I don't have Adobe Illustrator, what should I do?

Unfortunately, due to the constraints of our accepted file formats, we can only accept either AI., PDF., EPS., and on rare occasions, PSD files.

In such circumstances where you do not have Adobe Illustrator, we can recommend looking at other vector-editing programs similar to Adobe Illustrator however, the same rule applies when it comes to our accepted file formats.

Alternatively, you may look at our artwork design services to help assist you with any design work you may require.

What is the recommended file size

Due to various reasons, we only accept file sizes up to 100mb. However, files larger than 100mb may be accepted by request only with your product specialists.

illustrator iconColor Profiles

How do I change my document to CMYK color mode?

To change your document color mode, navigate to your App menu: File > Document Color Mode > CMYK Color

Important: While your entire document color mode has been converted into CMYK Color, any image assets must still be converted into CMYK for added precautions

Important: While PakFactory will try it's best to match the gradient density of each color, PakFactory is not liable for any discrepancies in the final color output. We recommend when reviewing your CTP to ensure everything is to your expectation before submitting your final production order.

Can I print using RGB color mode?

The RGB color space is commonly used exclusively for digital displays and is not recommended to be ever used for printing.

Due to the nature of how printers process color information, CMYK or PMS colors are the only recommended color spaces for printing.

Learn more about the RGB color model and why it's not used for printing.

Why should I print in 100% K value?

When printing black elements of design such as text, using the CMYK color mode, the K (Black) ink in printers provides a more accurate color output.

Tip: Due to the variance of black when using the CMYK color space, we recommend to speak with our product specialists to specify the type of black you would like to use on your packaging. Here are different types of blacks:

Warm Rich Black
  • C 30
  • M 40
  • Y 50
  • K 100

What's the minimum font size?

The minimum font size for legibility varies depending on the product material and your chosen printing process. However, the safest recommended printable minimum size for fonts is generally at 8pt and reverse print at 10pt.

Keep in mind that some typefaces have thinner or lighter font weights, which may affect the print legibility.

  • Dark text on light background: 6pt
  • Light text on dark background: 8pt

If unsure, please consult with our product specialists to ensure your printed texts come out readable.

To ensure no mishaps during production, properly communicate with your product specialists as well.

How do I prepare files for additional printing options?

To properly communicate to our production team about any special options or printing (Pantone®, foil stamping, spot UV, etc.), additional file preparation is required to avoid production issues. Please follow these steps closely to prevent any production delays and errors:

  1. All other printing options should be indicated appropriately and separated into different layers.
  2. For clarity, they should also be placed on a duplicate artboard in black (100% K value).

  1. If your packaging requires interior printing, please indicate properly on separate artboards "Inside Print" and "Outside Print."
  2. The interior and exterior artwork should also be placed in separate layers and properly named.
