What is DPI ?
Many people are confused as to what these 3 letters mean and more importantly, how they determine the print quality of their digital images. Basically, DPI stands for Dots Per Inch. When people use the term they are referring to the resolution quality of an image. More dot’s equals better resolution, meaning your image is sharper and you can see more details. Increase DPI printing on metal and acrylic according to how sharp you want your image to appear. We will discuss how to achieve the best results for dpi printing on metal and acrylic .
We all want our images to come out looking amazing, but many of us are confused as to how to set the image’s resolution.
The Difference Between DPI & PPI
The resolution of a digital photo is its pixels. DPI is a bit of a misnomer for what it actually does. For example, a photo that is 300 DPI is really 300 PPI, which stands for Pixels Per Inch. DPI was used when a digital image was printed to a printer and read as 1 pixel = 1 dot. But technology has advanced and so this formula is not applicable to modern printers that use a blended dot and remap your image to convert it into print.
Even though the technology has changed you will still find a DPI or PPI setting within most digital photo software. Print materials are prepared using DPI. For better print quality the DPI the value should be 300 or more.
How to get a High Resolution Photo
The resolution of an image refers to the dots of ink or electronic pixels that make up a picture. It’s important to begin with a high-quality image which means the highest resolution and image dimensions you can get. When it comes to source images, bigger is better, because you can go down in size, but not up, without losing quality.
The resolution of most monitors is 72 PPI – the size almost all digital files will be displayed as when downloaded. In order to ensure a high quality print, you must adjust the image quality before you send to your printer. You won’t see the change on your monitor in terms of quality but you will see the size reduction in the print. The improved quality will come in the printing.
DPI Printing on Metal metal and Acrylic
150 0r 300 DPI printing on metal and acrylic is recommended. Unless you are shooting raw, 300 DPI would be hard to obtain. Always strive for between 100-150 DPI. Since this is technical, we often have customers send us their photo through the free consultation section of the site so we can guide them.
If you are unsure of the DPI size of your photo it’s simple to see:
- Right click your image
- on the bottom click properties
- click details on top of page
- 7 rows down you will see the DPI size of photo
If you wish to see the size you can print at using the same photo
- right click your image
- on the bottom click properties
- click details on the top page
- just above the DPI there is pixel width and height dimension
- divide the width and height dimension by the DPI you wish to print at
If the pixel dimension is 3000 by 4000 you would be able to print an acrylic at 20-26.6 inches at 150 DPI
