Where can I download a colour/shade swatch that I can get printed professionally to calibrate my monitor with? I am a photographer. I want to finally be able to print my works and sell them, but I need to make sure what I see on my monitor is what will come out of the print shop. Where can I find a professional, or mock-professional swatch that shows a large range of colours and shades that I can get professionally printed out and subsequently calibrate my monitor to? I'm looking for a free image, not something I have to pay to download, so none of that.
