And we're back to Screen Printing Art 101! If you watched the video about making color separations in Adobe Illustrator, you'll want to watch our latest video as well. Screen Printing Expert Colin Huggins walks you through the process of creating the white underbase in Illustrator.
Huggins uses a three color design in the tutorial. The design has big open areas as well as tiny, intricate designs. Having the varying level of detail will help demonstrate the best way to create the underbase, no matter what art you're working with.
Of course, there are always keyboard shortcuts that are super helpful to know when making designs. Here are a few you should keep in your back pocket:
Insider's Note: Having a large monitor is extremely helpful! You'll have more space in the program to play around while still having easy access to all your tools.
Printing the wrong design or placing the design incorrectly is a costly mistake. To avoid this issue, Colin suggests putting as much information about the order on the film. Details like the date, where on the garment the design will be printed, mesh counts, colors, etc. It makes it easier for the printer and helps keep the process moving smoothly.
When it comes to registration marks, it's up to you to decide what'll help you register perfectly and easily on press. Colin likes using 1 pt thickness for his registration marks because it helps him see when he's off quickly. Using 2 or 3 pt thickness makes it less obvious when registration is off.
Before making the white base, you need to clearly separate each color. With Colin's design, there are areas of it that need to be filled. Parts of the design overlap with other aspects, so those areas need to be merged in order for the white base to be made correctly. Here are the steps to follow to clearly define each color:
Time to make the underbase. Let's look at the steps Colin takes to achieve this goal:
As you see, Colin ran into a little issue. One aspect of the design did not apply to the white base. The program recognizes this area as an empty space; therefore, it noted the area as zero fill, zero stroke. That's actually a helpful hint for you. All you need to do is go to the menu on the left of your screen, select the color swatches that say Zero Fill and Zero Stroke. Go to Select, hover the cursor over Same, click Fill & Stroke. Select the layer and delete it.
When printing white underbases, printers do not want the white base to show on the print. To make sure that it doesn't happen, the white base needs to be slightly smaller than the design so that the colors can cover the edge of the white base. What you'll need to do is choke the white base. To choke the base, make the stroke not as thick as the strokes on the colors. If the strokes on the colors are one point, try 0.5 for the underbase.
