We're almost finished with artwork and need to figure out the printing part. We are interested in printing on high quality paper suitable for an old map. The paper type we are looking for should be heavy paper (e.g. 170gsm) that appears old but durable (e.g. pergamenata) like a treasure map. It should not be glossy nor feel too modern but it can be smooth. It should be able to hold quality image resolution so I don't know if rag paper would work. Do you guys have ideas? Can you suggest some printers or paper suppliers?
