Results in Image Trace don't match Live Trace

Aug 8, 2012 12:20 PM

Tags: #illustrator #cs6 #live_trace #image_trace

I just started using CS6, jumping from CS3. A major tool I use is Live Trace, and I have custom settings for that. I cannot find a way to make Image Trace behave the way Live Trace did for black and white line drawings. The results I get in CS6 are far inferior to those I got in CS3 in terms of retaining the look of the original raster image. Help would be greatly appreciated. Otherwise, I will have to leave CS3 installed just to do my Live Trace.

 

Here is a sample of what I mean. You can see the quality degredation in CS6 compared to CS3. (And it's much more obvious when it's full size and full resolution.)

My settings used in Live Trace (CS3) were:

The settings I tried in CS6 that gave the above result were:

Thanks for the help!

    My first thought is to reduce your "Threshold" settings. In CS 3 you have it at 128 but in CS6 you have 198. This might be forcing the trace to catch too much detail and thereby tracing all the pixels from the image.

    You should also try reducing the Paths and Corners settings a bit see if that helps

    And maybe you should try the Create "strokes" option too. I can't help much as I don't have a copy of CS 6 yet but those are my best guesses

     

    Give it a try and good luck

    I was able to get much closer than you're getting after just a few seconds. More time could be spent refining the trace than I spent.

     

    My trace on top... your orignal from here on bottom.

    A couple possibilities....

     

     

    1) What orginal are you using? How does it differ from the jpgs posted here (since I used the jpgs above as originals)?

     

    2) Perhaps trashing Illustrator prefernces and trying again might help.

    I've never understood why some people use Photoshop EPS files. It made sense in 1988, but it hasn't for over a decade.

     

    Glad you got it sorted!

    I am having a similar problem. Part of what I do uses Photoshop at a 1x1 pixel level. I also need to drop this in to Illustrator, Live Trace it, and then add various colors to it. Any thoughts on how I can acheive that level of corners?

    This was creating in Photoshop. I need to be able to trace it exactly to show its true form in Illustrator. This was posssible with Live Trace.

    Now its not possible with Image Trace

    This is as close as I can get

    Image trace is not particularly well at tracing black and white (1 bit) images. It' s way better with anti-aliased grayscale images.

    Thanks for trying. Here are my settings (matching your exactly) Your preset says "Fill Only 2". I'm guessing that is a user preference?

    And my results (far from yours)

    I am obviously missing something here

    I am perflexed. I have tried jpg, png, bmp (typically used for very specific reasons) and nothing.

    Thank you for trying.

    AIMSEdu, Interestingly enough when I downloaded the file from this post; 1. It was much larger than the original 2. The Image Trace worked PERFECTLY!!!

    Now, how I replicate that same scenario 20 times a day will be interesting

    Thanks again for your help!!!

    I was very dissapointed to find out that CS6 is much inferior to CS5 or earlier versions when tracing black and white line drawings or comic art. By the way many users are of the same opinion. Here is a review of CS6 vs CS5 tracing results:

    http://vector.tutsplus.com/tutorials/tools-tips/quick-tip-how-to-use-t he-new-image-trace-in-adobe-illustrator-cs6/

    And here is my own experience. Whatever settings I try in CS6 the result is just terrible. This one is the best I could get. Details are lost. Lines are very thick.

    In comparison, here is how wonderfully the same work is done by CS5, not to mention that I didn't even have to tackle with any settings at all. Just clicked the button Live Trace and got saticfactory results with the default preset.

    Traced_in_CS5_fragment.jpg

     

     

    These are original unreduced files:

    https://dl.dropbox.com/u/61392902/Illustrator%20Bugs/Original_Raster_D rawing.jpg

     

    P.S. It is sometimes possible to get good results in CS6, if you take the big drawing apart into small separate drawings. However it means a lot of additional work: tens of extra hours in a year in fact. Which, of coarse, undoubtfully means that CS6 is a step backwards if compared with CS5.

    Besides some big complex drawings with many details can not be devided into a smaller ones. And if you don't have an earlier version of the program, in this case there is no way to get a quality trace at all!

    This example, provided by unimpersonated, illustrates the deficiencies of CS6's tracing functionality perfectly.

     

    I compared the results between CS6 and CS5 using the original raster jpg posted above. It's night and day. Right out of the box with default settings, CS5 made an incredibly accurate representation. The same results were impossible to acheive with CS6 no matter how much tweaking was involved. Even cutting the original .jpg into smaller segments could not approach the accuracy attained in CS5.

     

    I have to agree, this  appears to be quite a step backwards for the tracing function in AI.

    Just wanted to add my complete agreement. I have been tracing black and white images since the times of Adobe Streamline and with CS6 there are possibly the worst ever results.

    Please Adobe please, take notice and do something about it. CS5 was excellent at it - just put that bit of code back.

    To all,

    We all seem to be having very similar issues. From this post I have disocvered that if the image that you are choosing to trace is saved as a PNG (larger than normal), PLACED into Illustrator CS6, then traced using CS6, the outcome is much better.

    I am only speaking of Black & White traces. I have not tried this in color. It hasn't been a concern of mine yet.

     

    I am in TOTAL & COMPLETE agreement with MaxCalo!!!

     

    Happy Creative!

    I downloaded and tried Illustrator CC (the newest version). Unfortunately Adobe ignored the problem. Illustrator CC still has the same deficiencies as CS6 in tracing black&white line art. Even CorelDraw does the job much better. However the best tracing software so far is Illustrator SC5. So I'll stay with CS5, hoping that the problem will be solved in future.

    I am also having a problem matching my images. This is an image I just purchased and I need it in vector format. Below is my results. How can I get a perfect tracing?

    How can I get a perfect tracing?

     

    When you do it manually.

     

    But why didn't you buy the vector version of the image? Looks like there should be one.
