Metamerism is most noticeable with black and white prints using pigment inks (such as with the Epson 2000, 2100 and 2200 printers). The vast majority of printers use dye inks which do not suffer this problem. The result of metamerism means that a neutral print might show a green or a magenta tint when viewed under different lighting. The cause of the metamerism is due to some of the colours that are contained in the mix of colours that are used to create the shades of grey. This cannot be solved using a printer profile, but needs a different printer driver program called a RIP. This controls what ink colours are used to make up the grey patterns, and eliminates the colours that cause metamerism. Unfortunately the RIP software can cost as much as the printer.
• Soft proofing. Some software such as photoshop allows you to soft-proof an image. You can see how the profile affects the image and how the printed image will look. This takes into account the gamut of the printer, and also the rendering intent of your printing software (this is discussed in the section on using printer profiles). You can then see how the out of gamut colours on the printer will be affected, and which rendering intent will be best to use.
