1. Understanding Black in CMYK

In the CMYK colour model, "K" stands for black, with a setting of 100% K producing what we call "standard black." However, standard black, or "plain black," relies solely on the black ink and can lack depth. Super black, on the other hand, combines black (K) with small amounts of cyan, magenta, and yellow to produce a richer, more intense black that appears less washed out on paper.

In print design, super black is particularly useful for:

• Large black areas or backgrounds that need to stand out
• High-contrast areas where sharp, deep blacks are important
• Achieving consistency when black is adjacent to other dark colours or rich imagery

Plain black can sometimes look weak and unprofessional when printed, especially in high-end projects. Adding extra CMY values makes your black deeper and allows it to blend more seamlessly with surrounding colours, giving your artwork a polished, vibrant look. SW19 Design and Print recommends super black to give your designs that extra depth and professional finish.

3. Creating Super Black: Recommended CMYK Mixes

For most print applications, here are tried-and-tested CMYK mixes for super black:

• Offset Printing: C: 60%, M: 40%, Y: 40%, K:100%
• Digital Printing: C: 30%, M: 30%, Y: 30%, K: 100%
• Neutral Rich Black (for balance without colour tint): C: 50%, M: 50%, Y: 50%, K: 100%

Each mix gives a deeper black, but it’s essential to test with your printer first, as different printers and paper types can affect the final appearance. SW19 Design and Print can recommend the ideal CMYK blend for your specific project, based on the type of printer, inks, and paper they use.

4. Avoiding Colour Shifts

While adding CMY values to K enhances black, it can sometimes introduce unwanted tints. To avoid colour shifts:

• Use balanced mixes for neutrality: Equal parts cyan, magenta, and yellow will reduce the chance of your black leaning towards a blue, green, or brown hue.
• Test small sections of your artwork to make sure the super black appears neutral on your chosen paper.

For peace of mind, SW19 Design and Print can provide sample proofs, allowing you to check the black tones before committing to the full print run.

5. When to Use Plain Black vs. Super Black

Knowing when to use super black vs. standard black is key

• Use super black for large areas like backgrounds or solid black blocks. This gives your printwork a more professional look
• Use standard black for text (especially small text), as super black can sometimes cause slight blurring or misalignment with multiple ink passes, particularly in digital printing.

A guide by SW19 Design and Print can help you make these decisions, ensuring you’re always using the right type of black for the job.

6. Working with Your Printer

• Consult your printer to confirm that the super black CMYK mix will work well on their presses.
• Request a proof if possible, as this will show exactly how the black areas will appear once printed.
• Discuss paper type with your printer, as uncoated or matte papers can make super black look less intense. Coated or glossy paper will make colours appear more vibrant, including super black.

7. Tips for Using Super Black in Design Software

Most design software, such as Adobe InDesign, Illustrator, and Photoshop, allows you to customise your CMYK values. Some tips include:

• Create a custom swatch for super black in your design software to use consistently across projects.
• Avoid mixing RGB and CMYK when creating super black, as it can lead to unexpected results. Always set your document colour mode to CMYK for print.
• Use high-resolution images and graphics, especially if you’re combining super black with other dark colours.

SW19 Design and Print can assist with setup in design software, helping ensure that your files are perfectly prepared for print.

8. Final Checks Before Printing

Before sending your artwork to print:

• Check your colour settings to ensure consistency across all elements of your design.
• Convert spot colours to CMYK if necessary, as combining spot colours with super black can sometimes produce unexpected results.
• Ensure that black overprint settings are correctly applied, especially if super black overlaps other colours or images.

For a seamless print experience, SW19 Design and Print can help you run these final checks, ensuring that your project will print exactly as expected.
