Hi there...
ive been creating a very complex peice of work for a few months now..only one colour but ive used white over the top of the black (as white bg showing though eventually)whilst tryin new ideas.
Anyway...i finished and thought the best way to send this to the printers would be to group all the white (bg/paper eventually) and subtract it the art (black) so all that is left is one black vector layer, simple!
But when comparing the pre flattened one(with lots of actual white vectors on top) with the final one where everything has been subtracted to leave me with one layer... the whole image looks darker!! but its exactly the same isnt it? just instead of the white showing over the black, its now subtracted and its the white document bg showing through... so why is the orig brighter than the final one!! I printed both out to prove it and its true, one is brigther than the other!...
i dont really have a clue for setting up colours and finalising print for printers etc... but can someone explain why both results are different..cheers..
i really dont know how its look in the end now...
hope someone can shed some light on this..thanks

I think I can help, but it's very difficult to understand EXZCTLY what's happening. Can you port the before and after?

ignore the HORRIBLE spelling in my first post.
*port = post
*EXZCTLY = EXACTLY

thanks for the response!!
i dont have the file with me at the mo - im at work..
but try it yourself... type some text in a real decorative font..in white on a coloured bg...... put a bit of fine detail in there..like some thin line or small dots....
then
make a copy n paste everything.... now with the original... subtract the white details from the coloured BG so you just left with the coloured bg layer with the shapes cut out... and now compare that with the one you copied and pasted next to it where all shapes still exist ontop of the colour.... they look thicker(brighter)....yet the result of the 2 files is bscially the same.hope this helps..

I see what you mean, but I think this might just be a screen illusion. I zoomed in real close before and after and the watched the subtraction and the paths seemed to be exactly the same. Printing results in the same image on my end. I'm assuming you have the file set up in CMYK of course.

if this is going to be printed litho, the results should generally be the same, however if its just goingt o be digitally printed, you may be better off with the white over the top(by the sounds of it)
They should essentially be the same but it may be a trapping issue. With the white on top it would 'knockout and therefore adjust the trapping to make sure the ink doesnt bleed over. Without the white on top, no trapping adjustment is made so the printer will print it exactly where it should be.

does that make any sense at all? it could actually be all crap that im talking btw.
hope this helps

You're saying the colour of the form changes? Or that the detail around the edges changes, thereby making it look darker?
The former can only be the result of something like mixed shades, resolving to one after the merge - perhaps you have more than one flavour of black in there? Illy won't make up colours, unless you're flattening a gradient or layer colour mode.
The second is unavoidable, but is not as bad as first might seem - tiny changes in the small scale of vectors can sometimes lead to exaggerated artefacts when displayed on-screen.

thanks alot guys -
yeah its a strange deal.... luckily I saved previous versions where i can control all white top elements, think Im gonna leave 'em there...done a test print and looks good enough...
thanks alot for your help everyone, much appreciated..
Marychain- i thought it was a screen illusion too until I printed out, ok now tho, thanks anyways
