I have a 60 watt rabbit

till now I usuallly engraved in vector format and I only engraved solid black
I have a logo that needs to be shaded. the logo is around 3/4"
How do I prepare it in Corel draw?

Can I engrave it in vector format?

I tried to put a light grey color fill in Cdr and convert it to a bitmap.
after many tries it came out only half decently. the dots were too big.

I also find that whenever I engrave in bitmap format, it is not so sharp.
I mostly engrave between .1"- .4"

Can someone help me?

By the way, I usuallly engrave at a speed of 500- 750, does anyone engraveat this speed?

Your best bet is to get photograv and convert all your shading etc using this - you then bypass the lasers interpreter of shading and send the already shaded output in black and white to the laser.
You also need to make 100% sure your alignment and focus distance as well as motion system is spot on if you want less fuzzy engraving.

I am not getting photograv right now, as I am not in the market for this.
I just need one thing converted.

Your laser is not a chinese laser with a glass tube is it?

There are all sorts of good write-ups on Epilog's site which will help you when trying to do fading and gradients.

You need to be willing to experiment a lot to get results you will like. I'd keep everything as vector artwork. Then I'd engrave on some scrap material at different resolutions, speeds, and power until I found something I liked. It will eat up a lot of time but it's the only way I know to get favorable results. On simple projects you can maybe guess and get it right the first time, but on things like gradients, you need to be willing to experiment.

I looked at Epilog's site and couldnt find anything.

Do you own a chinese laser?
