Rendering with jagged edges

Postby jgeck90 » Thu Sep 13, 2012 9:57 am

Hello, i am trying to render with inkscape and all i get i jagged edges on the text. I have a customer asking for these decals and i cant seem to figure out why i am unable to render this so i can cut it and send it to him.
Jeff.
Any help would be appreciated.
Thanks

Welcome Jeff!

I'm not sure if I'm seeing the problem that you need to solve. Are you using Trace Bitmap on the logo on the right, with the result on the left? Or otherwise, can you point out the jagged areas?

Trace Bitmap is not meant to accurately reproduce photos or other images. You can probably adjust some of the trace settings, and get a little better trace. And you can probably get pretty close to the original, in this case. But still there will probably be a few areas where you need to tweak it (with Node tool).

Some people have had some luck by adjusting the contrast, sharpness, and color components in a raster editor, in order to get a better trace in Inkscape. But I couldn't tell you exactly how to proceed with that.

Having said all that though, I'm not positive you're using Trace Bitmap.

I'd almost think it might be better to redraw the whole logo from scratch, except that you'd need to have access to the original fonts. And the font on the largest text looks pretty unique.

Thanks for the Welcome! And the reply.
If you look closely at the text where it says "Imagination is power" you can tell that its not the same as the original copy. How can i get an exact copy of that logo into a vector so i can cut it with my cutter?

If you look closely, almost nothing is exactly the same as the original. If you have a good original, you should be able to get a fairly accurate trace. I'm not as talented with Trace Bitmap as some other members. But I'll grab your original, and try to find the right settings for the best possible trace. Or maybe said others will give it a try.

The parts that appear in white, as I look at your sample, are they white, or are they transparent? If you put the decal on something red, would the currently white areas look red, or white? I'm guessing white, since the page border can't be seen through the white area.

Also, should the finished product have the "sample sample" watermark? Did you add that to protect copyrights while posted in the forum? Or is it not a watermark at all?

Is that the full size of the finished decal? It would be better if we had the full size to work with (although not strictly required). Actually, it might be better if we had the original file, rather than taking the one you posted here. The more clear the original, the better the trace. Would you be able to attach the original?

I guess you don't have access to the original fonts? If you did, it wouldn't be very hard to draw it as vector from scratch. Then it would almost literally be perfect! I'm so tempted to try it..... :)

Well anyway, let us know :D

Thanks a lot for the reply.
I'll attach the original copy to this message. Where it says sample is not needed. The parts that you see in white are white and will be cut out. The parts in black will be the actual decal. I have a few designs that are a fairly low quality and i don't know the original font. I would actually be willing to cough up a few bucks to anyone who can help me get these sent back to me ready to cut in signcut or sign blazer format.
Thanks much.
Jeff.

Edit: I've opened the org files in photoshop and saved them from eps to jpeg so i could upload them.

Hhhm...the originals are black on kind of a teal color. But I guess that gets cut out anyway. If I can figure out a good configuration of settings, I'll just give them to you, and you can do the rest....unless it gets more complicated that I expect at the moment. After I finish spam patrol today, I'll see what I can do.

Of course anyone would be welcome to try, as well, I'm sure. Especially if tweaking in a raster editor could help with the clarity. I probably don't know how to approach that.

Anyway, I should be able to post results later tonight :D

You are correct on the teal color. I think that happened when i uploaded them to photobucket because my org .eps files are completely black and white. I can email the original copies if you give me your email address.
Thanks so much.
Jeff.

Hi Jeff,
The teal color itself probably shouldn't cause a problem since you said it will be cut away. But what I need is the original files, rather than the image hosted on a website. For some reason, photobucket has changed the colors, so that black is sort of brownish gray, white is teal, and there appears to be an orange line between the 2 colors. That's really throwing off the scan. The more contrast, the better, and for whatever reason, photobucket has practically removed all the contrast.

You could upload the files directly into the forum, or to a file sharing site, and post the link to download them. In case you don't know how, instructions can be found here: viewtopic.php?f=6&t=11753. I actually don't have the proper software to be able to open EPS files. But JPGs should be fine, as long as they are black and white, and sharp and clear.

I have tried with the teal/orange/gray images, but results are poor, and even worse than your original attempt. I'll try again tomorrow night, or as soon as I get the files :D

They're very small images. I can't imagine they're challenging the file size limit for attached files. Oh wait....looking at your first message, I see that at least that one image is close to the A4 page size. Even at that size though, it shouldn't be too large to attach. I'm sorry to be so picky, but the full size will achieve a MUCH better trace. I'd rather not share my email address, unless there's no other way. If you can zip together the 4 full size images, you can attach the zipped file.

Hi Jeff,
The 2nd one is still gray/teal. But for the others, is that the best quality that you have? I don't know if you can notice it, but they're not very sharp. I saw someone do a technique where they took the image into a raster editor and blurred it. Then by adjusting the Trace Bitmap settings they ended up with sharp clear edges. But I'm not sure if I have the right skills for that.

When you tried with Trace Bitmap, were you tracing the original EPS files? I think the problem is that converting to JPG is reducing the quality. At first I thought I could do better, by tweaking the trace settings. But now that I see the full size, in b/w, I'm not sure. I'll see what I can do. But I probably can't improve on your attempt.

Ok, well this is about the best I could do. Comparing to your effort, I see some things are improved, but other areas are worse. I think it might be time to have them redrawn....unless someone here can use the original EPS files. If the EPS are a better quality, maybe that would work. But if they're not better quality, it won't help...unless someone can fix them using a raster editor, before tracing in Inkscape. Unfortunately, I don't have the proper software to use the EPS files.

Note that this file only contains the same image that you showed in your screenshot. I did that so you could compare. I don't see any reason to do the others, since they are no better quality....unless this one is good enough for you. If that's the case, I'll be glad to trace the other 3.

In your original screenshot, it looks like the image is...actually a little bigger than the A4 doc size in landscape orientation (1166 x 755 px). The last ones you posted are only 448 x 326 px. If I could use the full size, it might make for a better result. Although considering the quality, probably not much.

Why don't you just ask the company (looks like it's just one graphic designer guy) for the vectors? As far as I can see the graphic IS their major product, i.e. it's not just advertising, it's that large logo on their clothing that they're selling. Look here for the owner describing the concept of the company ... If you or your client have Dunemis' permission to sell products with that logo, or perhaps manufacture items for them, then I'm sure they'll want to provide you with clean vectors. Of course if you don't have their permission then this is just about the clearest example of copyright violation I can imagine, and you'll have to make do with scans etc.
Not trying to criticize! Just suggesting an alternative!
Your mind is what you think it is.

Oh my! Yes, I agree, and you'll have to make do with your own scans. I won't be a party to a copyright infringement.

Thanks druban. As tough as I am on spam, I guess I need more lessons on recognizing potentially copyrighted content. I was wondering why that one image says "Imagination is pow" :mrgreen:

Very interesting that you found information on this logo.
I got a email from a guy name "Nicho" So i would imagine that the guy in the video is the same person. From the email it sounded like he was busy and just wanted some quick decals for his company. It's the owner of the company who i am dealing and he sounds very busy.

I will have to check into it more.

I totally understand why you guys wont help anymore.

On another note, what file type should i ask from him?
What he sent me wasn't a very good quality to begin with.

Maybe i will have to just print them out and re-draw them or completely re-design them in inkscape?

From his website, he appears to be well-versed in what printers and websites require. I find it doubtful that he would provide such low qualilty images, even if he was in a hurry. Plus, it looks like a "sticker pack" is one of his products. Maybe you could buy those?

i cant even believe that you would think that i am trying to steal this logo and make them.

I got a email back from him this morning and he said that what he sent me was the original vector files and they are .eps
What file type should i ask for? I can't cut a .eps file without vectorizing it.

They are pretty big almost A4 size and good quality but they render bad when i vectorize them.
Thanks.

Here's why I think that. This guy, Nicoh, owns these graphics which you are trying to reproduce. He's either the original artist, or has paid for the development of the graphics, which means that he owns the copyrights. He presents this clothing design business which he was trying to start as if it were his life's work. If he wanted to have decals of his designs (which are meant to be on clothing, not decals) he A) would provide you with the proper files to do the work; B) would not have provided an incorrect graphic ("imagination is pow"); and most importantly C) would hire someone to do it who already knows how to do the work. ;)

lol you are awesome. I have no reason to reproduce them or want to reproduce them illegally. If you go to his web site you can clearly see that it's not even finished and that video was posted back in 2011.
I figured it out and cut them today and sent him some free ones as samples.

Feel free to go ahead and delete me from the forum because this is complete Bull Shit that i am being told that i am stealing these designs. He obviously knows nothing about vinyl cutting and he is "human" and allowed to make mistakes by sending the wrong file type.

So you think it's ok to take his images, because his website isn't finished, or because his effort to start a new business was not successful, or because the video is 1 year old? You think no one will notice that you took them. What a classy guy!

You haven't broken any of the forum rules, so there's no reason to ban you. Or even to warn you. (Although if I were running a forum like this, the rules would be different!) We're here to help people learn how to use Inkscape. Sometimes we will do work for people, if it's a fairly simple task. Since I've used Inkscape's Trace Bitmap a lot, I know how frustrating it is for a new user. I thought I might know some tricks, and it would be a simple matter for me to do 4 traces for you. In the end, the images you provided are too small, and too poor quality to get a good trace. The file I posted, and later removed, was not good enough use anyway. I just removed it to make a point.

And the point is, that it's my choice whether I will help someone or not. I know how I would feel, if someone used my work without permission. So if I learn that there might be some question of ownership, it's my choice not to help. Other members here may feel differently. And if they do, maybe they will offer to help. But since it sounds like you've solved the problem, I guess there's no need.
