Eagle Schematic to Toner Transfer 
Eagle Schematic to Toner Transfer (Single sided)

A howto on turning an eagle schematic editor drawing into a toner transfer image for a PCB transfer. 
It will be assumed that you are already familiar with the basics of eagle and creating PCB boards using 
the toner transfer method, as well as already having a board already prepared for your schematic.

Exporting a Toner Image From Eagle

First begin by opening your *.brd file within eagle. So you see something similar to the ALL LAYERS example below..

All Layers

BOTTOM, PADS and VIAS Only

 Once you have only the BOTTOM, PADS and VIAS layers showing like above, 
 you can export it to an image.
 
 
Step 1
: In the command box, type in: DISPLAY NONE BOTTOM PADS VIAS; 
then press Enter.

Step 2
 File->Export->Image



 
Step 3
 
 
- Check "monochrome" 
- Set the resolution to 300dpi (default 150). 
- Click "Browse" and select a folder and filename with an extension. 
   *.png will suffice.
- Click "OK"



Final Results
 
As you can see, everything is all black except the VIAS. 
The image can now be fixed up using Gimp.




Editing with Gimp


Step 1

Open the image in Gimp, then go to:  Filters->Colors->Value Invert  



Now the image needs to be flipped vertically (If you were doing a 2 sided PCB) 
and horizontally before printing for toner transfer.



Step 2


- Image->Transform->Flip Horizontally - (Only required if you are doing 2 layer PCB, 
					single sided does not need this.)
- Image->Transform->Flip Vertically




The image is now ready to be printed.
