My printing supplier has a limit of total ink coverage of 240%. As I read from web resources, some may accept up to 260% or even 280%.
I wonder how it is possible to print something with TIC as high as 350%?
Recently I have received an artwork from a client with a background black color of C86 M85 Y79 K100.I requested him to change the black to either K100 or a combination with TIC < 240%.
However, he insisted to use the exact color value as "its a quality control color and stuff".
He said his existing printer has been printing his previous jobs with these color values.
I wonder how practical is it to do so.
