How to Print High-Contrast Designs with a Plotter

Knowing how to print in high contrast allows professionals to create projects with bold colours, deep blacks, and sharp lines. These features are essential for prints such as architectural drawings, graphic designs, and technical plans. However, achieving the right balance of contrast without losing detail can be especially challenging in large format printing. Careful attention to settings, media, and colour management is the key to producing vivid, crisp results when printing high-contrast designs with a plotter.

Here, we'll share everything you need to know about how to print in high contrast. You'll learn how to prioritise high contrast in printing through:

• How to prepare design files with enhanced contrast and resolution
• Tips for selecting the ideal print settings for maximum clarity
• Choosing ink and media types that bring out the depth of dark tones and highlight brightness in light areas
• HP plotter features, such as high-resolution print modes and advanced colour management tools, that make it easier to create stunning, high-contrast prints consistently
• How to leverage your plotter's capability to create professional, eye-catching prints that bring out the full potential of your designs

Learning the basics of high-contrast printing will help you understand how to print in high contrast and avoid common challenges that are likely to arise in the process.

High-contrast printing is the process of creating a print with dark and light tones and a few graduations in between. It delivers intense, saturated colours and clean lines. Black and white are often used to create contrast, but many colour combinations can be equally effective.

High contrast can be used in striking designs, photography, and architectural prints to ensure specific aspects of the print stand out. For instance, it can make blueprints more readable and draw attention to focal points in various designs.

Without the right preparation, prints typically fail to meet user expectations. A range of issues can make prints appear muddy, faded, too dark, or off-colour. Challenges may be related to your monitor's brightness, low-quality ink, subpar software, and poor connections.

Common challenges include:

• Dark images
• Inaccurate colour
• Lack of detail
• Images or prints that fade quickly

Preparing your design before printing will help you avoid common challenges to achieve the expected results.

High-quality editing software allows you to access a range of adjustments to support colour management for high-contrast designs. These platforms include a contrast/brightness tool to change the number of shades between an image's lightest and darkest areas. Drag the slider that controls contrast to the right to increase an image's contrast until you get the desired result. Some platforms allow you to achieve more advanced contrast differences by adjusting the image's tonal range using layers and histograms.

Whether printing text and lines or detailed images, background colours contrasting with focal points will help specific objects stand out. Black and white offers the highest contrast level, but it's inappropriate for all projects. Using tools like a colour wheel can help you choose complimentary colour combinations with high contrast levels.

Knowing how to print in high contrast also involves technical file elements. Deciding the right file formats and high resolution will help you achieve high-contrast prints. Detailed prints typically require a minimum resolution of 300 DPI. Increasing resolution can improve contrast and clarity in a print, especially when scaling is required.

Also, file formats that have improved clarity often require larger file sizes. TIFF files are typically advised for support of layered images and high-quality prints with complex layouts.

The default settings on your plotter will not usually support high-contrast printing. Some simple adjustments will help you achieve the results you want. These options will refine your approach to printing in high contrast.

Manually adjusting colour settings and contrast before printing allows you to override plotter defaults to create higher-contrast prints. In the printer driver setup window, select manual for colour/intensity. A manual colour adjustment dialogue box will allow you to adjust the colour saturation between low and high. You can then adjust brightness and contrast as needed.

Many plotters are optimised for high speeds, which can compromise detail quality. You can change your print quality by opening the “Properties” dialogue box and choosing “Best” under the “Print Quality” tab. Along with improving print quality, higher resolution will apply more ink to the page to provide more saturated colours. Increase the print resolution above 300 DPI for improved colour saturation, creating higher contrast prints.

High-quality ink and paper significantly impact the contrast you can achieve. Always use manufacturer-recommended inks in your plotter to achieve optimal results. Choose high-quality opaque paper for proper ink distribution without smudging or fading. Glossy papers can enhance contrast and saturation of colour. As a final element of printing in high contrast, ensure you set your print profile to match the type of paper you choose.

HP plotters provide users in various industries with specialised features to enhance detail and achieve high-contrast prints. So, consider how these tools can help you meet your goals.

HP plotters enable users to decide print quality related to their needs. By selecting "Best" from the print quality options in printer properties, the plotter works slower to produce prints with improved saturation and higher overall quality.

HP's advanced colour management tools allow users to enhance colour management from the printer driver. Check “Advanced Colour Adjustments” in the printer dialogue box to make adjustments using sliders for colour saturation, brightness, and more.

The HP Image Editor allows users to optimise designs for printing with enhanced contrast control. Users can adjust colour saturation, brightness, and contrast to create high-contrast prints with vibrant colours.

Issues with saturation or subpar colours can interfere with your best efforts to achieve high-contrast prints. Follow these tips to address some of the most common challenges users face.

Ink and paper quality are the top factors in producing clear and vibrant images. Use manufacturer-recommended inks and high-quality paper for high-contrast prints. Check your print settings to ensure your paper selection matches the paper in your plotter. Examine the print resolution and colour intensity before printing. Increasing resolution and colour intensity can help you address fading.

Colour saturation allows you to create prints with the colour vibrancy you desire. Begin by manually adjusting the contrast for your design in your editing software. Next, adjust the colour intensity on your plotter to apply more saturated colours.

High ink saturation can lead to smudging and ink bleed, which ruins the clarity of your prints. Printing on glossy paper can also contribute to smudging. Increasing drying time and choosing the proper paper in your print settings can help limit smudging and ink bleed.

If you frequently print high-contrast images or graphics, planning ahead can help you consistently achieve the high-quality results you seek.

Plotter calibration ensures colour consistency and overall print quality, ensuring the desired results with every print. Routinely adjust colour and paper calibration to address image quality issues or environmental factors.

After calibration or other adjustments, running test prints can ensure you get the expected results and avoid print errors. Print a test plot and measure the resulting print to ensure calibration and other colour or contrast adjustments are correct.

Proper maintenance is vital to keeping your plotter in optimal working order. Along with routine calibrations, steps like nozzle checks, cleaning print heads, and regular use keep your plotter working as expected.

Knowing how to print in high contrast is the first step, but the right equipment matters just as much. Large format plotters are the ideal tool for creating high-contrast images and graphics required by professionals across various industries. Achieving optimal results requires a high-quality plotter and specialised techniques. HP has long been a leader in providing print professionals with tools that help them excel in their industries.
