How to stop colours fading when you print a PDF

7 min read

A screen makes colour with light. Paper reflects it. That gap explains most of the “my colours faded in the print” problems, and it means some of the loss is built in. What you can control is how much of it you lose: the colour mode of the file, the export settings, the paper and the printer settings.

Why print looks duller than the screen

  • Screens mix red, green and blue light, and can show very saturated colours, including bright neon-like shades. Printers mix cyan, magenta, yellow and black ink, which cannot reach the same range.
  • A backlit screen is brighter than any paper. A page that looks vivid on a phone looks flatter against the white of a sheet.
  • Uncoated plain paper absorbs ink and spreads it slightly, so colours look softer than on glossy photo paper.
  • Low ink levels or draft mode make every colour weaker.

Export settings that help

  1. Export or save as PDF at the highest quality setting rather than a small-file or web setting, which compresses images harder.
  2. Keep images at around 300 pixels per inch at their printed size. Much lower looks soft and washed out.
  3. Embed fonts, which most programs do by default, so text does not change on another computer.
  4. If a print shop asked for a specific colour profile or standard, follow that. For a home printer, the default is usually correct.

Printer settings that matter

  • Let one side manage the colour. Most home printers do a decent job when the printer manages colour, and doing it in both the app and the driver can double-correct.
  • Choose the paper type that matches the sheet. A photo paper setting on plain paper floods it with ink, and the opposite starves a glossy sheet.
  • Pick the higher quality level for pages where colour matters, and turn off economy modes.
  • Compare against a test page. Print one page, compare it with the screen, and adjust once at a time.

When the colours are pale in the file

Light yellows, pale blues and pastel fills are weak on screen and can vanish on paper. If you cannot change them at the source, darken the page a little with Darken a PDF for printing. Keep colour stays on by default, so colours are strengthened rather than turned grey.

Be realistic about the limits. The tool adjusts tones, but it does not convert between colour systems or match a printer profile, and it cannot add saturation that the printer cannot reproduce. For colour-critical work, talk to the print shop.

If you only need it legible

For forms, receipts and reports, colour is often decoration. Grayscale PDF shows how the page will look in mono, and a single-colour print of a faint page is usually clearer than a colour print of the same page on low ink.

Questions

How do I export a PDF so the colours do not fade in print?

Export at high quality, keep images at about 300 PPI, and let either the app or the printer manage colour, not both. Then print one test page and compare it against the screen before printing the rest.

How can I print a PDF without losing the colour of the digital file?

You cannot match a backlit screen exactly, because printers have a narrower colour range. You can get close with the right paper type, quality setting and ink levels.

Does this tool change colours?

It adjusts tone and, with Keep colour on, preserves the colour of stamps and signatures. It does not convert colour systems or match printer profiles.
