Engraving Cork

Cork engraves with a striking contrast. The combusted material does build up and can be quite powdery on the material. Line engraving is recommended over area engraving.

There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

Area engraving is great it you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.2-0.5mm.

Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time consuming technique if you have a lot of small details like text.

Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.

Typical Uses

Cork is commonly used for making coasters and placemats. Also ideal for certain gasket applications, shipping and spacer pads, protective backing and numerous other industrial, commercial and hobby requirements.

Environmental Information

The cork bark is ’stripped' off without killing or damaging the trees allowing new bark to grow in its place. This makes every tree a renewable source of raw material.

Adhesives, joints and fastenings

Construction adhesives will bond boards well. Follow the adhesive manufacturer's instructions for application processes.

Is cork cut with a protective paper on top or not? Can designs be washed to remove laser cutting residue?

We try to put the protective paper in the underside of the cork to prevent burning from the laser bed but it does not adhere well. We cannot offer cork cut with the paper on the top due to the fact it does not stick well. I am unsure if the residue can be washed off.

Regular white vinegar from your kitchen can be used to remove the residue. I'm surprised that they don't do this in many of the example photos on the site. It comes off super easy with vinegar.
