@jagardn: My nozzle is normally pretty clean.
I just gave it a try and found the following to be true:
-
@AndreZA mentioned the sweet spot of the CM is not 1mm, but more about 2-3mm away from the surface. I tried that with the Evo, and it seems I always was too close. The line doesn´t really get noticalbe thicker, but every bit of distance helps reducing spidering!
- you can go down to 10psi, anything lower is as you said getting noticable worse.
- I used Schmincke natural gray and going for a reduction of 1:25 does not work anymore (at least for me). The paint is soooooo transparant, that you don´t even see it on white paper! You only see it too late when it starts spidering.
- On soaking paper: A reduction of 1:10 to 1:15 works ok, even at 10psi it is more or less ok if you just move very slowly and have a brite surface you are painting on. So for details you slowly build up and are in form of an area that works. For anything like a really thing line with multiple passes and a lenght of more than 1cm I give up, but that could well be my missing skills.
- On non soaking surfaces: I couldn´t find a setup that works here. 2 Scenarios: Either too much air pressure or too wett. In both cases I´m not getting the results I would like to have. But overall on non soaking surface I got better results when not reducing too much, and keep the pressure at about 12-14psi. Looks better and less spidering.
- with the best setup I had in the last 30 minutes, I could avoid spidering, getting somehow the color intensity I´m expecting, but only if I move really slow. Moving slower > spidering, Moving quicker > dotted line
Now, having said that, this is complaining on a high level!! Maybe I´m simply expecting too much, as I don´t have any comparisson to other guns...
Even if I´m still not 100% happy, I again learnd something, which hopefully inproves my ABing! Thanks for that!
