Our images are intended to be as versatile as possible. When an image is converted from RGB to CMYK several factors are taken into consideration. The output device, the specific inks used, the paper or film substrate, dot gain on the printing press, and many other factors have to be accounted for. You, the customer, will achieve higher quality reproduction if you apply the custom set of printing conditions to the conversion to CMYK color mode. Additionally, some output devices require images to be in an RGB color mode (color film recorders, digital to photographic printers, etc.). The most important reason that we provide images in RGB color mode is that RGB encompasses a larger gamut (total possible number of colors that are reproducible). Often, when converting digital images to CMYK the color gamut is reduced to compensate for the limitations of CMYK inks.

In some instances these low-resolution scans do not fully represent the true color and clarity of the original images. They are for editorial review and layout only. To order hi-res images or dupes please contact Bio-Images.
