I would like to know how to eliminate the boundary wires of text boxes when I create the PDF from In Design. Appear white threads on colored backgrounds. as shown in my book ad images and colors from design to production created in In Design.

This material is a newspaper ad and they use photolithography. I informed him who rides the newspaper and he told me that these wires are recorded.

Exporting and eliminate these cash limits?

InDesign doesn't export "boundary wires of text boxes" when exporting PDF! The problem you are noticing is due to your flattening of transparency when you export PDF from InDesign (don't ever print to PDF from InDesign). Those white lines are known as transparency flattening artifacts.

Transparency is flattened when exporting PDF from InDesign if you specify a version of PDF less than 1.4. You get flattened transparency when you create PDF/X-1a, a very obsolete and inappropriate subset of PDF for printing that is very problematic with content that contains any transparency effects (including masked images, drop shadows, feathering, etc.). Best setting for PDF export from InDesign for publishing are the PDF/X-4 settings!

Thank you so much. Now the problem is to check if your RIP supports this PDF / X4

Any PDF-based RIP that is 10 years old or less (including software updates) should be able to handle PDF/X-4.

That having been said, there are many prepress “professionals” who are either ignorant of 21st century print publishing workflow best practices or act as Luddites. Any number of times when personally trying to get content printed, I encountered these types who were clueless about their RIP's support for PDF/X-4 until I had to prove to them it was.

By the way, if the printer only supports PostScript, they can always print the PDF/X-4 from Acrobat Pro using PostScript to the RIP and still get better output than use of PDF/X-1a (or any other PDF 1.3 variant).
