Screen Printing

This classic printing technique uses stencils to mark out a design, which is transferred onto the garment by moving a blade or squeegee across a mesh screen. One color is printed for each screen, so several screens can be used for multicolored designs.


This technique creates a high-quality, raised design by stitching the design into a garment using a special embroidery machine.

Using the right print type gets the best out of your design

Choosing the right print type is vital when it comes to a product with a design you upload. As a rule of thumb, designs using just a single color tend to come out better with flex prints (smooth). Whereas, digital-direct printing is the better option for pixel graphics (.png, .jpg) displaying many colors. Please note that only up to 5 colors are possible to print for a single design. Some items such as mugs can only be printed by way of thermal sublimation.

How does it work?

First, choose the product that you desire and upload your design:

After you have selected your product and uploaded a design, you can proceed to choose the print method of your choice. The option to choose the print method can be found just above the color selection of the product:

You can select different print methods by clicking the arrow. Available print methods will show according to the design that was uploaded. If a print method is not available in the drop menu, it may not be compatible with the design that was uploaded.

Once the print type has been selected, please select your design color. If a design has a background, a color for the design print and background will need to be chosen separately. Please remember to choose a color that offers sufficient contrast for your design.

Keep in mind that color availability is dependent upon the print method selected.

After you have selected the product, print method and design color you are all set! Then, hit the “Next” button – done.

Colors may look different on the printed item than they appear on your computer monitor or phone screen.

This may be due to different reasons:

To print pixel designs, we need to render the color scheme from RGB to CMYK and make color corrections if necessary. This may lead to slight color variations. Every screen displays colors differently. A combination of brightness, contrast, and saturation can change color effects significantly. It is important to note, different color inks will show up differently on different color fabrics.

Dark colored designs printed on to dark colored material is difficult to see. In addition, light colored designs printed on to light colored material is also difficult to see. The best practice is to have a high contrast between the color ink and the color material chosen. This will avoid the design color from "blending in" with the material color.

When unpacking a product that was printed with Direct-to-garment (Digital Direct), you might sometimes notice a vinegary scent. Don't worry, this is absolutely normal.

It comes from the fixation agent (or pre-treatment) that is used to make sure the print will get into the fabric. Otherwise, the print wouldn't hold on to the product correctly.

To get rid of this scent, simply wash the product following our Care Instructions.
