In a printed image the more dots, the higher quality the printed piece is. DPI is used in the printing process, and it describes the number of dots a printed document has per inch. They are confusing because they have been used interchangeably, but they are not the same.ĭPI – Dots Per Inch. If you find an image on an internet image search, it is likely a low resolution raster file.ĭPI and PPI are two terms that are used to reference raster graphic resolution. If you’re not sure of your file’s pixel dimension, look at the file size, measured in kilobytes (KB) or megabytes (MB). Generally speaking, if a file is measured in KB, it’s low-res if it’s 5 MB or more, it’s high-res. A 480 x 270 pixel graphic is lower resolution than a 1920 x 1080 pixel graphic. Resolution is measured by pixel dimension-the number of pixels that makeup the width and height of an image. The more pixels an image contains, the more detail that is captured-and the higher its resolution likewise, fewer pixels capture less detail and result in lower-resolution images. The amount of pixels in an image determines its resolution.
You may also hear them referred to as a "bitmap". When zoomed out, this tightly woven grid creates a photograph or image. Each square represents a different color or lightness. Raster graphics are made up of numerous of tiny squares called pixels. To understand why, we need to explore raster graphics.
PNG VECTOR OR RASTER PDF
pdf files are automatically vector-based. They are created and edited in computer programs such as Adobe Illustrator and, Corel Draw.
Outside of screenprinting, Vector graphics are used in text, logos, illustrations, symbols, infographics, charts, and graphs.
