PNGs are one of the most commonly used file types. They are perfect for some situations but not so much in others. Lets talk about why!
Over here at FM we prefer to use .pdf files so whenever possible use that file type, but here is some info about the widely used .png file type. if you end up needing to use it.
What is a PNG?
A PNG, or Portable Network Graphics, is a popular image file format that is commonly used for web graphics and digital photography. It supports transparent backgrounds and lossless compression, making it ideal for images with sharp edges and text. PNG files are probably one of the most widely used file types in modern day next to .pdf files and .jpg files.
What are the benefits of using a PNG file?
PNGs are mostly appreciated for supporting transparent backgrounds. This makes them great for setting up quick proofs or layering in image files. They are also easy to save and send due to their widespread use and support across many sites and platforms.
What are some setbacks of using PNG files?
Color Modes
PNG files cannot be saved out in CMYK color mode. PNG files only support RGB color mode which is made for digital screens and not print media. This means that if you have an art file in CMYK color mode and save out as a .png it will automatically be converted to RGB color mode and can result in a shift in color. Since PNG files only support colors for digital screens they can also display colors that are much brighter than can be printed via a CMYK printing process with physical inks. A PNG file will work well enough for a spot color (1, 2 or 3 color) printed image
Resolution
Since PNG files are most widely used for web display many programs default or quick export settings only export at 72 DPI. 72DPI or pixels per inch will result in a clear display on computers but might look pixelated or jagged when printed. Print media should be saved at 300DPI. Generally you want to setup and save your file at 300 DPI and "save as" or "export as" .png as high quality instead of a quick export. This should maintain the size and quality of the file. If your file is still appearing double the size and or low resolution you may want to save as a .pdf instead.
With PNG files getting use pretty much everywhere these days it can be confusing to try and prep a print ready file, but we hope this article added some clarity as to when and where PNG files are suitable.
