Why is my black colour coming out dull when printed? ( amended and updated )
As somebody who has worked in print for years, I know black can be a troublesome colour to work with when it comes to professional printing! From dull colours, noticeable banding, to the colour being milky and muted. There is a wide variety of headaches when it comes to working with black.
As a former in-house designer at a gifting company, black was a core brand colour I had to wrestle with weekly. I could have burst a blood vessel.
Black can be a royal pain to print, I feel you! In light of a recent project where I had to work with black once again, it reminded me of this post.
This post has just been given a refresh to further help and aid any budding designers or those looking to troubleshoot their problematic black print.


Why is my black colour coming out dull when printed?
As to why your colour black is coming out dull and muted. Dull black in print can be caused by mismatched colour profiles, paper types, poorly calibrated screens, working on dated screen types, wrong settings in your application, variation in printers, and professional printers using professional print equipment compared to your domestic-grade equipment. It can also be due to a lack of colour checks before sending professional artwork to print.
There can be a variety of reasons, all working in conjunction to produce a lacklustre and milky print. These reasons can be a mixture of both software and hardware-related.
To avoid dull black colours, employ a variety of techniques to remedy the issue. Such as running test prints, checking settings in your applications, and working with a printer.
If printing on a domestic printer from your home or office, remember to check that you are not running low on black ink! This can also cause dull or streaky prints.
Investigate the points mentioned above. You may need to take it a step further of look for additional help to resolve the issue.
Working with the colour black in Graphic Design for print
Black can be a trouble to work with when it comes to print, especially with all of the varying print processes, paper finishes and general variations with commercial printing machines. Ink types, screen calibrations, applications and so on – can impact your dull black when printed.
Being empathetic to how black can be problematic to print as a designer myself, both you and I want to put our best foot forward and try to reduce dull blacks and greys. Below is a list of tips and tricks to beating a dull black when printed, which just may fix the problem.

A list of tips and tricks to get the colour black you desire!
Black can be one of the most problematic colours to handle when it comes to design.
Here are some tried and tested solutions I have used to remedy why your black colour is coming out dull when printed.
Tip 1 ) Fixing Black – Consider whether your black is ‘black’

Not everything needs to be pure black. There is black and there is ‘black’. This is more applicable if you are working with photography, illustration or texture and not a black as a block colour.
When working with either illustration or photography, for example, it is common for me to add tones that will either warm or cool my black colour. Black is rarely pure black in the real world. Consider whether any colour or surroundings in your image would be influenced but subtle tints. Black, not being total ‘black’ can be one of the easiest workarounds.
I have added an illustration below to show different tones and hues on a black background and colour to further illustrate my point.
Left to right – reference image below/

( Left ) Flat grey black
Notice that this image is devoid of colour. Presumably, this is only in ‘greyscale’ ( older illustration ), but this still has tone and depth. The colour of this, however, could be more of a gamble when printing based on past experience. These more monochromatic greys and blacks seem to be more prone to branding in Photoshop.
( Middle ) Added tint to black
The middle circle is black with a tint of red, which again could work well in a photo that has relevant colours or tones in the image to influence this type of black. I have added a paragraph below on how to add a hue in Photoshop.
( Right )Adding a couple of subtle colours
The tint added to the circle on the far right is closer to a deep red – reddish black, but perhaps something of this nature would be truer to the nature of artwork or photography being shown and displayed?
For argument’s sake, you could consider adding a slight tint of green or yellow to test and measure.
Test print what you create and gauge some of the warm hues. I have employed similar techniques again in attacking posterization in Photoshop.
Tip 2 ) Check Your Colours – Digital Black Colour in Photoshop
It is always wise to check your colours when working with print, generally, not only black! If your black is arriving with a murky, milky or dirty quality, check your colours by the number, not just by what you see on your screen in Adobe Illustrator or Photoshop.
To follow the first tip of adding a slight tint of colour can be all that is needed to remedy your dull black.
Take note of the CMYK | C=65% M=70% Y=66% K=85% for illustration purposes.
For those who would like to know, the ‘K’ is the black notice, and the black also has a lot of colouration. This is not a rich black or the sort of black used in editorial design for fonts by the way.

Tip 3 ) Breakdown – Avoid dull black in print by checking colours digitally
Before sending your artwork to print, check that your black isn’t the wrong sort of grey or black by either opening the window above or checking that black is represented correctly only on your computer screen. In applications such as Adobe Illustrator, certain preferences will allow you to see black colours in their ‘truer’ form. You can also enable the output as shown.
Tip 4 ) Test print your black design work
Save yourself the worry and heartache and consider running some homemade test prints first. Although a home print is not a substitute for a professional print run, it is better to try and discover any issues with your black colouration before seeing it on a 1000 or so copies of your print run.
Tip 5 ) How your colour black is displayed
** IMPORTANT** This can be a significant contributing factor as to why your black colour is coming out dull when printed. There are options in various graphics programs that can be misleading when working with black. There are options that will allow you to see your black in its truer form compared to what is being shown on your computer screen.
If your black is not coming out as expected, check that your ‘Appearance of Black’ in your applications preferences is set to display blacks as required. ( see screen grab below )
Here is an example taken from Adobe Illustrator showing how a more accurate representation of black can be shown on your screen.

See the image above, notice how – onscreen – Display all blacks Accurately is set? This will help you to see how your black may come out in print. Allow yourself to see!
Tip 6 ) CMYK vs RGB vs GreyScale Printing
By default, most designers who were taught to work with 4 colour print were taught to work with CMYK. CMYK, in comparison to RGB can be seen as the poorer cousin colourwise! This is the profile you must work with most printers unless they state otherwise.
However, it is common practice for printers to work with CMYK and should follow suit with this unless stated otherwise.
RGB ( Red, Green, Blue ) is the 3 colour profile I tend to work with more now for digital and website design. RGB is also by far my favourite to work with, however, RGB is better suited to screens which can display millions of colours. You may notice that your vibrant colours and hues suddenly become dull and muted if you switch to CMYK towards the latter end of the design process. By default, RGB is best left to work with screens for final output for print. CMYK for print. Here is an example website design project where I have gone to town with RGB.

Greyscale, brace yourself for mono colours. However, this can work well for simple black and white line drawings with an absence of colour.
Tip 7 ) Work with your printer to avoid dull greys and blacks
It can pay to work closely with your printer in the first instance to avoid headaches and dull black colouration coming out in print. Ask your printer how they’d prefer to receive the artwork. Most professional brick-and-mortar printers will request that your file be supplied in CMYK and as PDF’s in the ideal world. Although that can only now be used as a guide and not a hard and fast rule.
Graphic Design Question: Why is my black print coming out dull grey and not black?
The reason that your black colour is coming out grey and not black as intended, could be that the colour is grey and not black! Certain options in your preferences in your graphics programs may be showing dark greys as black and misleading your eye.
To fix this, you will need to check that the preferences in your graphics application are enabling you to see all black colouration in its true form.
Another reason that your black is printing grey could be due to screen calibration and screen brightness.
Now less common, some of the worst screens for displaying black are TFT screens. As you can still get on some budget laptops, i would recommend rigging your laptop to a screen that enables better representation of colour and colour depth.
Although I have had to use TFT screens in a professional setting in the past, I would recommend using a screen which can show a better range and depth of colour – including black. TFT screens are awful for seeing colour in print.
Why is my black colour coming out dull when printed? Summary takeaway
The reason behind your dull black and almost grey colouring when printed could be down to a range of issues. Some of these issues and causes can extend beyond this list. It is a problem that needs a bit-by-bit approach to find out what is causing the problem in the first place.
I would check that you have your colours and preferences set correctly. Making something CMYK isn’t enough to avoid off-colouration when printing with black.
It is also worth being mindful that any web-based print of design software used for proofing can be problematic when trying to get true representation of your colour. These web programs and can deviate from typical standards used by professional printing companies.
These misrepresentations can include low-res proofs, misrepresentation of colour, and poor representation of bleed. What you see, isn’t always what you get.
Why is my black colour coming out dull when printed? Bonus Tips
- Take Notice of the colour warnings when you are in the colour picker window. This could save a lot of headaches later on.
- Let the printer do the legwork. Send your artwork to the printer and try to let them help you. A printer worth their salt will want to help you and have your return custom. To reinforce your expectations, send them a physical sample from your home printer – assuming you have a good-quality home printer.
- A HUE, if you are working on an image with a lot of dark areas, why not add a little hue / tint of colour? 20% cyan, for example or some magenta/red for a warmer image.
- Avoid working with 0, 0, 0, 100 K, as this is best reserved for font/text printing and can your work charcoal appearance. Use a ‘Rich black’ or ‘designers black’ instead. 20, 20, 20, 100 k for example.
- Avoid 100, 100, 100, 100, CMYK as this is reserved for crop marks and using this colour can drown the paper – no one wants drowned paper!
- Don’t be fooled. Your screen can be way out of sync with your printer. Do some tests first and see what results come from your printer. Even printing on your home printer cannot guarantee the finish you require when you send your work to print.
