Hi,
Just got an IP-8720 and it is printing black OK but I need it to print darker. I am printing onto a translucent inkjet film. The part I am printing is used to tightly press against a light-sensitive photoresist file and then exposed to a UV light. The graphic I am printing is needed to block the light from getting through to the photoresist film and is best to use pigment ink but more on that in a sec.
What I found out is I have tried a number of settings to get this to print a dark image but they all seem to end up about the same darkness which is almost a dark, dark gray. I have tried all combos of settings on all sorts of paper types but think these are the way they should be:
- Photo Paper Pro Luster
- Print Quality - High (or higher depending on paper type)
- Grayscale Printing
- Color/Intensity set to Manual
- Brightness - Dark
- Intensity - 50 (Dark as it goes)
- Tone - 0
- Contrast - 0
These are almost identical to the setting the people who make the film say to set a 'Luster' paper on the Epson 15000 they recommend and pigment ink, not dye. The Epson seems to have a DPI setting, Photo RPM (Max dpi), that I do not see for the Canon.
So with the ink, I saw that the main black cartridge, the PGI-250 is a pigment ink to make text 'crisper', and the color cartridges, CLI-251s, are a dye-based ink.
So my question are:
- Can I specify somewhere to use the PGI-250 cartridge or is that an 'automatic' when printing in Grayscale?
- Is there a cartridge with pigment ink that I can replace the CLI-251s with?
- If there is a pigment ink for the CLI-251s will that hurt the printer or jets using the pigment ink?
Anyway thanks so much in advance for any help!
Stay safe and be well!
Dave
