Whether you’re ordering business cards, brochures, leaflets, or large-format posters, image resolution can make the difference between a professional-looking print and one that falls short of expectations. Customers often tell us their artwork looks perfectly sharp on screen, only to find it doesn’t look the same once printed.

The good news is that understanding image resolution isn’t as technical as it sounds, and a few simple checks can dramatically improve the quality of your finished print. As experienced Brighton printers, we help businesses and charities prepare artwork every day. This guide explains everything you need to know before sending your files to print.

What is image resolution?

Image resolution refers to the amount of detail contained within an image. Think of a digital photograph as being made up of thousands of tiny squares called pixels. The more pixels an image contains, the more detail it holds and the better it will reproduce when printed. In professional printing, resolution is usually measured in DPI (Dots Per Inch). The higher the DPI, the sharper and clearer your printed image will appear. For most commercial printing the industry standard is 300 DPI at the final printed size.

Why does artwork look perfect on screen?

Computer monitors, tablets and mobile phones display images using light, making colours appear brighter and images appear sharper than they often are. A low-resolution image can look perfectly acceptable on a laptop because screens only display a fraction of the detail required for professional printing. Printing is much less forgiving. Once ink is transferred to paper, every detail becomes visible. If an image doesn’t contain enough information, the result may appear soft, blurry or pixelated.

Why image size matters

Resolution isn’t just about the image itself it’s also about how large you intend to print it. Imagine you have a small photograph that looks fantastic on your phone, it might print beautifully on a business card but become noticeably blurred if enlarged to an A2 poster. Likewise, logos copied from websites are often only suitable for online use. Stretching these images to fit a leaflet or brochure can quickly reduce quality. This is why professional printers always ask for the highest quality version of your artwork wherever possible.

Understanding DPI without the jargon

You’ll often hear designers and printers talking about 72 DPI, 150 DPI and 300 DPI. Rather than focusing on the numbers, it’s easier to think about what they’re used for. Images intended for websites or social media are usually created at around 72 DPI, keeping file sizes small so pages load quickly. Professional print requires considerably more detail, which is why 300 DPI has become the industry standard.

Why social media images shouldn’t be printed

One mistake we see surprisingly often is customers downloading their own images from Facebook or Instagram before sending them for print. Unfortunately, these platforms automatically compress images to make them load faster online. Although they may still look sharp on your screen, much of the original image data has been removed. Whenever possible, always use the original photograph or design file rather than downloading it from social media.

Vector graphics vs photographs

Not all artwork behaves in the same way. Photographs are made from pixels, meaning they can lose quality when enlarged. Logos, however, are often created as vector graphics. These use mathematical paths instead of pixels, allowing them to be scaled to virtually any size without losing quality. If you’re printing business stationery using a vector version of your logo will always produce the sharpest results.

Resolution isn’t the only factor

Although resolution is important, it’s only one part of producing great printed materials. Colour setup, bleed, margins and file format all contribute to the final result. For example, artwork designed in RGB may look slightly different once converted to CMYK for professional printing. Similarly, missing bleed can leave unwanted white edges after trimming. Preparing print-ready artwork involves bringing all of these elements together.

A few simple checks before you print

Before sending your artwork to your printer, it’s worth taking a few moments to review everything carefully. Zoom into your images and look for any signs of pixelation or softness. If an image already appears blurry on screen at full size, it’s unlikely to improve when printed. Check that your document is set to the correct dimensions, your images are high resolution, and your fonts have been embedded or outlined correctly. These small checks can prevent delays and help achieve a much better finished result.

Professional printing starts with professional artwork

Whether you’re producing leaflets, flyers, business cards, brochures or large-format printing, the quality of your artwork has a direct impact on the quality of the finished product. Investing a little extra time in preparing your files properly helps ensure colours are vibrant, images are crisp and every printed piece reflects your business in the best possible way.
