Offset lithography remains the dominant printing technology for folding cartons
and high-quality corrugated packaging, delivering exceptional print quality,
consistent color, and efficient high-volume production.

**Process Fundamentals:** Offset printing transfers ink from plate to blanket
to substrate. The plate cylinder carries the image, the blanket cylinder
receives and transfers the ink, and the impression cylinder presses substrate
against the blanket. This indirect method produces smoother prints than direct
contact methods and allows flexible substrate handling.

**Sheet-Fed vs. Web-Fed:** Sheet-fed presses handle individual sheets,
excelling at folding cartons, displays, and smaller corrugated formats.
They offer quick changeover and superior register accuracy. Web-fed presses
print continuous rolls, optimizing high-volume corrugated production with
inline converting capabilities.

**Color Configuration:** Four-color process (CMYK) creates full-color images
through halftone dot overlays. Six and seven-color presses add orange, green,
and violet for expanded gamut printing that reduces spot color requirements.
Spot colors (Pantone Matching System) ensure brand color accuracy for logos and
corporate identities.

**Packaging Considerations:** Corrugated offset printing typically uses
pre-printed linerboard laminated to single face or applies top-coatings for
direct printing. Folding cartons print directly on SBS or CUK board. UV curing
systems enable immediate drying and resistance properties essential for
retail packaging.

**Quality Advantages:** Offset delivers 175+ line screen resolution with precise
dot reproduction. It handles fine text, vignettes, and complex graphics better
than flexography. Consistent ink film thickness across the sheet produces
uniform color. These advantages justify offset's higher setup costs for
premium packaging applications.
