Canon PIXMA PRO-100S Ink Cartridges
Your Canon PIXMA PRO-100S uses the CLI-42 ink cartridge series. The PIXMA PRO-100S is an A3+ professional photo printer designed for vibrant, high-gloss prints and smooth black-and-white tonal transitions using an 8-colour ink system. Ink Depot has been supplying genuine consumables for this printer since Jun 2015. Photo magenta (42PM) and light grey (42LGY) inks often deplete faster during high-saturation portrait runs, making complete CLI-42 bundle sets ideal for maintaining active workflows. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Understanding CLI-42 Ink Consumption
Cartridge yields for the Canon PIXMA PRO-100S are measured using ISO/IEC 29103 photo print testing standards on A3+ paper. Because photo output distributes ink according to image colorimetry, individual colours like grey (42GY) and photo cyan (42PC) deplete unevenly depending on tonal balance.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |

| CLI-42PC | Standard | Cyan | 60 | $0.40 |
| CLI-42C | Standard | Cyan | 58 | $0.23 |

Professional Printing Insight
Always keep extra light grey (42LGY) and grey (42GY) cartridges on hand, as the PIXMA PRO-100S relies heavily on neutral inks even when printing high-contrast colour images to build shadow depth and control colour casts.
Frequently Asked Questions
Why do grey and light grey CLI-42 cartridges run out when I only print colour photos?
The PIXMA PRO-100S uses grey (42GY) and light grey (42LGY) inks across all photographic printing, not just black-and-white jobs. These neutral tones are blended into colour prints to neutralise highlights, reduce graininess, and smooth shadow gradients.
Can I replace individual CLI-42 cartridges, or do I have to swap the whole set at once?
You can replace individual CLI-42 tanks as each colour empties. The printer tracks each ink channel independently, allowing you to swap out spent cartridges like photo magenta (42PM) without disturbing remaining inks.
How does ink consumption differ between photo cyan (42PC) and standard cyan (CLI-42C)?
Photo cyan (42PC) is a lower-density ink formulation used primarily in highlights, sky tones, and mid-tone transitions. Standard cyan (CLI-42C) provides deeper saturation in dark, shadow areas. Consequently, photo cyan typically depletes faster during landscape and portrait printing.
