Understanding Your Firm's Poster Printing Need

If you require posters for displaying various visuals, you'll want to determine what your business needs to determine the best poster printer.

For example, consider the purpose of the poster. Is it a promotion for a company event or a display of artwork? If so, your design should use an appealing combination of visuals and text to attract attention. Often, posters will feature bold colours and eye-catching headlines by using high-quality images on equally high-quality paper.

Meanwhile, artistic poster designs will often feature more colour and use various design elements to accurately realize an artistic vision.

Ultimately, knowing the type of poster and your target audience will guide your poster design as you determine how to print a poster that meets your unique application needs.

Preparing Your Designs for Poster Printing

As you learn more about how to print a poster, you should also figure out the right design specifications to maximize quality.

When printing a poster, the following are some specific design considerations when preparing a printing project:

Image Resolution and Size

One main consideration pertains to the poster's size and resolution. While you would measure image size using inches or centimetres for height and width, you would measure image resolution in pixels per inch (ppi) or dots per inch (dpi). Using both measurements can ensure you print a high-quality image.

First, consider the size based on what you want to convey. If you want people to read your poster from a distance, you'll want a larger print size. Sizes for posters frequently range from A3 (297 mm x 420 mm) to A0 (841mm x 1188mm). Ensure your design and print sizes are aligned, or you could wind up with a low-quality or improperly sized print.

For large-format print jobs like posters, you'll want to use a minimum resolution of 150ppi/dpi.


When designing your poster, you should know the difference between Red, Green, and Blue (RGB) or Cyan, Magenta, Yellow, and Key/Black (CMYK) colour modes. While RGB is good for digital visuals, you'll want to use CMYK for printed posters, as this colour mode indicates to printers what kind of ink mix will be necessary for an accurate print.

File Type

Ideally, you should save your poster design in both PSD and JPEG image file formats. While the PSD file contains the various layers of all design elements, the JPEG version will convert everything into a single layer that's better suited for printing.

Setting Up the HP DesignJet T850 for Poster Printing

Once you've figured out all the design specifications, you can print your poster with the innovative HP DesignJet T850. This printer makes it easy to discover how to print a poster in the highest quality and with consistent efficiency.

The following are some key steps when setting up the T850 printer.

1. Connect the Printer to the Computer With the Poster Design

To begin your printing project, ensure the business desktop or another computer containing the design connects to the printer. You can do so using a wireless connection that allows you to set up your printer in nearly any space.

2. Load the HP DesignJet With the Right Paper Rolls

The next step is to load the printer with the correct paper rolls. These rolls should be of the correct size and material based on your poster design. The T850 can work with various materials, including bond and coated paper, film, technical paper, polypropylene, and photographic paper.

3. Configure the Print Settings as Required

The T850 also makes it easy to configure print settings that align with your designs. You simply need to know the poster dimensions to give you some clear guidelines.

Specifying Poster Dimensions

Determine what poster dimensions will work with your design, which will help ensure the print comes out at the right size and resolution.

4. Install Any Necessary Software to Complete the Print Job

You will also need to install the correct software to facilitate your printing project. To simplify this aspect, the T850 includes two different types of software, including HP Click for Windows and macOS, along with the HP app for Windows, macOS, iOS, and Android.

5. Conduct Test Printing

Before finalizing the print, ensure the best quality poster printing project by conducting a test. See how the results are with your first print and determine if it meets your needs.

Printing Your Poster and Post-Printing Considerations

After printing your poster, you may also want to finish the design with post-printing processes. Some potential processes that can finish your poster include:

  • Cutting
  • Lamination
