RGB

RGB (Red, Green, Blue) is a color model commonly used for computer and television display. For example, .jpg and .gif file formats use RGB color model. The problem with data submitted in RGB is we can not be used in printing devices. Color model we use for printing is CMYK and the conversion between RGB and CMYK is ambiguous (there are different ways to do the conversion and they produce slightly different results).

If you submit your artwork in RGB we will have to convert it to CMYK and submit the new version for your approval.

This will make the manufacturing process longer, so try to avoid using RGB model in your artworks at all, if possible.
