    Hi,

    I just exported a file to PDF, tried both interactive at 144 dpi and print version to 300 dpi. Here is my issue: there is an organisation logo on there which consists of a circle with typography inside. When I export the file the circle gets what I think is best described as a ‘flat tire’, meaning some of the circle’s colour is bleeding out at the edge as a short straight line.

    The icon was placed as a photoshop PDF with transparent background and has a native resolution of 300dpi.I have tried expanding the graphic’s frame, but of no avail.

    I can think of a solution or two (like editing the image so that I use a circle in ID), but can anybody tell me what is causing this issue?

    Here is a link to a crop of the exported file:

    I am guessing that it has something to do with the PDF and how it was saved. From the look of the png, it simply looks like the imported pdf has a low res graphic, and you are seeing some of the antialiasing and “intelligence” for adjusting scaling from its original native size, whatever that was. Just because the photoshop pdf is native at 300 dpi, the logo itself may have come into photoshop as a low res graphic and it was resized inside photoshop.

    Open the logo in photoshop and see if the resolution of the logo is what you expect — at the dimensions that you will print it. If it is, save the file as a psd file and import the native psd file.

    It also just occurred to me that you didn’t say whether this prints this way or it just appears on the screen at this resolution. What I described is for the first option. For the other, try setting the display performance to high.

    Thanks for the response.

    First, my display performance is always set on high.

    The logo was taken from an AI file and was pasted into PS to edit the colours. See, there was an item with a gradient in the AI file that said something like ‘not native to this application’ or something. So instead of bothering with AI to switch the colours of that item, I put it in PS. But besides this, the circle part of the logo was a vector to begin with, pasted into a 300dpi rasterized file, so the PS PDF was surely not a low res graphic.

    The PS file looks absolutely crisp, and sort of crisp in ID.

    I printed the ID exported PDF, with an updated logo (a placed 300dpi PSD) and it looks ok-ish, not as sharp as I would have liked.

    I am wondering now, the PSD and PS PDF both had transparent backgrounds. Could it be that this is causing the jaggyness and flat tires?

      I can’t answer your general question, but the reason why the placed PSD looked ‘ok-ish’ is becuase in InDesign all vector graphics are treated as raster when coming from a Photoshop file. To maintain the vector outlines you have to export first as a PDF from Photoshop, and then import this PDF in InDesign.

    Are you saying this happens when you save a PNG out of Photoshop? Or when you export as PDF? You see this on screen or when you print?

      No David, the graphic was pasted from Ai to Ps, then rasterized. The working doc resolution was set at 300dpi, saved that to a Ps PDF. I then placed it in Id. This resulted in the ‘flat tire’ for the circle. Note: I ditched this file and don’t really intend to recreate it.

      Then the second try, I made a PSD of the logo, without the circle that got me the flat tire, only kept the lettering of the logo. When placed, it looks ok-ish, but surely not as sharp as when viewed in Ps. I printed this, and the print pretty much showed what I saw on screen (although the quality is acceptable).

      This just leads me to believe that Id doesn’t handle placed PSD’s with a transparent background that well for items that usually need a vector format (e.g. logos). Does this sound as a common issue?

    Try one more thing. I’ve had once similar trouble and noticed that when brought that particular artwork to the foreground (Arrange > Bring to Front) that helped. I don’t know why, but it happened to me. So try doing that.

      Tried, but no difference

    Well, yes… if it was originally an AI graphic, then it would be much better to keep it as a vector artwork and place it in InDesign as an AI or PDF file. Rasterized (bitmapped) images can get changed in many ways and will never be as clear or sharp as vector lines.

    Your comment about PSDs with transparent backgrounds also made me think of this old post:

    I think that was mostly fixed, but it may still be helpful.

      Huh…interesting post for sure.

      And yes, I would’ve preferred to use the vector of the logo, but because there was an item in the Ai file which colours that couldn’t be edited, I had no choice but to raster it in Ps. It was an anomaly really, I usually don’t run into these things. :)

    Hi, first post from a long time lurker :]

    I’ve seen this problem a few times; it usually occurs when down sampling if the placed graphic has a very high relative resolution.

    Resizing in Photoshop to 100% size at the target resolution fixes it.

    With the graphic shown in the first post, maybe convert the container to a circle so it clips the edge a little.
