Know your vector and raster fill engraving values

One thing that I’ve struggled with when making a new design is how the various raster and vector fill values will look on the material.  To take the guess work out of it, I made an engraving sample board.  You can download this file for free from Ponoko here.

Its P1 size, I used quite a bit of vector line engraving so it will be a little expensive to print.

I use mostly black acrylic for my designs, I’ve notices that raster fill values from zero to 200 are identical on the final product.  Values from 201 to 254 will produce a crosshatch pattern with the lighter crosshatch the larger the number.  Using a raster fill value of 255 will produce no pattern.

Looking at the bamboo-blond material, I don’t see any crosshatch even at higher raster fill values, all values between 205 to 255 don’t seem to mark the material but values from zero to 204 will darken and deepen the object’s area.

Studying the black cardstock, it looks as if all values between 230 and 254 will produce a noticeable crosshatch pattern.  But values below that will only make the raster fill area deeper on the material.
