Offset and Digital files should be converted to CMYK before sending to Drummond. It is best for the customer to do the conversion so they can see how well the color changes over and can make decisions if they are not happy with the results. If Drummond makes the conversion, we will be using a method that we feel is best for an overall change.
For Wide Format, files can be either RGB or CMYK. Due to better gamut offered by multi color inkjet printers, RGB works better if Drummond converts your RGB to CMYK through our rip process.
