How to convert your art to vector.

In order to provide you with the best quality prints, we require custom label artwork using white ink to be provided in a vector file. Here are some quick steps to converting your artwork files to the proper format.

What is a white underlay?

A white underlay (or underprint) refers to the process of printing an initial layer of white before applying the artwork print.

How does it work?

Your purchase of clear custom roll labels include a white underlay. This allows your label design to be completely visible and opaque on the clear material. In order to apply the underprint to your labels, we require a vectorized version of your artwork.

What is a vector?

A vectorized file is an image that uses mathematical formulas to create shapes. Vector files are typically used when an image needs to be scaled without the loss of quality.

How to Convert Your Artwork and Prep for White Underprinting

Adobe Illustrator

  1. What you want printed in white must be in a separate layer. Apply a "spot color" color swatch and name it "White."
  2. Ensure that the color mode of the document has been set to CMYK. File -> Document Color Mode -> CMYK Color.
  3. Apply an attribute to each layer. Go to Window -> Attribute -> Overprint fill or Overprint stroke (if your design has strokes).
  4. You should make the white design under your CMYK design slightly smaller. About -.2pt. This will ensure your artwork is seen clearly when placed on a transparent background.
  5. When you're ready to save, go to File -> Save As. Save the file as a PDF.
  6. Select PDF/X-4:2010 and save.

Adobe Photoshop

  1. Convert your image to CMYK color mode. You can find this option under Image -> Mode -> CMYK color.
  2. Choose the areas of your artwork that would need white ink printing.
  3. Go to Window -> Channels to create a new channel. Fill the areas you selected with blank. You can do this by going to Edit -> Fill
  4. Double click on the newly created channel. Indicate that it's a spot color. You can name it as "White." CMYK colors will be added on top of this channel.
  5. When you're ready to save, go to File -> Save as. Save the file as a PDF.
  6. In the next window, make sure PDF/X-4:2010 is selected.
