Colour Accuracy: How to Optimize Construction Printing

Colour is an essential part of architectural and construction printing. It helps to communicate the designer’s intent, improve precision, and ultimately lead to effective project execution. Several factors can affect colour accuracy in printing, including the type of printer, the colour profile, and the file format.

Today, we’ll explore the significance of colour accuracy in architectural and construction drawings and some best practices to help you get it right.

What is colour accuracy in construction printing?

Simply put, colour accuracy refers to the degree of precision in replicating the colours seen on a computer or device screen when construction drawings are printed on paper.

When collaborating on a construction project, it is crucial that all stakeholders perceive consistent colours in their respective copies of the drawings. This consistency helps prevent confusion, ensures accurate decision-making, and maintains the integrity of the design intent throughout the project lifecycle.

Why colour accuracy is important in construction and architectural drawings

Colour is an important part of architectural and construction drawings. It enhances the clarity and readability of your drawings. It also helps stakeholders to better understand the various design elements in your drawings — details like material selections and spatial relationships are also easier to discern. For example, the accurate depiction of materials like brick, wood, or concrete will go a long way to aid in visualizing the final construction result.

Colour accuracy also helps maintain the integrity and quality of your work — especially when there is a good level of consistency across all pages in your drawing. For instance, poor print production may mean that some pages are clean while others appear faint. This jeopardizes the overall output of your printed drawings. Typically, you’d want to deliver high-quality and well-detailed construction prints to your clients.

Common colour issues in construction and architectural drawings

Three common colour issues in construction and architectural drawings include colour shifts, banding, and inaccurate renderings of specific hues. Here, we’ll look into these issues and their possible causes.

• Colour shifts

Colour shifts occur when the printed colours do not accurately match the original colours of the design. The printed output may appear slightly different, with a shift towards a different hue or saturation level.

Colour shifts in your printed drawings can be caused by factors such as inconsistent colour calibration between devices or variations in ink or toner quality. It may also occur due to mismatches between the chosen colour profile and the printing technology.

• Banding

Banding refers to visible horizontal or vertical lines or bands that appear in the printed output. These lines disrupt the smooth gradient of colours on your drawings, making the print look uneven or distorted.

Banding can be caused by issues such as low printer resolution, improper print head alignment, or limitations in the printer’s ability to accurately reproduce subtle colour transitions.

• Inaccurate rendering of specific hues

When specific hues in your drawings are inaccurately rendered,  it means that certain colours are not reproduced as-is in the printed output. As a result, some colours appear too vibrant, too dull, or completely different from the intended shade.

Factors contributing to inaccurate hue renders include limitations of the printer in accurately reproducing certain colours within the colour gamut – the range of colours that can be produced by the printer. Improper colour management settings and incorrect colour profiles are also potential causes.

Best practices for preserving colour accuracy in printing construction drawings

Now, working with a construction printshop like PrintMyDrawings that factors in the importance of colour accuracy is one way to tackle potential challenges with your print colours. But, what can you do during the design phase to ensure that the files you share are printed to match your preferences? Two things you must get right — colour profiles and file formats.

• Colour profiles

Colour profiles are a set of instructions that define how colours should be displayed or printed. Typically monitors and printers interpret colours differently. Colour profiles help to bridge the gap between these devices and ensure consistent colour representation across both platforms. Common profiles to use are CMYK and RGB.

• File formats

It’s essential to use the right file formats especially when you’ll be working with an online construction printshop. File formats like .pdf, .7z, or .Zip will help you preserve colour information accurately.

Overall, paying keen attention to these two important factors will help you ensure that you get construction prints that match your colour specifications and preferences.
