image with transparent background, opened in photoshop

that object insert in illustrator.

 

while saving/printing to pdf :

 

Everything looks ok at first glance, but you can see the image border in the picture, there is a jump of 1 a 2 px over the whole border of the transparent image.(transparency is more than 100px that transaprency works ok)

file can be found here:

I have added a pdf to proof and show

the jump is visible in print and on pdf.

on the attached pdf there is a remarks icon where the jump occurs.

When selecting the image you can see it easily

 

pleas advise.

Its important.

 

thx a lot for every tip

    Looks like someone needs to sign up to download. Please use dropbox.com or wikisend.com or another file sharing site which doesn't have that requirement.

     

    The PSD would be better.

    Could not download your sample.

     

    Do you have a drop shadow? Illustrator cannot understand blending modes (eg: multiply) from Photoshop, like Corel Draw can, so you may be seeing a halo around that. You ned to use the multiply in the tranparency palette to get that to work, and place a duplciate copy with no blending mode on top(that copy does nto have drop shadow).

    What type of pdf profile did you use?

     

    I place PSDs with drop shadows using multiply frequently.

    there is no halo, no border or other transparency weirdness. I use PDFX-4 mostly. Above zoomed in 1200%

    http://users.ugent.be/~baverhey/illustrator.pdf

     

    il post the ai file in about 10 hours

     

    @Mike Gondek no drop shadows, no border , no effects what so ever, thats the strange thing.

    just transparent for the whole background, i hope you can see it in the pdf.

    The effect is not visable in the illustrator artbord work enviremetn.

    Wel visable in print, pdf, different pdf, print to pdf, save to adobe pdf.

    gonne try tiff and some others to night.

     

    @ MikeWenzloff : i used pdfx-1 due to printer request.

    ill try 4 tonight

     

    thx for your time

    There is no transparentie in your file.

    I can also see that the image seems to be splitup in peaces, did you flatten your file?

    And why do you save your image as a png? Its always better to save it as a native Photshop file and than link it in Illustrator.

    I started from a png image with transparent background.

    When the png is imported directly to ai the png is flattend but background is white and not transparent.

    thats why i went first to photohop with the image and than to illustrator.

    I saved as ai and pdf for print, not png.
