Saw tooth strokes, making me feel down.

[oscars93987756]

Please look at the below screenshot of two pathlines, taken in Illustrator CC today,

The line of the left, when filled or stroked, produces a clean un-jaggered a.k.a. 'straight' line. So the left line is Good.

However, notice the line on the right. See how it is wobbly looking? When I fill or stoke this line, it appears not-straight, not-clean and jaggered, kinda like a saw you use to cut wood. When zoomed in, it becomes more obvious.

I have spent 3 hours using the Pen tool to change the perimeter of a font around so I can make it look more personalised. I've only noticed this problem when I finished that, and started stuffing around with grouping, fill, stroke, Object > Expand. Because I'm a moron, I didn't save my work till after I saw the above problem. Boy oh boy, maybe I'll give up and just die.

I've deselected the path and I'm left with this:

The spaced-ant-lines are all appear as jaggered when filled or stroked. The GREEN line - is a nice not-spaced-ant-line - works fine. How I ended up with some lines this and some lines that has got me depressed.

Thanks.

Hi Oscar. I see that you are having problems with a stroked path.

It Appears that you have pixel preview checked:

when that view option is selected the "saw" will look worse or better depending on the angle of the line. So 90° or 180° will look better than 45° for eg. Also the size of your artboard and zoom level will also change the saw tooth effect.

Uncheck the Pixel Preview and the edges will be perfectly crisp.

Thanks Grant,

I can't say if above solved my problem for I did solve the problem a short while ago.

Here was the solution that worked for me:

Select everything > Object > Path > Average > Clicked on both options available in the window that pops up > Ok.

This immediately made the jiggered effect go away.

I found this through trial and error. In my attempts to find a youtube video, I found that more than one youtuber was suffering the same affect, but they apparently weren't bothered by it, and not once did I see them identify my issue as an issue for them.

Youtube searches revealed Smoothing type solutions. None of which had worked.

Object > Path > Average > Clicked on both options available in the window that pops up > Ok.

The above worked for a while only.

After an hour or so, the jaggerdness has crept back in.

This time the Object > Path > Average > Clicked on both options available in the window that pops up > Ok. DOES NOT WORK anymore.

It just cumbled the whole piece of work up into a small ball.

I'm not sure if it happens when I save the file. Then open it up again. Not sure at what point the jaggerdness crept its way back into my work.

The artwork is horrible and in not presentable, despite everything else being Good.

Who has a solution to this problem?

[oscars93987756]

Pixel Preview is off and has been off throughout the whole project, but still!!! Jaggerdness creeps its way into my work. It was fine a while ago. Not I added some Outline strokes and some borders and stuff, and jaggardness has crept its was in again! Here is what I'm talking about ......

Your monitor works with pixels and when lines are not exactly horizontal or vertical, you will see jaggies. With some angles it works quite well, with others, not so much. When the artwork gets printed, you won't see jaggies. Exporting to raster files might look bad, depending on the antialiasing method you might be able to get an improvement.

Illustrators algorithm for on-screen presentation of angled lines sometimes produces inferior results to Photoshop.

Problem has been solved via switching to CPU mode, versus GPU mode.

Oscar,

Most likely far too far out, but what happens if you Ctrl/Cmd+E (to toggle between GPU and CPU, just do it again if it fails to help)?

Dear Jacob,

I go View > View using CPU = Problem Solved.
When I go View > View using GPU = Problem stays a problem.

Interesting to me is this. I saved my work when I knew lines appeared like vectors (not just were but actually appeared like straight/smooth vector lines). However, I've noticed that when copy and paste my text work onto a Shape, the Crap will appear! In order to eliminate Crap, I switch to CPU which = Problem Solved.

Thanks to Jacob, now I'm more confident that what I'm seeing on screen is I'll be getting when I spend the next 16 hours making all my variations to the same logo.

I have a new CPU and a killer graphics card NVIDEA 1000. I was under the impression that Adobe should be using my NVIDEA graphics card because it's pretty expensive little unit. I guess I'm wrong.

Is it healthy to be using my CPU in lieu of my graphics card?

Oscar,

This is what GPU is about:

Graphics cards have been included in the system requirements:

Apart from an inadequate card, the issue can be caused by lack of driver updating, lack of proper recognition of the card by the computer, and whatnot (including rifts in the space time, moon, weather, and the fact that Illy sometimes moves in mysterious ways).

Here are a few more pages about GPU troubleshooting:

Thanks Jacob!

You are welcome, Oscar.

I'm posting a new post. Regarding CPU vs GPU comparison in so far an anti-aliasing (jagged effect) is concerned, if you're interested.

I found that I did not plug my monitor into my graphics card.

Instead, I used a HDMI cable to  plug my monitor into the back of my PC.

3 hours or research, and not once did I have it put to me to check I did the above. I didn't know I had to use the graphics card ports instead of the other ports on the back on my new PC.

Hope you've a good day.
