Known bugs and issues

Color cast and metamerism

Solution: Use the correct ICC profile for your specific printer + paper combination. Soft-proof in Photoshop or Lightroom before printing. Avoid generic profiles — always download the exact profile from the paper manufacturer's website.

Band lines in prints

Solution: Run a nozzle check pattern. If missing nozzles appear, perform a head cleaning cycle. For persistent issues, soak the printhead in a cleaning solution.

Ink smearing on glossy paper

Solution: Ensure the printer driver is set to the correct paper type. For glossy/satin papers, use the "photo paper" setting. Allow prints to dry completely before handling (10–15 minutes for pigment inks).

Step-by-step fix procedures

Fix color cast

1. Calibrate your monitor first (6500K, gamma 2.2, 120 cd/m²)
2. Download the ICC profile for your exact printer + paper
3. Open Photoshop/Lightroom and enable soft-proofing
4. Print with "Color Management: Application"
5. Compare print to screen under D50 viewing light

Fix ink smearing

1. Wait for prints to dry completely (10–15 min for pigment inks)
2. Use the correct paper type setting in the driver
3. For glossy papers, use the "photo paper" preset
4. Store prints in archival sleeves away from direct sunlight
