Images and colour

Images and colour

Image resolution depends on print size. Colour on a screen also differs from colour printed on paper.

Enlarging a small image does not add detail

When the same number of pixels is spread over a larger area, individual pixels become visible. Use the original image instead of a screenshot or a copy reduced by a messaging app.

Enough pixelsDetails and edges stay clear.
Too few pixelsThe enlarged image looks blocky.

An enlarged comparison of the same image. Changing the file's ppi setting alone does not add image detail.

Is your image large enough?

Find the image width in pixels in the file properties, then try your planned print width.

305 ppi

Meets the approximate 300 ppi target for small print products.

300 ppi is a common target for products such as cards and brochures. For large-format prints, the appropriate resolution also depends on the product and viewing distance. Ppi describes image resolution; dpi describes printer dots.

Screens and paper produce colour differently

RGB · screen lightRed, green and blue light. A bright screen can show colours more vividly than print.
CMYK · printing coloursCyan, magenta, yellow and black. The paper and printing method affect the result.

Do not convert colour mode just in case

aDigi can work with good-quality RGB and correctly prepared CMYK artwork. If you are unsure which colour profile to use, ask before converting. The brightest screen colours may look more subdued in print.
