Resolution is a print-related word that describes how many dots a device can fit into a square inch of paper. The term “print resolution” refers to a horizontal and vertical measurement that is frequently represented in this way: 600 x 600 dpi.
In general, the first number indicates the quantity of horizontal dots, whereas the second indicates the quantity of vertical dots. The number of dots an inkjet printer’s print head can lay down during each pass determines the horizontal resolution, while the vertical resolution is governed by how the page is ‘stepped’ through the printer. Depending on the type of equipment and its intended use, print resolution varies greatly. Inkjet printers, in instance, may generate resolutions up to 9600 x 2400, whereas ordinary office printers often do not provide resolutions greater than 1200 x 1200dpi.
So, why the big difference in print resolution?
The main determining factor is the intended use and the target audience. A resolution of 600 x 600 or 1200 x 1200 is suitable for text and other standard office documents since it provides definition that is simple to read, especially when it would typically only be viewed at arm’s length.
On the other hand, contrasted with standard office labour, images, graphics, and artistic creations frequently receive more deeper examination. A lower print resolution would result in the individual dots being more apparent when examining photographs up close, giving the impression that the image is “grainy.” This effect is lessened at higher resolutions since it seems that the image is more solid and smooth due to the size and number of dots.
Epson’s current A3 professional photo printers have a resolution of 5760 x 1440 dpi, while Canon’s counterparts have a resolution of 4800 x 2400 dpi, making them perfect for all photographic applications. Although it may seem contradictory, A2 photographic printers and large format devices often offer somewhat lower resolutions (2400 x 1200dpi or 2880 x 1440dpi). This, too, is a result of intended usage. A2 and bigger prints are typically used for exhibition and are frequently in the form of posters or artwork. These might have a lower resolution while yet producing the same smooth and detailed image since they would be viewed at far larger distances than regular pictures.
When selecting a printer, print resolution is a crucial consideration, but the intended application should also be taken into account. Look for A2 or large format machines with 10 or 12 ink colour sets to produce huge wall-mountable prints. The finest results for photographs that be examined up close come from desktop A3+ professional photo devices, which have outstanding resolution and huge colour sets of ink for optimum vibrancy. A4 machines may generate decent quality album-sized photos.
