In general, a smooth premium white paper is the best choice for digital printing. Some ivory stocks will also give good results. Avoid recycled 'confetti' stocks and those with especially heavy textures. Talk with your printer about the 'best' stocks for the target machine. Heavier papers tend to give better results.
Moisture content can also wreak havoc with the color reproduction.
Paper should never be stored directly on concrete floors as it can pick up moisture from the concrete. If you always go to different shops, you may find that you can never 'get it right' since each printer may be set up differently or using different output devices.
