Printing - Comparison of Printing Methods

Comparison of printing methods
printing process transfer method pressure applied drop size dynamic viscosity thickness of ink on substrate notes cost-effective run length
Offset printing rollers 1 MPa 40–100 Pa·s 0.5–1.5 µm high print quality >5,000 (A3 trim size, sheet-fed)

>30,000 (A3 trim size, web-fed)

Rotogravure rollers 3 MPa 0.05–0.2 Pa·s 0.8–8 µm thick ink layers possible,
excellent image reproduction,
edges of letters and lines are jagged
>500,000
Flexography rollers 0.3 MPa 0.05–0.5 Pa·s 0.8–2.5 µm high quality (now HD)
Letterpress printing platen 10 MPa 50–150 Pa·s 0.5–1.5 µm slow drying
Screen-printing pressing ink through holes in screen <12 µm versatile method,
low quality
Electrophotography electrostatics 5–10 µm thick ink
Inkjet printer thermal 5–30 pl 1–5 Pa·s <0.5 µm special paper required to reduce bleeding <350 (A3 trim size)
Inkjet printer piezoelectric 4–30 pl 5–20 Pa·s <0.5 µm special paper required to reduce bleeding <350 (A3 trim size)
Inkjet printer continuous 5–100 pl 1–5 Pa·s <0.5 µm special paper required to reduce bleeding <350 (A3 trim size)

Famous quotes containing the words comparison of, comparison, printing and/or methods:

    But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.
    Ralph Waldo Emerson (1803–1882)

    Intolerance respecting other people’s religion is toleration itself in comparison with intolerance respecting other people’s art.
    Wallace Stevens (1879–1955)

    Before printing was discovered, a century was equal to a thousand years.
    Henry David Thoreau (1817–1862)

    If men got pregnant, there would be safe, reliable methods of birth control. They’d be inexpensive, too.
    Anna Quindlen (b. 1952)
