IRRADIATION
|
||||||||
|
|
The European Union now requires that all Tattoo pigment colours for sale
within the EU are Sterile. This is why the major pigment manufacturers
in the USA now sterilize all their colours. Irradiation
is known to change plastic, It can make soft plastics brittle by changing
it's molecular structure, some brands (starbrite, intenze, kuro sumi,
true colours etc.) of colour are still dispersed in a plastic (acrylic)
resin. Irradiation may also change the molecular structure of pigments
which may render a previously safe pigment unsafe. ACRYLIC
COPOLYMERS Many manufacturers disperse their pigments in Acrylic Copolymer. Acrylic Copolymer is a liquid plastic that will dry to a hard film in an ink or paint, this is what makes it withstand the elements and makes it waterproof. Great for ink and paint but not for Tattoo Pigment. Lets face it is not a Tattoo Artist friendly ingredient, on hot days you are faced with the need to remove the little lumps of plastic that form on your needle clusters and impede penetration, the Tattoo on the client is hard to clean up afterwards if any ink has dried on the skin. Cleaning your gear is also a hard task and if you spill any on your clients clothes you could be up for the cost of a replacement garment, as if it dries it won't wash out! But apart from that their are also health issues.
Many modern Copolymers become hard and brittle when exposed to UV radiation
over time. We have an old bottle of Starbrite ink which was left unused
for 10 years, when we shake this bottle the contents now rattle around
inside. This is because we now have a solid lump of brittle plastic inside.
The Acrylic has gone hard in storage. The same process can happen in a
Tattoo to a smaller degree over time. GLOW IN THE DARK COLOURS We will not sell glow in the dark or "black light" pigments . These pigments are made by infusing plastic (perspex) with a fluorescent dye, and then grinding the plastic to a fine powder (pigment) The dyes are water soluble so once the plastic starts to degrade due to UV degradation, 10 years or so, the dye is released and absorbed into the body leaving a brittle plastic powder under the skin. They were originally developed as a marker dye for fish. Fish have a shorter life span then people so it is not an issue (for fish!) enough said.! Pigment Dispersion Explained A PERSON SKILLED IN THE TECHNIQUES OF PIGMENT POWDER APPLICATION WILL GET GOOD RESULTS CONSISTENTLY. A PERSON SKILLED IN THE TECHNIQUES OF DISPERSED PIGMENT APPLICATION WILL GET GREAT RESULTS CONSISTENTLY. FACTS
ON COLOUR DISPERSION All pigments purchased
from a manufacturer are in the raw, unprocessed state. Although they are
sold by type and particle size, the particle size at this stage is somewhat
irrelevant as the particles are fused together into small clumps called
agglomerates. These agglomerates are formed during the manufacturing
process. The energy of simply stirring pigment into liquid is not great
enough to overcome the particle attractive forces preventing the breakup
of the agglomerates, the use of food blenders or a mortar and pestle will
not break up the agglomerates as this process requires huge mechanical
force, usually a machine called a contra-shear is used. If
the number of agglomerates isnt limited, the pigments properties
will be adversely affected (hiding power, tint strength, colour, also
you will have grit in the finished colour). Although the pigments are
manufactured to yield optimum hiding power, intensity and colour, these
basic properties may not be realized if the initial dispersion is inadequate. LIKE ALL PROFESSIONAL PRODUCTS YOU DO ACTUALLY NEED PROFESSIONAL SKILL TO USE IT CORRECTLY. The following are some exerts from our Tattoo Handbook. If you have a good, powerful machine, good professionally dispersed colour and you are getting poor results then IT IS YOUR FAULT! sorry but that is the simple truth, if your ego won't let you see this then there is probably not much future for you in this industry. However if you can accept this simple truth then there is hope for you. So what do you do, you play! yes, you need to get a friend into the studio that has lots of Tattoo work on them that needs colour and you go play. You try every different needle configuration you can think of, you try every variation of style you can imagine, you try un-splayed short points, you try splayed tapers, you tilt your machine this way and that and all the time you are taking notes of what you did and how and where you did it. You check what you did 5-7 days later. Is there a spot, just one! among all the scabs formed from overworking or the washed out underworked bits. If you can just find one spot, just one spot! where the colour is healed and is nice and bright, clean and vivid. If you can find this spot, then that is the bit you did right! Now you need to duplicate how you did that spot and you are on the way! It will not happen straight away and you may need to play around for months until you get it, but if you did it once you can do it again and when you know how, and you develop your technique to do it consistently you are there!

PIGMENT NEWS Mystic
Art Productions Limited have supplied the EU with a complete list of pigments
that it uses and pigments known to be in use by other suppliers. These
pigments in most cases, have been in use for over 20 years without problem.
However we were concerned that many pigments on the provisional list are
already known to be problematic. Some examples are: Pigment Red 108 (Cadmium
Selenide), Red 57:1 (Calcium Salt) and Red 57 (Barium Salt). WARNING If
you are purchasing colour from other sources ensure that your supplier
discloses the pigment identity on the product label. Some pigments are
dangerous! If your supplier will not disclose they may have something
to hide, beware. The days of a supplier
getting away with simply adding some alcohol and glycerin to a little
raw, secret, pigment grit and selling it as a Tattoo Ink are (hopefully)
nearly over. Modern Tattoo Ink is a highly sophisticated formulation and
its manufacture involves very specialized skills and equipment to ensure
proper dispersion and constitution. Another supplier says
that after health authorities tested colour in the Netherlands that their
colour was free of " AZO's (material that causes cancer) and other
pollution" This supplier is playing on fear to sell colour, maybe
a few Azo Dyes can cause cancer, however there are lots of Azo Dyes, and
to make a blanket statement that they cause cancer is very misleading
and irresponsible. For example Food Grade Colours such as: Tartrazine,
Quinoline Yellow, Yellow 2G, Sunset Yellow, Azorubine, Amaranth and the
list goes on, are all Azo Dyes! No supplier should sell pigment that is
carcinogenic, Azo's or otherwise. The scary thing is many suppliers don't
know or care what they are selling! In 2008 the E.U. released a list of pigments, and substances not safe for Tattooing. Also tests have been developed to ascertain the amounts of "Amines" in Tattoo colour, these are thought to cause cancer. All but one or two of the pigments used by Mystic Art to formulate Irezumi pigment ink have been tested and have been proved safe. The remaining pigments will be tested in due course, however as they are the same chemical class as pigments already tested we are absolutely confident they to will comply. Organic Pigments.
So often we are asked if our pigments are organic, the questioner usually
has a perception that if its organic its good, like organically grown
vegetables! Well some are some aren't, but when it comes to pigments,
organic is not necessarily good. One pigment with a very safe history
within the industry, White (TiO2) is a totally synthetic Pigment. The
pigments used in Tattoo are a mixture of organic, inorganic, synthetic
and naturals. Natural pigments are mainly derived from various plant matter, tree bark etc., they are sold by some companies along with iron oxides, for cosmetic Tattooing. Unlike iron oxides they are generally fleeting (not permanent) and start to fade fairly quickly. Our company deals exclusively with pigments that are suitable for Tattoo Art, with a high degree of permanence so we do not use Naturals. |
