes visually apparent once multiple panels from different batches are viewed together on the actual installed facade, under real lighting conditions.
Assigning Panels to Elevations by Batch Number During Nesting
After explaining why color batch mixing causes visible facade inconsistency between coil runs, the fix is tracking color batch assignment explicitly during the nesting process, ensuring panels destined for the same elevation are matched to the same batch. Clad Cut V2’s color batch tracking system assigns panels to elevations by batch number during nesting, preventing the batch mixing that leads to costly post-installation color inconsistency discovery.
