Page colours are different

I have created a 16pp brochure using the exact same colour backgorund (Dark Blue).

However when I printed the artwork all the pages came out the right blue, except one sheet which came out a very dark blue.

Now I am completely baffled by this; what am I doing wrong in the output settings when I convett to pdf?

Because there is no way this should be happening if this is the EXACT colours I use on every other page.

Is the blue colour a spot colour, or process? as mentioned before, transparency issues can change colour quite drastically, especially when a spot colour is converted to it's CMYK values (instead of using the RIPs look-up table)

Not exactly the same but very similar.

I have a doc with the same B&W tiff (grayscale) in the background. On one page I added another layer with a CMYK eps, and for no reason, the B&W image changes.

I've been doing these for years (Spot the difference in a daily newspaper), I'm using a template I made (didn't change anything) and since the last Indd update, I get these weird tonal changes.

In the supplied sample, images 2 and 3 have the same "file" but come out different (page 3 is a "duplicate" of page 2 with the cyan added). Image 1 is a different file and comes out as the same colour/tone as 2 (as it should).

I have checked and rechecked, started from scratch, alas... there is no reason for this...

Adobe (again), something is wrong on your end.

RGB or CMYK source? Different (or no) source icc profile? Different rendering intent? Colour management settings? Output profile? Could be a lot of things, but EPS can not be colour managed, EPS is a format of the eighties and nineties of the previous century...

Do you have an object on that page with an effect (drop shadow, glow, etc.) applied? That would change the transparency and flattening on that page, which can affect color density, etc.

The PDF settings you use (especially the standard) have considerable effect on "complex" graphics that are layered, have opacity differences, etc.
