Image cross over on single page pdfs

[WendyM]

Hi,
We receive final PDF's from customers for printing.

I have a situation where the pdf's have an 'overhang' from the page next to it in Indesign.
i.e left hand page bleeds to the spine (not across it),
right hand page has white area along the spine but there is approx .25 - .5mm image (plus 5mm bleed) of the image from the left hand page.

We use Preps for the Imposition. When these pages are imposed, we get the .25 - .5mm showing up in the white area

Can anyone please help me to solve?

(Sorry we don't do any page creation here so I can't work through it, but I would love to be able to help my customers so we don't have to deal with the problems this causes)

Does the job perfect bind or saddle stitch? If perfect bind, then within Preps, you should be able to set up a custom bleed in your layout to turn off the bleed in the gutter area. Not sure exactly where, but if you highlight a left hand page, set the right bleed amount (which will be the gutter) to 0" and do the same for the right hand page (but on the right hand page, set the left bleed amount to 0". This will allow for no printing within the grind off area. If saddle stitch, Preps should already be stopping the bleed of any page at the gutter, so for it to be printing the .25" image onto the facing page is very unusual.

Are you using Independent Pages when you create your imposition?

Are you using Independent Pages when you create your imposition?

good point. if you're using a custom layout, you will HAVE to tell Preps to turn off the bleeds in the gutter!
otherwise, you're going to have the bleed from one page overlapping the other.

If the job is saddle stitched and you are getting hairlines from the cross over. Make sure the settings inside the config profiles (.cfg) you are using have the following settings.

-PRECISION:YES
-ADJUSTPRECISION:0.0000

Are you centering the pages in the template positions?

You could try a few different things. My first thought is that you may try using Pitstop to nudge the image over to the spine so that it does not wrap over to the opposite page. My second is to crop the page in Acrobat to trim one side so that the image does not show on the opposite page. Last you could offset your page centering in Preps.

Hi,

Thank you for your replies... Much appreciated.

Job finishing is loose - (so it looks worse)
Bleed is set to 0 at the spine.
Yes Preps is centering the impositions.
No we are not using independant pages.
Config settings - I have now changed these to suggested settings but this has not made any difference.
:-) at least we are doing all of the above correctly :-)


After further looking at the pdfs, (really zooming in) I think the problem is actually coming from Indesign.
When the pdf's are created as single page pdf's, the crossover is coming from there and showing up on the pdf prior to it going into Preps.
(Sorry if I set you off on a bum steer)

I have checked with the customer and she said the images were 'snapped' to the spine in Indesign.

Any further suggestions for Indesign?

You are all so sharing with your knowledge - Thank you!!!

Is the pdf the same size, plus or minus the bleed, as the Preps page? Even with the files centered in Preps it would show the contents of the next page if the pdf is smaller than the Preps page.

[WendyM]

The PDF is the same size as preps page.
I think the problems is more where Indesign splits the spread to single pages when exporting/distilling to pdf
