Colorspace DeviceRGB Publisher

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

PLEASE NOTE: although graphics created and saved in RGB may look good on your monitor, they can never be used in print products. All work submitted in colour should be in CMYK. You can convert RGB colour to CMYK in many software packages and vice versa (although it is much better practice to compose the image in CMYK from the outset).

Converting to the CMYK Color Space:

Microsoft Publisher 2000

Microsoft Publisher defaults to RGB. It is easy to convert everything to a CMYK color space or to start a new document using the CMYK color space.

Use the following menu options: Tools/Commercial Printing Tools/ Color Printing and select Process colors (CMYK). Please note that all images incorporated into a layout need to be linked and not embedded in order to maintain the CMYK color space within the image. Using the following menu options does this: Tools/Commercial Printing Tools/Graphics Manager and highlight the embedded image. Click Link and click Browse to locate the original file and link to it. You will then need to send both the images and the layout file to us for printing.

Microsoft Publisher 2003-2007 or later

Select File Tab, then select Info. Select Commercial Print Settings. Select Choose Color Model, then Select Process Colors (CMYK)
