CMYK Printer Test Page
Print this free CMYK printer test page to check each ink channel — cyan, magenta, yellow and black — individually. The sheet includes pure CMYK blocks, gradient bands, a mixed color grid, registration marks, fine lines and a rich black comparison.

CMYK Printer Test Page
1 · Pure CMYK Blocks
Each block tests one ink channel. A faded or missing block identifies the problem cartridge directly.
2 · CMYK Gradient Bands
Each band fades from 0% to 100% of one ink. Banding or gaps reveal nozzle or supply problems in that channel.
3 · Mixed CMYK Color Grid
Two-ink mixes (blue = C+M, green = C+Y, red = M+Y) test how channels combine. Wrong hues mean one ink is weak.
4 · Registration Marks
On color laser printers, each color's crosshair should sit exactly on center. Offset marks indicate a registration error.
5 · Fine Line Tests (per channel)
Fine colored lines should be continuous and match the intended hue with no fringing.
6 · Rich Black Comparison
Rich black blocks should look deeper and denser than plain K. If all three look identical, the printer may be converting everything to K-only.
How to Use This CMYK Test Page
Printers create every color on the page from just four inks: cyan, magenta, yellow and black (CMYK). This CMYK test page isolates each channel so you can identify exactly which cartridge is causing a problem.
Print in color
Click the print button and make sure color printing is enabled in the print dialog — grayscale mode would defeat the test.
Check pure blocks first
The four pure CMYK blocks tell you immediately if any single ink is low, clogged or missing.
Read the gradient bands
Each band stresses one channel from light to full coverage — the most sensitive test for partial clogs.
Verify the mixes
Blue, green and red are made by mixing two inks. A wrong hue here confirms which channel is weak.
What to Check After Printing
- Four distinct pure blocks: cyan should be a clean sky blue, magenta a vivid pink-red, yellow bright and even, black solid and dense.
- Gradient smoothness: banding in a single channel's gradient means partial nozzle clogging in that channel — run a cleaning cycle.
- Correct mixed hues: C+M should give blue-violet, C+Y green, M+Y red. If green looks yellow-green, cyan is weak; if red looks orange, magenta is weak.
- Aligned registration marks: on color lasers, colored crosshairs that sit off-center reveal registration errors — run the printer's color calibration.
- Continuous fine lines: broken colored lines confirm nozzle problems in the matching channel.
- Rich black depth: the middle and right blocks should print noticeably deeper than plain K, especially on inkjets.
Understanding CMYK vs RGB Printing
Your screen displays colors with red, green and blue light (RGB), but your printer builds colors with cyan, magenta, yellow and black inks (CMYK). Every time you print, the driver translates RGB values into CMYK ink amounts — and that translation is where many color problems appear. Some vivid screen colors, such as bright neon greens and pure electric blues, sit outside what CMYK inks can physically reproduce, so they print slightly duller even on a perfect printer.
That's why this CMYK test page matters: it skips the guesswork by exercising the printer's actual ink channels. If all four pure blocks, all four gradients and the mixed grid print correctly, your hardware is healthy — and any remaining color complaints are about settings, paper or expectations rather than the printer. To test the other side of the translation, print the RGB test page and compare, or use the full color printer test page for a combined overview.
Frequently Asked Questions
CMYK stands for cyan, magenta, yellow and key (black) — the four inks printers combine to reproduce color on paper. Unlike screens, which emit light, paper reflects light, so printers use subtractive inks that each absorb part of the spectrum. Almost every inkjet and color laser printer works this way.
The missing block identifies the failed channel directly. Check that cartridge's ink or toner level first; if it isn't empty, run the printer's head cleaning (inkjet) or remove and reseat the cartridge (laser), then print this page again.
Color laser printers print each color as a separate layer. Registration marks reveal whether those layers line up. If a colored crosshair is visibly shifted from the black one, run the printer's built-in color registration or calibration routine.
Rich black is black printed with a mix of all four inks instead of black ink alone. It looks deeper and denser, which matters for large dark areas in photos and designs. The comparison blocks on this sheet let you see whether your printer produces a visible difference.
