Artwork Considerations for Screen Printers

Account for various artwork considerations when creating designs

You will want to account for various artwork considerations when creating screen-printed designs. Due to the nature of screen printing and all the different variables, such as screen exposure, T-shirt fibers, and curing, graphic design for screen printing varies from traditional design for web or paper. While many designers work in Adobe Illustrator, screen printers prefer CorelDraw for design, color separations, and film output.

When working in CorelDraw, you should set up your workspace desktop inside the program to facilitate efficiency. One way to do this is by creating a floating toolbar. Put your most used tools on the toolbar, so you do not have to keep going into the menu at the top to select them. Screen print designers typically use the alignment, outline, fill, and find & replace features the most. Having these as quick buttons on your desktop will speed up art production.

Keep any outlines in mind as you manipulate your artwork. For example, a left-chest logo with a six-point outline disappears when you scale the image for a full back. To work around this, change your outline to an object. Then, the outline will scale with your image. You will be able to go from a left chest, to a center chest, front, full back, etc. without having to worry about fixing any image outlines.

When designing, be mindful of your line thickness. Most people view (and approve) the image on their monitor or sheet of paper. While the essence of the image stays the same, the nature of a T-shirt differs. A shirt is more absorbent than paper, and the screen-printing process drives the ink into the garment itself. This can affect the thickness and boldness of your lines. You can counteract this either through advanced stencil-making techniques and sophisticated printing methods (high mesh counts, modified inks, proper off-contact) or by changing your artwork.

Another artwork consideration when designing on a computer is to keep in mind the use of negative space. Most computer monitor backgrounds are white. However, the most popular T-shirt color is black. Take this difference into account during the design phase, as it can change the way you design. For example, car tires on a black shirt typically need a white outline. An alternative is to create a background for the art file in whatever color your shirt will be. This will force you, or your artist, to design with the shirt color in mind.

Finally, while halftones go from 0-100% on paper, T-shirt designers should be somewhere in the 40-75% range. More than that amount and your image might look like a full, spot color because of the differences between T-shirt absorption versus paper discussed earlier. If you go less than 40%, you might have issues holding the dots on your screen unless you are using very high mesh counts and properly tensioned screens.

While these basic considerations are simply meant to serve as guidelines when designing for screen printing, they will help any beginner screen printer to produce great looking artwork that is ready to be printed on T-shirts.
