    Resolution

    • Image resolution must be 72 ppi (pixels per inch) or 28.346 ppc (pixels per centimetre) at 100% of final format.
    • For optimal display, the images can be delivered in Retina format, i.e. at 200% of the final format.
  • 1.2

    Formats

    • Four image file formats are accepted: GIF, PNG JPG and SVG.

      Generally, PNG is best for transparency, GIF for solid colours, JPG for images and photos and SVG for vector graphics.

    • Animated GIF formats are accepted. Note that animations must not start automatically; they must be reader-triggered. When a GIF-format ad first loads, it must be static.
  • 1.3

    Colour

    • When exporting your images or photos, please do not include the colour profile. It increases the file size and is incompatible with the code used for digital tablets.
    • Use RGB colour mode at 8-bit depth.
    • Use colour space: Adobe RGB 1998.
    • For optimized image file size, use “Save For Web and Devices”.

    • The content of the video must be in French. If the audio is English, French subtitles must be provided.
    • The video will play in an HTML5 player (any custom video players will be ignored).
    • We recommend a maximum of 3 videos per ad, each with a maximum running time of 3 minutes.
    • Total video files uploaded to our FTP site for one ad must not exceed 500 Mb.
    • The video player must always provide access to controls to pause/stop the video or enter full-screen mode.

      Code permitted

    • In the tablet version of La Presse+, when the reader activates an ad containing video, the video plays within the ad surface area and is not enlarged unless the reader touches the button triggering full-screen mode.
    • If the playback trigger button is positioned inside a box graphically demarcated from the rest of the ad (e.g., representing a screen, TV, tablet), the video must start playing in that box, with the reader then given the option of entering full-screen mode.
    • Video playback is in streaming mode; the video file is not part of the ad file. Playback is therefore unavailable in offline mode.
    • Your material will be hosted on a multimedia server managed by La Presse.

    • The maximum number of audio files per ad is 3.
    • Audio clips shorter than 5 seconds that play when another interaction is triggered must be accompanied by an audio icon Audio Audio , at about 30% opacity.
    • Because La Presse+ is made available on multiple tablet OS’s, it is unfortunately impossible to perfectly synchronize playback of short audio files with a specific reader action.
    • The maximum run time of audio files is 2 minutes.
    • The audio player must always provide access to controls to pause/stop the audio clip.
    • You can customize the trigger for starting/stopping playback of your audio using graphical elements such as “Play” and “Stop” buttons. If you do this, we recommend masking the default HTML5 player display='none' and using these methods:

      Start audio clip:
      document.getElementById('audio').play();
      Stop audio clip:
      document.getElementById('audio').pause();
    • If the audio file size exceeds 50 Kb, your material will be hosted on a multimedia server managed by La Presse, and the audio will not play if the tablet has no Internet connection.
    • Audio playback is in streaming mode; the audio is not part of the ad file. Playback is therefore unavailable in offline mode.
