Help! getting these lines between dark images

Hi all,

So I thought the problem was solved but the white lines are still showing up between the black lines and colours.

I have tried as said above but nothing has worked for me.
Even when selecting and deleting the stroke line between the colours.

please help!

Thank you!!
Okay, so here's the full process.

1. Drew black on white paper illustrations which we scanned in.
2. Sent the scan through photoshop to better contrast the blacks & whites and get rid of any accidental marks.
3. Saved the photoshop file and opened it in illustrator
4. Selected image > Image trace > Expand.
5. Triple clicked area outside of image and hit delete to get rid of background.
6. Selected whole image & selected : Object > live image > make
7. changed colour to CYMK and filled in the image with bucket tool.
8. Saved as .ai file
9. Opened Indesign & placed image onto card.
10. Exported file as PDF [high quality print]

Resulting files then have the lines.

I tried to change the 'stroke' to [registration] at around 0.01 size. this seemed to get rid of the white lines but also increased the thickness of the lines by quite a large amount which also seems to effect the image.

Here is examples of the line thickness change as well as the obvious white lines on the hair in the 2nd image.

ps. I hope you don't mind the content of the images, they are just a good example!
It's for a card game I kickstarted which I need to get printed very soon.
I'm really worried though that the white lines will show up in the factory print and that would be a huge problem as we are printing 1000 copies!

So you are scanning images and then autotracing them?

And then you fill the white parts?

What you can try is the automatic way of combining the outline with a correspoding fill:

select all and then in the Pathfinder panel click on Merge. This will unify all neighbouring shapes that share the same color.

Do you have Anti-Aliasing turned ON in Preferences?  Is the White line in the original?  Look at your scanner settings to see if you can reduce the sharpness in the scan.

Felix,

If the lines have one or a few specific Stroke Weights, you should be able to select one (of each Stroke Weight), then Select>Same>Stroke Weight to delete all (of the same).
