[M. Lointain]

Printing skill is something that accumulates over your lifetime. I would suggest you talk to as many people as you can, read as many books as you can, do as many experiments as you can..... See if there are any good printers around you that you could watch and talk to as they print. If you can't figure out why your prints don't look as good as you want you will need to find someone who can listen to you and explain what is going wrong from your perspective. The "this is the way I do it so you should be doing it this way too" doesn't cut the mustard for improving your images. Everyone has their own little problems. One thing to keep in mind too is that there are many ways to skin a cat. If you look at many different great printers you will see that they all have their own little quirks that end up defining them. You need to find your own quirks and do what appeals to you.

Frankly for the cost of a workshop you are better off buying a ton of paper and locking yourself in the darkroom for a month, maybe even with only one neg.
