When everything is done, the next step is to save your work in the special Gerber files needed by the JLCPCB process (this is why we can only use EasyEDA Pro as it has the capability to add the color file information).

Open the Top Menu and select Export – PCB Fabrication File (Gerber).

Tick the Silkscreen option to export color silkscreen and then export the Gerber files.

After exporting the Gerber, the Gerber zip file will include files specifically for JLCPCB multi-color silkscreen.
