decal questions: tracing Jpeg to Vector

I'm interested to design my own decals, I do have the graphic in Jpeg file that I want to trace in vectors, so I can print it scale it on decal sheet later on. :grinyes:
I did know and use photoshop alot, and I do know little bit about adobe illustrator..:screwy: I use the quick trace option that illustrator have, but it seems I still need to learn much more tricks from the experts here. :grinyes:
with all due my respect, can someone here helps me to how to trace jpeg in illustrator and accurately scale the proportion. I did read couple tutorial but nothing came close what I'm looking for...

thank you very much

I have used Photoshop and Illustrator for years now and I can tell you that there´s no way to obtain a exact vector image from a jpeg using Illustrators tracing commands.

The only way is to paste the jpeg image in a layer and using it as a guide to hand trace the image in a new layer.

There are other programs that "vectorize" pixel images, but you will get nothing close enough to your original.

I do the same as sam01contact (http://www.automotiveforums.com/vbulletin/member.php?u=173625), but sometimes Corel Trace can help or even Adobe Streamline

I agree with those guys. There is no 'automatic' way to do it, (although the 'live trace' in CS2 is pretty close) you just have to go in with the pen tool and make it using the jpg as a guide. Then measure your model and scale the image to the size you need it.

It takes practice to get it nice and clean. Luckily, because of my profession, I've had to use Illustrator nearly every day for the past 12 years.. but I can understand how Illustrator can be intimidating at first since it's a pretty complicated program.

I've the CS but the new illustrator have some new updated autotracing functions (a kinda strelmline inside?).

BTW my job would be really a bit easy if I could find an half decent autotracing function. Streamline is good, but for an "artistic" approach, not for stright tech themes like what we often have on decals.

BTW(2 ;) ) this is part of the fun of do decals at home :D

Currently I use Photoshop CS, CS2 is too hardcore for my computer.

This works with PS 7.0 also.

The best way for decal purposes...
1) Open your .jpg file and resize it, make it big. Experiment a little.
2) Image > Image Size... bump the resolution to say 300pixels.
3) Depending on how many colors there are, create several new layers.
4) Work on the color most "out" first. In your new layer use the polygonal lasso tool to trace the design.
Tips when using Lasso tools:
- Zoom it up, close.
- If you ever want to move the image, hold the space bar and click.
- Accidentally clicked too much? Use the Delete key to rid those extra points.
- Want to start over? Press the Escape key.

Really all working with PS is all trial and error. Practice, mess around a little. Get used to the work space, and understand what each tool and feature has to offer you. It's fun, if you enjoy manipulating images.

Here are a few "vectors" of mine done on PS CS:

1987 Toyota Corolla

And just for kicks, my car.... lowered, etc.

Those designs can pretty much be used as a decal for a model. It's all the same. Keep in mind only certain printers print in white.

I actually found a "auto tracing" feature on a Gerber Omega. It's a program used on sticker cutting machines which separates color layers pretty well. Don't bother looking for a download, there is a USB plugin "key" to run the program. Really a sophisticated program if you ever have the opportunity to use it.

Good luck!

thanks for the replies guys!
Honoturtle that is an awesome artwork you've got!!!
was that done by using Ph-shop software?

Photoshop CS (8.0)
Thinking about buying the CS2 (9.0) upgrade since I just got a new computer, much faster than my old one.

I might/ probably will not use the new features, so I've been back and forward about it. Maybe just for kicks! :icon16:

Hi guys,

I know this is asking a lot, but is anyone here able to help me trace this into vector format? I'm printing a decal for a conversion that'll be starting on soon, and I have no access to illustrator.
