We are a large setup that is FSC certified in mulitple cities (aus). If the order is placed on FSC stock we will provide the correct logo or place it on your artwork when it arrives. Idealy cliend just indicates the location with a white panel or keyline. The logo contains our certified number and must be specific to the the stock quoted/ordered. For instance there a several different wordings for 'mixed source' depending on its use of recycled materials. While we are proofing/imposing the job we send out the page containing the logo to FSC for approval of the logo use. By the time you have signed off your proofs FSC have usually approved the logo placement and use. Only on some occassions has the placement been rejected due to guidlines not being followed closely enough. If the job is raised as FSC then all our paperwork (quoting, job bag tickets, invoicing etc) must contain the FSC logo. We have gone to conciderable time, effort and expence to become certified. We do not charge more for FSC, as it is seen as a value add and helps us market our business ahead of other non-FSC acredited print companies along with EMS (environmental management) and SGS.
