This is talking about the tip of the needle. Standard is round, i don't know about curved, that's kind of scary, at least I have never heard of them, however there are tapered tips as well, which is probably what your talking about. Mag needles are stacked, if there is no stack they are also called flats. For the artist, tattooing is all about technique, and depending on your technique, you may choose to use a tapered needle, or a standard round.
7 or 9 magnum or a 14 round for heavy filling such as tribal .......
You can if you need to, but I would not recommend doing this for a whole tattoo. Not that there is anything wrong with it per se, but you are taking at risk unneeded trauma to the skin with this configuration as opposed to using a nice tight Round Liner.
Outlines.
07 needle grouping Round Liner so now its not a shading needle
Choose something with meaning. When I do a tattoo I like my clients to have a tattoo that evokes certain memories or feelings. Also, insist on a good tattoo needle for the detail. I recommend these. http://www.ebay.com/itm/Bugpin-bug-pins-long-taper-11-curved-mags-round-magnums-tattoo-needles-11cm-11rm-/120811530400?pt=LH_DefaultDomain_0&hash=item1c20eda8a0
They are for fine lines and detail that's in the tattoo you can also use this needle to do awhole tattoo for lines and shading without changing needles
You place the loop of the needle over the armature bar coupling. This will be held in place with either a disposable rubber hat, or with a piece of paper towel to firmly hold the needle in place and to ensure that there is no play with the needle, which is to say that it will be loose and the needle with rattle around the armature bar coupling and it will make your line work and coloring look erratic. You will set the the bar so that the needles are on the bottom of the bar riding against the tube, not the other way around. Needles straight out of the pack are completely straight, and you will need to bend the bar of the needle a bit to make sure that the needles are completely against the tube. You will then wrap rubber bands around the machine and over the needle bar to make sure that the entirety of the needle is snug and moving around. This is something that you should know well before you ever tattoo a person, so play around on your own legs to get the feel of tattooing before you ever mark another person. Best of luck.
to do the outline on a tattoo you need a needle called a liner for instance you could use a 14 round liner. now for shading you need a shader which is another kind of needle now you can use a 14 round shader or a 14 flat mag shader that answer your question and an p.s you can get a needle any size they can go as small as 1 all the way up to a 49 flat and so on
yes . You will need some high quality tattoo needles to do the tattoo. I recommend these. http://www.ebay.com/itm/Bugpin-bug-pins-long-taper-11-curved-mags-round-magnums-tattoo-needles-11cm-11rm-/120811530400?pt=LH_DefaultDomain_0&hash=item1c20eda8a0
If your doing a full color tattoo, meaning just one shade i usually use a round shader, if you want to do transaction from light to dark i use a flat mag. Sizes all depends on what your comfortable with, for a large piece or tribal i use a 25rmag and a 5rs for tighter space. for the tip i use the same liner to fill in. but just try and see what works best for you. This is my advice I have 6 years of experience currently working as a tattoo artist. Some artist will agree or disagree with my advice.
NO
Typically "shader" refers to Round Shaders, which are set up in a round configuration. They go anywhere from 5 needles to 50 depending on how big the piece that you are doing is.
