Want to find out more about printing with Dennis Maps? We’re here to help, with five top tips for planning your print job.

Small, medium or large?

Spend some time thinking about what size you’d like your product to be. We’re specialists in large format printing and can print up to 1500mm wide and 1100mm long. At the other end of the print spectrum, we can create items as small as you’d like. Carefully consider what your print job will be used for to help you decide the right size.

Choosing the correct print size


Choose the right resolution

Before you send your artwork over, make sure it’s the right resolution. All artwork needs to be high resolution to create a high-quality print. A high-resolution image is one that has a greater concentration of dots/pixels, making the image sharper and clearer than one with a lower concentration of dots/pixels. Make sure any images you download from the internet are high resolution, as well as checking you have approval to use them. You may want to create your own high resolution artwork using design packages such as Adobe InDesign. Alternatively, you can work with a graphic designer or a specialist cartographer such as Lovell Johns (if making a map). We recommend aiming for at least 300DPI (dots per inch) for your artwork.

Consider colour

We ask that you send your artwork to us in CYMK (cyan, magenta, yellow and key – meaning black). Printed documents are always formatted in CYMK, whereas online documents are formatted in RGB (red, green and blue). If your artwork is the former, you can convert it to CYMK using a design package. Files sent as RGB will print in a slightly different colour to how they appear on your screen, whereas CYMK will appear as it does digitally. It’s also worth noting that text can appear black on screen, but be composed of other colours, and not appear black when printed. Double check that any black text is actually black.

Pick your paper

Have a think about the type of paper you’d like to print on. All papers offer different benefits that work well with some products but not others. We stock four types of FSC-certified paper – gloss, silk, matt and uncoated. Gloss can work well for wall maps and posters. All of these, apart from gloss, can be folded, for products like diagrams and folded maps. Meanwhile, uncoated stock has more texture. We offer paper in 70gsm up to 350gsm. We can fold printed items on paper up to 115gsm. The higher the grammage, the more rigid the paper. The lower end of the scale is suited to items like charts and instruction booklets. We hold a vast selection of papers in stock and will try our best to source any other paper you’d like. You can also choose to print on Polyart, a durable and highly water-resistant plastic film.

Be aware of the print process

We have an easy-to-follow print process at Dennis Maps. Firstly, you’ll contact us with your initial enquiry, from which we’ll get enough details to provide you with an accurate quote. Once you’ve approved your quote, we’ll request your artwork. This should be a high-resolution PDF in the size you’d like it to be printed, with a bleed if required. We’ll check that it matches your quote and proceed if everything is as it should be. We’ll process your files and make sure we’re happy with the quality and size. If all is well, we’ll send you a PDF to sign off. Once approval is received, we’ll make print plates (for litho printing) or go straight to press (if digital). All sheets are guillotined once dry. If there are no further processes, the print job will be packaged and dispatched to you. Packages can be sent to a single destination or multiple locations, within the UK or internationally. The turnaround time is always quick but varies depending on the print job.
