Step 1: Stick the transfer film over the plotted font press down with a squeegee or your finger. (Its already done by me, but do it again just in case.)
Step 2: Now carefully remove the lettering together with the transfer film from the carrier sheet. Be careful not to leave any letters on the carrier sheet. Letters that stick to the carrier sheet must be carefully pressed down again with the squeegee or your finger.
Step 3: Position the transfer film with the lettering onto the desired surface.
Step 4: Press the film with the lettering on. Use the squeegee or your finger.
Step 5: Pull the transfer film – without the lettering- off.
DONE :)
