Image trace isnt always the answer.
Original Image cropped to size.
Output as Grayscale at these settings
A closer look
I will try and upload the file. It was created with version 2.1 prerelease 11.
If I can it will be warships.lbrn2
This very dark image (black cat crossing an asphalt road) is called low key.
A very light image (polar bear on snow) is called high key.
This Image is closer to low key.
The settings does a few things to adjust the image.
The gamma sets the range from light to dark original may be 100% black. And 0% light.
it is a straight line ramp from 0% to 100% black.
Changing it to .425 brings the black level down to a much lighter level, but retains the detail.
If you were to change the contrast you would warp that ramp form a central point.
Brightness moves that central point and moves it up or down that ramp.
As for the Enhancement (sharpness). Don’t know why the call it Enhancement.
The amount is overall sharpness you want.
The radius is a little tricker to explain.
The radius looks at a single pixel, each time you increment it you expand the that to incorporate another row of pixels around that single pixel. The system decides what the average density it will assign to this pixels. The bigger the radius, the more sharpness is calculated based on the amount you have set. Experiment around with the settings to see how they work.
Now for the cut/layer settings
Using GRAYSCALE
Speed will affect that you power settings are. These work for me, you machine will probably be different
The Maximum and Minimum power determines the darkest and lightest level you will engrave.
So 100% black and below wont engrave any higher than this setting.
This works for Minimum and does the same for the lightest area.
So a 0% and above wont engrave below the minimum power.
You can still apply any of the other styles Jarvis, halftone, etc.
If you can understand how all these settings work together, you have made dealing with images so much easier to get the effect you want.
I usually take select the image and do a test, stop and make a change then display and start off where I stopped. Take notes as to what you are changing. Do this until you have dialed in what works.
Then make a preset so you have a starting point for the next time.
