When ordering architectural or construction drawings, one of the decisions you may need to make is whether to print your plans in black and white or colour. Both options have their advantages, and the right choice will usually depend on how the drawings are going to be used.
For many construction projects, black and white plan printing is more than sufficient. However, colour can be extremely useful when drawings rely on highlighted areas, different services or visual annotations.
Here is what to consider before placing your next plan printing order.
When is black and white plan printing best?
Black and white printing is commonly used for architectural drawings, floor plans, elevations and general construction documents.
Most technical drawings are designed using clear line weights, symbols and annotations that remain easy to understand without colour. This makes black and white plan printing a practical choice for everyday site use, particularly when several copies of the same drawing are required.
It can also be a cost-effective option when printing larger quantities of A0, A1 or A2 plans.
For straightforward drawings where colour does not communicate any additional information, there is often little benefit in paying for colour printing.
When should you print plans in colour?
Colour plan printing becomes useful when different colours have a specific meaning within the drawing.
For example, colour may be used to distinguish:
- Electrical, plumbing and mechanical services
- Different construction phases
- Revised or amended areas
- Site boundaries and landscaping
- Materials or finishes
- Specific rooms or zones
In these situations, converting a drawing to black and white could make important information less obvious or, in some cases, difficult to distinguish altogether.
Colour can also make presentation drawings easier to understand when plans are being shown to clients, homeowners or other people who may not regularly work with technical drawings.
Is colour plan printing more expensive?
Colour printing will usually cost more than black and white printing, particularly when ordering large format plans.
However, the cheapest option is not always the most practical.
If colour is being used to communicate important information, printing the drawing correctly can help avoid confusion and make plans easier to interpret on site. It may also save time if contractors can identify key details quickly.
For projects with a large number of drawings, you could use black and white for standard plans while only printing selected drawings in colour where it adds genuine value.
Which is better for construction site drawings?
For general construction drawings, black and white is often the preferred choice. Clear linework and strong contrast make plans easy to read, while the lower cost can be useful when several sets are needed.
Colour may be better for specialist drawings, marked-up plans or documents where different elements need to be identified quickly.
It is also worth checking the original PDF before ordering. If the drawing contains important colour-coded information, make sure this will still be understandable if you choose black and white printing.
Choosing the right option for your plans
There is no single best option for every project. The important thing is to consider how the drawing was designed and how the printed copy will be used.
If colour does not add any useful information, black and white plan printing is usually a simple and effective choice. If your drawings rely on colour to communicate important details, colour printing can make them much clearer.
