The following instructions explain how to prepare your design(s) for electronic filing.

Technical requirements regarding image files
These instructions help to ensure that your image files comply with the technical requirements under the Hague System. Moreover, they help to preserve the quality of the publication of your reproductions.
|Image format||JPEG or TIFF|
|Minimum size||3cm x 3cm (at 300 dpi)|
|Maximum size||16cm x 16cm (at 300 dpi)|
|Maximum file size (per file)||2 Megabytes|
|Color||RGB or Grayscale|
|Borders||Between 1 and 20 pixels|
Image files with a low resolution (72 dpi or 150 dpi) will be scaled up to the minimum size of 3cm x 3cm 300 dpi. The result will be a blurry image where the details of the designs are not displayed. Images that are optimized for web, embedded in other documents or shot with smartphones are likely to have a low resolution. It is recommended to provide images with a native resolution of 300 dpi.
The resolution corresponds to the density of information of your image. 300x300 dpi means that there are 300 pixels (or points) in a surface of one inch (2,54 cm). For optimal quality, your images should be between 250x250 dpi and 300x300 dpi. Less or more than that, the system will resize automatically your images to a resolution of 266x266 dpi.
To avoid undesired scaling and loss of proportions of you different images, ensure that all your reproductions have the same resolution, ideally 300x300 dpi.
Providing image files in a resolution higher than 300x300 dpi shall not improve the quality of your publication, since the reproduction is automatically scaled down to 266x266 dpi.
It is important to keep at least one pixel of border. This will avoid loosing information when your image is cropped for publication.
Also, the image file must be trimmed to avoid having large borders. A trim between 1 and 20 pixels is suggested.
Example of too large borders. It is a bad practice for electronic E-Filing.
