OK ty guy humm i use iwata eclipse hp-sbs with createx black color (opaque) don't know if opaque is same in English sorry if is not i have a sparmax compressor at 20-25 psi i always clean my airbrush for my needles my airbrush is new i'v use maybe 4/5 time (spitting happen when i try to make very little dot or line that make little spider paw if i can say that l. for water in i dry each pieces with towel's and i shoot lot of air before starting paint. l ok im a noob and im a bit lost with that E.T lllllll maybe that can come from the needles/trigger i don't really know if i need to tight a lot or if i need to set smooth
If it's spidering then your paint is too thin or try reducing your preasure to about 15 PSI first or maybe using a transperant base will bring you paint back to life. Black and white are the hardest to get right but keep at it and you'll get there...
yeah this is hard to gauge l and no class in town im gonna take a look in downtown and my friend tell me that can be better with GOLDEN paint + golden mediums but here airbrushing is not very popular its really hard to find some stuff l and in the few store i can buy something l that cost me a leg and half arms l so ty for your help all its appreciate
If you don't tighten the nozzle cap and needle cap all the way down, it will essentially set the needle tip and nozzle further back into the airbrush. By having the tip further in, you may get paint build up on the needle cap that will blow off when you release the needle.
I only made a diagram with the needle cap moved out, but the nozzle cap not being threaded down can do the same. And together it can make a big difference in how the air/paint mix leaves the airbrush.
Mike Learn from MOJO talks about adjusting how the paint flows on the new Mojo III for more detail with this concept, http://www.youtube.com/watch?v=TH8b1LWdFgU
