Upside down die cutting problem
Cause : the wrapping paper drops during the process and there is no mark to easily see if the paper is returned to pile correctly.
Preventive action : create the mark on the edge of every single paper sheet as of the remark for all processes and increase AQL level to intensive.
Wastage of paper
Cause : workers do not remove all waste paper out properly.
Preventive action : 100% sourcing
Oil dirty

Golden line is not connected properly after wrapping
Cause : water base calendaring will create heat on surface of paper which will make paper shrink.

Paper is not flat
Cause : during process , workers push paper into the machine.
Preventive action : let workers pile paper outside machines then move paper into the machine.
