Today is the first time I’ve tried engraving laser polymer stamps since my first adventures, when power settings were very different. I thought I’d revisit the process using the new settings, and let me tell you they work great!
Prepare your file as a raster engrave rather than vector engrave, to get access to the Vary Power function. Do three passes of Speed 1000, Power 100, Greyscale setting Vary Power with a minimum of 1, 225 LPI with a material height of 0.144 inches. Using these settings I created a stamp from an inverted PNG that had a bit of grey around the letters to provide a slight slope to the stamp, which supports the sides of the stamping areas. Note that the typeface I was using was kinda squiggly, so that came out in the stamp:
On another copy, applied Outer Glow layer effect with blend mode Multiply (this layer is above the Neon Glow layer), opacity 21, technique Precise, spread 9%, size 250 px, custom contour, range 43%, jitter 0%. These numbers would change depending on how large the image is.
That got me the levels of gray around the image that I was shooting for, and Outer Glow alone didn’t seem to cut it.
