Design one hierarchy, not two competitors
Decide which information must be found first, then give Arabic and English comparable authority without forcing identical line breaks. A literal mirror often creates awkward whitespace and unequal density.
Test real names, long titles, prices and addresses early. Placeholder copy hides the cases most likely to break the grid.
Check fonts after export
Confirm the licence allows print output and supplier use. Embed fonts in the production PDF or outline only when necessary and after a searchable, editable master is safely retained.
Inspect joins, diacritics, ligatures and punctuation in the exported PDF at high zoom. A correct source file can still fail through substitution or an unsupported export path.
Make numbers and punctuation intentional
Agree whether the project uses Arabic-Indic or Western numerals, then apply the decision consistently. Telephone numbers, URLs, dates and mixed-language product codes need manual review.
Do not trust automatic bidirectional behaviour for price lines, brackets, slashes or strings containing Latin model names.
Prototype every fold and panel
Reading direction changes how a booklet opens and how a folded piece is encountered. Print a reduced mock-up, fold it and mark front, back, inside and panel order.
For cartons, rotate the flat artwork and inspect every panel in the assembled orientation. Regulatory and product information should never be assumed from the dieline alone.
Run a bilingual preflight
The final check should cover fonts, black builds, overprint, image resolution, bleeds, quiet zones, finish layers and content sequence in both languages. Ask a native reader to review the final production PDF, not only the source document.
