Alignement cote à cote mais overlap couleurs

Bonjour,

 

Je suis en train de créer un document avec des patchs de couleurs.

Sur Illustrator je fais un alignement cote à cote de deux patchs, cependant lorsque j'ouvre mon pdf avec Acrobat, il y a une fine zone qui superpose les deux couleurs.

C'est minime sur Acrobat, mais lors du rippage du fichier la superposition est encore plus visible.

Savez-vous d'ou cela vient, et si je peux corriger ?

 

Merci d'avance

I did some further research into trapping. It seems that a trapping function called "TrapNet" is by default in PDF/X standards.

By exporting my document from Illustrator without this norm, I no longer have the problem.

Problem solved, thanks Monika for the hint 😉

Are you sure that they are aligned properly?

That area looks like overprinting.

Do you have trapping set up?

I've aligned them on the pixel grid, and the X;Y coordinates are correct.

I also tried using the space distribution alignment tool (space = 0), same problem.

Are you sure that there is no trapping running in either Acrobat or your RIP?
