Colours can vary from screen to print (and vice versa)Unless you’re a professional graphic designer or similar, you might not be using the kind of high quality monitor suited for working with colour reproduction, or it hasn’t been calibrated. Maybe you have night mode turned on your monitor to combat the amount of blue light it emits, which can disrupt your circadian rhythm. Maybe your desk faces a floor to ceiling window, that turns into a floor to ceiling glare on a cloudy day. Maybe at a certain time of the afternoon, a strip of sunlight travels across your screen from a gap in the curtains. Then there’s the fact that humans can perceive colours differently to each other. Recently I had someone tell me they wanted to match a colour that they had sent me a photo of (on screen) which to me looked very much like black, but they were calling it navy. Turns out it was just a really, really, dark blue. I won’t get into this right now because it’s too mind-boggling.
Colour matching for printThe Pantone Matching System is a global standard of colours for use across the design industry – including for print. It covers colours in all shades with recipes to create each colour, along with special ones such as metallic, pastel, and fluro. Theoretically, you can say to your printer that you would like to use PMS 2096 C and they will know what you want. Making that happen actually can depend on a few different factors. Firstly, if you specify PMS 2096 C – you’re specifying the coated colour – that is, to be printed on a coated stock. While coated and uncoated colours have the same mix of ink, the final result can vary due to a number of factors. It’s important to remember that if you have chosen PMS 2096 C, but the stock you’re using is uncoated, you’ll actually be getting PMS 2096 U – the uncoated colour.
Colour matching for print – coated vs uncoated colours
Pantone 2096 is made up of the following: 22.17 parts Pantone Medium Purple 7.81 parts Pantone Process Blue 2.38 parts Pantone Black 67.64 parts Pantone Transparent White
Colour matching for print from Pantone to CMYKWhat if you don’t want to, or cannot, use the Pantone colour? For example, printing an image that contains colour photos along with your company logo, or printing small quantities digitally. Then you can use the CMYK breakdown. However, while the recipe for an uncoated and coated Pantone colour will be the same, their CMYK values might be quite different. For example, according to the Pantone website, the CMYK breakdown for old mate Ultra Violet should be the following:
- Coated: 76% of Cyan 75% of Magenta 0 Yellow and 0 Black.
- Uncoated: 66% of Cyan 66% of Magenta 0 Yellow and 0 Black.
