Image file upload guide

When you upload a file for print it needs to be the correct aspect ratio, color profile  and a high resolution. We recommend using Photoshop (or similar software) and to save your artwork as a PDF file.

Please follow this guide for the best print result.

How to export your file in Adobe Photoshop (recommended)

Here’s a quick guide to edit and export your artwork in a printable PDF format using Adobe Photoshop.

Design tips we’ll cover are:

• Setting up your canvas
• Adding and placing an image
• Exporting the PDF document

Setting up your canvas (document)

  • Open Photoshop.
  • Go to File > New.
  • Create a file (document) with the correct aspect ratio for your print (etc. 1:1.41 for A5, A4, A3, A2 and A1 which we recommend).
  • If possible your document width and height should (at minimum) be the size you want your print (etc. 42 x 59,4 cm. for A2).

Example: If you wish to print your artwork in a A2 size you should make sure your image file can fit on to a 42 x 59,4 cm document size without stretching the image as this pixilate and ruins the resolution.

  • If you wish to print your poster in different sizes with the same aspect ratio (etc. 1:1.41 for A5, A4, A3, A2 and A1) you should set your height and width to fit the largest poster size you want to print.

Example: If your image file can fit on to a A2 document size (42 x 59,4 cm) it can also be printed in a A3, A4 and A5 size as these are the same aspect ratio but does not require a higher resolution. However it might not be suitable for print in a A1 size as eventhough it is the same aspect ratio is requires a higher resolution (recommended 59,4 x 84,1 cm document size).

  • Choose your orientation (landscape or portrait).
  • Set resolution to minimum 300dpi (recommended: 600 dpi).
  • Set Color Profile to Adobe RGB (1998).
  • Select Create.
Create new document to place your image file

Placing the image

Before placing the image on your document please consider to put some white space around the image (called margins/passepartout). Many artists use white spaces around their posters as the poster can look more exclusive. If your customer put your poster in a frame, it also prevents the outermost of the sides (about 0,5 cm.) to be covered by the frame.

Suggested margin sizes:

  • A4: 1,5 – 2,5 cm.
  • A3: 2 – 3 cm.
  • A2: 2,5 – 3,5 cm.

On larger images it might be a good idea to make the bottom wider than the rest, especially if you have a text or signature in the bottom of the image.

Now place the image on the document by either:

  • Drag an image file onto the canvas, or
  • Or go to File > Place Linked to select an image from your files
If box pop up when you try to place your image file select “Assign working RGB: Adobe RGB (1998)”.
  • Adjust the size of the image by clicking and dragging the handles on the corners of the image to fill the document. Be careful not to distort your artwork.
  • It is not necessary for you to add crop marks (cutting marks) to the document. Our printer will do it automatically.

If the image file is smaller than the canvas (document) it might not be in a sufficient quality.

Once your image file is placed correctly on your canvas (document) you can make color correction changes in Photoshop if you wish. Color correction such as white balance changes in Photoshop may be necessary as the colors might have changed from the original image file when converting to Adobe RGB (1998) color profile.

Please use a good monitor to display the colors of your image correctly. If your monitor is not reflecting colors properly, the print might not look the same as on your computer monitor.

Now your image is ready to be exported.

Exporting (saving) the document

  • Go to File > Save As
  • On the file type selection, choose PDF
  • In Save Options, uncheck ‘Layers’ and set Color to Adobe RGB (1998).
  • We recommended saving it as a copy (so you keep your original .PSD file
  • Name your file
  • Click Save
  • Click Save PDF
  • Uncheck “Optimize for web” and “Perserve Photoshop Capabilities”
  • In the compression tab: Do not downsample and keep Image quality at maximum.
  • In the output tab: Choose convert to destination, Adobe RGB (1998) and include profile.

Good job! Now we will be able to open your file once submitted and print the best possible posters in the correct colors and great resolution.

If the finished file size is below 10MB, you might have done something wrong or the image file is simply not in a sufficient resolution.

Save Image: Check Embed Color Profile
Export to PDF: Uncheck all
Compression: Do not downsample
Output: Adobe RGB (1998)
