Printing in two colours is a tricky business. You print the dark ink
first, then the lighter ink, but making the image very slightly larger than necessary so
it overlaps the darker colour underneath. That way you avoid leaving a narrow white gap if
the paper isn't positioned quite right. This technique is called "trapping".
(Remember: you read it hear first.)
The Israeli airline hasn't quite mastered this yet: the green and blue on this
bag overlap by a full 1.5 millimetres, leaving a nasty brownish border around the green.
Plus, the small, white letters are so light, they are almost illegible. "Not to be
used for disposal of liquids and cigarette butts", they say in Hebrew, English,
French and Russian. How are passengers supposed to know this if they can't read it? Oh,
and what do you do if your barf is more liquid than solid?
