There are many instances where you may need to enlarge an image, be it a web image that you need to print for a project or a low quality digital photograph that you would like printed onto canvas or photographic paper for display purposes. There are many problems that are encountered while trying to enlarge an image. I’ll explain some of them here, as well as an explanation of the key terms that you need to understand before enlarging an image.
DPI (or dots per inch) is a measurement that is used to show either:
- The amount of individual dots that make up 1 inch of an image. This measurement shows the total amount of dots that make up 1 inch of an image when displayed on screen. Most images found on the Internet today are displayed at 72 DPI. The minimum DPI necessary to produce a good quality print is around 150 DPI. This is where problems start when it comes to printing these images. Always check the DPI of the image you wish to print using photo editing software to ensure that the DPI is over 150. Any lower than this will result in poor image quality when printed.
- The amount of individual dots of the ink used to print 1 inch of an image. This measurement shows us how many droplets of ink are used to make up 1 inch of an image when printed. This measurement is very important when it comes to printing a photo on canvas or other media. Regardless of the resolution or DPI of an image, if the printing equipment being used does not prints at a high level of DPI, (at least 300 DPI) then even the greatest quality image will appear blurry with a huge loss of detail and clarity. Always check that the company you choose to print your photo on canvas or photographic paper will be printing your image at the least 300 DPI.
Pixelation is a problem that is caused by increasing the size of a bitmap (an image made up by pixels such as JPEG files) to such a degree that the individual pixels become visible to the naked eye. There are ways to reduce pixelation using modern photo editing software such as Photoshop. There are methods that can be used to minimize the impact of pixelation.
The resolution of an image is the amount of individual pixels that put together that image. The higher the amount of pixels, the less each pixel is stretched when the image is enlarged. The resolution of an image is the most important factor when thinking about enlarging an image. The higher the resolution of the image, the less pixelation that will occur and the better the image quality will be when printed.
So what is the best way to reduce pixelation when printing an image?
When you’re thinking of printing a digital photograph on a larger scale, whether ordering a photo on canvas or printing an image onto photographic paper yourself for display purposes, the best way to avoid pixelation altogether is to select an image that is high in resolution. With digital cameras now commonly available, taking photographs at a minimum of 5 megapixels, taking high-quality photos that can be transferred onto canvas is now even easier. If you have no choice but to use a poor quality photograph, always speak to a professional first to see what kind of result you can expect to see when your image is printed at a large scale. Many photo on canvas sellers specialize in editing and enlarging photographs and they will inform you of any issues before sending your photo to print.
Canvas prints are by far the best choice when printing images at a large scale. Even at low resolution, photographs can remain crisp and clear when printed onto canvas.
