How We Use Colour
It’s important to note that, here at GomiePrint, we don’t check documents’ colour set up, and our Design Online tool automatically converts all colours to CMYK, which can cause noticeable colour variation in the finished product. So, make sure to check your proofs before you send those over to us (we’ll cover how to do this in this guide).
With RGB colours, the graphics are made up from Red, Green and Blue, whereas with CMYK the colours are made up from Cyan, Magenta, Yellow and Black.
CMYK colours are subtractive – this means that the starting canvas is white and as colours are added, it gets darker and darker until it’s black. RGB colours are the opposite; they’re additive, which means you start with a black canvas and colours are added to create the final image.
Why Do Print Files Need to be CMYK?
The RGB colour spectrum is huge – much larger than the CMYK spectrum. This means that some colours, like fluorescent orange and green, aren’t available within the CMYK spectrum. Commercial printing presses, like ours, print onto white paper, so to get the best end product it’s a really good idea to convert your designs to CMYK before you send it to us.
Even if you send an artwork file in that’s not set up in CMYK, we’ll automatically change it for your when we send your proof. However, this could cause slight colour changes. Here’s an example of files that have been automatically converted before going to print.
Converting RGB Files to CMYK and Re-Balancing Colour
If you’re using software like Photoshop, you can choose to convert colours to CMYK and then readjust the colour balance afterwards. If you’re using RGB elements, it’s worth converting these into CMYK and re-balancing the colours during the design process.
Creating Files in CMYK
The easiest way to design artwork for print is to set up and design the whole document in CMYK colour. This will save any problems trying to adjust colours afterwards, which can be quite difficult. Not all software has the ability to create files in CMYK colour (like Microsoft Word and PowerPoint).
If you send us a Word or PowerPoint document, for example, we’ll convert it from RGB to CMYK colour and then send a proof back to you of how this will look. Below you’ll find my guides for: Adobe Photoshop, Adobe InDesign, Adobe Illustrator and Microsoft Publisher.
You’ll set your colour settings in Photoshop when the document is first created. Look at the first image below to see the right settings for CMYK.
You can check the settings when the document is open too by clicking on ‘Image’ at the top of your screen and then ‘Mode’.
When you’re working with InDesign, the colours will be automatically converted to CMYK when the file is exported to PDF by selecting the option: PDF/X-1a:2001.
Like Photoshop, you can set the colour settings when you first create a document in Adobe Illustrator. If you want to convert the colours in an existing file:
To convert your colour settings in Microsoft Publisher (2003 or later. For the 2016 version there is no way to change the colour setting) first of all open up your document.
If you’re using any other kind of software, your key settings to make sure you’ve got set up are:
