Protection papers were used by American sailors to prevent themselves from being taken off American ships and impressed into the Royal Navy. These were simple documents that described the sailor as being an American sailor. Many of the protection certificates were so general, and it was so easy to abuse the system, that many impressment officers of the Royal Navy paid no attention to them. "In applying for a duplicate Seaman's Protection Certificate in 1817, James Francis stated that he 'had a protection granted him by the Collector of this Port on or about 12 March 1806 which was torn up and destroyed by a British Captain when at sea.'"  One way of making them more specific was to describe a tattoo, which is highly personal, and thus use that description to identify the seaman. As a result, many of the later certificates carried information about tattoos and scars, as well as other specific information. This also perhaps led to an increase and proliferation of tattoos among American seamen. "Frequently their 'protection papers' made reference to tattoos, clear evidence that individual was a seafaring man; rarely did members of the general public adorn themselves with tattoos."
Removing skin with dermatom – The majority of doctors consider this method the most effective and less harsh.

If you talk to a tattoo artist about it, they'll likely be able to advise you on what will and won't look good, based on experience. Unfortunately, some of the trendiest tattoos are the most difficult to keep up over time. "There are two main reasons some tattoos age better than others: the size of the tattoo and long-term sun damage," Jordanne Le Fae, of Jordanne Le Tattoos, tells Bustle. But other little variables, like line-thickness and tattoo color, also end up making a difference.
It is commonly held that the modern popularity of tattooing stems from Captain James Cook's three voyages to the South Pacific in the late 18th century. Certainly, Cook's voyages and the dissemination of the texts and images from them brought more awareness about tattooing (and, as noted above, imported the word "tattow" into Western languages). On Cook's first voyage in 1768, his science officer and expedition botanist, Sir Joseph Banks, as well as artist Sydney Parkinson and many others of the crew, returned to England with tattoos, although many of these men would have had pre-existing tattoos. Banks was a highly regarded member of the English aristocracy that had acquired his position with Cook by co-financing the expedition with ten thousand pounds, a very large sum at the time. In turn, Cook brought back with him a tattooed Raiatean man, Omai, whom he presented to King George and the English Court. On subsequent voyages other crew members, from officers, such as American John Ledyard, to ordinary seamen, were tattooed.
The American Academy of Dermatology distinguishes five types of tattoos: traumatic tattoos, also called "natural tattoos", that result from injuries, especially asphalt from road injuries or pencil lead; amateur tattoos; professional tattoos, both via traditional methods and modern tattoo machines; cosmetic tattoos, also known as "permanent makeup"; and medical tattoos.
