RGB Printer Test Page

Evaluate your printer’s RGB color rendering with full-saturation color bars, gradient strips, a color wheel approximation, and mixed color blocks. Ideal for checking how your printer translates screen colors to print.

How to Print This Test Page

Load high-quality white paper or photo paper and click Print This Page. Select the highest quality setting available — RGB gradients are the first place where reduced print quality becomes visible as banding. For the most meaningful comparison, use the same paper stock you’ll use for your actual prints, since paper coating dramatically affects how RGB colors translate to print.

The Screen-to-Print Conversion Chain

When you print an RGB image, your file never arrives at the printhead as RGB. The conversion chain goes: your RGB file → the printer driver converts to CMYK values → the printhead lays down ink dots → the paper absorbs and reflects light back to your eyes. Every step in this chain introduces a shift. The driver’s conversion algorithm is usually the biggest variable — different drivers for the same printer can produce noticeably different color output from identical RGB input.

This test page exists alongside the Color test page because it tests a different thing: not whether your printer can produce accurate colors in general, but specifically how well it reproduces the colors you see on screen. The color bars are set to pure R(255,0,0), G(0,255,0), and B(0,0,255) — the exact colors your monitor displays at maximum channel saturation. Comparing the printout to your screen reveals how much the conversion chain shifts each primary. To see the exact CMYK percentages your driver will request for any RGB value, use the RGB to CMYK converter. For methods to minimize the screen-to-print gap, our calibration guide covers ICC profiles and driver-level color management.

Additive RGB mixing: overlapping red and green produces yellow on screen, but printers use subtractive CMYK instead.

Colors Your Printer Cannot Reproduce

Some RGB colors are physically impossible for a CMYK printer to produce. Electric blue (0, 100, 255), neon green (57, 255, 20), vivid purple (128, 0, 255), and hot pink (255, 105, 180) all fall outside the CMYK gamut. When the driver encounters these out-of-gamut colors, it has to substitute the closest printable alternative — a process called gamut mapping. The result is always a less saturated, less vivid version of the original.

This is not a defect in your printer. It is a fundamental limitation of ink-on-paper color reproduction. Even professional prepress workflows with expanded-gamut printing (using orange and green inks in addition to CMYK) cannot match the full sRGB monitor gamut. If colors on this test page look duller than their screen equivalents, check whether the specific color falls outside the CMYK gamut before blaming your printer or ink. The CMYK test page can confirm whether individual ink channels are performing correctly within their achievable range.

What to Look For

  • Red, Green, and Blue bars should appear vivid and fully saturated with no dullness or color shifting.
  • Gradient blends from black to each primary color should be smooth and free of banding.
  • There should be no cross-contamination between color channels — red areas should have no green or blue tint.
  • White balance should be clean — white areas of the page should remain pure white with no color cast.

Troubleshooting Tips

Why does one RGB color channel appear weak or missing?
Check the corresponding ink cartridges. On CMYK printers, remember that RGB is produced by mixing inks — check both related channels.
Why do my printed colors look dull compared to the screen?
Printers have a smaller color gamut than monitors. Use the highest quality setting and photo paper for best results. Consider an ICC color profile.
What causes visible banding in the gradient strips?
Increase the print resolution to the maximum setting. Run a head alignment utility and ensure you are using compatible paper.
