We have printed each symbol on self-adhesive paper (basically sticker paper @ papergraphics.com) using the big printer in the graphics room.
For reprinting in the same format as on the Aquaponics, find the printable file with the correct sizing and in-circle placement here (diameter: 34cm)
For creating a new file or using the symbols for something else, find the editable illustrator file to each sign here.
To apply the symbols printed on sticker paper, follow a similar technique to applying large pieces of vinyl.
The text is white vinyl cut in font size 139. See placement and measurements below.
