Specialist High Quality A3 Poster Printing

We specialise in individual and low volume high quality prints suitable for a range of uses including CAD drawings and fine art prints. We only print using genuine 8-colour Epson inks and printers which guarantee sharp, vibrant, colour saturated prints every time.

Unbeatable Quality and Prices

Our perfectly – proportioned A3 posters are printed up to a stunning 1440dpi and come in your choice of matt, satin and photo gloss finish with laminate options available. Not only do we offer premium quality materials and production on all of our posters, we will price-match any of our UK competitors who sell the same quality of product for less.

Choosing the Right Finish for Your A3 Poster

We offer five options of paper finish for your poster: matt, satin, photo gloss, pastable paper, and plastic paper.

Matt Premium:

Matt poster paper doesn’t reflect light and is well suited to black and white posters, less detailed posters, and posters that will be viewed in well-lit settings. A key benefit of matt poster paper is that smudges aren’t visible on it so you don’t have to worry so much about keeping your poster clean.

Satin Premium:

Satin poster paper provides a middle ground between photo gloss and matt paper. It showcases colours, details and contrasts very well, but doesn’t produce as much glare as photo gloss paper. Smudges are also less visible on this type of paper so it’s possible to display this type of poster without a protective cover.

Gloss Premium:

Photo gloss paper is reflective and helps to showcase the colours and details of your poster, especially useful if the poster will be viewed in a low-light setting. Photo gloss paper shows dirt and fingerprints so is best covered with glass or plastic. In settings with very bright lighting, gloss paper can be too reflective and mean the graphic is difficult to see from all angles.

Pastable Paper:

Recommended for short term use, the pastable blue-backed paper is designed specifically for outdoor use and is crack and flake resistant – even if it is folded after getting wet. At 125gsm thickness it’s thicker than the industry standard, making it more durable and easier to hang. The blue-backing also prevents the background surface from showing through the poster. This is a budget outdoor poster paper which is often used for events posters and billboards. Due to the texture of this material, the print quality can be reduced compared to printing on other poster material and is recommended for larger posters viewed from a distance. The blue-backing on the material may result in artwork darkening slightly.

Plastic Paper:

The SyntiSOL plastic paper is self-explanatory, it's plastic paper that is perfect for outdoor use. It is an extremely weatherproof and durable material with a satin finish that produces excellent print quality. We recommend this paper type if your poster will be viewed from close range, such as point-of-sale displays and entrance posters. The product is guaranteed to stand the test of time if used correctly.

Need a Frame for Your A3 Poster?

A frame is a great way of showcasing your poster and creating a really professional looking display. We stock Trappa poster frames which have an innovative front opening system so you can hang your poster without having to remove the frame from the wall. Trappa frames are a great way of creating easy to renew, professional looking advertising displays with very little effort. The frames are made from anodized aluminium in a choice of silver or black finish and are suitable for outdoor use.

We also stock A3 Poster Frames that are high quality wooden frames in a range of finishes (black, white, brushed silver, and oak), providing a great way to display your A3 prints. The acrylic glaze used in these frames looks like traditional glass but is much harder to break and less hazardous if accidentally broken.

For other standard sizes see our A2, A0, 2A0, & A1 poster printing services or check out our main poster printing page for a full overview of all the poster printing options we offer.
