Your Guide to Image Colour and Size

Your Guide to Image Colour and Size


There are two main colour modes for images; RGB and CMYK. Vivid and neon colours that you see on your screen are generally in the RGB colour mode. However, for professional printing, images need to be in CMYK mode. Here is some more information on these colour modes and how to achieve the best colour images for printing.


RGB (which stands for Red, Green, Blue) is the colour mode used for images that are meant to be seen on screen. Electronic devices are able to create any colour imaginable by adjusting the intensities of each of these three colours of light in each pixel on the display. For designs intended for electronic use RGB is the colour mode you want to use to get the most from your image.


If however there is any chance your design will be printed, for example if you’re sending it to us to be printed on our labels, then RGB is not suitable and you will need to use the CMYK colour mode. CMYK (which stands for Cyan, Magenta, Yellow, blacK) is the colour mode printers work in, as they have to mix ink colours rather than light. Because of these technical differences and the limitations of printing, CMYK colours are less vivid and bright than RGB, so printed images can look quite different to the images on the screen.

Designs For Printing

With this colour information in mind, remember when you are designing artwork to be printed that the on-screen and printed image can look very different if you don’t use CMYK colour modes. Most design software such as Adobe Photoshop and Illustrator have the option to change the colour settings. We also recommend doing a test print on your printer at home before sending us designs to ensure that you are happy with the colours. If you have any queries about this do not hesitate to contact us and we’ll help to design a top quality image that will be the perfect colour when printed.


The size of the image is also extremely important when designing and printing, and again, screens can be deceiving. There are two important elements of image size to consider when designing artwork to be printed and they are: dimensions and resolution.


Dimensions are simply the measurements of the image and can easily be adjusted in any software your using to design your labels. We ask that you upload or send us artwork that is 100% size that you want printed. If you send us artwork that is a lot bigger or smaller than the size of the image you want printed, then adjusting this might affect the quality.


Resolution is expressed in DPI (dots per inch) and is important for getting a high quality image. For an image on screen to be high quality the resolution only needs to be 72 dpi. However, for the same size and quality image when printing, the resolution needs to be 300 dpi as printer resolution is higher than screen resolution. This is why we ask for images to be as close to 300 dpi as possible.

If your design is not 300 dpi, it is not recommended that you adjust the size of it to 300 dpi in your design software. This will just duplicate the pixels and create a blurry image. It is best if the image is designed at 300 dpi from the start.

Again, if you have any questions about this please do not hesitate to contact us and our designers will guide you through creating the perfect design for printing.
