Printing Inks

What is the difference between Four Colour Process and Spot Colours?

Spot Colour

Spot colours are pre-mixed inks that generally create brighter, more vibrant colours. Millvale implements the Pantone colour range of inks which is widely recognised as the industry standard. The vibrancy of spot colours cannot generally be achieved by CMYK; however, spot colours have some limitations. Spot colours can only produce shades (tints) of that particular colour and nothing more. When supplying artwork you would need to ensure that the correct Pantone colour had been assigned to the artwork and not CMYK.

Spot colour printing would typically be used for jobs which require no full colour imagery or where a colour must be a guaranteed match such as in a corporate logo or brand style guide. Creating artwork out of multiple spot colours may require more than one pass through the press, so it is worth considering origination costs when creating artwork.

Four Colour Process

Four colour process printing involves printing four colours on the sheet all at the same time to create your colours, these colours are: Cyan, Magenta, Yellow and Keyline (Black) – CMYK. Four printing plates will be required to generated the job. Each of the four ink units on the press would hold one of these primary colours. The job would be printed, in one pass, coming off completed at the other end of the press.

The advantages of printing in CMYK is you can produce a wide variety of colours; print text, photographs and logos all together in one pass using the CMYK process, thus reducing origination costs. Rationalising artwork across product ranges or printed materials by using CMYK can be a key tool in reducing marketing or packaging costs.

How do I give the measurements for my Carton?

Understanding carton measurements is as easy as 1-2-3.

Carton measurements always refer to the inner dimensions of the carton. This is done to ensure an optimum fit around your product. Simply measure the length, width, height (as shown in the diagram) of what you would like to pack and express the measurements in millimetres. Make sure to give the dimensions in this order:

  1. Length
  2. Width (Depth)
  3. Height
