It sure has been tough finding any information about LAMA, even from Johnson Plastics, the distributor. I bought 1 sheet in each of the four colors based on the results I've seen in the ads. The unengraved sheets look absolutely great, but even though these were for tests, I didn't want to waste too much of the material.

A salesman at Johnson passed me along to a tech who was helpful, but almost no information on the product. The only numbers he had were for a 25 watt Epilog, set at 100% power and 25% speed. At 45 watts, the thinking was to simply increase the speed proportionately for the same results.

The initial tests were pretty disappointing. Using Escher's self-portrait in the globe (lots of different contrasts), everything overburned to 60% speed. Faster than that, the image came through but without any real tonal qualities. So I went the other way on the speed/power ratio....and voila! Power is the variable.

So for a 45 watt Epilog, the setting that seemed to work best across all 4 shades of the LAMA is 100% speed / 35% power. Results are actually very nice, picking up even the smallest details and engraving in sharp tones of white. I'd like to hear if anyone else has had similar success, or if this was just Friday luck.
