Printing performance
When printing performance refers to the number of printed paper sheets, the filling of a color printer can be achieved. The Dr. Grauert letter is often used as a reference .
The stipulation here is the so-called degree of coverage , which is around 2.8% in the case of Dr. Grauert letters. The maximum printable area of a complete paint application of 100% is rated as 100%. In practice, most manufacturers specify the number of A4 pages with a coverage of 5%, which corresponds to a normal business letter with a logo .
The typical ranges with 5% ink coverage:
- Inkjet printer : between 250 and 450 pages
- normal laser printer (single component toner): between 1500 and 40,000 pages
- high-quality laser printing systems (two-component toner): between 5000 and 72000 pages
The printing performance of the individual systems varies greatly and, particularly in the case of ink-based systems, also depends on the output medium.
With photo printing, the degree of coverage is considerably higher, depending on the image. For a landscape photo in A4 format, with a blue sky, a forest in the background and a few houses in the foreground, the degrees of coverage are around 40% for yellow, 30% for magenta , 28% for cyan and 20% for black. Usually yellow is the color with the highest consumption.
Possible ranges in photo printing in the highest quality until the first color is exhausted:
- Inkjet printer: 25-40 pages (on special paper)
- Color laser printer: 100–250 pages
- Full color systems: up to 5000 pages
