We digitally print our flags in-house at our head office in Cambridgeshire, ensuring all our flags are produced to the highest quality.
We use advanced dye sublimation printers for all our fabrics. Dye sublimation helps us create vivid, full-colour displays. As standard, all our flags are produced mirror image—your designs will be clear on the front and reversed on the back.
If you need your design to read correctly from both sides, you'll need a double-sided flag. These are not currently available through our webshop.
We always recommend mirror image flags for their durability. Double-sided flags are heavier, harder to display, have a shorter lifespan, and can cause damage to flagpoles.
Finally, choose your flag finishing. Our standard flags are finished with a rope and toggle for mounting to flagpoles with halyard. We also offer eyelet or D-ring finishes. (Please note: flags with top sleeves cannot be finished with a rope and toggle.)
Installation
Whether you need installation at a single site or across the UK, our team can assist. We offer one-off installation services as well as contract-based support to keep your flags updated for seasonal promotions.
We also provide a full range of flagpoles, maintenance services, and all types of flagpole installations.
Printing Methods
Digitally Printed Custom Portrait Flags: Digital printing is ideal for small and medium-sized runs (1–100 flags), offering cost efficiency and fast turnaround. Our advanced printers can handle both double-sided and mirror image prints in any design or colour.
Ask us about our new Pollutant eating coating which we can apply to your flags!
EnhanceAir®, Powered by PURETiTM Light-activated coating that destroys air pollution.
When applied to outdoor advertising media, EnhanceAir turns any treated material into an air purifying surface that not only enhances human health, but contributes to the fight against global warming.
The coating is transparent and does not impact the appearance or durability of the ad itself.
Typically applied as the last step in the printing process.
No changes are required in the installation process.
It does not affect the recyclability of the material.
THE SCIENCE OF ENHANCEAIR: PHOTOCATALYSIS
When UVA light energy activates the coating, it starts a chemical process that turns nearby oxygen and water vapor into two powerful cleaning agents (OH-* and O2-*)
• These two cleaning agents convert pollutants into harmless minerals and gasses.
• The active mineral is a catalyst, so it is not consumed in the process. It continues to work as long as it is on the surface and has access to humidity and light.
• The process happens only at the surface and repeats constantly to clean the surface and the air that comes in contact with it.
Why NOx?
Nitrogen oxides (NO and NO2) are formed during combustion. NOx is harmful in several ways:
• It irritates airways and increases susceptibility to allergens.
• It combines with other pollutants in the air to create smog, acid rain, PM2.5 and ground level ozone, which contributes to global warming.
• Increases risk of heart disease, stroke, COPD, and lung cancer.
• It has a much higher Global Warming Potential than CO2.
NOx is an indirect greenhouse gas. It does not trap heat directly, but leads to the creation of other gases, like ozone, that are greenhouse gases. It is included on the list of gases that countries report in their greenhouse gas inventories.
EnhanceAir fights climate change and improves human health by destroying NOx and other pollutants. It helps lower the greenhouse gas footprint, but not the carbon footprint.
Proven Laboratory and Real World Results
Using a test based on the ISO 22197-1 standard, we pass a fixed amount of NOx across a treated surface where the air is in contact with the surface for only 1 second on average before being replaced by new polluted air at the same concentration. The concentration of NOx is measured as it exits the chamber.
We offer a wide range of custom portrait flag materials, each with unique characteristics suited to different conditions. Our most popular materials include:
Standard Knitted Polyester
Used in over 90% of flags produced in the UK. Suitable for both indoor and outdoor use, ideal for mirror image printing.
Polymesh
50% more durable than knitted polyester. A permeable fabric suitable for mirror image flags and medium to long-term use.
ECO Knitted Polyester
Made from 100% recycled materials. Around 2 plastic bottles are used per 1sqm of fabric. Delivers vibrant, eco-friendly results with crisp design clarity.

Accepted File Formats:
Adobe Illustrator (.ai)
Encapsulated PostScript (.eps)
Portable Document Format (.pdf) - Preferred
Scalable Vector Graphics (.svg)
For our print purposes, we prefer artwork created in Adobe Illustrator and saved in a PDF format. Vector graphics are ideal as they are easy to scale and produce better print quality.
Resolution Requirements:
For Raster Images:
150 DPI at 100% of the final size
300 DPI at 50% of the final size
DPI (Dots Per Inch) measures the detail of an image. Increasing the size of a raster image can lead to blurriness or pixelation, which may not be visible on a computer screen but will show up in the final print.

As all of our portrait flags are made bespoke we do not have a standard size, however, our most popular size is 0.9m x 1.8m.
