I would start by buying a monitor colour calibration device like a SPYDER
regardless of who is doing the printing, yourself at home or a print shop.
Google SPYDER. It's simple to use, fast and accurate. There are others.
If you are sending files out to a print shop send CMYK images in North
America. The preference in Europe I think is LAB. Check with your printer.
Try the US Sheetfed/un-coated profile at home or anything that matches your
paper and gets you close to your calibrated monitor image.
