How Is Printer Resolution Measured [Picture Quality Improver]

In printing pictures, print resolution is the eventual aspect that determines the extent your photo snaps when you have a hard copy from a digital device. Simply the printer resolution figures out the legibility of the text. It determines how detailed the image is and how well it is visible. The resolution of printing proportional to the quality of the print, the higher the resolution the sharper is the image.

In printing documents, images, and photos, the resolution is of prime importance as quality image gives a professional look to your output. A low-resolution print is fuzzy and unattractive and often loses the interest of the reader. Let us see how a printer resolution is measured.

 What Is A Resolution In Printing?

Resolution in printing measures the number of dots a device is able to imprint in 1 sq. an inch of space on a page. The prints are comprised of dots. The resolution is expressed as dots per inch or dpi in vertical and horizontal positions. A figure of 300 dpi is a norm for achieving an output of high resolution. The range of high-resolution printing is between 300×300 dpi to 90,000 dpi.

How is Printer Resolution Measured

Depending on the printer, the print resolution varies. The difference in the printer’s resolution is because of the intended printing output. For printing text and easy-to-read documents, the resolution would be 600×600 or 1200×1200. For images, higher resolution creates detailed visibility. The low resolution produces less fineness of color, fuzzy, blurred, and unprofessional picture.

 What Is Dots Per Inch?

The printer resolution or dpi is the number of dots of ink a printer can imprint on an inch of paper. The term differs from pixels per inch or PPI, which means the number of pixels digitally displayed on the screen of the computer. Although both imply the quality of the print, the terms are similar but not the same.

dot per inch

In measuring the print resolution by counting the dots per inch printed from the inkjet printer, it refers to the lines per inch both horizontally and vertically. In the formation of graphics and text, dpi specifies the density of the dots capable of printing in an inch. The resolution of the print can be different on the two axes. The dpi that runs with the travel direction of the inkjet printer remains fixed. In such a situation dpi denotes the nozzle number per inch in the print head, which prints the picture. Thus, dpi maybe 600×600 or 600×1200 in different outputs. A more number of dots in an inch (DPI) means a sharp image. Logically thinking, the higher resolution has high quantity and size of dots creates illusion to make the image look smooth and solid with better visibility. To achieve a good print, choose a high-resolution inkjet printer.

 High-Resolution Images vs. High-Resolution Printers

 The resolution of an image refers to the number of pixels displayed per inch on an image. Pixels are a small area of light rays on the display screen. As the unit of measure is per inch, the expression is pixels per inch or PPI. The higher resolution of the image means a higher PPI, with simultaneous crispier and quality picture.

 The high print resolution means more detail of the image in the printout. As indicated, it is expressed as DPI, here again, high numbers denote quality picture.

 The relative figures of PPI to DPI for quality images is that a high-resolution image must have 300 DPI print resolution and a PPI of 5000 x4 000pixels. To clarify the point, an image of 640 x 40 PPI at 72 DPI, that image is tiny. You may often find ‘blown up’ images because of printing low pixel images.

Printers with high-resolution images and printing are available both in inkjet and laser technology. The inkject computer printer resolution of 300 to 720 DPI has mini nozzles and creates detailed prints. In laser printers, resolution comes with 2400 dpi for graphics and 300-600 for texts, which produce beautiful prints.

 Importance of Choosing the Correct Resolution for Printing

 All printers have a range of DPI, so you have to choose yours from experience. Remember that 300 x 300 dpi has 90,000 dots per inch, which is high enough to create quality prints. Almost all experts in the printing world recommend a printing resolution of 300DPI. A lower DPI will not produce a quality picture.

 Final Words

After going through this article, you can see that printing quality images and text are not difficult. With all the modern specifications available in modern inkjet and laser printers, all you need to do set up the printer and order your job. The text has some of the ways of on how printer resolution is measured to your advantage.

However, the graphic or the photograph you want to print must be of good quality. This means that you have to adjust the resolutions from the start of graphic designing or snapping the photographs. Besides the printing paper matters. An inkjet printer paper will not be the best for laser printers. The resolution of the printer may need to change depending on the size of the print. Posters, flyers, documents, cards, and brochures may not create the best prints with the same resolution as a printer. However, to start with as many suggested using the golden DPI of 300 may be a wise decision.
