One of the big reasons we ordered our GF was to be able to customize a wide range of items for our clients. Cork coasters being one of the items we sell a lot of.
I wanted to see what the laser would do directly on the cork. So in our first test, we engrave directly on the cork. Worked like a charm (see picture below), but took about 7min. to complete. We get orders ranging from 4-100s of coasters. So, 7min. per is just not efficient enough. The “char” from the laser on the coaster was also an issue. We need the final image to be water proof. You can’t really see it in the picture, but the “char” was easy to smear across the coaster. If I need a high detailed coaster for around the house…this would be a real option.
So, next was to make a rubber stamp. We ordered some low order (gray) laser rubber on Amazon and in our first attempted, we tried a very detailed sunflower image. Boy, did we learn a lot. The GF was so detailed in creating the image (which I had not altered) it was almost impossible to use as an ink stamp. The gradient color scale on the image had caused the stamp to have mountain peaks and valleys that were so details, we could not get enough ink on the stamp to ink coasters (let alone paper). It was also clear we needed to increase the power to create better definition of the image verses the stamp base (i.e. better depth).
So, back to the drawing board. I went back to the bold image we engraved directly on the coaster and created a rubber stamp using the gray rubber. As you can see in the picture, in my rush of pure joy I forgot to flip the image so it would match the first coaster…o well. This time we used a higher power setting and the depth is perfect. This rubber stamp took about 21min., but can be used over and over. We ended up making over 30 coasters for the client and the stamp was flawless.
The name at the bottom was hand stamped to show the client. They ended up using a date which we hand stamped. On bigger projects we will create a big stamp so it can all be done at once.
In the end, WOW! We are so happy with our GF. We have made several other rubber stamps since then and got it down to a science. It is so quick and easy to turn a clients idea into reality. The reason we wanted the GF in the first place!
- Each coaster is about 4.5" wide (we have a steel die to cut them out).
- The cork in the pictures is not Proofgrade.
- If anyone is wanting info on settings, let me know and would be happy to share. Just not sure if this was the place to post that info considering the cork and rubber were not Proofgrade.
