CTF Project Printing Shirts

The CTF team has decided to print team shirts. You can find out exactly how it was done in this article.

Printing

First, team members picked a design. This was inspired by numerous capture the flag tools. Of course, pizza can’t be missing at a CTF event. ;)

The shirts were made by 3 members in the Siebdruck-room, at the HdM, under the supervision of a staff member.
The shirts were placed on a spider and the sieve was used to apply the design to the shirts.

To put the design on the shirt, ink must be applied to the sieve. Now the color must be pulled over the sieve with constant pressure and a certain inclination.
This must be repeated one to three times, then the sieve can be removed from the shirt. The finished shirt must now be put into the dryer.

After the drying process, the shirt was printed on the back. Here, only the logo of the ICS and the HdM was applied, as well as a QR code to the CTF page. This had to go back into the dryer.
The drying process only dries the wet paint. The paint is still washable with water until now. To get the color waterproof, so that it does not disappear when washing the shirt, it must be ironed. Only through this process, the color is no longer water soluble.
