At Bibliomanager, we connect your catalog of 100.000 titles<\/strong> to readers worldwide. But in a global \"sell first, print later\" ecosystem, technical precision is everything. A faulty ISBN or an unreadable barcode<\/strong>doesn't just cause a delay\u2014it triggers an automatic rejection from logistics systems and retailers.

5 common mistakes that kill sales<\/strong><\/p>\n\n\n\n

    \n
  1. \"Muddy\" Blacks: <\/strong>Never use a four-color mix for barcodes. If it\u2019s not 100% Carbon Black (K:100)<\/strong>, laser scanners at major retailers won't catch it.<\/li>\n\n\n\n
  2. The mismatch:<\/strong> Ensure the ISBN on your barcode perfectly matches your metadata and your copyright page.<\/li>\n\n\n\n
  3. Platform-Specific IDs: <\/strong>ASINs or other proprietary IDs from specific platforms are not valid in the traditional global bookstore network.<\/li>\n\n\n\n
  4. Missing barcodes:<\/strong> High-volume retailers require a physical barcode on the back cover for automated intake.<\/li>\n\n\n\n
  5. Multi-volume errors:<\/strong> Remember, each individual volume in a set requires its own unique ISBN.<\/li>\n<\/ol>\n\n\n\n

    Your pre-flight checklist<\/strong><\/p>\n\n\n\n

      \n
    • Color:<\/strong> Use C:0% M:0% Y:0% K:100%.<\/strong><\/li>\n\n\n\n
    • Background: <\/strong>Keep it white or very light; high contrast is non-negotiable.<\/li>\n\n\n\n
    • Resolution:<\/strong> Minimum 300 dpi<\/strong>.<\/li>\n\n\n\n
    • Dimensions: <\/strong>Standard 1.375\" x 1.0\" (approx. 3.5cm x 2.5cm).<\/li>\n\n\n\n
    • Placement: <\/strong>Must be clearly visible on both the copyright page and the back cover.<\/li>\n<\/ul>\n\n\n\n

      \ud83d\udca1 Tip Bibliomanager:<\/strong> Try the \"smartphone test.\" Scan your back cover with any barcode app. If your phone struggles to read it, a bookstore\u2019s industrial scanner definitely will.
