Getting a good greyscale scale images take a lot of playing around to get correct. It is hard to adjust the contrast to make the image show up correctly depending on the material. I tend to use photoshop filters to create a high b/w image with my own dithering applied.<br>
<br>When I'm testing new materials I have a checker board test pattern that I use when I'm testing new materials. (I'll have to remember to copy it and some of my other cool patterns the next time I'm over at the lab.)<br>
<br>The basic pattern I use is a 2x10 cm grid, going from 100 black to 5% black in 5 percent increments. <br><br>100, 90, 80, ... 20, 10<br> 95, 85, 75, ...15, 5<br><br>This works well when trying to find the right power/speed for rastering images.<br>

Does the print driver for the laser just need vector images in black and white? Or does it work with greyscale, as well?<br>
<br>
And how about bitmaps?<br>
<br>
