Generating print-ready (PDF/X) output with iText 7
The impetus for this post is simple: I recently used an online printing service to place an order for paper cards to announce the birth of our newborn son. Since I planned to put together the card design using iText anyhow, I figured I might as well submit in PDF/X. After all, I would’ve been charged extra if the printing company had to fix my files!

“Make invalid states unrepresentable” is an oft-repeated adage in software design, particularly popular in languages with expressive type systems. It’s good advice, and it generally leads to cleaner code bases with fewer opportunities for bugs to creep in.
