Protective backing can’t be used on any mountboard material as it rips the surface when removed, meaning scorch marks will be visible on both surfaces.
Slight yellow scorch marks will visible on the surface particularly surrounding the cut lines. If supplying your own, the colour of the top surface marks will differ depending on the dyes / chlorine within the board.
Where possible, we try to float all mountboard materials on the lamella to keep contact with the laser bed to a minimum when cutting. If your artwork is particularly dense, we will need to use honeycomb which will results in reverse markings. Heat from the laser causes residues on the honeycomb to transfer back onto the material. We try to keep this to an absolute minimum using a low laser power but unfortunately it is unpreventable.
The average cutting kerf for mountboard is +/- 0.1mm (how much the laser takes away)
As a benchmark, we recommend that minimum cut widths be no smaller than the corresponding thickness of the material and no thinner than 1mm. Any smaller will make your cut outs very fragile. See more on cut widths and Kerf (how much the laser takes away.)
Laser cuts with a singed yellow / brown edge. On darker toned mount boards, this will be less visible.
Our standard engraving setting is quite shallow to keep heat build up and excessive marking on the top surface. Because mountboard can’t be masked with paper backing, very slight marks surrounding the engraved area are unpreventable.
On lighter toned mountboard the engraving is a light yellow tone. On darker tones, the engraver usually removes the top coloured layer to reveal the lighter pulp layer below which engraves with the same pale yellow / brown appearance.
We can engrave deeper than a surface marking if requested but this can cause more scorch marks around the surrounding engraved area which are irreversible.
