What is a Dieline?

HOW TO CREATE ONE,
EVEN WITH A CUSTOM SHAPE

A dieline is a critical element in the finished label’s design file. It states the exact size and shape of your final label when printed. It can be any shape or size for a custom label.

In its simplest form, a dieline is a shape with at least a 0.5 pt stroke in a spot color that is not used anywhere else in your file and on its own layer.

Even the most straightforward label shape (rectangle, square, etc.) needs a dieline to be produced correctly.

Therefore, before creating your label art, you must ensure your document, including a dieline, is set up correctly.

For example, if the label’s finished (or trim) size is 4” x 4”, this is how to set up your file.

For this example, we are using Adobe Illustrator, the preferred program.

  1. Create a new Document.

  2. Set Artboard Width to 4 in and Height to 4 in.

  3. Set Bleed to .125 in. on all sides, Top, Bottom, Left, and Right.

  4. Under Advanced Options, set Color Mode to CMYK Color – this is VERY important.
      • Any other color profile will result in unexpected color shifts when converted to CMYK and printed.

Creating the Dieline

Now that you have the file size (artboard) and bleed set up. You can create the dieline. There are a few steps you need to do before creating the shape and using the same 4” x 4” trim size (also the same size as your artboard as assigned above).

  1. Create a new Layer.
  1. Name your new layer Dieline.
    • It should always be the top layer, especially if you have an unusual shape.
    • There shouldn’t be any other art or text on this layer.
  1. Create a new spot color named Dieline:
    Cyan – 0
    Magenta – 100
    Yellow – 100
    Black – 0
  1. Using the Rectangle Tool, create a 4” x 4” square.

  2. In the Transform Panel, make sure your new 4” x 4” square fits exactly centered in the artboard.

  3. In the Transform Panel, you can set your corner radius measurement. This is another crucial step.
    • For example, you may want your corner radius to be .125”, while another customer may need their radius to be .25”. We may have a 4” x 4” die on hand. A new die will be ordered if your radius needs to be .125.”
  1. With your new dieline shape still selected.
      • In the Color Panel
        • Fill is specified to None
        • Stroke is specified to Dieline
          • Again, make sure you don’t use this color in the rest of your file.
  1. Lock the Dieline Layer.
    • Locking the layer avoids creating art on the wrong layer when you start designing.
    • Again, you don’t want any other art on this layer.

This is what your new file should look like with a dieline and bleed when your guides are showing.

Now you can begin the design process.

  • Keep any text, important content, or anything not intended to bleed .125” away from the final trim size.

Creating a custom shaped dieline

If your label needs to be die cut in a custom shape, the process is similar, with a few exceptions.

For this example, we are using Adobe Illustrator, the preferred program.

  1. Create a new Document.

  2. Set Artboard Width to 8.5 in and Height to 11 in., unless you know the size of your custom shape. If you know the size, set it to that. We will change the size of the artboard later.

  3. Set Bleed to .125 in. on all sides, Top, Bottom, Left, and Right.

  4. Under Advanced Options, set Color Mode to CMYK Color – this is VERY important.
      • Any other color profile will result in unexpected color shifts when converted to CMYK and printed.

The custom shape Dieline

Now that you have a new document created, you will need to create your shape or dieline. The size and shape are up to you and your needs for the label.

In this example, we will use this shape that we created.

  1. Create a new Layer.
  1. Name your new layer Dieline.
    • It should always be the top layer, especially if you have an unusual shape.
    • There shouldn’t be any other art or text on this layer.
  1. Create a new spot color named Dieline:
    Cyan – 0
    Magenta – 100
    Yellow – 100
    Black – 0
  1. Using your Pen Tool, create your dieline shape.
  1. With your new dieline shape still selected.
      • In the Color Panel
        • Fill is specified to None
        • Stroke is specified to Dieline
          • Again, make sure you don’t use this color in the rest of your file.
  1. Lock the Dieline Layer.
    • Locking the layer avoids creating art on the wrong layer when you start designing.
    • Again, you don’t want any other art on this layer.

Once your dieline is created, you will need to know the shape or finished dieline size.

  1. Selecting the whole shape – the dieline size is 2.1 in x 3.5 in.
  1. Change the artboard to reflect that size.
    • Open the Artboard Options dialog box.
    • Double-click the Artboard tool.
    • Change the size of the artboard to 2.1 in x 3.5 in.
  1. In the Transform Panel, make sure your dieline shape fits exactly centered in the artboard.

This is what your new file should look like with a dieline and bleed when your guides are showing.

Now you can begin the design process.

  • Keep any text, important content, or anything not intended to bleed .125” away from the final trim size.
