PDF has grid lines when Ai file dropped onto distiller

[ianm76573595]

Advert done in illustrator. Fonts outlined then file dropped onto the acrobat distiller... It generates weird grid lines and this seems to be a long running problem... Any ideas?

You need to check the PDF settings. If you don't want it, then don't let it produce tiles. otherwise you need to check overprint and al lthat - in Acrobat, not AI.

I didnt know you could let the distiller produce tiles for print settings... Any idea where to find them? Had to do the PDF through illustrator which makes a bigger file... Cheers for the quick reply...

Open Distiller, go to the settings menu, save your preset.

I looked in print ready file settings... All of them one by one (In distiller) Cant find tile settings anywhere... Can you screen grab please?

Why are you using Distiller at all?

Distiller is last century's workflow, so is there any reason why you are using it?

[ianm76573595]

Smaller file sizes when I drag an Adobe Illustrator EPS file onto the app window... I'll quite happily give up and just save directly out of illustrator if thats the fix though... Thank you...

[Monika Gause]

Your grid lines happen most probably due to transparency flattening. And probably already when exporting that EPS.

So you maybe want to say goodbye to your ancient workflow, which ruins the result in so many ways (transparency as well as color management).

Just out of interest... Any Adobe employees / experts got any comments on distiller error? Is it in fact old dead technology now?

Distiller is still of use, but not when creating PDF files from Adobe Illustrator.

But concerning your error: look at your PDF file at a high magnification. It may well be that the grid lines ore only preview errors.

Thank you all. The jury is out on this one... If it was possible to get hold of the old telephone support guys like we used to.

I gave up looking for a number to get through on (that actually works)...

This is expected behaviour and not a Distiller error.

See:

And look at the part: The flattening process explained
