How to Make a High Quality Print of Digital Art

The size and resolution of an image affects both its appearance on your reckoner screen and its print quality.

Resolution

Resolution refers to the amount of visual item contained in an image. The resolution of output devices (printers) is measured in dots per inch (dpi), and in the example of halftones, lines per inch (lpi).

An instance of a high-resolution (left) and low-resolution (right) epitome. In press terms, a higher dpi means that the printer will identify more dots of ink for every inch of artwork.

• For most artwork, 300 dpi is preferred. Well-nigh printers produce fantabulous output from images set at 300 ppi.
• You can use 150 dpi for large prints because the deviation in impress quality is not very noticeable on large pieces when you look at the prints from a distance.
• Output device resolutions vary, depending on the type of press and paper used. In general, a photograph is output at a crisp 150 lpi if printed on glossy magazine stock, and at 85 lpi if printed on newspaper stock.

Sheet dimensions

The sail dimensions make up one's mind the size of your artwork when it is printed. When you set the sail size, cull options that correspond to the epitome's destination.

• Consider the largest size at which y'all plan to impress your artwork, as well as any smaller or larger copies that you may need.
• Choose a larger prototype size to preserve more than image detail. The large size makes it easier to maintain image quality when you demand to produce a smaller version of the image. For example, you lot tin can ready the resolution of a new image at 300 pixels-per-inch (ppi), the width to 16 inches, and the summit to 24 inches.

Starting with a standard frame size, for example, xviii in by 24 in, will give y'all an adequate corporeality of detail. When you lot create a new certificate, outset set the resolution, and then specify the width and the height.

It is always better to first with a bigger canvas because y'all tin subtract the width and height of your image at any point without affecting its quality. Nevertheless, when you increment image dimensions, the application inserts new pixels between existing pixels, and their colors are based on the colors of adjacent pixels. If you increase image dimensions significantly, images may announced stretched and pixelated.

Changing the height and width of an image without irresolute the resolution results in quality loss. Left to right: paradigm with smaller dimensions, original image, prototype with larger dimensions.

• When choosing a canvas size, make sure your document has the proper aspect ratio that will allow you to print to mutual canvas and paper sizes (for example, 8 in past x in, eleven in by 14 in, 16 in by xx in, 18 in by 24 in, etc.) without cropping your artwork.
• If you are using a personal laser or inkjet printer, fix your certificate size in inches, centimeters, points, or picas at the dots-per-inch setting specific to your printer.
• If you are using a commercial printer or a more than sophisticated output device, the dimensions of the paradigm should always be set up to the actual size that you want the paradigm to appear in the printed piece. A good dominion of thumb is to set the number of pixels-per-inch to twice the desired lines per inch. So, at 150 lpi, the setting should be twice that, or 300 ppi; at 85 lpi, the setting should be 170 ppi. If you have questions well-nigh the resolution of specific output devices, it'south a good thought to check with the print service provider.

Annotation that the bigger the sail size and resolution, the more pixels in that location are in a brushstroke, and the harder it may become for your estimator to process it. To ensure optimal brush and application operation, experiment to find the largest canvass dimensions that work all-time for your painting and for your software and hardware configuration.
