There are different methods of screen printing, but they all involve the same basic technique.
The form of printing we’ll talk about below uses a special light-reactive emulsion to create a custom stencil; this tends to be the most popular type of commercial printing, as it can be used to make intricate stencils.
So what do you need to build up a tech pack, I would say you can narrow down to 5items.
It includes drawings, measurements, fabric, trims, and everything that a supplier would need to know to make your idea into a product.
The 1st thing is a drawing because you’re not an expert of illustrator.
You need a hand drawing with a clear description and requirement.
What you need to do is let your supplier know what your design is.
The 2nd thing is the measurements. Remember, there isn’t a standard size.
You need to figure out your own custom size.
At least you need to give the main sizes, such as length, chest, waist, sleeves, etc.
The 3rd thing is the fabric requirement. So you need to let your supplier clear about type of fabric like single jersey, thickness like 200 gms, color, and other requirements.
If you don’t know much about fabric, l have a suggestion for you.
Send a reference sample and ask your supplier to source the same or similar fabric.
The 4th thing is the trims, like zipper, buttons, neck tags, swing tags, etc.
Also, if you are not sure, just show a picture to let them know what you want.
The 5th thing is pining or embroidery requests.
Well you know, it is really popular to have printing or embroidery on clothing. And before you do that, you need to prepare a high resolution printing or embroidery file.
Tell your supplier how big the print should be and where the position is, like 5cm below the neck.
Why do you need a tech pack?
Because you need to make supplier know more about your designs.
