How to Put a Decal on a Cup

For almost has as long as I've been blogging on Silhouette tutorials, I've been getting asked the question: "How do you put vinyl on tumblers and cups straight?"

Since I know you're all dying to know - I am going to share a few tips on what has worked for me.  Plus I'm going to give you all a really handy cut file to help you get that vinyl straight no matter where it's being placed on a tumbler.
So the first thing we need to talk about is why vinyl doesn't go on straight when applied to some tumblers.   You can blame the conical shape - being wider at the top than the bottom - for your troubles.

When trying to apply a straight line of text to a conical shape it will naturally curve up as shown in the bottom example below.  You can see that if the design is created in a perfectly straight line, when applied the ends will be slightly higher or lower than the middle.   Bad. Very bad.

To counter this when designing, you need to intentionally give the text a slight curve (top example above) so that when it's applied the ends will curve up and naturally even out with the top of the curve.  Please note that shapes can't be morphed this way in Silhouette Studio - only text.

Now, when I say you need to give the text a slight curve I mean very slight...take a look at these designs. They look identical at first glance.

But they're actually not.   Each line in the gold design has a slight curve to it, while the red design is perfectly straight and aligned.  It's more obvious when I turn on the grid lines.

Look at the "OO" in Good, for example. You can see the gold "OO" is not quite sitting on the line whereas the red "OO" is since it hasn't been forced to curve.  The G is also slightly tilted to the left and the D to the right...that's due to the curve.

The curvature is minimal, but it's enough to negate the conical shape of the surface where the vinyl will be applied.

How to Curve Designs and Text for Tumblers (and Other Conical Shapes)

Now for how to get that curve.

You can use the Conical Warp tool if you have Designer Edition Plus or Business Edition.  To use the conical warp tool select the design or text then open the Warp panel and select the Conical Warp tab.  Enter the dimensions of the tumbler and click apply.

The design will be given a slight warp.

Text to Path for Curving Text

If you do not have access to the Conical Warp tool you can curve text, but not designs using text to path.

For Life is Good Today design I created the three line text design in three separate text boxes.  You don't have to, but I think it's a good idea to size the text so it fits on the tumbler before taking the next step.   In this case, my design is about 3.5 inches in height.

After I sized, I opened this handy dandy tumbler template I have in my library - which just so happens to fit perfectly into a 16 oz double walled paper lined tumbler from My Vinyl Direct - and I put each line onto the curved path.  You can download the tumbler template too.  If you do, just remember not to resize it at all or you'll change the size of the curve.

To put text on a path double click the design until you get the green box around it. Then grab the little directional arrow in the bottom left corner of the text box and drag the text box until it kind of snaps onto the path which in this case is the tumbler template.

The most important and final step of this process is to right click > convert to path. This basically freezes the text in the shape of the path and allows you to move it off the path while it still keeps its shape.

I repeated this same process with all three lines of the text.  Then I grouped the three lines together. The finished result is the gold design you saw in the above images.

Now you can simply cut the design on vinyl. For anything that is going to be washed or handled a lot I cut on Oracal 651/permanent vinyl.  In this case I cut on glitter gold adhesive vinyl.

As I said, I was working with a double walled screw-together tumbler from My Vinyl Direct. The insert is removable and total customizable.  I unscrewed the two walls of the cup while I applied the vinyl and you'll see why in a minute.

After the vinyl was cut and weeded I cut off a piece of clear transfer tape. I use clear because I want to be able to see through the transfer tape.

Before I applied the design onto the tumbler, I did two things:

1. I filled the tumbler with a small amount of water. This gives me an even baseline.  So now I can match the bottom of my design along the waterline and know that it's perfectly straight - without even measuring (gasp).
2. Cut small slices up from the bottom of the transfer tape toward the design (indicated by red lines in the image to the left). This allows me to slightly manipulate the shape of my design even more if necessary. Just be careful not to cut into the actual vinyl design.

And now I'm ready to apply the vinyl to the tumbler...I placed the bottom line right along the water line (this is why I removed the inner wall of the cup, I needed a really clear view of the water line)- this can best seen in the "day" area.  Once the bottom is in place I applied the rest of the vinyl design from the middle out toward the edges.

The slight curve in the vinyl, the water line, and the snips in the transfer tape are all essential to helping put the vinyl on the cup straight.

Burnish the vinyl onto the tumbler and then peel away the transfer tape.

You can replace that insert if you have it, leave it out, or customize it however you'd like.  Since you already have the template in Studio, you can even fill it with a pattern in Silhouette Studio and then print and cut it and it will fit perfectly into your tumbler - this way you can change it out from time to time to match the holiday, season or your mood.
