Axis control symbol meanings

Hi Print People,
when scanning some jobs especially ones with a Pantone, I get a yellow warning triangle on right hand side of scan result. Pressed the info screen but the description is difficult to understand, any explanation in laymen's terms would be grateful.

 

What information is it giving you ?

 

hi mrheidelberg, it says; 'correctable colour deviation and remaining colour deviation after optimization' ?

 

Hi. Is this the axis control 2? I believe the answer may be a simple one. When it scans a colour bar, it gives you, among other information a delta E and a delta F reading. The delta E is the correctable value- i.e. the amount by which you CAN change the colour, so the closer you get to 0 the better. The delta F is the uncorrectable amount (layman's term!) of the colour in question. In my experience, axis control is very good at four colour process, but falls down on pantone colours.This is mainly due to the transparency of the ink. On most axis control systems you have a range of stored pantone colour values. These are often inaccurate and you will have to scan in your own value for optimisation. So what the warning triangle is telling you is that your colour value is out even though it may not be! Hope this helps.

 

Thanks daprint, yeah that info helps thought at first I was doing something wrong but all good.
