Laminate Flooring Defects
Before pressing – loose stack of paper and HDF
After pressing – HDF and
paper solidified into block of cured resin
Milky
Controls – visual inspection at Press, chemistry control at Impreg, automated inspection at C/M
Bubbles trapped in resin
create milky appearance

Laminate Flooring Defects Décor mis-alignment
Printed patterns don’t line up when plank ends joined
together
Caused by saw setup issue or unexpected paper width
changes
Controls – frequent inspections, camera alignment system, Impreg dept’s control of width

Laminate Flooring Defects
White spot
Caused by damp clump in interior of HDF core; creates weak spot
during pressing
Controls – HDF manufacturer process controls, visual inspection of pressed boards and finished planks

Laminate Flooring Defects
Blow-out
Moisture issue with raw HDF boards.
Controls – moisture control during HDF manufacture; Press inspection

Laminate Flooring Defects
White line
Controls – changeover checklist, visual inspection, frequent profile measurement
Tongue profileNormal edge
Edge with “white line” defect
Caused by incorrectly positioned tooling creating “micro-bevel” along edge

Laminate Flooring Defects Overwood
Controls – assembly inspection, CMM measurement
AKA “ledging”, “proud edges”, “height difference”
