Printing, Display & Output

The density of image pixels mapped onto a printed surface, which together with the file's pixel dimensions determines the print size.

Print size = pixels / ppi ppi

Displaying photographs by projecting light through or onto a surface, for audiences rather than individual viewing.

lumens

Printing, Display & Output

A clear spray, laminate or varnish applied over a print to guard against ultraviolet light, moisture and abrasion.

Printing, Display & Output

Monochrome printing using four or more black and grey inks, with colour inks disabled or minimised.

count

Printing, Display & Output

Software that converts an image into the precise droplet pattern a printer lays down, replacing the standard driver.

Printing, Display & Output

Choosing pixel dimensions and compression for images intended to be viewed on screens rather than printed.

px

Printing, Display & Output

The correspondence between how an image appears on a calibrated display and how it appears as a print.

Printing, Display & Output

Simulating on a calibrated screen how an image will look when printed on a specific paper and printer.

Printing, Display & Output

A halftoning method using dots of fixed size distributed in a randomised pattern rather than a regular grid.

µm

Printing, Display & Output

A small print, often of selected crops, made to evaluate colour, tone and sharpening before committing to full size.

Printing, Display & Output

An enclosure providing standardised, controlled illumination for judging prints and proofs.

K, lux

Printing, Display & Output

The distance from which a print is normally seen, which determines how much resolution and sharpening it actually needs.

Typical distance ≈ print diagonal m
