The problem
I had business cards printed with black background extending to the edge. After cutting, a small white edge appears on some cards. The file already had bleed. Where could the problem be?
Cause and analysis
The white edge could result from misalignment during the cutting process, where the blade does not follow the intended cutting line precisely — the variability in position between samples is consistent with this cause.
The bleed margin declared in the file may be insufficient to tolerate the natural variations in sheet positioning within the cutting machine, if it does not maintain consistent precision between one cut and the next.
Misalignment of the paper during the feeding stage of the cutting machine, combined with insufficient bleed or wide cutting tolerance, could cause the white edge in different positions depending on how each sheet enters the machinery.
Solution proposed by GPX
A possible cause is paper misalignment during passage through the cutting machine — if positioning is not consistent, the blade cuts at slightly different positions, exposing white areas of the substrate.
