Introduction: Convert a Paper Pattern to a Laserable File
But in order to do this, I'll need to convert my hand-drawn paper pattern into something that the laser will understand. If you want to do the same, you'll need the following:
- Paper pattern
Step 1: Scan Your Pattern Into CorelDRAW
First you'll have to scan your pattern. I'm working with one pattern piece at a time for simplicity's sake. Put your pattern piece face down on the scanner bed and close the lid. Open CorelDRAW and start a new blank document with a width of 24" and a height of 18" (that's the size of the laser bed). In the File menu, choose Acquire Image, then choose Acquire from the pop out menu. Scan your pattern as a black and white photo and accept the scan.
Step 2: Do an Image Trace
Now you've got your pattern scanned into CorelDRAW, but it's a raster image. Since the laser needs vector lines with a hairline thickness in order to cut, we'll need to convert the image.
From the Bitmap menu, choose Centerline Trace, then choose Line Drawing from the pop out menu. This will open the PowerTRACE window. Give the program a minute to generate your trace. Check it to make sure all is well and it didn't forget to trace anything you need. If necessary, fiddle with the controls to get a better result. Make sure the "delete original image" box is checked, then hit "OK" to accept the trace.
Congratulations, you've now got a vector drawing of you pattern! However, you aren't done yet.
Your pattern probably has some extra stuff on it that you don't want cut out. Grain line guides, numbers, and various other marks and guides need to be deleted. First select your pattern image. In the Arrange menu, choose Ungroup All. Now you can select individual pieces of your image and delete them.
Still not done yet though...
Even though this is now a vector image, the laser won't cut it unless it is set to a hairline thickness with no fill.
On the side toolbar select the icon that looks like a pen and choose Hairline Outline from the pop out menu. Then select the icon that looks like a paint bucket and choose No Fill from the pop out menu.
You now have a laser ready file! Repeat this process for any other patten pieces you've got, and don't forget to save!
We have a be nice policy.
Please be positive and constructive.
