Resolution/Bitmap/Raster

What resolution is best for reproduction?

Why do some printed images show "pixelation"?

RESOLUTION

Often, images are referred to as high resolution (hi-res) or low resolution (low-res). High resolution would be an image intended for print, generally having 300 samples per inch or more. Low resolution refers to images only intended for screen display, generally having 100 pixels per inch or less. Images from the internet are usually only 72 dpi so they'll lack the quality needed for print. Please submit your files at a minimum of 100 dpi at actual size . We can accept files with a higher resolution (250-300) for better printing results. Please contact us for further guidance if you have any questions.

BITMAP ARTWORK

A bitmap is a type of graphic composed of pixels (picture element) in a grid. Each pixel or "bit" contains color information for the image. Bitmap graphics formats have a fixed resolution which means that resizing a bitmap graphic can result in distortion and jagged edges.

Photo-editors or image-editing graphics software such as Adobe Photoshop and Corel Photo-Paint are designed for creating and editing bitmap graphics
