Colouring the inside of engravings with Delrin

Hello everyone, I am working on a Delrin base plate project with letter engravings on the top. The material is white. Is there a procedure you follow to colour the inside of the engravings black, so the words stand out on the white background?

Hello Alex. To improve the visibility of the letter engravings on a white Delrin base plate, I recommend the ink filling method. It's a simple process where black ink is applied to the engravings and then the excess is removed, leaving the engravings distinctly colored against the white background. This method is particularly suitable for applications where aesthetics are fundamental or when the plate is used in environments where visibility is crucial.

For more industrial applications, where the plate may be subject to considerable wear, the use of additives for laser marking during the production process could offer a more durable solution. The additive makes the engraved areas become black when the laser engraves them, ensuring a longer duration even under difficult conditions.

        This is a great tip! I’ve worked a lot with Delrin and ink filling has been my preferred method to make the engravings more vibrant. It’s relatively easy and ensures a high contrast look. Also, if it’s small batches or custom pieces, it allows for a bit of flexibility and creativity.

      Ah, a final note: the application of a clear varnish on the engraved area after the ink has dried can help protect the coloring from wear if the plate is frequently handled
