To quote www.NetLingo.com
"Resolution
"A common computing term, it refers to several things. On a computer
monitor, it is the number of pixels (horizontally) and lines (vertically) on
the screen. For printers, resolution is a measurement expressed in dpi that
describes the sharpness of a printed image. With sound boards, it is the
number of bits used to encode sounds. And in business, it describes some
form of mutual agreement."
My printer will work at the following print resolutions; draft, 360d[ots]
per inch through various steps to 2880 d[ots] per inch
Whenever I get prints done out of the house the photo lab asks for images at
no less than 300 p[ixels] per inch.
Is anyone able to provide a clear explanation of the relationship between
pixels per inch and dots per inch ?
Does an increase in pixels per inch generate an increase in dots per inch or
are the two mutally exclusive ?
If a printer's technology can only deliver a maximum or so many dots per
inch is there a formula to show that an image resolution beyond so many
pixels an inch is un-necessary ?
If this question has already been flogged to death I apologise for asking
again.
