In regard to CMYK, a decades-long debate regarding single vs multiple angles and the use of halftones has only led to press struggles with poor print results. There are a few factors to be addressed, but they are all easy to employ and their positive impact on your print results will be dramatic. Basically, your fears about CMYK will be dashed and your need to sit in on seminars that ultimately confuse you are not needed.
It is flat out wrong to print using a rosette pattern (multiple angles) when you can use the proven and widely implemented Flemenco (single angle) style. Yes, all four screens share the same angle (22.5 degree angle is suggested). Choose any line screen you wish, but please note that 45 to 55 is now going to print much cleaner than any attempt at 65 line screen using a rosette pattern (multiple angles). Even before you learn a few more things to help you, if you do nothing more than simply use one angle and re-print one of your past CMYK jobs, you will see a huge improvement!
A well-executed lower line screen used on press always delivers a better result than a poorly executed higher line screen.
Print order matters, of course. Black and Magenta are the most aggressive colors in the CMYK print process. Print them first and second respectively. Now, depending on the image being warm or cool choose to print either Yellow or Cyan in print positions 3 and 4. The last color printed will represent a warm or cool image more accurately.
