Setting up your files


What file formats we accept

We can accept files in PDF or JPG format. If you are planning to supply another format, please contact us first.

Poster Printing Information

In order to process your order smoothly and get your job looking perfect please read the below fully.
We will always check your files thoroughly before output and will contact you if we identify any potential issues. If you need advice on how to set your files up please call us on 020 7388 7373

  • We prefer to have files supplied as press ready PDF files if you'e working in Powerpoint, InDesign or Illustrator. If you're working in Photoshop, we just need your file at 100dpi JPG files at actual size. If you have fine detail and small text, then you can work at 150dpi. You do not need to work in a higher resolution than 150dpi. Large format printing is different to litho printing where 300dpi is required. If you're unsure, please call us and we will talk you through..
  • If you're working in Powerpoint, you can supply your file at actual size or a proportional scale. For example, an A4 size enlarges perfectly to A0 size, so you if you prefer, you can work at A4 or A3 size for convenience. At print stage we enlarge your file using our sophisticated RIP software. This ensures that no quality is lost.
  • Do not make PDF files from Photoshop. Supply them as JPG files without compresion - i.e. Maximum Quality. Before printing, we resave your files to TIF format to preserve the quality.
  • Images used within Powerpoint, Illustrator or InDesign: For optimum output, all images at the final printed size should be a maximum of 100dpi - 150dpi. For example if you are producing an A0 poster, and you are supplying a artwork at A4 size create your images at 350dpi - 400dpi. This will give you perfect results at A0 size - i.e. 400dpi image enlarged x 4 = 100dpi (A4 > A0 is a 400% increase)
  • Avoid using images from the internet - they may look good on screen but resolution of these images are very low and your final result may be pixelated.
  • Please do not include bleeds or crops in any file you send us unless requested.
Poster Printing PDF and JPG

Accepted File Formats

Most Applications have a built in 'Save as PDF' option.
Your PDF files should always be set to ‘Press Ready’ or ‘High Quality Print’ if the press ready option is not available. Please do not include bleeds or crops.

Please ensure your JPG file is at least 100dpi at actual size. This is the same as 400dpi at 25% scale.
You do not have to supply your file at the final output size of your job as we can enlarge your file using our RIP software at the time of printing. This is a much better method then enlarging in Photoshop.
Do not make PDF files from your jpg. Supply them as-is. Ensure that when you are saving your jpg file, the 'quality' is left to 'maximum / no compression'. Please do not include bleeds or crops.

Our graphic arts professionals understand what design elements can produce audience focus, capturing and holding attention.  Our premier large format reproductions offer the vibrant colour and

simplicity of a single panel display, or to easily expand to a 4-panel width, the matrix system is remarkably portable and simple to set up.  Using a compact, expandable frame, the matrix system becomes the stage for spectacular large format graphics that can often reproduce your product image at life-size or near life-size proportions.  When multiple graphic panels are incorporated into a matrix design, the effect is seamless and stunning.  Whether your message benefits from a panoramic vista or a jaw-dropping digital image of your newest product, the liquid matrix display system will stop traffic.  Usability is an important factor of any exhibition stand.  We understand your need for immediacy of presentation and simplicity of use.  Your image message must be up and on display to be effective.  At a large attendance event, your support personnel need to be free to focus on incoming traffic, not worrying about the stability or view-ability of their display media.  Our large format displays are transportable in easy to handle, protective carrying bags – specifically designed for use with the particular display option you have chosen.  Set up and take down of both the liquid chromium and liquid matrix display stands can be accomplished in a matter of minutes by one person.  Durability is a premium consideration in any exhibition stand we produce.  We use the finest print products to ensure not only a stunning image, but also to ensure the longest life possible of that image.  Our liquid chromium banner stands use a high quality, high tensile strength translucent film that is light and water resistant.  This lightweight medium beautifully reproduces digital images that can be further enhanced by the ambient lighting in the display environment.  The liquid matrix pop-up display system can play host to a number of print mediums, from luxurious papers to opaque film or fabulous fabric finishes.  Our design team factors in your anticipated use and display environments to ensure the longest product life.  Finding the right exhibition stand for your needs is just a phone call away.  The graphics arts specialists at Liquid Imaging are happy to discuss your needs and your vision of what your message image display is to accomplish.  We offer excellent service, reasonable costs, and the best image reproduction technology in the industry.  Our 1200dpi
