Free Printable Test Sheet

RGB Printer Test Page

Print this free RGB printer test page to compare the colors on your screen with the colors your printer produces. The sheet contains pure red, green and blue blocks, RGB gradients, blending tests and brightness and contrast blocks.

How to Use This RGB Test Page

The RGB test page is a screen-to-print comparison tool. It shows how faithfully your printer reproduces the colors you see on your monitor.

View the page on screen

Look at the blocks and gradients on your display first — this is your reference.

Print in color

Click the print button with color mode enabled and normal or better quality selected.

Compare side by side

Hold the printed sheet next to your screen under neutral lighting (daylight is best).

Judge hue, not vividness

Printed colors will be slightly less vivid — that's normal. What matters is whether the hues are correct.

What to Check After Printing

  • Correct hues: red should print red (not orange or pink), green should stay green, blue should not drift purple. Wrong hues signal a weak CMYK channel.
  • Smooth gradients: the black-to-color strips reveal banding and posterization — both signs of nozzle or quality-setting problems.
  • Accurate blends: yellow, cyan and magenta blend blocks confirm how RGB values translate to your printer's inks.
  • Distinct brightness steps: if the 80% and 100% red blocks look identical, your printer is crushing bright tones.
  • Readable contrast text: fuzzy text on colored backgrounds points to alignment or bleed problems.
  • Full hue wheel: the rainbow strip should move through every color without dull dead zones.

Why Screen Colors and Printed Colors Differ

Monitors create color by emitting red, green and blue light, and can display extremely saturated colors by driving those channels to full power. Printers work the opposite way: inks absorb light, and the paper reflects what remains. This subtractive process (CMYK) covers a smaller color range than a backlit screen, so a perfectly healthy printer will still render neon greens and electric blues a little duller than your monitor shows them.

This RGB test page helps you separate that normal limitation from genuine printer faults. Slightly reduced vividness across the whole sheet is expected; a blue block printing purple, a gradient full of bands or a blend block with the wrong hue is not. If you suspect a specific ink channel, confirm it with the CMYK test page, which tests each ink in isolation, or run the complete color printer test page for a broader check.
