with other colors there are no problems just with Neons
years ago with PS6 I had less problems with that
but with CC I cant get nice Neoncolors for printing our boxes ( I use CMYK for the printing company )
Jpeg and Tiffs on my monitor look good
any Ideas how I can adjust that ?

»Neon colors« are pretty much impossible to achieve with »CMYK« by definition and that has nothing to do with the newest Photoshop version. (edited)
If you need »neon colors« then you may have to spring for a fifth (or even more) color.

Are the images already separated to the correct CMYK space? If not do you preview them in the correctl space (Biew > Prood Setup > … and View > Proof Colors)?
In which RGB Color Space do you usually work?

Hi
Take your RGB file and then, in View > Proof Set up, set proof to to the particular CMYK profile you are using. Then turn on View >Proof Colours and View >Gamut Warning. This will show you those colours in your image that are out of gamut for the CMYK profile i.e they are not contained in the range of colours encompassed by that profile. Your neon colours will be in that range.
Your choice is then to either :
a. Use a colour that is in gamut This can be done automatically by choosing the relative or perceptual rendering intent or manually with Hue and Saturation control.
or
b. As c.pfaffenbichler said, pay for additional colours to be printed.

Hi ! Normaly we use sRGB and it looks good but when we change to CMYK it gets bad
now I tried Web Coated SWOP 2006 and it looks better after changing to CMYK
just the computer seams slower when I use that
I will try more settings and see if I can find a good one

It doesn't work this way, you cannot pick the CMYK profile that gives you the most pleasing results.
You have to talk to the printer, and find out what profile to use.
Using the wrong profile can produce very bad results.
But as others have mentioned, it is impossible to print neon colors in CMYK, this will require extra inks, and will be expensive.

Offset firms whose work is largely devoted to packaging invariably run presses that deliver more than CMYK reproduction. As @c_pfaffenbichler suggested, consider an additional cylinder when a chosen color is beyond the four-color printing ink gamut.

その印刷会社がどのような印刷方式を使うかで、再現可能な色域(gamut)がかなり違います。
もし、印刷会社がオンデマンドプリント機械を使い、「色が鮮やかな印刷」というセールストークをしているなら、CMYKに変換しないで、RGBデータをそのまま印刷会社に渡してください。
普通のオフセットプリンティングでしたら、費用を追加して、CMYKにカラーを追加してもらうしか、ネオンカラーの再現方法はありません。
