Hi xxx

There is a limit being applied by the profile, but it is dependent on the choice of rendering intent and Black Point Compensation.

The profiles default rendering intent is perceptual. Try without “Use Black Point Compensation” Then you get 240%.

According to ISO12647-3/2005 SE - Coldset offset lithography on newsprint

4.2.7 Tone value sum

Unless otherwise specified, the tone value sum should not exceed 240% and shall not exceed 260%

NB. Should not exceed 240%, not necessarily 240%.

Maybe this will be of interest:

By John Nate - Special to Newspapers & Technology

“All of our recent testing and all the recommendations by the Newspaper Association of America and Ifra recommend using perceptual. While relative with black point of the destination works for many print environments, perceptual simply gives us better results in saturated and shadow colors today while maintaining good tonality through the printable tone range”.
