DeviceRGB Distiller

Brief Description

An RGB color space is any additive color space based on the RGB color model.

The RGB color model is an additive color model in which red, green, and blue light is added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

What your issue is

(You are welcome to edit this)

In the case of DeviceRGB you have selected what is called an "Additive" color space and like a computer monitor it has a broad spectrum of valid colors. On the other hand the color printing process uses a "Subtractive" color space and it has a far more restrictive spectrum of valid colors. This means that your RGB colored items may very likely have colors that simply can not be reproduced by a printing press and therefore the final printed piece may not match very closely with what you see on screen.

How to fix this issue

(You are welcome to edit this)

By converting your images and other artwork elements into CMYK color space then you will be able preview the colors on your monitor more closely to how they will look when printed. This will prevent the situation where you order printed goods based on RGB and are not happy with the final product that you will receive in CMYK.

More details

For correct printing you need to create your design using CMYK color space (the best way) or convert to the CMYK.

For сonvert to CMYK Color Space:

One fix you can perform is to change colors to make them print properly (i.e., change from a Web RGB color space to a CMYK color space). Choose Advanced>Print Production>Convert Colors. Select the colors to be converted (here Device RGB: Convert). Choose Convert from the Action pop-menu, and assign the Destination Space Profile for your printing device. Check Preserve Black Objects so any original black items will remain black when you print. Then click OK to affect the conversion. Note: This applies a global conversion.
