4cp seps are 100% based on, at the very least the following if not more:

- your screen mesh and screen making techniques (eom, rzs1, rzs2)
- your inks
- your dot gain and printing techniques

at the moment it would be very difficult for a separator to provide you great seps without knowing those variables.

I've used netseps before, and had good results, although with sim process separations.

I'm a little naive to four color process printing, I've never understood the "seps" as I've had the best results by just lightening the image a bunch, saturating it more, and sticking it in illustrator and printing the CMYK at all the same angle and dpi.

In something like UltraSeps a CMYK image cuts out parts of the colors from under the black and other areas, but I've always had better results just using a RGB image, having inks straight from the factory, setting expectations with the customers, and crossing my fingers it looks good

Download the CMYK values for your preferred ink set.

Load that into photoshop.  Open image in that CMYK ink profile.  Make adjustments to each channel as needed.

This is where you get alllll your control in making the print amazing.

You will need to know your dot gain and do a few in house tests before you get a feel for how the print looks on screen and on press and your normal starter adjustments...  i.e. Test Test Test...

I used to do this for shops.... most have decided its easier and more consistent to do sim-process.  Most of the time they wanted bump plates for a true red or a clean royal blue, etc....  Sim-process also will wash better than traditional CMYK inks.

Other than that, Coudray has his system set up really well.
Been in the industry since 1996.  5+ years with QCM Inks.  Been a part of shops of all sizes and abilities both as a printer and as an Artist/separator.  I am now the Ink and Chemical Product Manager at Ryonet.

Ultra Seps 4c routine turns out pretty usable files for that... I also learned the old way in Photoshop, and more often than not would prefer to go sim process.
