  1. Very interested in testing this out. Like I said on Reddit, we haven’t had a ton of success with 4CP. The main issue on my end has been figuring out the proper way to separate files. I’ve ton quite a bit of research, but there is so much conflicting information pertaining to dot gain, color profiles, angles, etc. I was sure our last job was going to print perfect, but what came out on press was far from what I was expecting. Everything I’ve learned thus far has been completely self taught, so all this conflicting information is giving both myself and my boss some major headaches.

    These scripts seem like the perfect addition to our shop, not only to help us from creating proper 4CP seps (so we can stop getting held up on press and adjusting seps on the fly), but I hope I can break down the process and begin to learn how to manually separate images better.

    I’d love to connect over e-mail to discuss further!

      Without seeing a file that you’ve separated along with the final printed product, it would be incredibly difficult to pinpoint what problems you may be running into. If I were to guess, my first question would be in regards to the angles you’re using. If they’re off, you’re going to get into a lot of trouble. If you got the angles right, I would then want to look at your choice of line screen. The seps aren’t the only thing at work here, though as there are a plethora of variables at play from start to finish (e.g., coating techniques, emulsion used, inks used, printing techniques, etc.,) and getting them all right is important in producing a satisfactory print.

      Having said all of this, these Easy 4C scripts will get you consistent seps with the proper angles burned right into the seps themselves. Also, if you’re capable of doing the leg work and finishing up your own sep files, perhaps the Lite version is best for you guys. It has all of the LPI choices but none of the output features (e.g., save as DCS) so you can save some money there.

      I’m always down to discuss via email. You can get at me via the contacts page here.
