We use the following settings within Photoshop for Trinity Mirror Newsprint Products
Our press profile Isonewspaper26v4.icc (this is the profile that must be used for picture conversion) has a dot Gain of 26% and a TAC level of 240%.
We recommend that you do not exceed 240% TAC as the printers will have set- off problems (black ink being transfered to the opposite page).
This profile must be used when converting any picture that will be printed on Trinity Mirror Newsprint.
Pictures to be cropped at a resolution of - 200ppi = 100LPI
Highlight Settings Colour - 0%-1%
Shadow Settings Colour - C59% M45% Y40% K95%- These figures are within the press profile (this gives us our 240% TAC)
Set a white point and dark point using the pipettes in the curves dialogue box (Apple M).
To assist in identifying the darkest neutral point, the info tool should display Greyscale and CMYK
modes.The highest reading in Greyscale identifies the darkest point.
You can only set the shadow while in RGB mode not CMYK as the shadow cmyk breakdown will be
incorrect.
Highlight Settings Mono - First Printing Tone 1%
Shadow Settings Mono - 95% - 97%
Every picture will also need to be accessed on an indervidual basis for the application of Sharpness due to cropped size.
We reccomend you sharpen your picture using Unsharp Mask from the Filter function.
This provides significantly more control than the other three inferior functions

Set Radius on 0.7or 0.8 for Colour pics 0.4 for Mono pics , Amount should start on 500 and reduce untill you reach your optimum visual sharpness.
Aways sharpen at 100% as any other ratio will give you a visual mis interpratation of how it will look when printed
The profile will not correct an inferior picture or dark pic etc, the picture quality is down to how you
manipulate the picture within photoshops adjustment tools.
Roll over image for before and after.
