Hi all,
I've seen this discussed in many forums, but I have yet to come across a satisfying solution, so I thought I'd try to find an answer.
The problem seems simple:
For the sake of discussion let's imagine a single page in inDesign with one word or graphic shape in the middle, set in black, using the default indesign 'black' swatch. This is a greyscale document, and will be sent to an off-set press for printing with no colour signatures. Just a black plate.
I export this page as a PDF and view it on screen: the text doesn't show black, but more of a grey. I thought no problem, it's just showing me an approximation or a proof black that shows how it will be on paper (if it is set in RGB, it comes out nice and black).
So to test, I open the PDF in photoshop to check the levels. Lo and behold, the black is not 100%, but 91%K.
Why is the black not black? And should I worry about this? (Images with a 100 seem to come out black just fine).
Anyone any thoughts?
Thanks in advance.
