In this tutorial I'd like to
share with you how to use Adobe Illustrator to complete a design for the
particular purpose of being printed on a piece of clothing. I'll be sharing
tips and tricks I've learned during my time designing for apparel and using
simple techniques in Illustrator to achieve this - nothing complicated!
Draw Your Design
Begin by roughly sketching out
what you want to include in your design, it's okay to add details in at this
stage, the more you have finalized the better! It just means less time
deliberating what to include and what not to later in Illustrator. Try not to
spend too much time on it however, especially if you have a deadline to keep! I
personally use either pencil or fine liner pen - your preference really! When
sketching out ideas it is also important to keep in mind that this is for a t-shirt,
don't get too complicated. Keep asking yourself "would I wear this?".
2. Scan Your Illustration
Having completed your sketch,
we're now going to scan it into the computer. It's important to always scan in
at a high quality - I would usually recommend choosing the Black & White
setting on your scanner (assuming it has this option, some scanners are
different) along with a resolution of around 600 dpi, but no less than 300 dpi.
These settings will ensure the quality of your scan.
3. Vector Your T-Shirt Design
With scanning out of the way, I'm
going to create a new file in Illustrator (File > New) and we're going to
use the settings shown in the picture. The most important setting here is the
CMYK color setting. CMYK ensures that you can take your design to print later
with no problems.
We are now going to place our
scan onto the canvas by going to File > Place. Position it to your liking on
the canvas.
Create New Layer above your scan
layer called "lines" by using the button highlighted in the image.
Then Lock the scan layer, making sure you don't move it around or, in later
steps accidentally draw shapes on your scan rather than your "lines"
layer.
Before we start drawing over our
scan it's important to set up your Calligraphic Brush Options first. For my
illustration I used these brush settings shown in the picture by selecting the
Paintbrush Tool (B). It helps a great deal here if you own a graphics tablet -
it's something that in this line of work is a very necessary and a worthwhile
investment. If you do own a tablet the pressure setting will help a great deal
when you are drawing lines and will give you a lot more control. It's good to
play around with the variation setting to get one that you like and feel
comfortable with.
It's also important to choose
your colors early on - keeping in mind printing costs. For the most popular
method, screen printing, printing setup and the printing itself gets
increasingly more expensive the more colors you use. It's therefore good to
keep it a relatively low number of colors I chose 5 colors, which is probably
the maximum you would want to use, unless directed otherwise by a brief. If you
need help with choosing color schemes, I would recommend using Adobe Kuler for
help.
It's now time to go over your
lines using the Paintbrush Tool (B) with the settings we set earlier. This is
where the pressure sensitivity of your graphics tablet will help. You also
don't have to stick to your sketch lines, it's good if you have new ideas to
implement them. If you look at my sketch next to my finished lines they are not
the same.
It's also good to Group your
lines together according to area by Right-click > Group. For instance, if
you are drawing character-type design like myself I would group all the lines
that make up the head area - this makes re-positioning areas quick and easy
should you need to change this later on.
Another good tip is to change
your Stroke Weight for different areas to add some detail. For instance
changing to 0.25px on the top menu bar to add in little details.
The next step is to Create New
Layer below your "lines" layer called "color". You also
should Lock your "lines" layer like you did with your
"scan" layer earlier to prevent accidental editing.
The next step is simply to color
your lines! Use a combination of the Paintbrush Tool (B) to color in like you
would on paper(fun!) and you can use the Pen Tool (P) for larger areas and to
be more precise! For example, I used the Pen Tool to cover the area of the
t-shirt by creating anchor points all around the outlines as it is a lot faster
than coloring in with the brush. You can also add highlights using the other
colors you are using. This, similar to changing your Stroke Weight when you
were drawing your lines, will help add depth to your illustration.
Shown in the pictures is the
separated colors I used as well as the line work to give you an idea of how to
color You can tell which areas have been colored-in using the Paintbrush Tool
(B) and the larger areas that have been colored using the Pen Tool (P).
Prepare Your File for Printing
Once you are done with the
coloring and are happy with your illustration, you should highlight the entire
illustration, every layer except the "scan layer". Then go to Object
> Expand Appearance. This expands all your brush strokes into filled shapes
and will allow you to re-size the illustration to any size without losing quality.
When resizing strokes in illustrator it can result in the strokes being either
too thick or thin, therefore this is a key step.
When everything is finished the
natural next step is to of course go to print. It's very important however to
first check all your colors are correct and that you haven't accidentally used
more than the amount you decided on at the beginning - this can cause extra
unneeded printing costs.

If the design is for yourself or
for a client as part of a commission, it's always good to mock-up the design
onto either a photo of a t-shirt, or a t-shirt vector template. You can find
these all over the Internet available for free. This step is particularly
important if the design is for a client, it always helps to be as professional
as possible!
When sending the file to the
printer, most will be okay with an AI file, some will prefer EPS. It's very
important to always specify the exact proportions of the design as it would
appear on a t-shirt and the positioning of it - you may feel that is obvious
but the printer won't. It's also good to include the Pantone codes for each of
the colors you used to make sure the printing is exact and the same as the
design. If you want to or have the time you can select all the shapes of each
color by selecting one shape and going to Select > Same > Fill Color and
separate them all onto separate layers. This can make the process easier for
the printer although is not always required.
Hey, That's One Awesome T-Shirt!
I hope this helped your process -
whether you are thinking of starting up your own clothing line, or you're an
illustrator and thinking of offering this service to clients. Bear in mind in
the clothing industry, the design is arguably the most important thing, and
therefore it is important to get it perfect!
