Poor reproduction of small point sizes, fine-line work, Color corrections can be isolated to one image, Cost of engraving and changing cylinders is high ($10,000-$15,000), making versioning expensive, Precision registration of inks achieved quicker, Color changes possible only across whole width of web, Few closed-loop color-matching systems available, Fewer vendors to choose from, although more are expected to come to the market soon, Plates are cheap and easy to make, which allows for versioning, Larger books must be printed as a number of forms, Handles fine line work and thin edges well, Several offset vendors using cutting-edge closed-loop color-matching systems, Aligning ink colors is challenging; more tradeoffs required to match colors, More vendors with high-speed, large-format offset presses from which to choose, More tension means you must print on heavier paper stock, Requires additional plates for longer runs.
