Abstract: A laser engraving machine having dual quick release mirror holders is provided. The laser engraving machine comprises a machine station, a first mirror holder and a second mirror holder. The machine station has a working platform, a rail and a first laser tube. The first mirror holder is disposed on the rail and receives the laser light emitted from the first laser tube for carrying out a laser processing on the working platform when moves back and forth on the rail. The second mirror holder is composed of a second laser tube assembled on an output module, wherein the output module has a first binding portion and a second binding portion. The first binding portion detachably attaches to the rail for the second mirror holder to move on the rail. The second binding portion detachably attaches to the first mirror holder.

Abstract: A transfer-printing method of UV-digital stacked-thickness printing, which comprising following steps of: ink jetting a UV-ink on a carrier with low-adhesive-strength to the carrier to output a color-ink-layer with a mirrored-pattern and fully curing the color-ink-layer through UV-light-irradiation; ink jetting on the color-ink-layer to output a transparent-ink-layer with the same mirrored-pattern processed with gray-scale or binary-conversion, the transparent-ink-layer is divided into a plurality of regions, an inkjet-head ink jets back and forth within one region for multiple times and after ink jets the last time, cures the region through UV-light-irradiation with a low-irradiation-intensity, then the inkjet head moves forward to next region and ink jets back and forth within that region for multiple times; and pressing and transferring the transparent-ink-layer on the carrier onto a workpiece. The method can also be implemented on a foil-sleeking-pattern, such that the foil-surface of a metal-foil is transferred and presented on the workpiece.
