Hairlines appear when you open a PDF file in PS 6.0

Hello

Hairlines me really stressed. I know that they almost never print, but I always like to doublecheck by opening a PDF file I did through indesign, in photoshop. Normally this calm as the hairlines never appear.

BUT... they do in PS 6.0... Why is this? The same pdf open in 5.1 PS is no crack. PS 6.0 = HAIRLINES.

This seems to only happen when I did the PDF with Acrobat 4 (PDF 1.3) / PDF / X - 1a: 2001 settings - as I was told it is always safer to flatten transparencies... is this correct too?

Should I use a different compatibility?

Is there a way I can check my files once and for all for questions of hairlines before I send them off to print?

Please help... Thank you!!

This is the flattening of transparency, which causes the hairlines to appear. Here's why:

If you choose a compatibility Acrobat 5 or higher (no transparency flattening), then you will not see them.

Whether the flattening is required for your particular printer, this is what you need to ask them.
