In order to customise the bleams and covers, placing one or several images can be ideal. However, some recommendations are to be taken into account.

Recommended formats

The conventionally Chrome compatible formats are encouraged:

• JPEG in RGB
• GIF
• PNG

About the weight :

• Less than 1Mo per image, for better performances

About the dimensions :

• Bleams' logo:
  • From about 100x100. The larger the printed/engraved bleam, the wider the logo
  • No obligation to use square images
•  Buttons:
  • From about 100x100
  • No obligation to use square images
• Covers:
  • 800x800 optimal
  • The image must be a square

Formats to avoid

The uncommun or old formats involve some incompatibility risks:

• JPEG in CMYK
• PNG in 16 bits
• WebP
• BMP
• TGA
• PCX

About the weight:

• Beyond 1Mo per image, the performances may decrease

About the dimensions:

• An image wider than its use may lower its performance
  • Example : A 4000px wide image in a 800px wide rendered cover might be uselessly long to load & display
• An image smaller than its use may lower its visual quality (pixelated image)
  • Exemple : An 300px wide image used a 800px wide rendered cover might have a low quality aspect

Additional note

• Square shaped pictures are not mandatory
• The TIF format images :
  • Are not read on Android. The Android default image reader is not able to read .tif.
  • Are read by iOS. The iOS default image reader is able to read .tif.
