Selini Certificates – Guilloche Anomaly
After a recent press pass for a highly detailed document we noticed a strange ‘banding’ effect appear from a Guilloché pattern in the design. Although this was made from uniform horizontal fine wavy lines, the finished piece appeared banded and uneven from a distance, suggesting the press was to blame. On close inspection the lines where actually printed perfectly.
After lots of head scratching we concluded this anomaly was down to minute tolerances between ink, water and paper combined with the pressure characteristics of the press.
Inevitably this job had to be cancelled and a different style of guilloche applied, we’ll post the final outcome when it’s finished.
We don’t like to make things easy!
