Print Specifications: The Advantage of Adequate Files
After you finished the design of your label, you can dub your file press-ready. Save your document as a PDF-file. Underneath you can find a description of how to create a PDF-file (per program).
CMYK colours are the basic colours for printing (C: Cyan, M: Magenta, Y: Yellow, K: Black). By mixing these colours, you can create almost all colours. RGB colours are light colours, that you commonly use on your monitor (R: Red, G: Green, B: Blue). You will notice major differences on your monitor because RGB colours are brighter than CMYK colours. When you convert an image with RGB to CMYK, the colours will change. You can use Photoshop to adjust the image to your wants and needs.
The Pantone Matching System (PMS) is a standard colour system for printing. PMS colours are colours that are mixed manually. When you choose a particular colour, only that colour will be used when printing. The Full-Colour press technique works with opposite values, whereas one makes use of a grid. PMS is comparable to RAL colours, which works according to the same principles. Differences in your layout may occur when choosing PMS colours for layouts and CMYK for printing. It’s very important to take this into account.
How do I convert my file to CMYK?
When you place an order on Zolemba, you will probably get the question if you want to place white ink on your label. What does that mean? Below we explain what white ink is, what it is used for and how this is added to your design.
What is white ink?
White ink is a white layer underneath the colour print of your label. You can choose for white ink to maintain the colour fasting on your label.
How does this work?
At first, white ink is printed on the label. After this, the colour gets printed, overlapping the white ink. The white surface will make sure that colours appear as more ‘fast’. The option to add white ink to your design is fully up to you. Depending on your label, you can decide if you want to add white ink or not.
To which materials are white ink applicable?
White ink can be printed on the following materials;
- Paper silver/gold
- Paper fluor orange/yellow
- PP silver
- PET clear
If you do not choose to place white ink on your silver or gold label, a great colour type will come forward, ‘metallic’.
If you do not choose to place white ink on your clear (Transparent) label, the colours will automatically become transparent too. White (without white ink) won’t be able to be printed.
How do I add white ink to my design?
1. You can add white ink to your design when you want to make sure that your labels get printed on a white surface. Follow the following steps in Illustrator:
Place an additional element with white ink underneath. Before this, you can copy, for example, the text.
2. The copied element will be shown in white ink: - create a colour swatch
•• Create a colour swatch and name this swatch ‘white_ink’, choose for colour type ‘spot colour’ and the colour mode CMYK (like anything else in your file). Set the values to 0%. Give the copied element this colour.
Everything that needs to be printed, needs to have the filling colour ‘white_ink’. This is also applicable to the white text. Whatever white element won’t be printed on coloured or transparent labels unless it includes white ink.
Imagine your label is of PET material and you would like to have a blue element with light blue text. You want to colours to really come forward. In this case, you first have to place an element with white ink, above the blue element, above the text in white ink and above that the blue text. In total, you will have 4 printing layers. When you order the labels online, choose ‘full colour + white’ in the label configurator. Do you have any questions about adding white ink to your design?

Make sure that there are no important texts or images in between the 2 mm expiration and edge of the label. In that way, we can make sure that no important objects are excluded.
The minimum letter height is 1.32 mm. Texts with smaller letter heights will not be legible on your label. This is in line with the corps height of 5pt.
There should be no safety on your file when delivering, otherwise, we won’t be able to process the file. When you save your PDF file with the PDF/X-1a:2001 profile, no obstacle should occur.
