Document Resolutions
Understanding the inner workings of printers and how exactly they are able to churn out quality results is important for consumers to know before purchasing a new model. For information on image resolutions you can look at Wikipedia. One of the main elements that contributes to a printer turning out high resolution results is the dpi, or dots per inch produced by printer ink cartridges. An image’s dpi, specifically, is the number of individual dots of ink that can be placed in a line within 1 inch of space.
Dpi is also characterized as the increase in size of the halftone dots on hard copy prints during printing. This effect is caused by the spreading of printer ink across the surface of paper. Most often, the dpi measurement is consequential of the specific model used, print head technology and the driver settings. Typically, models that produce higher dpis turn out projects that have more sharp and detailed resolutions than models with low dpis.
A common inkjet printer prints ink through small nozzles and produces an average resolution range of 300-600 dpi. Laser printers, however, spray toner through a controlled electrostatic charge and are able to print a maximum high resolution of 1800 dpi. Typical models implement cyan, magenta, yellow and black ink in their print head technology. The greater variety of color ink used allows printers to create a dpi with a better fixed volume of ink in each dot.
However, most printers only print with a 4 or 5-color ink system and must therefore print additional color by way of a halftones. Consumers looking for printers that can produce the best quality resolutions should consider dpi capabilities and the number of color ink used for printing. Also remember to research other contributing factors like the type of print head technology used and the adjustment settings for drivers.
