It is critical that you follow these examples to set your images appropriately, otherwise your advertisements may not go to press in the way you intended, or fail to print at all.

A) Profiles: By default, Photoshop inserts colour profile information (ICC) into the saved image.
This information is not interpreted correctly by some versions of RIP's (Raster Image Processors) at both
newspapers and magazines when going to film or direct to plate.
To be safe, please ensure that you set profiling to match the following diagram for every image you edit.
Go to the "File" menu, and choose:

File : Color Settings : Profile Setup

1) "Embed Profiles" - all UNCHECKED

2) "Assumed Profiles" - all NONE

3) "Profile Mismatch Handling" - all IGNORE

B) Newspaper CMYK Setup: The great majority of newspaper publishers who print colour work will want users to ensure that their colour images are supplied as correctly-separated CMYK. Go to the "File" menu, and choose:

File : Color Settings : CMYK Setup

1) "Ink Options" - Set your SWOP (Newsprint) for 30% dot gain.

2) "Separation Options" - Select GCR, Black Ink Limit to 80% and Total Ink Limit to 230%

C) Magazine CMYK Setup: The great majority of magazine publishers who print colour work will want users to ensure that their colour images are supplied as correctly-separated CMYK. Go to the "File" menu, and choose:

File : Color Settings : CMYK Setup

1) "Ink Options" - Set your options for 20% dot gain.

2) "Separation Options" - Select GCR, Black Ink Limit to 70% and Total Ink Limit to 310%
