If the color in your Online PDF proof looks different from the supplied files, this can be for several reasons.

Please check the files you supplied for:

Your Online PDF proof has been converted to CMYK color mode in preparation for print at no charge. However the Jukebox Pre-Press team does only do a standard-value conversion, which may not be perfectly to your liking. We cannot be responsible for subpar results if you submit files with Pantone or RGB colours. You'll have more control over the appearance of your printed product if you do the color conversion yourself - so please take the time to prepare your file properly using CMYK color profile U.S. Sheetfed Coated v2

Your Online PDF proof shows a closer representation to print output than your uploaded file. However it is still just a representation, color shift of up to 10% may occur between print runs, and finished print color will differ from screen display color.

A special note about our Online Creator

The Online Creator works in RGB colors (light emitting objects such as your screen). To print your design, all RGB colors are translated into CMYK colors (for light absorbing objects such as print).

The proof you have been sent has been converted to CMYK color mode. This is the reason some colors may appear different in the PDF proof.
