First off, it is called a tattoo MACHINE not a "gun," only a hack-prison tattooist would refer to at as a gun. Second, I did not say "bleed" as in blood, i said "bleed out" as in bleed out the color. Get a tattoo and then sleep on some white sheets, if you do not have an imprint of your tattoo, it was done incorrectly. This is also the reason that you should clean it with soap and hot water at least 3 times per day for the first 3 days. Healing time varies based on location, care and your personal healing capabilities. Furthermore, all tattoos should bleed, especially any type of shading or coloring. This is due to the fact that the needle pattern is larger and further spaced than a line pattern. I tend not to bleed during an outline, also an lining needle configuration and a good lining machine hit much harder and faster than a shading machine.
I am not sure how many tattoos you have personally, or how much time you have spent with tattooers, I just know through my experience an believe me, I have a lot of experience with tattoos.
