Digital Printing and Emerging Technologies

Digital Printing and Emerging Technologies tests non-plate processes, short-run economics, variable data and new applications.

What the exam tests

Expect the steps of electrophotography, inkjet types and the meaning of print-on-demand.

Core rules

  • Electrophotography (laser/toner): charge a photoconductor, expose with a laser or LED to form a latent image, develop with charged toner, transfer to paper, fuse with heat and pressure, then clean and recharge.
  • Inkjet: continuous inkjet deflects a continuous stream of charged drops; drop-on-demand fires drops only where needed. Thermal inkjet boils a bubble to eject ink; piezo inkjet deforms a crystal. UV inkjet cures with a lamp; latex ink uses heat to coalesce polymer particles.
  • Digital has no plate, so make-ready is minimal and the first copy can be economical; unit cost falls slowly with quantity, unlike offset where plate cost is spread over a long run.
  • Variable data printing changes text, images or codes copy to copy; it enables personalisation, serialised labels and transactional documents.
  • Print-on-demand holds no stock and prints to order; wide-format prints banners, signage and vehicle wraps; hybrid presses combine offset or flexo with digital units.
  • Emerging areas include 3D printing (additive manufacturing), printed electronics, QR codes and smart packaging with NFC tags.

Worked example

A client needs 300 personalised certificates. Offset would need plates and separate overprinting for each name; digital can RIP a data file with 300 records and print each sheet with different text in one pass. At 300 copies, digital’s low make-ready outweighs its higher click cost. At 30,000 identical copies, offset’s lower unit cost wins. Reasoning: compare total cost, not unit price; break-even is where fixed offset make-ready equals digital’s higher variable cost.

Traps

Saying digital printing uses plates; confusing toner fusing with ink drying; assuming digital is always cheaper; forgetting that substrate and coating must be compatible with fuser temperature or UV cure.
