Bonjour à tous,
J'ai un petit problème: j'utilise illustrator depuis peu et lorsque j'ouvre mon document en CMJN et 300 dpi pour faire une carte de visite...
puis que je fais cette carte de visite et l'enregistre sous format pdf :
lorsque je la poste sur le site internet de l' imprimeur, on m'indique que la résolution de mon image est inférieur à 300 dpi !!!
Quelqu'un saurait- il d'où vient le problème s'il vous plaît ???
Merci d'avance !
Don't enlarge the image if you need it tobe 300 ppi. Get a larger source image instead.
Illustrator can of course resample your image to 300 ppi, but the result will probably be very blurry. In that case printing with 200 ppi might even produce the better result. But that depends on the printing process.
You might want to do the resampling using Photoshop if you have to do it at all. Photoshop has the better algorithms for it and can sharpen afterwards.

that 300 ppi setting is just the raster effects setting. The vector file itself has no resolution. What‘s in the file and with which settings exactly do you export?

Ok, thank you for your response.
In the file, there is a picture and a vector illustration that i have done for the business card.
I let you see all my setting on these screenshots:

what is the effective resolution of the picture?

À la base, l'image est en 300dpi mais lorsque je l'agrandi dans illustrator, sa résolution diminue et passe à environ 200dpi. Je crois que c'est cela le problème. Comment enregistrer un pdf en 300dpi avec illustrator dans ce cas la s'il vous plaît?

Dites moi, cela ne causera pas de problème à l'impression si mon fichier illustrator contient des photos à 300 dpi et d'autres à plus de 300 dpi? Sachant que mon imprimeur demande des images à 300 dpi.

It depends on how much over 300 ppi. If resolution is way too high this will cause 2 problems: the file gets too big. The images might get blurry.
Please do talk to your printer. It's important. Ask them how much resolution they really need.
It also depends on what is on the photos. Just the blue sky doesn't need that mich resolution. A tree with fine branches against a white sky will need a higher resolution.
